The method divides block along the intersection edge of joint faces and neglects the vertical shear force between dividing-blocks i.e. takes horizontal normal force and shear force into account; as to an assumed sliding direction, by satisfying vertical force equilibrium of every dividing-block and whole force equilibrium in the sliding direction, the factor of stability can be solved.

基于此，提出分块极限平衡分析法，该方法沿非临空面交棱将块体进行分块，在忽略分块间的垂向剪力（即可考虑分块间的水平法向力和剪切力）前提下，通过满足各分块的垂向力平衡和滑动方向上的总体力平衡，求解特定滑动方向的稳定系数。

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.

此外，本文还研究了圆锥形件拉深成形过程中，随着拉深变形过程的进行，毛坯为避免产生起皱、破坏缺陷而对压边力的需求情况，阐明了圆锥形件拉深成形过程中压边力合理变化的必要性；由毛坯主要变形区悬空锥壁部分的受力变形情况，从力学分析的角度，首次推导得出了圆锥形零件悬空锥壁起皱失稳的临界条件；并根据主要变形区法兰、悬空锥壁及凸模圆角部分的塑性失稳临界条件，在其成形范围图中，将圆锥形件成形过程中的压边力划分为四个区域；总结并提出了圆锥形件成形过程中压边力合理变化的基本原则；建立了防止起皱、破坏缺陷产生的压边力合理变化的数学模式，并得到了有限元数值模拟及网格实验法的验证，证实了理论分析结果的正确性和可靠性。

The outside nature -- the natural environment or Nature herself -- is shown as some mysterious supernatural force, very powerful but half-blind, impulsive and uncaring to the individual's will, hope, passion or suffering.

外界自然--大自然的自然环境或自己--表现为一些超自然的神秘力量，很强大，但半盲、冲动、缺乏爱心的个人的意志，希望受难或痛苦。

His art represents another style of surrealism, which is organic surrealism. He tries to destroy the control of ration and logic, liberates unconsciousness and impulsive force of illogic mind, as well as to explore the secrets of the invisible realms and the visual world.

他的艺术代表了超现实主义的另一种风格，即有机的超现实主义，他企图要毁面理性和逻辑的主宰，把无意识和非逻辑心灵的冲力从中解放出来，且探测不可见领域和视觉世界的奥秘。

In combination with sensitivity analysis, it is found that the main reason causing the fuse failure in bore is the lateral shock between the bourrelet and the bore surface. This shock produce huge lateral impulsive force and acceleration causing fuse mechanism plastic deformation and improper function. Besides, it may lead to fall-off in fuse safety.

造成引信瞎火的主要原因是由于弹丸在膛内运动期间，弹丸与身管内壁间的相互碰撞所产生的横向冲击加速度使引信保险机构产生多次重复振荡，使其产生局部塑性变形及破坏不能可靠解除保险所致；并可能导致引信膛内安全性下降。

This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.

本文研究了径向潮流冲量矩M与阿莱现象的关系，得出的结论是：M作用于地轴激发了Chandler摆动；M的变化取决于海水、引潮力和地球自转效应的相互作用；日食或月食期间，在一定的条件下，M变化的非常剧烈，引起Chandler摆动振幅脉冲式的变化，进而引起地球纬度的变化，最终导致地球表面重力加速度的变化；这种变化可以通过傅科摆摆动平面角速度的变化或重力计的示数变化反映出来。
