尾草履虫

杂粮培养液培养的尾草履虫长度、宽度都比较大，个体宽短；

The length and width of Paramecium caudatum cultured in grist medium is bigger , the body is dumpy .

Cu2+对尾草履虫的毒性大于Zn2+的毒性；

The toxicity of Cu ~ ( 2 + ) to Paramecium caudatum was stronger than that of Zn ~ ( 2 + ) .

尾草履虫种群增长曲线在水质监测中应用研究

The Investigation on the Population Growth-curve of Paramecium in Nature-culture and Water Quality

采用He&Ne激光辐照经单克隆培养的尾草履虫（Parameciumcauatum）无性繁殖系，观察并分析激光对尾草履虫分裂繁殖产生的影响。

Paramecium caudatum ( P.c. ) cultured by clone was treated with He & Ne laser .

1998年4～6月，对聊城市区主要水域，采用活体采样，研究尾草履虫自然培养中种群增长曲线与水质污染的相关性。

In April to June 1998 , the growth-curve of Paramecium in nature-culture and the pollution degree of water was studied .
