轴向对称流动

It is governed by the equation of continuity and momentum for the liquid in cylindrical coordinates with axial symmetry, the isentropic equation of state for water.

曲面头部的水弹高速冲击刚性表面的流体动力学问题，可以归结为无粘性、可压缩的不定常流动问题，受轴向对称园柱座标的连续和动量方程、水的等熵状态方程支配。

It is revealed that the asymmetric vortices over slender body are formed the breakaways of higher position vortex and generation of new vortex, which are alternately developed on the both sides along the body axis. The correlation between asymmetric vortices structure and distribution of sectional sideforce coefficient has been obtained. A physical model of asymmetric multi-vortices flow structure is developed according to zonal flow analysis.

在此基础上揭示了非对称涡系是通过细长体两侧背涡沿轴向交替脱落、新生而形成的，给出了非对称涡系沿轴向演化、发展的流动结构和截面侧向力分布特性之间的相关关系，在分区分析的基础上提出了非对称涡系结构的物理模型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
