1.3 抗生素后效应的作用机制 细菌在抗生素后效应期(PA phase)可产生多种变化,如细菌形态学改变,菌 体电荷分布改变,菌体表面性质改变,酶与非酶蛋白活性改变等.

The results showed that there was slight chemical reaction between NBR and PA under high temperature and high shear rate, but the chemical reaction did not influence on the process of phase reversion.
结果表明，NBR与PA在高温、高剪切作用下，两相界面之间可发生微化学反应，但并不影响动态硫化时两相之间的相态反转过程。
In the blend fiber, stretching benefit to phase transiting of PVDF, but not PA11, and quenching benefit to phase transiting of PA 11, but not PVDF.
但拉伸对共混纤维中PA11的晶型转变影响较小而淬火却有利于PA11的晶型转变，但对其中的PVDF晶型转变影响不大。
