- minimum lethal oxygen concentration 最低致死氧浓度
- The 50 lethal dose of rat by celiac injection is 670.04 mg/kg , and minimum lethal dose of ora is greater than 2 000 mg/kg. 该色素在小鼠腹腔注射的LD50为670 04mg/kg;口服最小致死量大于2000mg/kg.
- By the changes of chlorophyll content, the lethal concentration of Hg to Egeria najas was 0.10-2.00mg/L. 处理48h以后，Hg~(2+)浓度人于1.;00mg/L实验组中的叶片褪绿严重而且叶片相互粘连，叶片叶绿素含量明显低于对照组，从中可以粗略看出Hg(2-)对细叶蜈蚣草的致死浓度为0
- By the changes of the activity of SOD and CAT, the lethal concentration of Hg to Egeria najas was 0.10-1.00mg/L. 以SOD和CAT活性变化为根据，可以推断Hg~(2+)对细叶蜈蚣草的致死浓度为0.;10-1
- 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。
- There is negative correlation between lethal concentration 50%(LC50) of the leachate and COD. 渗滤液的半致死浓度(LC50)与COD呈负相关,其常规理化指标并不能完全反映渗滤液在环境中的生物毒性;
- And the values of 48 h median lethal concentration ( LC 50 ) and safe concentration ( SC ) of methamidophos for European eel larvae were 35.9 mg/L and 3.6 mg/L respectively. 甲胺磷乳剂对欧洲鳗仔鳗的半致死浓度（48h－LC50）为35.;9mg/L，安全浓度（SC）为3
- minimum lethal herbicide dosage ( MLHD ) 最低致死剂量
- At the treatment of the sublethal dosage and median lethal concentration, the comparison between the life of female and male adult and the ck was non significant or they could be prolonged. 结果显示：高浓度下，寿命缩短；
- ALC = approximate lethal concentration 接近致死浓度
- lethal concentration low (LC LO) 最低致死浓度
- lowest published lethal concentration 公布的最低致死浓度
- We have pared down our expenses to a bare minimum. 我们已最大限度地削减了开支。
- median lethal concentration ( LD50 ) 半致死浓度
- The class needs a minimum of 6 pupils to continue. 这个班最低限度要六个学生才可以继续办下去。
