random change meaning in English

随机变化

Regions that are untouched by normal random changes typically are important ones , and thus are conserved by evolution
这些区域并没有发生随机变化，因此被进化完整地保留了下来。
Under finite size of neuronal membrane , the transmembrane potential will fluctuate due to the random changes of conformational state of ion channels embedded in the membrane
在考虑有限大小膜面积时，神经元系统由于膜上通道的随机开关而使神经元本身具有了随机性。
In this thesis we analyze in detail the influence , created by random change of the optical wave polarization , on the output of the interferometer . then several principles of eliminating polarization - induced fading are introduced , and the principle that inserting two faraday rotator mirrors into the end of michelson fiber interferometer to eliminate the fading is analyzed in detail . this method can eliminate polarization - induced fading without additional signal processing , and make the output of the sensor stable
其中,本文详细分析了光波偏振态的随机漂移对干涉仪输出的影响,介绍了目前几种消偏振衰落技术的原理,着重讨论了在光纤michelson干涉仪末端加两个法拉第旋转镜的消偏振衰落的原理,该方法不需要任何附加的信号处理就可以消除偏振衰落,使干涉仪输出稳定。
