1.
Since injection density cannot be varied independently, it is difficult to show conclusively its effect on combustion stability.
由于不可能独立地改变喷射密度，要确定地指出喷射密度对燃烧稳定性的影响是很困难的。
2.
Injection density is often used as a rule of thumb to estimate the difficulty of curing resonant combustion.
时常把喷射密度作为一个经验法则来估计解决共振燃烧问题时的困难。
