3.Using the boundary integral equation solutions given by the present author about the Griffith crack problems, the plane problems of collinear cracks between the joined interface of half planes with different elastic properties are investigated. The boundary integral equations and stress intensity factors involving dislocation densities are derived. And the generally analytic solutions are obtained.
本文利用作者关于Griffith裂纹问题边界积分方程法的已有结果,研究了两种不同弹性半平面材料粘接界面的共线裂纹问题,导出了问题的边界积分方程和应力强度因子的位错密度公式,获得了问题的一般解析解。收藏指正
4.The paper deals with the constructing a Green function, by means of the second category zero-order imaginary variation Bessel function K_0(x), of the Helmholtz equation △u-q~2=0 in a half plane, one fourth plane, any angle area and belt-shaped area. Thus an exact integral solution expression of equation is given.

5.The paddy seeds were often broken or even damaged, and its germination rate or integral rice rate was reduced by the method of traditional half-feeding thresher, because it often impacts and sorts out paddy rice by wire-loop, rigid spike-tooth or rigid pole tooth.
摘要传统的水稻脱粒系统通过刚性弓齿、钉齿和杆齿对水稻进行打击脱粒,造成水稻籽粒破碎或者籽粒内部损伤,降低了种子发芽率和大米加工的成米率。收藏指正
