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。
