为调查电子垃圾回收活动对当地水生生物造成的多溴联苯醚污染，测定了广东某电子垃圾回收地附近水库中水生生物样品（水蛇、鱼类、草虾和田螺）和对照区样品中18种PBDEs含量，通过对样品氮同位素的测定，探讨了PBDEs在该地淡水食物链上的生物富集特征。

In order to give sufficient data support for the design of terephthalic acid manufacture, corresponding phase equilibria, including solid-liquid equilibrium and vapor-liquid equilibrium, have been determined and studied.Improvements have been made on our former apparatus, which was used for the measurement of solid solubility, for the purpose of getting more precise experimental data in the range of lower solubility. Horizontal stir was changed to magnetic whirly one, which shortened the dissolving time remarkably.

Theoretical analysis reveals that the reaction of the immobilized enzyme of low substrate concentration may be approximated to be of first order, while that of high substrate concentration to be of zero order.

经过对固定化酶反应动力学理论分析可知，实验条件下的低基质浓度区内测定的固定化酶反应可近似地作为一级反应，而在高基质浓度区内测定的固定化酶反应可近似地作为零级反应。

METHODS: The 144 BALB/c male mice were abdominally irradiated with 1150 cGy 60Coγray in 1-3 h, and then they were injected intestinal RNA from normal rats on jejunum. On day 1, 3 and 5 after irradiation,the mice were sacrified after anesthesia for determining endotoxin in blood and bacterial metathetic rate, and intestinal crypt survival rate.

选用BALB/c雄性小鼠144只，用1150 cGy 60Coγ射线进行腹部一次照射，于照后1~3 h采用局部肠腔扩张注入法给小鼠空肠肠腔内注入正常大鼠小肠RNA，分别于照后1，3，5 d麻醉后解剖，取血，测定内毒素含量；取肠系膜淋巴结，测定细菌移位率；取空肠段，计数肠腺存活率。
