Stamped metal keys have been made redundant by ignitions that use start/ stop buttons. 现在用一键启动按钮点火已让模铸金属钥匙变得多余了。
Byvarying the timing of these two ignitions, the proportion of explosiveconsumed by detonation can be altered in a controlled manner. 通过控制两端点燃的时间间隔就可以控制燃烧物产生爆炸的比例。
In order to realize the multiple ignitions of liquid rocket engines reliably, gas dynamic resonance ignition was applied to ignite kerosene/ oxygen. 为了实现液体推进剂火箭发动机的多次可靠起动,将气动谐振点火技术应用于气氧煤油的点火。
Through a series of investigations it was discovered that stray electric current accounted for these ignitions. 得到了发火是由杂散电流引起的结论。
