4) mortality
[英][mɔ:'tæləti] [美][mɔr'tælətɪ]
致死
1.

6) inactivation
[in,ækti'veiʃən]
致死
1.
In order to solve this problem,Saccharomyces cerevisiae was chosen as the object to reveal the effects of three ultrasonic parameters on the inactivation of yeast cells.
文中以酿酒酵母为对象,考察超声杀菌处理效果的三个主要影响因素(即超声功率、时间和脉冲占空比)对细胞致死作用的影响规律,并采用选择性平板法对超声引起的细胞亚致死效应进行检测,采用TEM对细胞超微结构变化进行检测。
2.
The process can be divided into two stages based on the rate of inactivation: the rate of inactivation was slow at the early stage and increased sharply at the latter stage.
