串接石墨化产品理化指标控制方法的初步探讨

串接石墨化工艺因节电、节料,石墨化产品均质性好、生产周期短等优点,近几年来,已被越来越多的石墨电极生产厂家所应用。随着串接石墨化技术的不断成熟和提高,大家对生产中的主要质量问题,如电极整体纵裂、端部裂纹、端部氧化、表面氧化和麻面、表面侵蚀及理化指标电阻率偏高等都进行了详尽的探讨,并在实际生产中很好地给予了解决,但对炭电极在串接石墨化炉与艾奇逊石墨化炉石墨化后,主要理化指标如体积密度、抗折强度及弹性模量等的差异情况及控制方法探讨较少,笔者根据近年来自己的一些实践总结和体会,以体积密度和抗折强度为主对上述理化指标在串接石墨化出现的与艾奇逊石墨化炉石墨化的差异情况及控制方法进行了初步探讨,期望对同行业的生产起到一定的借鉴作用。
大动脉炎累及冠状动脉的临床特点与诊治

大动脉炎是一种罕见的慢性非特异性血管炎,主要侵犯主动脉及其主要分支,其中约10%~30%的病例可累及冠状动脉(冠脉)造成严重临床后果。大动脉炎累及冠脉时多表现为冠脉开口或近端的狭窄和闭塞。无创影像诊断技术的进展使该病的早期诊断和监测水平得到提高。计算机断层扫描(CT)与核磁共振(MRI)可以发现狭窄前的管壁炎症损伤。尽管糖皮质激素和免疫抑制剂可以改善大动脉炎的症状,但药物减量后仍然容易复发。血管成形术早期通畅率较满意,但中远期再狭窄率仍然很高。药物涂层支架可能成为解决再狭窄问题的一个新途径。
氧化型低密度脂蛋白胆固醇与动脉粥样硬化

动脉粥样硬化(AS)的形成过程复杂,其发病机制涉及炎症反应、脂质代谢失调及氧化应激等多种病理生理机制。其中,低密度脂蛋白(LDL)经氧化修饰后形成氧化型低密度脂蛋白(oxLDL)被认为是AS发生的关键启动因素。大量研究表明,oxLDL的细胞毒性作用可引起血管内皮细胞功能和结构改变,导致内皮细胞变性、坏死和脱落,破坏血管内皮完整性;血液中的单核细胞及LDL通过损伤的血管内皮进入内膜下加速脂质条纹的形成;oxLDL还可刺激内皮细胞和单核细胞/巨噬细胞分泌多种炎症因子、趋化因子及粘附分子,增强单核细胞和T淋巴细胞粘附及向内膜下移行;进入内膜下的单核细胞与内皮细胞粘附,最终分化为巨噬细胞;此外,oxLDL尚可上调巨噬细胞表面的清道夫受体数量并被其过度摄取,导致胞内大量胆固醇聚集进而形成泡沫细胞;大量泡沫细胞停留在血管壁内,使动脉粥样硬化斑块得以形成。
雨生红球藻抗氧化系统对活性氧的清除机制

雨生红球藻(Haematococcus pluvialis)是一种淡水单细胞绿藻,隶属绿藻门、团藻目、红球藻科、红球藻属。它受强光、氮饥饿、高盐等胁迫时积累大量的虾青素,含量可高达细胞干重的6.0%以上~([1])。相关研究也显示来虾青素具有极强的抗氧化活性~([2-4]),它的抗氧化活性较α-生育酚强千倍~([5]),比维生素E高近百倍~([6])。雨生红球藻产生的虾青素可能被用作抗氧化剂消除细胞内的氧自由基等活性氧(ROS)~([7])。活性氧主要包括超氧阴离子、过氧化氢、羟基自由基、过氧化氢、脂质过氧化物和单线态氧等~([8, 9]),它们会引发细胞大分子的氧化损伤~([10-12])。细胞可能存在两套清除活性氧的防御体系:一类为酶促系统,包括超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GSH-PX)等;另一类为非酶促系统,包括维生素、氨基酸、金属蛋白质和类胡萝卜素等~([13-15])。机体内活性氧的产生和清除处于动态平衡,受环境等不良因素影响,活性氧的种类和含量会不断增加,引发脂质过氧化、DNA链断裂、碱基突变和蛋白质的损伤等,细胞内的防御体系则释放更多的抗氧化酶或抗氧化物质,提高细胞内的抗氧化能力,清除活性氧,使体内活性氧的产生和清除再次达到平衡~([16,17])。
太湖流域稻麦轮作农田氮肥施用状况、问题和对策

