title: Spectroscopic properties and discrete multi-wavelength tuning lasers of Nd:GSAG
title: Nd：GSAG光谱及离散可调谐激光

description:  Detailed spectroscopic properties of Nd:GSAG (Gd3Sc2Al3O12) were demonstrated and discrete multi-wavelength tuning lasers were constructed using a birefringence filter for the first time to our knowledge. Because of the disordered crystal field, Stark levels are widened, and the emission cross sections are restrained to different degrees, bringing about a mitigating amplified spontaneous emission and providing optimal conditions for discrete multi-wavelength lasers output. Therefore, Nd:GSAG has the potential to emerge as a laser possessing multiple wavelengths for application as a fundamental laser source.

title: Laser Frequency Shift and Stabilization of Atomic Fountain Based on Electro-optic Modulation
title: 原子喷泉中基于电光调制的激光移频与稳频数据集

description: Laser frequency stabilization is a key technology that affects the performance of atomic fountain systems. A laser frequency stabilization optimization scheme applied to atomic fountain systems has been proposed. This scheme applies the frequency shift method used in the laser cooling process to the frequency stabilization system, generates sidebands through fiber optic electro-optic modulation, and locks the frequency at the saturated absorption peak of the sidebands. Simultaneously applying a large spot saturation absorption module to improve the signal-to-noise ratio of saturation absorption signals and error signals. By utilizing the detection light of the main optical path of the atomic fountain system, the transfer locking from the saturated absorption peak to the saturated absorption peak is achieved through a frequency shift of 1.035GHz, and the cold atomic cloud signal is observed in the fountain system. The locked signal can achieve stable operation for a long time. This scheme has important application value by controlling the electro-optic modulation frequency and also has the potential to achieve arbitrary frequency locking within the range of laser cooling experiments.

description: Knowledge regarding the current state of the environment and environmental issues can serve as a basis for future action. This study recruited elementary school students in Grades 1–2 as subjects, to explore the effects of environmental knowledge on young children's pro-environmental behaviors via ecological worldview and the spillover effect on wild animal conservation. The results show that environmental knowledge has positive influence pro-environmental behaviors through the mediating role of ecological worldview; meanwhile, ecological worldview also have a downstream positive effect on children's wild animal conservation intention, signifying a spillover effect of environmental knowledge which does not directly involve wild animals and its conservation. Accordingly, we discuss the implications for young children's environmental education practices

title: The Bias of Temperature Measurements Based on The Shipborne Rayleigh Scattering Lidar.

description: The data were generated from IDL.Firstly, reference information (including atmospheric density, temperature, pressure, gravitational acceleration, and molecular mass) is derived from the MSISE00 model, and the filename was named 'model_reference' . Then, atmospheric echo signals under different states are simulated, and the temperature under these conditions is calculated using an inversion algorithm. Finally, a conclusion is drawn by comparing the inversion temperature with the reference temperature.The data of inversion temperature were packed in a folder with the same naming convention. The string before the first dash refers to the setted observation angle (0 or 30) of lidar, and number '444' means nothing here. After the second dash, here comes a number varies from 0 to 30. That indicates the pointing of lidar keeps changing and the maximum is 30 degree. FInally, 'delt' follows or not. If the file name contains 'delt', it means that its data is the difference profile between the inversion temperature and the reference temperature, if not, its data is only represented as the inversion temperature profile and other errors.

title: A dataset of GDP spatial distribution on the Qinghai-Tibet Plateau (2020)
title: 2020年青藏高原GDP空间分布数据集

description: Economic spatial distribution data is one of the important indicators for disaster loss assessment. The economy of the Qinghai Tibet Plateau region is relatively backward, and geological disasters occur frequently. Studying the impact of disasters in the region on the economy is of great significance. This study is based on the method of zoning and industry simulation, and establishes corresponding relationships between the GDP of the primary industry and land use types, DEM, village settlements, roads, and river buffer zones. After coupling the GDP of the secondary and tertiary industries with multiple information, spatial models are created for night lighting, building distribution, and interest point data in urban and county areas. Random forest is used to determine the weight of various indicators in the secondary and tertiary industries, calculate the grid value of GDP23, and finally superimpose GDP1 and GDP23 grids to build a 100 m Tibetan Plateau in 2020 × Spatial distribution map of GDP at 100 meters. Using municipal GDP statistical data for accuracy verification, the RMSE is 0.0388, indicating that the data can better reflect the spatial distribution of GDP in the Qinghai Tibet Plateau. This data can provide data support for disaster risk assessment, prevention and reduction in the Qinghai Tibet Plateau.

title: Performance study of Pt-CeO2/ZSM-22 catalyzed n-heptane isomerization reaction
title: Pt-CeO2/ZSM-22催化正庚烷异构化反应性能研究

description: A combination of impregnation and physical mixing methods was used to modulate the sites of the metal active center Pt, which were individually settled onto ZSM-22 molecular sieves or cerium oxide carriers, resulting in Pt-ZSM-22/CeO2 catalysts with atomic–level contacts at the spacing of the metal–acid bicenter sites and Pt-CeO2/ZSM-22 catalysts that maintained nanoscale spacing, respectively. The physical and chemical properties of the two catalysts were characterized by means of spherical differential electron microscopy, XRD, BET, H2–TPR and XPS, and their n-heptane isomerization reaction performance was investigated. In addition, the changes of the physicochemical properties and reaction performance of Pt-CeO2/ZSM-22 catalysts at different reduction temperatures were investigated. The results showed that the metal–acid center maintained nanoscale spacing Pt-CeO2/ZSM-22 catalyst had higher n-heptane isomerization activity and isomeric hydrocarbon yield, which could be attributed to the atomic–level dispersion of Pt on the CeO2 carrier. During the reduction of Pt-CeO2/ZSM-22 catalyst, the release of more oxygen vacancies from the CeO2 carrier helps to retard the aggregation of metal Pt and facilitates the adsorption of heptane molecules. When the reduction pretreatment temperature was 300 °C, the heptane conversion and heptane isomerization hydrocarbon yield were 79.2% and 75.4%, respectively, and the isomerization selectivity reached 95.2%.
