查询词典 excretion

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。

The results have shown that for fodders containing different protein levels, the excretion of nitrogen and phosphor was the lowest (34.05%) when the crude protein reached 30%,and the excretion increased gradually otherwise;and for fodders containing different protein qualities,the excretion of nitrogen was the highest,fed with fish meal.

因此测定鱼类氮、磷排泄对研究养殖鱼类对氮、磷的日粮需要和养殖水域环境污染具有重要意义。许多学者从事了这一研究。草鱼作为我国重要经济养殖鱼类，有着较大的养殖面积。草鱼氮、磷排泄情况的研究在国内还未见报道，在国外，C.G。

The excretion of 125I-MT from feces of the calves focus on 29h~37h after affusion. The amount of excretion from feces of the calves was 24.1776% of the total amount of perfusion.

在灌喂后3h开始从粪中检测到125I-MT，33h达最大值（6.4673×10-2 mCi），125I-MT在粪中排出时间相对集中在29~37h时间段；牛粪中125I-MT排出量占总灌喂量的24.1776％。

In 1990, using animal enema technique Cuber discovered that peptide promotes CCK excretion. CCK stimulates the gall bladder's contraction, accelerating the bile excretion.

The energy loss through feces was 0.077C (C: food consumption, KJ/d) and the energy loss through excretion was 0.052C at maximum feeding rate. In that the ratios of F and U to C were low in fish energy budget equation (Cui et al., 1997), the energy loss through feces at optimum feeding rate could be estimated by 0.077C〓(C〓: the optimum feeding rate) and the energy loss through excretion at optimum feeding rate could be estimated by 0.052C〓. The relationship between total energy content for immature gibel carp and body weight was lnE=1. 476+1. 127lnW.

最大摄食率条件下，异育银鲫排粪能损失：F=0.077C，排泄能损失：U=0.052C；由于排粪能及排泄能在能量收支方程中所占比例不大（崔奕波等，1997），最适摄食率条件下的排粪能损失可估计为F〓=0.077C〓（C〓：最适摄食能，KJ/d），排泄能损失可估计为U〓=0.052C〓；性未成熟异育银鲫的能量含量与体重的关系为：lnE=1.476+1.127lnW