分别于2006年和2011年在苏南常熟市和宜兴市开展了稻麦农田的氮肥施用状况调查。结果显示,常熟2006年稻季平均施氮量为N 329 kg/hm~2,2011年则降低为N 264 kg/hm~2;麦季变化不大,相应分别为N 216 kg/hm~2和N 230 kg/hm~2。2011年宜兴市稻麦季平均施氮量分别为N 326 kg/hm~2和N 300 kg/hm~2,高于常熟。通过农户种田面积调查分析,近5年来规模化种植大户的出现和不断扩大是驱动常熟市施氮量下降的主要原因,而宜兴市较高的施氮水平与该市仍以散户分散经营种植有关。氮肥品种结构调查表明,该区氮肥施用呈现"以尿素为主导、高浓度复混肥施用比例增加、碳酸氢铵逐步减少、有机肥基本弃用"的格局。基于目前氮肥施用量和结构的变化,从科学和政策两个层面提出了逐步改变当前太湖流域稻麦农田传统粗放种植模式和施氮习惯的对策。
Ovipositional preference and larval performance of poplar defoliator,Clostera restitura on different poplar clones in north-western India

We evaluated ten poplar clones (G-3, G-48, L-50/88, L-154/84, L-156/89, S7C8, S7C15,WSL-22, WSL-29 and Uday) for ovipositional preference and larval performance of Clostera restitura. Female moths did not show any preference with respect to clones for oviposition. Significant differences were observed for number of eggs laidon different plant parts. C. restitura laid eggs in clusters, preferably onupper surface of leaf and size of the egg cluster varied from 15 to 167eggs. Clones varied for their relative resistance and susceptibility to C.restitura. L-50/88; L-156/89 were identified as most resistant clone basedon minimum leaf consumption, whereas S7C15 was found to be most susceptible clone to C. restitura. In multiple choice experiments, no feeding preference by C. restitura larvae was detected amongst different poplar clones. After initial settlement of larvae on a particular clone, thelarvae remained confined to that clone and negligible inter-clonal movement was noticed subsequently. The fresh pupal weight was correlated negatively (r = 0.37) with percentage surface leaf area eaten and positively (r = 0.47) with length of larval period, measured on different clones. Relationship between percentage leaf area eaten and length of larval period was negative (r = 0.23). Owing to relative resistance of L-50/88 and L-156/89 against C. restitura, these clones can be recommended for plantation in defoliator prone areas in north-western India.
Variations in wood anatomical properties and specific gravity of half sib progenies of Populus deltoides

We studied radial and inter-progeny variations in the dimensions of the wood elements and specific gravity of 21 half sib progenies of Populus deltoides Bartr. ex Marsh. The female parents of half sibprogenies were G48 and S7C13 clones. Variance ratio (F) test indicated that inter-progeny variations in the dimensions of wood elements andspecific gravity were significant for all wood traits while variations were significant for radial location for specific gravity only. Hierarchical cluster analysis was done by Squared Euclidean Distance for all of 21 progenies considering six wood traits. 21 progenies were grouped into 4 clusters. Cluster 1 was the largest cluster with 11 progenies, whereas cluster 3 had only one progeny. Selected progenies in clusters 3 (progeny 155,male) and 4 (progeny 108, 196, both female) were highly divergent from the other progenies so they were used in combinations as parents of hybrids to develop new clones with desired characters. Progeny 155 showed higher growth, fiber dimensions, and specific gravity, thus,should be used for the development of new clones.
Modeling susceptibility to deforestation of remaining ecosystems in North Central Mexico with logistic regression

Determining underlying factors that foster deforestation and delineating forest areas by levels of susceptibility are of the main challenges when defining policies for forest management and planning at regional scale. The susceptibility to deforestation of remaining forest ecosystems (shrubland, temperate forest and rainforest) was conducted in the state of San Luis Potosi, located in north central Mexico. Spatial analysis techniques were used to detect the deforested areas in the study area during 1993-2007. Logistic regression was used to relate explanatory variables (such as social, investment, forest production, biophysical and proximity factors) with susceptibility to deforestation to construct predictive models with two focuses: general and by biogeographical zone.In all models, deforestation has positive correlation with distance to rainfed agriculture, and negative correlation with slope, distance to roads and distance to towns. Other variables were significant in some cases, but in others they had dual relationships, which varied in each biogeographical zone. The results show that the remaining rainforest of Huastecaregion is highly susceptible to deforestation. Both approaches show that more than 70% of the current rainforest area has high and very high levels of susceptibility to deforestation. The values represent a serious concern with global warming whether tree carbon is released to atmosphere. However, after some considerations, encouraging forest environmental services appears to be the best alternative to achieve sustainable forest management.

