Also, two unique injector types, representing departures from the conventional axial injection scheme, are also discussed. 此外，还讨论了两种独特的喷注器型式，这些型式不同于常规的轴向喷射方式。
It is difficult to separate the effects on stability of the propellant properties from those of the injection scheme. 要把推进剂性质对稳定性的影响与喷射型式的影响分开是困难的。
