Next the discussion in this study, about an ellipse with an angle of attack and two circular cylinders with different diameters in the flow, the aim of this study is investigated for the ability of the present numerical method by solving the suppression of the vortex shedding flow behind the two-cylinder system which was kind of difficult to reach by a Cartesian grid method. In this study, the suppression of the vortex shedding flow is tested to solve a uniform flow past through two different diameter cylindrical in the flow field with Fractional Step Method and Immersed Boundary Method.The numerical method which we investigated is showed that the results of the problem is appropriable in other literatures.

接著探讨流过具攻角之椭圆柱体流场及流过圆柱抑制涡漩逸出之流场，目的是要研究利用控制圆柱来抑制下游涡流的流场行为，本文采用分步法配合内嵌边界法数值解析一均匀流流经两不同直径的圆柱流场，来测试抑制涡流逸出的问题，根据现有的数值结果发现试验运用了合适的方法且得到令人满意的结果。

Compared with the straight and helical gear, the contact and bending intensity of the symmetry arcate tooth trace cylindrical gear are high.

分析结果表明，对称弧形齿线圆柱齿轮的接触和弯曲强度均比直齿和斜齿圆柱齿轮好。

The contact tooth surface of the cylindrical gear with symmetrical arcuate tooth trace is analyzed with this method, and the results are compared with those got with the traditional TCA method.

用此法对弧形齿线圆柱齿轮进行了实例分析，分析结果表明此方法是正确可行的。

It is shown that the symmetric arcuate tooth trace cylindrical gear is a type of highly durable and heavy-load gear.

对称弧线圆柱齿轮作为一种高性能重载齿轮，适用于石油、矿山等重型机械，也能够满足各种机械对齿轮高精度、低噪音以及结构紧凑的要求。

Miscamthus floridulus, Arundo donaxl, Artemisia argyi, Comnyza Canadensis, Crotalaris mucronata, and Kummerowia striata, are pioneer plants for vegetation recovery in coal piles. They have high summed dominance ratio and take crucial action on vegetation recovery and community succession. Many pioneer plants including annual and perennial herbs, e.g. Imperata cylindrical, Comnyza Canadensis, and Crotalaris mucronata colonize successfully to provide conditions for colonization of shrubs, e.g. Buddleja asiatica.

耐贫瘠、广布性植物如五节芒、荻芦竹、艾蒿、小飞蓬及豆科杂草猪屎豆、鸡眼草等是煤矸石堆植被恢复重建的先锋植物，它们在群落中综合优势比较大，对植被重建和群落演替起决定性作用；许多一年或多年生草本植物，如白茅、小飞蓬、猪屎豆等先锋植物的成功定居，为驳骨丹等灌木的入侵创造了条件。
