Understanding the sublethal effect of pesticides is important for rational application of pesticides.

The proportion of damaged cells depends on the species of microorganisms, electric field strength and treatment time. S. aureus was the most resistant microorganism which showed the highest sublethal injury proportion.

损伤亚死微生物的比例与微生物的种类、电场强度和处理时间有关。其中金黄色葡萄球菌对PEF的抵抗性最强，产生的损伤亚死细胞也最多。

The result demonstrated that nitrate reducing bacteria and ferro bacteria were killed effectively by the micro electrolyser, the lethal efficiency could be 99% at proper current density and treatment time. The hydroxyl radical produced by the micro electrolyser in water was the main lethal factor.

在适宜的电流密度和适当的处理时间下，对硝酸盐还原菌、铁细菌的杀菌率可以达到99%以上，并初步证实，微电解时水体中产生的·OH自由基是主要的杀菌因子。

To study the lethal equivalent of New Langshan Chicken, we collected the data of hatch rate at first check time, death rate in hatching time, and mortality after hatching.

研究以新狼山鸡12个世代的入孵头照白蛋率、孵化期死亡率、育雏期死亡率和育成期死亡率为基础材料，作为探讨新狼山鸡死亡当量的依据。

The results showed the lethal equivalent was only 0.24%, less than some other breeds. This demonstrated that after several generations by inbreeding its characters were hold.

结果表明，新狼山鸡的死亡当量仅为0.24%，与其它一些品种比较相对较小，说明虽经多个世代的缓慢近交繁育但未发生性状的衰退，在生产中可以大规模扩繁加以合理利用。
