mortalities

Birds, including several threatened species, have been killed in wind turbines, but simple design modifications can limit these mortalities.

有几种已成为受危胁物种的鸟类不断被风力涡轮机杀死，其实简单的设计改进就可以控制这些死亡率。

Conservationists and scientists then claimed that such mass mortalities were not uncommon and there were straightforward explanations.

然后生态保护者和科学家宣称，这些大量死亡事件并不罕见，有很简单的理由。

the emendation mortalities of the test insects were low when water extract and petroleum ether extract were adopted.

水萃取物和石油醚萃取物试虫死亡率低。
