The desirability of providing a high hydrogen injection velocity and a low oxygen injection velocity has been previously discussed . 上面已经讨论过，希望能够提供高的氢喷射速度和低的氧喷射速度。
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。
In light of the hazards and uncertainties associated with subsurface waste disposal, deep well injection may create pollution problems . 由于地表下废水处置的危险性和不可靠性，深井注入也会产生污染。
In light of the hazards and uncertainties associated with subsurface waste disposal, deep well injection may create pollutional problems . 由于地表下废水处置的危险性和不可靠性，深井注入也会产生污染。
Those young children who have not received a booster dose of vaccine in more than a year should receive an injection upon exposure . 一年多没有接受加强剂量疫苗注射的年幼儿童，受暴露时，应接受一次注射。
At any given element spacing, the minimum stable operating hydrogen injection temperature varied linearly with face coverage . 对于任何给定的单元间距，稳定工作的最低氢喷射温度随喷注面覆盖而线性地变化。
Carcinoid flush cannot be reproduced by 5-ht infusion though bradykinin injection will produce a tolerably close imitation . 5HT的输注不能引起类癌性潮红，相反，舒缓激肽的注入则可得到较近似的阳性结果。
It has now been demonstrated that fluid injection schemes can produce a sufficient side force to meet the requirements of many applications . 现在已经证明，流体喷射的方案能产生足以满足很多用途所要求的侧向力。
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。
