Physicochemical properties and combustion mechanism of boron are introduced. Long ignitiondelay time and low combustion efficiency are due to the properties of boron itself.
介绍了硼的物理化学特性和燃烧机理，硼的点火延迟期长、燃烧效率低是由其本身的特性所决定的。
2
When the temperature and pressure behind incident shock wave decrease, the photochemical ignitiondelay times will increase.
光化学点火延迟时间随初始爆炸波后温度和压力的降低而增长。
3
The results are better, which show that all portions of propellant are ignited, and the ignitiondelay is shortened.
