The median lethal concentration data is reliable for future biological observation.
为今后的生物监测提供可靠的半致死浓度的数据。
Pretreatment of low temperature could induce resistance to lethal concentration of H2O2.
低温预处理可以诱导对致死浓度h2o2的抗性。
The grades were designed by equal space between logarithm, and the median lethal concentration was computed by Linear Regression.
浓度梯度按等对数间距设置，半致死浓度采用直线内插法进行计算。
The dosage of interest is typically the lethal concentration, known as LC50, that will kill 50% of the population of organisms in a given period of time.
需要测试的剂量是致命浓度(LC50)在给定时间内能杀死50%生物体的剂量。
For copper, she said, the LC50 (the concentration lethal to half of any given species over a certain time) decreases with temperature - meaning that toxicity increases.
她说，对于铜来说，半数致死浓度lc50(一定时间内受试动物半数死亡的毒物浓度)随温度减弱-这就意味着毒性增加。
Through experiments have found that: when the concentration of heavy metals in the soil is 0.5 percentages, it fits the half lethal dose.
通过实验发现：当土壤中重金属的含量为0.5%时，最符合蚯蚓的半数致死量。
