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。

MAIN OUTCOME MEASURES: The seeded cells were observed under inverted microscope; at 1, 2, 3 weeks after seeding, the BMSCs were treated with 4% paraformaldehyde and stained with hematoxylin-eosin; The protein content in seeded cells was determined by bicinchoninic acid assay, and the content of DNA was quantified using Hoechst33258 assay at 5, 10, 14 days after culture.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
