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(LC)采用直线内插法进行计算。
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(LC)H2O2的抗性。
Median lethal concentration to human embryo lung fibroblastic cell is about 41.3 μ g / ml. 引起半数人胚肺成纤维细胞生长抑制的浓度为41.3μg/ml。
Compared with the single pollution, the eco-toxicity of compound pollution of As + Cd and Cu + Cd becomes stronger, which presents a synergistic effect, as far as the lethal concentration to the cell of duckweed's lamina is concerned; 与单一污染相比,As+Cd和Cu+Cd复合污染对浮萍叶绿素毒性增强,表现为协同作用,加强了对浮萍叶细胞的伤害;
Test on Bacteriostatic Lethal Concentration(LC) and Time of Bio active Compound Produced by Streptomyces 702 链霉菌702生物活性物质抑菌的致死浓度(LC)和致死时间的测定
