accidental conditions meaning in Chinese

事故情况

Under this condition , this thesis offers a study on cavitation characteristics caused by two main accidental conditions : power off and system fluid off
本文即是针对动力失灵和系统断流两种主要事故工况下，所引起的动力系统中空穴的特性作以研究。
An accidental condition that causes device , component or element to fail to perform in a required manner . the fault may be either physical or logical
使设备、部件或元件不能按所要求的方式运行的一种意外情况。故障可能是物理上的，也可能是逻辑上的。
Therefore , sequential research on chf is necessary . when in accidental conditions of nuclear reactor , the mass flux of coolant is very low . in such condition , the steam quality is high , and the mechanism of chf is mainly controlled by bulk flow , whereas microcosmic parameters near the chf area are affected by the flow conditions in whole tube which called " upstream memory effect "
在反应堆事故工况下，冷却剂流量很低，含汽量很高，其临界机制与正常运行工况下的临界机制有所不同，不仅是一种主流控制临界工况，更由于其局部的各微观参数受上游流道的累积效果的影响而存在上游记忆效应。
