The feeding and excretion of three little fishes (Hemiculter. leucisculus, Tilapia. aurea and Cirrhinus. molitorelld) was studied and their effect on water quality of Qiankeng reservoir in Shenzhen City Around the topdown effect of fish was also studied. Based on the analysis of their stomach contents, their diet composition was assayed. The three fishes" feeding rhythm in cage and their rate of digestion indoor were looked into, and their daily ration was estimated through the method of daily average fullness index. Using the spectrophotometer, the content of chlorophyll a in the stomach was measured, and the feasibility of taking the chlorophyll a as an index of measuring the feeding of fish on phytoplankton was studied. Adopting the national standard method, the effect of the three fishes" excretion on total nitrogen, total phosphorus, CODMn, pH, turbidity and conductivity coefficient was surveyed. The effect of feeding and excretion offish on water quality was discussed and the results revealed as follows:H.

围绕鱼类的下行效应，本文以深圳茜坑水库三种小型鱼类Hemiculter leucisculus罗非鱼Tilapia.aurea和鲮鱼Cirrhmus.molitorella为研究对象，以胃含物分析为基础，分析了三种鱼类的食物组成；调查了网箱中自然状态下三种鱼的摄食节律，在室内调查了三种鱼的食物消化速率，运用日平均饱满指数法计算出三种鱼的日粮；采用分光光度法测定了鱼体肠叶绿素含量，探讨了叶绿素作为鱼类对浮游植物摄食量衡量指标的可行性；采用国家标准的水质测量方法，测定了鱼类排泄对总氮、总磷、高锰酸盐指数、pH、浊度和电导率的影响量。

A field trial was conducted in a greenhouse with soil affected by secondary salinization to explore effects of application of oil cake manure on soil available nutrients, water soluble salts and salt composition, and hence to evaluate feasibility of applying oil cake manure to ameliorate soils affected by secondary salinization, and predict possible consequences of the application of a large amount of oil cake manure in the greenhouse soil.

In the PEMFC system, the oscillogram of the current is stable while the current is 1A; however, when the current is changed into 2.1A (subject to the power is 230W), the current output fluctuates and twists. After comparing the result generated from the simulation test of PSIM and experiment with the real data, this theory of the dissertation is proved to be workable.

本论文之研制之质子交换膜燃料电池电能转换系统，当电流为1A与1.9A时，电流波形图相当稳定，而当电流改变成2.1A时，此时功率约为230W，其输出电流波形及产生扭曲变形较不稳定，经由PSIM软体模拟与实验比较得出稳定燃料电池发电系统，并且与实际量测结果互相比较，以验证本文研究系统之可行性。

During the manufacturing of the critical intermediate cephalosporin nucleus --7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt, first the feasibility of the one-pot synthetic route of open loop, closed loop and ozonization when chlorine is passed over is qualified by experiments. Then the critical factors that will influence this reaction are studied as follows: the mol ratio of triphenyl phosphite and Diphenylmethyl 3-hydroxy-7-phenylacetaminoceph-3-em-4-carboxylate-l-oxide is four to one; the quantity of the stablizer should be at least more than two to one. The temperature of the system must be 25℃ when chlorine is passed over so that the hydrochloride can be precipitated to obtain cephalosporin nucleus of cefaclor--7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt.
