Livestock wastewater contains not only high concentration of organics, but also amino acid. This paper studied efficiency of UASB applied in such wastewater, and the influences of environmental and operation conditions on ammoification rate were analyzed. Results show that suitable pH for the bacterium had a wide range from 6. 5 to 8, and pH 7 was the best. A positive correlation was between temperature and ammonification rate, while 38℃ was prefered from an economic point of view. Ammonification rate increased with the influent concentration of increase while there's a contrary situation when the organic load increase.

因畜禽废水除了含有大量的有机物，还含有一定量的氨基酸，因此，研究利用UASB处理畜禽废水，在不同环境条件和工况条件下对氨化率的影响，结果表明：氨化菌适应的pH值范围较宽，在6.5~8.0范围均可以较好的生存，其中以7.0为最佳；温度与氨化率基本成正相关关系，从经济等多种角度考虑，中温阶段38℃为最适宜；氨化率随进水浓度的增加而增加；进水有机负荷越大，氨化率越小。

Since the production of carbon nanotubes synthesized by arc-discharge method contains impurities such as carbon nano-particles, amorphism carbon and graphite fragment, several purification methods were used to purify carbon nanotubes. It is found that with oxidation method in air, we can easily get purified carbon nanotubes.

由于用电弧放电法合成出来的纳米碳管产物中除了有纳米碳管外，还含有一些纳米石墨颗粒、无定形碳和石墨碎片等，因此本文对用电弧放电法合成出的纳米碳管进行了多种方法、探索性的提纯研究，实验结果发现，利用大气氧化法对纳米碳管进行提纯效果好，设备简单，是一种方便实用的方法。

Objective: To study hypoglycemic action of total flavone of Ampelopsis grossedentata from Guangxi by observing the effects of GXTF on blood glucose levels in many strain animal models.
