With a gradual contraction longitudinal straight inlet port applied on the Multi-Point Injection natural gas engine, the concentration of natural gas and the pressure field in the intake manifold after the injection of natural gas were investigated, then in the following intake process the volocity vector map and mass distribution of natural gas inside the cylinder were also numerically examined.

在此基础上，考察了渐缩形直进气道应用於多点电喷天然气发动时，天然气喷射后进气岐管内的天然气浓度场和压力场，以及随后天然气-空气混合气在气缸内的质理分布和速度分布。

The conventional development fashions for the gas condensate fields mainly are natural depletion and cyclic gas injection: using the method of gas injection require know clearly about the formation and need more investment, so this method is used few in our country; although a good deal of condensate oil is loss in the formation because of the appearance of retrograde condensation by the method of natural depletion, it is the main development method in China because of the lower investment and lower perception level abut the formation .

凝析气藏主要有衰竭或循环注气两种开发方式：注气开发对地质条件以及资金投入要求较高在我国仅有少数气田采用该方式：虽然采用衰竭开发方式大量的液态烃由于反凝析而损失在地层中，但是由于其低的投资费用、对地质认识程度要求不高，该方式在我国仍然是主要开发方式。

The comparison with the conventional surge tank for a hydropower station with long tailrace tunnel shows that the damping type surge tank with air hole possesses the advantage of higher minimum water level in surge tank with little variation of negative pressure at the outlet of spiral case.