多发伤MSCT检查质量控制“一体化”模式的建立与应用

近年来,创伤造成的人类死亡呈逐年上升趋势,因此,创伤成为危害人类健康重要问题之一,并对社会带来巨大的经济负担。最近10年医学影像技术得到了快速发展,相继推出了多层螺旋CT(multislice CT,MSCT)、双源CT(dual sourceCT,DSCT),MSCT在多发伤检查中的应用是一种革命性进步,能在极短时间内、单一检查方法、单一检查体位完成多部位多系统检查,已逐渐广泛用于创伤患者的伤情评估,被公认为是目前评估多发伤的首选检查方法,使多发伤的病死率由最初的40%下降至10%,因此,MSCT是多发伤影像学诊断方法中效率最高,是缩短院内术前时间的有效方法。本院是全国唯一的正师职野战外科研究所,有创伤-烧伤-复合伤国家重点实验室和全军战创伤救治临床专科中心,拥有世界上最先进的64排MSCT、256层极速CT,常年接受数百例多发伤患者的检查与治疗,在诊断上取得突破性进展。但是,检查前准备是否充分、流程是否合理、制度是否健全、质量指标是否可靠、检查中的配合是否默契,将直接决定检查时间的长短、图像质量的好坏或患者的安全。因此,探索多发伤MSCT检查质量控制“一体化”模式的方法是一项关乎患者检查效果的重要课题,现借鉴本院多发伤MSCT检查的研究成果,结合多发伤MSCT检查现状和存在的问题对其规范化管理进行了初步探讨,以供同行借鉴。

Properties,Morphology and Structure of BPDA/PPD/TFMB Polyimide Fibers

The mechanical properties of fibers were notably improved by incorporating 2,2’-bis(trifluoromethyl)benzidine(TFMB) into 3,3’,4,4’-biphenyltetracarboxylic dianhydride(s-BPDA) and p-phenylenediamine(PPD) backbone.The best strength and modulus of BPDA/PPD/TFMB polyimide(PI) fiber(diamine molar ratio of PPD/TFMB= 90/10) were 1.60 and 90 GPa,respectively,which was over two times that of BPDA/PPD PI fiber.SEM image showed that the cross-section of fibers at each stage was round and voids free.Besides,the "skin-core" and microfibrillar structure were not observed.The thermal properties of PI fibers were also investigated.The results showed that the fibers owned excellent thermal stability,moreover,the structural homogeneity of fibers were significantly improved by heat-drawn stage.The T_g values were found to be around 300 °C by dynamic mechanical analysis(DMA).Wide angle X-ray diffraction(WAXD) and small angle X-ray scattering(SAXS) experiments indicated that the order degree of longitudinal and lateral stacks,the molecular orientation and the structural homogeneity of fibers were improved in the preparation process of fibers.
Novel Iridium Complex with Carbazol-2-yl-β-diketone Derivative:Low-energy Excitation and Red Electrophosphorescent Devices

A novel iridium-complex,(BPPBI)_2 Ir(2-TFDBC)[BPPBI=2-(biphenyl-4-yl)-1-phenyl-1H-benzo[d]imidazole,2-TFDBC=1-(9-ethyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dione],was synthesized,and its structure and component were confirmed by ~1H NMR and element analysis,respectively.UV-Vis absorption and photoluminescent(PL) spectra of(BPPBI)_2 Ir(2-TFDBC) in dichloromethane were investigated.The Ir-complex exhibited a long wavelength excitation of 470 nm,i.e.,low-energy excitation.So,it is a promising candidate for phosphorescent probe and PL material.(BPPBI)_2Ir(2-TFDBC)-based electroluminescent devices,ITO/MoO_3(10 nm)/NPB(80 nm)/CBP:x(BPPBI)_2Ir(2-TFDBC)(20 nm)/TPBi(45 nm)/LiF/Al,were fabricated,where x(%) was of 4% or 8% doping concentration(mass fraction);ITO=indium tin oxides;NBP=N,N’-bis-(1-naphthalenyl)-N,N’-bis-phenyl-(1,1’-biphenyl)4,4’-diamine,CBP=4,4’-bis(N-carbazolyl)-1,1’-biphenyl,TPBi=1,3,5-tris(1-phenyl-1H-benzimidazol-2-yl)benzene.The devices showed a red emission of 620 nm.The maximum current efficiency and brightness were 1.7 cd/A and 4063 cd/m~2 for a device of 8%(mass fraction) doping level,respectively.The moderate luminous efficiency was due to the inadequate energy transfer from the host material to the guest material.
Biodiesel Production from Crude Jatropha curcas L.Oil with Trace Acid Catalyst

