For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

在圆柱流场时，我们探讨不同马赫数且不同纽森数时的流场特性，并在低纽森数时，与那维尔-史托克方程式的计算结果比较，我们比较了弓形震波及尾流附近的特性，其结果是相当符合的，同时我们也比较不同高解析隐式算则的收敛历程，从收敛历程图可得到，本文发展出来的隐式WENO算则有较佳的收敛效果；在NACA 0012翼形的流场中，我们将与实验结果做比较，发现利用WENO算则计算的结果，对於具有攻角的流场，亦有相当高的准确度。

For satisfying to process to keep a mother line, arc mother line, whole convex degree, half convex degree, ligarithmic curve cone, cylinder roll son of demand, ability according to design whet to submit have already corresponded form noodles of spiral lead a round, spiral lead Gun, double the song lead Gun, three convex Fengs to lead Gun, and arc plank and other similar of work piece etc..

In this paper, we use the Pluricomplex Green function to investigate the iterative poperties of holomorphic self-maps, which are defined on the unit disk, the unit ball, the bounded strongly convex domain and the bidisc.

基于该思路，本文就利用多复Green函数，在分别研究了单位圆、超球、有界强凸域以及双圆柱上全纯自映射迭代的基础上，进一步研究了一特殊非凸域-Hartogs三角形上全纯自映射迭代的性质。

Some players believe that "corking" a bat (hollowing out a cylinder in the head of the bat and filling it with cork or rubber, then replacing a wood cap) enhances the "sweet spot" effect.

一些球员认为，给球棒"软木化"（在球棒头部掏出一个圆柱空腔，在里面塞入软木或橡胶，然后盖上木帽）能够增加"最佳点"的效果。

To satisfy the requirements of fast producing,low cost manufacture and large thickness preforming in the field of non-resin winding cylinder composite,the equation of retracing cosine curve was deduced based on the section principle.

最后基于对余弦折回曲线的分析，利用数值模拟证实余弦折回曲线在干纱缠绕圆柱壳体预成型中有利于高速加工；在缠绕厚度相对不大且需要高速缠绕加工情况下，可采用余弦曲线作为端部区段的折回曲线。
