| 2. | Some stratification exists in the spray produced by any liquid propellant injector .
由任何液体推进剂喷注器所产生的喷雾都存在某些成层现象。
|
| 3. | Chamber compatibility and injector durability involve the control of the combustion environment .
室相容性和喷注器耐久性包括对燃烧环境的控制。

| 4. | Momentum of the injector effluent streams can contribute to lateral flow, either intentionally or unintentionally .
喷注器单元喷注射流的动量可能有意或无意地影响横向流。
|
| 5. | The application of a pressure difference across an injector does not cause an immediate velocity response of the liquid propellant .
经过喷注器的压降发生变化时并不马上引起液体推进剂速度变化。
|
| 6. | 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。
|
| 7. | It is likely that such a coarse injector pattern would not have sufficiently high steady-state performance, and so would be unacceptable .
这样粗大的喷注器型式不会有足够高的稳态性能，因此不宜采用。
