half-integral
1.A particle, such as an electron, a proton, or a neutron, having half-integral spin and obeying
2.A particle, such as an electron, a proton, or a neutron, having half-integral spin and obeying statistical rules requiring that not more than one in a set of identical particles may occupy a particular quantum state.
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.
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.