Biodiesel produced from crude Jatropha curcas L.oil with trace sulfuric acid catalyst(0.02%-0.08% oil) was investigated at 135-184 ℃.Both esterification and transesterification can be well carried out simultane-ously.Factors affecting the process were investigated,which included the reaction temperature,reaction time,the molar ratio of alcohol to oil,catalyst amount,water content,free fatty acid(FFA) and fatty acid methyl ester(FAME) content.Under the conditions at 165 ℃,0.06%(by mass) H_2SO_4 of the oil mass,1.6 MPa and 20:1 methanol/oil ratio,the yield of glycerol reached 84.8% in 2 hours.FFA and FAME showed positive effect on the transesterification in certain extent.The water mass content below 1.0% did not show a noticeable effect on trans-esterification.Reaction kinetics in the range of 155 ℃ to 175 ℃ was also measured.
盘状半月板损伤法医学鉴定2例

盘状半月板又称盘状软骨,在个体发育中较为常见,通常将其看作变异,因半月板异常增大、增厚如盘状而得名,但并非所有盘状半月板均呈盘状。根据盘状半月板形态不同,Watanabe将其分为完全型、不完全型和Wrisberg韧带型,王淑丽等则将其分为板型、楔型和肥角型。在非剧烈运动的状态下,它仍具有稳定、协调膝关节的作用,且在未损伤时可无症状,特别是形态变化较少的楔形或类正常形盘状半月板可以长期无膝关节功能障碍。
钳刮术引产致宫颈肿瘤出血死亡1例

宫颈肿瘤(cervical cancer)是最常见的女性生殖系统肿瘤。近年来,随着宫颈肿瘤发病的年轻化趋势,育龄妇女罹患宫颈肿瘤增多,妊娠合并宫颈肿瘤也越来越常见,但因漏诊并采用错误方法引产,导致刮破宫颈肿瘤组织出血致死亡的案例尚不多见。本例死者在钳刮术引产死胎过程中突发抽搐及意识丧失,首先考虑羊水栓塞(amniotic fluid embolism,AFE)及产时子痫的可能。其中AFE是极其严重的分娩并发,为孕产妇死亡的重要原因之一,发生率为1/80000~1/8 000,死亡率高达80%以上[1]。但本例在引产术中未出现急性心肺功能衰竭等AFE典型症状,且在对肺及其他各器官的病理切片检查中均未见羊水成分,无法认定存在AFE。本例死者入院后无蛋白尿,查体BP仅为13.3/8.00 kPa(100/60mmHg),子痫诊断标准为BP高于18.7/12.0 kPa(140/90 mmHg),蛋白尿≥300 mg/24 h或定性试验阳性,因此亦可排除产时子痫的可能。对死者手术切除的子宫进行法医病理检验时发现宫颈黏膜大片状出血,后经组织病理学检验证实为宫颈低分化鳞癌。提示本例死者钳刮术中突发抽搐及意识丧失与钳刮术直接伤及宫颈肿瘤组织有关。
Holocene Climate Cycles in Northwest Margin of Asian Monsoon

In the mid-latitude regions of the Asian continent,Zhuye Lake is located in the northwest margin of the Asian monsoon,where the modern climate is affected by the Asian monsoon and Westerlies.In this study,we investigated the absolutely dated Holocene records in Zhuye Lake for detecting the Holocene climate cycles.Totally,~(14)14 C dates and 6 optically simulated luminescence(OSL) dates are obtained from the QTH01 and QTH02 sections.The proxies of grain-size,total organic carbon content(TOC),C/N and δ ~(13)C are used for wavelet analysis,and the results show obvious ~256,~512 and ~1024-year climate cycles,which are consistent with the Holocene millennial and centennial scale climate cycles in the typical Asian summer monsoon domain.In different parts of the Zhuye Lake,the Holocene sediments show variable climate cycles that are affected by the lake basin topography.In the Zhuye Lake,the Holocene climate cycles are mainly correlated with the solar-related Asian summer monsoon variability and the North Atlantic ice-rafting events.
Estimation of Regional Evapotranspiration in Alpine Area and Its Response to Land Use Change:A Case Study in Three-River Headwaters Region of Qinghai-Tibet Plateau,China

