结果表明，超重力能够强化析氢反应和析氯反应的进行；相对于常重力条件，气泡更容易从电解液中溢出，溶液电阻随重力系数增加而降低；氯碱电解槽电压也随重力系数的增加而降低，并且电流密度越大，槽电压降低的程度越大。

The results show that when gravity wave's propagating in the homogenous winds, the nonlinearity is stronger in the fair wind than in the contrary wind, the background winds change the propagation velocity and path, and when gravity wave's propagating in the homogenous winds, the vertical wavelength decreases, the average upgoing energy flux reduces which implies the ambient winds absorb the energy of the wave, realizes coupling of the different atmosphere layers.

结果表明，当重力波在均匀风场中传播时，非线性效应在顺风场中比在逆风场中更显著，背景风会改变重力波在水平方向的传播速度和传播路径；当重力波在剪切风场中传播时，重力波在垂直方向上平均能流随高度的增高而减少，表明背景吸收了重力波的能量，在重力波向上传播的过程中，实现了大气各层之间的耦合。

In the case of planetary formation, the gravitational interactions between the dust in the disk, the mass in the larger aggregates of material, and the sun itself plus the friction of the material, its thermal properties, and the interaction between the magnetic fields from the star and those of the disk material itself plus countless other factors may be vital in order to understand how planets like our own form from the primordial disk of stardust.

在行星形成的研究中，碟状星尘之间重力的互动、较大聚集物的质量、太阳本身与这些物质间的摩擦、物质间本身的摩擦、物质本身的热力性质、太阳磁力场中这些物质的互动及磁力的影响，加上其他的无数因子都可能是了解地球如何从星尘中诞生的关键。

The flow resistance of Ice slurry increases if the pipes obliquity increases. That means the ice slurry that in the level pipe has the largest flow resistance, the reason is: the gravitation make the flow became more and more foul-up, accordingly, lead to the increase of flow resistance. Sixthly, introduced all of the preparative tasks before we began the experiment, because we met many problems during the test, we had our own methods which could solve these problems. In this paper, problems and these methods were introduced.

随着管道倾角的增大，二元冰的摩擦阻力减小，也就是说相同条件下水平管道内的摩阻最大，这是因为重力的影响导致管道内二元冰和乙二醇分层现象更加明显，从而导致紊流程度增大，最终使得摩阻增大；第六，对二元冰蓄冷空调系统运行前的准备工作进行了介绍，由于在试验过程我们遇到了很多问题，针对这些问题，我们有自己的方法和解决办法，本文介绍了这些问题和相应的解决办法。

The OH airglow volume emission rate has an obvious response to the breaking gravity wave and atomic oxygen.

在重力波的传播过程中，氢氧大气成分的水平和垂直分布均受到了不同程度的影响，以氧原子的响应最为明显，而其中重力波破碎在氧原子水平分布上的反应则是非线性重力波过程的一个重要表现；另外，分析显示，重力波的非线性传播对OH气辉的峰值分布由明显影响，小尺度重力波的传播有时会引起OH气辉出现奇异的双峰分布，重力波的破碎现象也可以从对气辉的观测中反映应出来，这对利用气辉观测研究重力波传播特性有非常重要的指示意义。

The breaking of gravity wave accelerates the downward transport of atomic oxygen, some smaller-scale structures appear on the horizontal distribution of atomic oxygen number density , and other chemical species are also affected due to the chemical reaction with atomic oxygen and the propagation of gravity wave. The OH airglow volume emission rate has an obvious response to the breaking gravity wave and atomic oxygen. The nonlinear propagation of smaller vertical wavelength gravity waves can induce the double-peaked structure in the OH airglow. The results can explanation some sporadic measurements of OH airglow and can provide a good indication for studying the characteristic of nonlinear gravity wave by using OH airglow measurement.
