There is, of course, no shortage of historic grand jewellery gestures: Queen Victoria chose a coiling snake ring for her engagement to Albert, while the Duke of Windsor gave Wallis Simpson a huge 19-carat emerald ring inscribed with 'We are ours now' and dated 1936 – the year Wallis's divorce came through.

自然，具有历史意义的珠宝也不在少数：维多利亚女王为她与阿尔伯特的婚约选择了一款卷曲蛇型的戒指，温莎公爵送给华丽斯·辛普森一枚镶有19克拉翡翠的戒指，上面刻着&现在我们属于彼此&，日期为1936年，正是华丽斯离婚的那一年。

In the joint of LG PEX-A Pipe ,male xocket is pressed to a convex on the inserting part and the fastening ring will contract to fasten up the heating pipe by the fastening of outer nut,and there is also a convex on the ring to offer close coupling by mechanical re-press effect to prevent water from leaking in case of heat expansion.

在LG地热管中的连接部位不仅阀门管套插入部分的凸起部位被机械作用压密，而且随着外部螺母被拧紧，使紧固环收缩，从而带紧热炕暖气管，另外由于存在凸起部位，可通过机械作用进行再次压密，因此可防止由于热膨胀而引起漏水。

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。
