generatio怎么记

Of all 266 isolates,( 33% to 92%) are resistant to Ampicillin and Cefazolin, In contrast, susceptibility rate of these isolates to Imipenem and the fourth generatio cephalosporins was more than 90%.

分离菌株中耐药性以氨苄西林、头孢唑啉的耐药率最高，达（33%～92%），对亚胺培南、第四代头孢菌素较敏感，敏感率在90%以上。

In the temperature range of the experiment ( 21~ 33 ℃), the survival percentage of whole generatio, the number of eggs laid per female and the index of population increase showed a general trend which can be described by parabolic equations.

在试验温度范围内（21℃－33℃）世代存活率、雌成螨平均产卵量、种群增长指数均呈抛物线趋势，可以用二次抛物线方程表示其随温度的变化情况。

An un-holy battle between the generatio is being waged agai t all adults, and time is not on their side.

一场对抗所有成年人的不神圣战争在几代人间展开，并且时机对大人们不利。
