Because preheat and precool increases the chamber charging pressure before the TDC, which is mechanically counter-productive.
因为预热和效果预冷室收费增加了柜台前，贸发局的压力，这是机械。
The method may optionally include a further step of charging the sealed chamber (12) with a disinfectant gas or vapor.
所述方法还可以选择包括另一个步骤，即向密封腔室（12）内充入消毒剂气体或蒸汽。
The effects of the clearance between the valve and resonance chamber and the valve opening on charging coefficient are also analyzed by simulation;
通过模拟计算分析了控制阀泄漏和开度对充量系数的影响；
