Authors: Liu Ai Hua , Zhou Shu Xia
Published: September 2014

The tribological properties of TiN coating were studied at the speed of 40m/min-120m/min, under the load of 5N-15N at elevated temperatures between 200°C-600°C. It can be concluded that when the temperature is lower than 400°C, the coefficient of friction increased with temperature, but the value decreased because of the friction oxidation at 600°C.The wear mass loss of the coating increased with increasing of speeds and loads, and this proved the TiN coating was not adaptable to high temperature environment. The wear mechanisms of TiN coating at elevated temperature were abrasive wear, plastic deformation, oxidation wear and adhesion wear.

Authors: Xu Bin Bin , Yamada Shotaro , Noda Toshihiro
Published: September 2014

The soft ground improvement employing vacuum preloading is widely used in Tianjin. In the application of vacuum preloading, the bending of plastic vertical drains (PVDs) often occurs accompanying the large settlement of the soft ground or the significant shear strain at the ground surface. In order to investigate the influence of bending of PVDs on the ground consolidation, three different bending shapes of PVDs are assumed and a series soil-water coupled finite element analyses are carried out. It is found that: 1) the macro-element method is available to take the bending effect of PVDs into consideration; 2) the bending at the bottom of PVDs has much impact on the consolidation of ground even though the hydraulic gradient at the bottom is much smaller than that at the top; 3) Due to the bending of PVDs at the bottom the drainage capacity is much influenced and the volumetric compression only occurs at the first few layers of the ground.

Authors: Liu Yong Hui
Published: September 2014

Polymerase chain reaction (PCR) and fluorescence quantitative polymerase chain reaction (qRT - PCR) is a major means of detection of genetically modified food, whose key is to extract high quality nucleic acid in quick and high flux. The main nucleic acid extraction method is hexadecyl trimethyl ammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) and kits. Because operation of CTAB and SDS method are cumbersome, require the use of organic solvent and centrifugal unceasingly, thus can not meet the requirement of the rapid development of high throughput; and because of the high price of kit method, its application in the daily inspection is also limited. At the same time, the development trend of genetically modified detection based on nucleic acid level is multiple tests; the key is the preparation of different kinds of fluorescent microspheres and specific probe of microspheres. To solve above problems, this paper put forward nucleic acid extraction method on the basis of the magnetic separation technology.

Authors: Li An Feng , Xu Wen Jiang , Ning Yan Ying , Pan Tao
Published: September 2014

This study analyzes the effectiveness of a constructed wetland, including an improved distribution channel, to deal with the eutrophication of water in an urban lake; it was constructed at a conference center in Beijing, China. The improved distribution channel was designed to achieve two complementary objectives for the operation of a constructed wetland: (1) to delay the clogging of a constructed wetland with organic material and (2) to evenly distribute water in the constructed wetland. When backwashing of the improved distribution channel was done, backwashed water flowed onto the surface of the constructed wetland instead of into the sewage pipe networks to reduce the loss of water and supply nutritive matter for wetland plants. Two principles of the design were based on conserving water and on balancing the total phosphorus and were innovatively applied to guide the process design. After 5 years of operation, the eutrophicated water remediation system was found to have successfully improved the water quality of the constructed wetland by reducing total phosphorus, chemical oxygen demand with permanganate index, and total nitrogen and by efficiently delaying blockage of the constructed wetlands by organic materials.

Altitudinal Gradient May Shadow the Effects of Altitudinal Range on Species Diversity
Authors: Li Miao , Feng Jian Meng
Published: September 2014

Altitudinal range is widely used as a proxy of habitat heterogeneity to explain broad-scale geographical patterns of species diversity. Though altitudinal range is a factors derived from altitudinal gradient, altitudinal range’s effects on species diversity on altitudinal gradient remain little known. Based on large scale information of plant species, climatic and geographical factors, we investigated the altitudinal patterns of plant species diversity in the East Himalaya regions, and the effects of altitudinal range on species diversity on altitudinal gradient. We constructed two coefficients, ARDMA (altitudinal range divided by median altitude) and SDDAR (species diversity divided by altitudinal range). We used Spearman’s rank correlation to examine the associations among all of factors. Our results showed that species diversity decreased as the increase of altitude, and significantly related to potential evaporation. No significant correlation was observed between altitudinal range and species diversity, whereas ARDMA significantly related to species diversity, suggesting that only when altitudinal gradient was controlled, were there significant correlations between altitudinal range and species diversity. SDDAR significantly and negatively related to median altitude. We concluded that energy availability significantly affected the altitudinal patterns of species diversity, and altitudinal gradient may shadow the effects of altitudinal range on species diversity.

Authors: Li Xiao Meng , He Li , Song Xin Shuang , Lu Hong Wei
Published: September 2014

In this study, a fuzzy credibility constrained programming (FCCP) model is developed for agricultural irrigation systems management under uncertainty. It is then applied to a real case study in a depression at southern Urumqi, China. The optimization model can be adjusted according to various considerations from decision makers, and thus much optimal and applicable management strategies can be expected through identifying the most appropriate credibility level for the system.

Authors: Chen Su Xin , Li Xu
Published: September 2014

The dynamic performance of spindle unit have a directly influence on the stability of spindle. The 3D model of spindle unit is build in Pro/E and then guided into ANSYS workbench for modal and harmonic response analysis. The inherent frequencies are carried out by modal analysis. And displacement-frequency curves of dynamic response of spindle unit at the front end, in the middle position, at the rear end are carried out respectively. The results of analysis provide reference for spindle design optimization, and also improve the accuracy and working life of spindle unit.
