The toxicity of formalin in freshwater to E.coioides was as follows:the semi-anaesthetic concentration was 1 300×10-6 in 5 min and 500×10-6 in 10 min.

淡水福尔马林对斜带石斑的毒性表现为：5 min和10 min的半致死浓度分别为1 300×10-6和500 ×10-6。

The results show that the semilethal temperature decreased.The activity of SOD、POX and the content of Vc increased,leading to increasing of the ability of the membrane protective of scavenging free radical.

结果表明，低温半致死温度降低的同时，SOD、POX活性增强，Vc含量增加，使膜保护系统清除自由基的能力加强，O。

The paper investigates the changes of the semilethal temperature and membrane protective system of Gardenia jasminoides Ellis leaves as temperature fell.

以人工栽培的栀子为材料，研究了其叶片低温半致死温度及膜保护系统随气温下降的变化。

The changes of the semilethal temperature and Abscisic acid,Gibberellic acid in Gardenia jasminoides Ellis leaves as temperature fell wore investigated.

实验以人工栽培的栀子为材料，研究了其叶片低温半致死温度及脱落酸，赤霉素随气温下降的变化。

Howevr,the time of plantlet induction was delayed and the percentage of responding anthers as well as the number of plantlets induced per anther significantly decreased after 3kR of 60Co γ-ray radiation which was considered as a semilethal exposure.

结果表明，1kR左右的γ射线对花粉的出苗率有促进效应；3kR时，花药出苗时间延长，出苗花药率和花药产苗率明显降低，视为半致死剂量；6kR时，虽有部分花药可以出苗，但花药产苗率极低。

To determine cold resistance of Dendrocalamopsis oldhami from four different geographical provenances (Wenzhou, Fu'an, Youxi, and Zhangzhou), changes in semilethal temperature (LT50); peroxidase activities, malondialdehyde, proline and soluble protein content over the course of a winter were compared.

为探明4个绿竹Dendrocalamopsis oldhami地理种源的抗寒特性，测定了它们在越冬期间叶片低温半致死温度(LT50)、过氧化物酶活性、丙二醛、脯氨酸和可溶性蛋白质量分数的动态变化。

Sublethal concetration of cadmium for the common carp is the reference concetration for the acute and subchronic treatment of cadmium.

镉对鲤鱼的半致死浓度是对鲤鱼进行急性和亚急性镉处理的参考浓度。

We conclude that Di-Darg Tang and Vaccaria seed is well tolerated , safe ,and effective ; The test shows that those herbs are more sensitive on Myoma cell , Bcl-2 protein can repress Myoma cell by apoptosis.

子宫肌瘤细胞半致死量浓度(IC50)之测定，较正常子宫细胞低，显示些中药对子宫肌瘤细胞较为敏感，应可经由细胞凋亡的途径，而抑制子宫肌瘤细胞生长。
