By the principle of penalt function, the irrotational fluid field is constrained, and author has proposed the Difference Method for distinguishing fluid vortex modes among the natural modes of coupled systems. Author has calculated the real frequencies with the extra deductive method, and discussed the influence of the numerical solution due to the irrotational constraint.

对于流体有限扰动时的非线性耦合系统的有限元分析作了一些探讨，给出了非线性系统的基本方程、变分原理及有限元方程，并具体地导出了三维几何非线性流体单元的切线刚度公式，采用增量形式的Newmark预报——校正逐步积分法计算系统的动力响应，由Newton-Raphson迭代法及其修正方法求解系统的非线性方程组，还列出了不平衡力余量检查和位移迭代增量检查等迭代收敛判断准则。

Aimed at load-carrying mechanism, systematic study was made on the functions of basic topological structures and some functional structures of the cylinder head, such as sprayer jacket, ports, strengthen rib, jobbing sheet, etc., in the load carrying system. Moreover, the deformation characters of these structures in the processes of carrying and transmitting loads were also thoroughly studied by the thesis.

针对气缸盖承载机理，系统地研究了气缸盖中的基本拓扑结构和气缸盖中一些功能结构——喷油器护套、气道、气门导管座孔、中隔板和加强筋等结构在气缸盖承力体系中的作用，以及这些结构在承受和传递载荷过程中的变形特性。

Classical mechanics, but Galileo, the creator of "the embryo form of law of inertia",with the incline experiment only attested to the falsity of Aristotle's proposition that "the force is the indispensable factor to maintain object movement", and not proposed what is the indispensable factor to maintain object movement.

牛顿第一定律被认为是经典力学的最基本定律之一，但"惯性定律雏型"的原创者伽利略用斜面实验只证伪亚里士多德的"力是维持物体运动不可缺少的因素"这一命题，并没有提出什么才是维持物体运动不可缺少的因素。
