Designing space mechanism run into question at first is that correct to confirm space degree of freedom of organization, but calculating many degrees of freedom, seal more ring, harmony wave gear wheel organization, space degree of freedom of organization of mixing with traditional degree of freedom must be very tedious; Calculating general form seal ring low packs of space degree of freedom of organization can be limited greatly too.

设计空间机构时，首先遇到的问题是要正确确定空间机构的自由度，然而，用传统空间机构自由度公式去计算多自由度、多封闭环、谐波齿轮机构、混合型空间机构的自由度时，必须进行变换；计算一般单封闭环低副空间机构自由度时，也会受到很大限制。

The author established the axisymmetrical bubble with the vortex sheet and the vortex ring and established the three-dimension bubble with vortex ring respectively based on the achievements of the former researchers.

本文在总结前人研究成果的基础上，分别建立了轴对称涡面模型、涡环模型以及三维涡环模型。

The numerical results were in good agreement with the measured results. The experimental and numerical results show that the vortex ring was induced by baroclinic effect and Helmholtz instability in the vicinity of the thruster exit after the donation wave exhausted the tube. The intensity, shape and location of the suspended shock varied when the shape of the vortex ring changed.

爆轰波溢出爆轰管后，斜压效应和Helmholtz不稳定导致涡环的产生，同时在流场中形成止于涡环的悬吊激波，涡环形状的变化又引起悬吊激波的强度、形状和位置的变化。

The analysis shows that with given grid size higher accurate difference scheme can give higher resolutions with wider range of scales, or with given accuracy large grid size can be used for the higher accurate difference scheme. The second part is the numerical simulation of two-dimensional axisymmetric jet. The simulation results show the structure in the near field and the initial transition. In the near field, Kelvin-Helmholtz instability leads to the formation of vortex ring, and nonlinear growth leads to the merging of vortex ring. This is the main instability form. Under the assumption of axisymmetry and two-dimensional computing conditions, the results are applicable only in the near field.

第二部分采用高精度的差分格式对二维轴对称射流进行了数值模拟，模拟结果显示了射流流场结构和涡结构的发展过程，在射流流场近区，K-H失稳导致涡环的产生以及非线性效应的增长导致涡环的对并是射流失稳的主要形式；分析指出在轴对称假设下的射流数值模拟只适用于射流近区的分析。

The model of 3-dimensional stretching vortex ring of turbulent elliptic jet in crossflow are discovered for the first time. It is pointed out that in the evolution of turbulent jet in crossflow the 3D vortex rings, which stretching, distorting, swing in transverse direction and twisting around the stream-wise, play the leading role in the large-scale coherent structures. The counter-rotating vortex pair observed in the literature is in fact the head of the 3-dimensional vortex ring.

首次发现和提出了湍流横向椭圆射流的三维拉伸涡环模型，指出在其大尺度拟序结构中真正占主导作用的是拉伸、扭曲、沿流向扭动、展向摆动和绕x轴的转动的三维涡环，在众多实验和文献中观察到的反向涡对其实是由三维涡环头部组成。

When the pump to work, you can cut off the water through the valve and pump impeller ring round access, and release the water within the liquid ring round.

当泵正常工作后，可通过阀截断水环轮和水泵叶轮的通道，并且放掉水环轮内的液体。

Exchange the sealing ring of the valve body according to the working condition of rubber sealing ring in order to ensure the sealing performance.

按橡胶密封圈使用性能，根据具体情况定期对阀体的密封圈进行更换，以保证阀门的密封性能。

The valve seat ring - welded seat ring is perpendicular to flow path, easy to maintain.

4阀座环–焊接阀座环垂直于流动通道，易于维护。

When the pump to work, you can cut off the water through the valve and pump impeller ring round access, and release the water within the liquid ring round.

当泵正常事情后，可通过阀截断水环轮和水泵叶轮的通道，并且放掉水环轮内的液体。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
