The critical rateofgasflow from bubble flow to slug flow is an important factor.
泡状流向段塞流转化的临界气体流量是一个非常重要的参数。

The experimental results show that the new valve functions to well in testing the rateofgasflow that it can be applied to the performance testing of ventilators.
试验结果表明，该调节门是一种较为理想的流量调节装置，完全适用于通风机性能测试。
