Addition of citric acid significantly increased the WSI of extrudate with and without guar gum from 61. 45％ to 87. 47％ and 56. 26％r to 74. 82％ respectively.

添加柠檬酸能显著提高产物的WSI，以不加瓜尔豆胶的和添加瓜尔豆胶的淀粉挤压样品为空白对照，分别从56.26％和61.45％提高到74.82和87.47％。

Gravimetric analysis and electrochemical results show that the deposition rate displays similar trend,i.e.,the deposition rate increases with the increase of(NH4)3C6H5O7 content.

重量法和电化学法测试所得的沉积速率表现出相似的趋势，即镀层沉积速率随着镀液中柠檬酸三氨含量的增大而增大。

Similar studies between two additives of citrate and ethylene glycol were also conducted.

还对柠檬酸和乙二醇两种添加剂进行了类似的对比研究。

In this study, we used poly L-latcide, poly DL-latcide-co-glycolide 75:25 (PLGA7525) and poly DL-latcide-co-glycolide 50:50 (PLGA5050) during citric acid inducing ammonium bicarbonate gas forming process to form porous polymer film, and rolled the porous polymer film to make nerve conduits with pores and multi-layered. Electron Spectroscopy for Chemical Analyzer and Attenuated Total Reflectance – Fourier-Transform Infrared Spectrometer were employed for determining elements' functionabilities and chemical compounds. Charge Coupled Device camera and Scanning Electron Microscope were employed for macroscopic and microscopic morphologies and structural observation. Differential Scanning Calorimetry was employed for measuring glass-transition temperature. Nano-indentation system was employed for measuring elastic modulus and hardness. Biodegradation and water absorption ratios were measured to analyze their chemical properties and SEM was employed for microscopic morphology of the tested nerve conduit.

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
