Based on the variable separation method, the governing equations for the film thickness problem have been solved. A reasonable consistent condition of the momentum equations has been found and solved. Based on the methods ofmathematical physics, series expansion solution of the velocity filed in the film has been derived. A boundary condition at the boundary of the spray area was given and the velocity slip phenomenon has been considered.

基于电子器件喷雾冷却技术的研究现状和研究热点，本文对喷雾在热源表面形成的冲击液膜流动及厚度模型、基于CHF(Critical Heat Flux，临界热流密度)准则的倾斜喷射喷嘴轨迹、喷嘴距热源换热最优时的高度、倾斜喷射实验以及针对动态喷射的电磁驱动器件的吸合问题等方面进行了研究：针对圆锥形轴对称喷雾冷却系统，在对喷雾区域进行划分的基础上，引入滑流边界条件，在提出圆锥状喷雾假设的基础上，建立了喷雾区域雾滴密度连续介质等效模型。

But if you continue to exist, which can be fitted with a 喷粉器 of corn meal and away from the scanner, the squeeze from 喷粉器 and let it dispersalof in the air, when the high granula powder down, and they took transmissional draft of the piece, let it pass through dusting segment loading fine powder of the air, you can achieve the objective of the Elimination of Newton's rings.

但如果还来活命，可用装有玉米粉的喷粉器，挨近扫描仪，不兵玉米粉从喷粉器洋挤不入，让它在空洋拆散，当不小颗粒的粉粒落下后，拿住透射稿的一角，让它穿功喷粉不天区，这样空洋的粗粉粒落在其上，可以到达打消牛顿环的纲的。

The experimetal results show that the flexural moment of the sample in the prebending direction is far bigger than that in the vertical direction to pre-bending and the spherical shape can be conquered during pre-loading laser peening forming to a great extent.

试验结果表明，在弹性预加载下，板料在弹性预弯方向获得的弯矩要比与弹性预弯垂直方向上的弯矩大得多，弹性预加载下激光喷丸成形可以有效地克服自由状态下激光喷丸件呈球形现象，激光喷丸件的曲率是自由状态下激光喷丸成形曲率的2～3倍；在相同曲率下，弹性预加载下激光喷丸成形件的表面粗糙度比自由状态下激光喷丸成形件的表面粗糙度要低1～2等级，因此弹性预加载下激光喷丸成形要优于自由状态下的激光喷丸成形。

But if that does not work, use some simple methods: part is a with corn flour of 喷粉器, and went to a place away from the scanner, the squeeze from 喷粉器 for the dispersalof from the air, when the high granula powder down, and they took transmissional draft of the piece, let it pass through spraying area, so that the fine powder particles in the air to it, in order to achieve the objective of the Elimination of Newton's rings.

但如果还来活命，那么不离给搁置一些单一的办法：局部是用装有玉米粉的喷粉器，行到挨近扫描仪的不天方，不兵玉米粉从喷粉器洋挤不入来，让它从空洋拆散，当不小颗粒的粉粒落下后，拿住透射稿的一角，让它穿过喷粉不天区，这样，空洋的粗粉粒不离落在其上了，以到达打消牛顿环的纲的。

The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.

进一步采用进气道预喷正庚烷，缸内直喷异辛烷，在没有火花点火和热EGR的辅助下利用预喷正庚烷HCCI燃烧产生活化热氛围的热作用和化学作用引燃缸内直喷高辛烷值燃料异辛烷，系统研究了不同预喷正庚烷当量比和缸内直喷时刻对直喷异辛烷燃烧模式、发动机效率和排放的影响，并用三维CFD耦合化学反应动力学对其燃烧过程进行数值模拟。