Three-River Headwaters(TRH) region involved in this paper refers to the source region of the Changjiang(Yangtze) River,the Huanghe(Yellow) River and the Lancang River in China.Taking the TRH region of the Qinghai-Tibet Plateau as a case,the annual evapotranspiration(ET) model developed by Zhang et al.(2001) was applied to evaluate mean annual ET in the alpine area,and the response of annual ET to land use change was analyzed.The plant-available water coefficient(w) of Zhang’s model was revised by using vegetation-temperature condition index(VTCI) before annual ET was calculated in alpine area.The future land use scenario,an input of ET model,was spatially simulated by using the conversion of land use and its effects at small regional extent(CLUE-S) to study the response of ET to land use change.Results show that the relative errors between the simulated ET and that calculated by using water balance equation were 3.81% and the index of agreement was 0.69.This indicates that Zhang’s ET model based on revised plant-available water coefficient is a scientific and practical tool to estimate the annual ET in the alpine area.The annual ET in 2000 in the study area was 221.2 mm,11.6 mm more than that in 1980.Average annual ET decreased from southeast to northwest,but the change of annual ET between 1980 and 2000 increased from southeast to northwest.As a vast and sparsely populated area,the population in the TRH region was extremely unbalanced and land use change was concentrated in very small regions.Thus,land use change had little effect on total annual ET in the study area but a great impact on its spatial distribution,and the effect of land use change on ET decreased with increasing precipitation.ET was most sensitive to the interconversion between forest and unused land,and was least sensitive to the interconversion between cropland and low-covered grassland.

Relative specificity of acupuncture reinforcing and reducing methods

OBJECTIVE:To probe the effects of acupuncture reinforcing and reducing methods on the human body.METHODS:Studied acupuncture reinforcing and reducing actions in the ancient literature,based on modern clinical and experimental studies,in combination with experience of acupuncture teaching and clinical treatment.RESULTS:The key to the generation of reinforcing and reducing actions is not the acupuncture reinforcing and reducing methods themselves,but instead the functional state of the patient during the acupuncture.When reinforcing and reducing methods act on the human body,a reinforcing-reducing effect is produced through regulation of Qi,indicating that the production of the reinforcing-reducing effect requires a certain condition.Specifically,acupuncture does not produce the reinforcing-reducing effect under all conditions,but can produce a reinforcing effect in patients with deficiency syndrome and a reducing effect in patients with excess syndrome.CONCLUSION:Reinforcing and reducing methods each have therapeutic effects on both deficiency syndrome and excess syndrome,but a reinforcing method should be selected first for deficiency syndrome and a reducing method should be selected first for excess syndrome.
Zero Energy Anomaly in One-Dimensional Anderson Lattice with Exponentially Correlated Weak Diagonal Disorder

We calculated numerically the localization length of one-dimensional Anderson model with correlated diagonal disorder. For zero energy point in the weak disorder limit, we showed that the localization length changes continuously as the correlation of the disorder increases. We found that higher order terms of the correlation must be included into the current perturbation result in order to give the correct localization length, and to connect smoothly the anomaly at zero correlation with the perturbation result for large correlation.
Heat Generation by Electrical Current in Quantum Dot System with Fano Resonance

We study the heat generation in quantum dot system with Fano resonance by nonequilibrium Green’s functions method. The Fano resonance influences the heat generation significantly. As ξ increases, the heat generation decreases gradually. From the study of Q-eV curves, we find that the linewidth function Γ has huge influence on the heat generation. The Q-eV curves display obvious steps when the linewidth function Γ is small. However, these steps disappear with Γ increasing. As the source-drain bias eV increases, the Q-eV_g curves also display interesting behaviors.
Approximate Solutions of Nonlinear Fractional Kolmogorov-Petrovskii-Piskunov Equations Using an Enhanced Algorithm of the Generalized Two-Dimensional Differential Transform Method

By constructing the iterative formula with a so-called convergence-control parameter, the generalized two-dimensional differential transform method is improved. With the enhanced technique, the nonlinear fractional Kolmogorov-Petrovskii-Piskunov equations are dealt analytically and approximate solutions are derived. The results show that the employed approach is a promising tool for solving many nonlinear fractional partial differential equations. The algorithm described in this work is expected to be employed to solve more problems in fractional calculus.
MUSIC ALGORITHM FOR LOCATING POINT-LIKE SCATTERERS CONTAINED IN A SAMPLE ON FLAT SUBSTRATE

In this paper, we consider a MUSIC algorithm for locating point-like scatterers contained in a sample on flat substrate. Based on an asymptotic expansion of the scattering amplitude proposed by Ammari et al., the reconstruction problem can be reduced to a calculation of Green function corresponding to the background medium. In addition, we use an explicit formulation of Green function in the MUSIC algorithm to simplify the calculation when the cross-section of sample is a half-disc. Numerical experiments are included to demonstrate the feasibility of this method.
