pressure rise time

There's added time pressure to the cleanup, as temperatures are expected to rise into the 70s later this week.

另一方面，清理工作也面临着时间压力，因为到本周末，气温预计将高达华氏七十度（约合摄氏二十一度）。

Nitrogen is the inert gases, low expansion coefficient, not easily with the environmental temperature rise for a long time, can maintain normal tire pressure, greatly reduce the flat tire.

氮气是惰性气体，膨胀系数低，不轻易随环境温度上升而上升，可较长时间维持正常胎压，大大降低爆胎几率。

Some characteristic parameters, the maximum explosion pressure, maximum rate of pressure rise and explosion time etc, can be tested exactly by using this experiment system.

根据标准设计了一套哈特曼粉尘爆炸实验装置系统，实现了对最大爆炸压力、最大压力上升速率和爆炸时间等粉尘爆炸特性参数的实验研究。
