These work are mainly based on two assumptions: one is called as the Deeg-Pak assumption, i.e., the crack is assumed to be an impermeable slit and thus the electric field inside the crack is equal to be zero; the other is called as the Parton assumption, i.e., a crack is treated as a permeable cut across that both the normal components of electric displacement and the tangential component of electric field are continuous.

裂纹问题：对于压电介质内的裂纹问题，近十年来人们已做了大量的理论分析工作，这些工作主要是基于两种假设：一种称之为 Deeg-Pak 假设，即假设裂纹为电非渗透的，因此裂纹内的电场等于零；另一种称之为 Parton 假设，即假设裂纹为电渗透的，且跨越裂纹上下表面电位移的法向分量和电场的切向分量是连续的。

One obvious problem is that when one party is the transgressor, that party is obviously going to be reluctant to submit the dispute to the court.

一个非常明显的问题就是，当一个当事国是违法者，哪个当事国就非常可能不情愿的在国际法院上被起诉，如果法院被要求做出一个有拘束力的司法建议，这些建议的效力就可能等于零。

:at any point of elastic object ,the rotating value of z axis is :ν u θz = substitute get:ν= u = y x θz = 0 x y into the formula , we can Similarly:θx = 0 θy = 0 So the rotating values of the three coordinates at any point of the elastic object are zero.

：在弹性体的任一点处，该点对z 轴的旋转量ν u θz = x y u =ν=将代入，可得： y x θz = 0 同理θx = 0 θy = 0 即弹性体的任一点对三个坐标的旋转量都等于零。

Statics 静力学 A workpiece lies on a drill press, four equidimensional holes are drilled in the work piece, the force couple of every drill is .

Statics 静力学平面力偶系平衡的充要条件是：所有各力偶矩的代数和等于零。

Elasticity of production with respect to labor input would be very low or even nul on the starting point of development and should be around 0.75 in the neoclassical world, meaning it must increase in the development process.

劳动产量弹性在发展起点上很低甚至等于零，但在新古典经济中是个0.75左右的真分数，所以，劳动产量弹性在经济发展过程中将上升。

But, in 1934, Karl Popper, one of the most influential philosophers of our time, argued that the mathematical probability of all theories, scientific or pseudoscientific, given any amount of evidence is zero.

但是，当代最有影响的哲学家之一卡尔。波普尔于1934年论证到，在任何特定数量的证据下，所有理论，无论是科学的理论还是伪科学的理论，其数学概率都等于零。
