In addition, some occupations such as a policeman, firefighter or steelworker are naturally more dangerous than others, leading to a possibly reduced life span.

除此之外，诸如***、消防员以及钢铁工人这些职业，自然要比其他类别的职业更加危险，从而导致一个人的寿命可能缩短。

Based on wind tunnel tests, this paper deals with the ability and causes of maneuvering flaps to decrease drags, the effects of the flap span , the flap chord, the strake and the wing plane form on the aerodynamic characteristics of the maneuvering flap, the matching of leading-edge and tailing-edge flaps, the improvement in the large angle-of-attack flying quality.

本文根据风洞实验结果，讨论了机动襟翼减阻的能力和原因，襟翼弦长和展长的影响，前缘襟翼和后缘襟翼的配合使用问题，机翼边条和机翼平面形状对机动襟翼减阻的影响，以及机动襟翼对大迎角飞行品质的改善情况。

A Material nonlinear finite element analysis for the cast-in-place reinforced concrete hollow slab that occurs from initial loading, cracking, yielding to failing is carried on. The cracking load, ultimate load, the displacement rules and the principal stress distribution rules of the hollow slab under the vertical loads are obtained. A Material nonlinear finite element analysis for the single span hollow flat-plate floor is also carried on. The function of the concealed wide-flat beams is definite by analyzing the principal stress distribution diagram. The calculating results verify the theoretical analysis and give some important conclusions which are great useful to improve the constructing of the new flat-plate floor.

其次对空心板进行了从加荷、开裂、屈服直至破坏的全过程材料非线性有限元计算，得到了空心板在竖向荷载作用下的开裂荷载、极限荷载及位移和应力分布规律；还对单跨无梁楼盖进行了材料非线性有限元计算，通过分析主应力场明确了柱上暗扁梁的作用；有限元计算的结果验证了以上的理论分析并得到了一些重要的结论，对改进现浇空心板无梁楼盖的构造措施有重要的参考价值。

Researchment on Cable Dome begin with the Concept Design, which including geometric stability, ratio of rise to span, space between struts, height of struts, space between strop, inclination between ridge cable, etc.

对索穹顶结构设计技术的研究首先从概念设计开始，概念设计包括结构的几何稳定性判断、跨度和矢高的关系、压杆的间距、压杆的高度、环索的间距、脊索间夹角等，后面几个部分其实也可以归结为结构几何参数的优化问题。
