Thirdly, on the base of the existent error estimate of elliptical Galerkin projection operator, obtain semi-discrete and complete-discrete error estimates betwent EFG solution and exact solution of parabolic partial differential equation. Semi-discrete error estimate show that the rank of r is accordance with the approximation rank of subspace S_h. Complete-discrete error estimates show that it not only have relation with radius r of domain of influence, but also have relation with the step length of time variable and the way of discrete.Lastly, give typical examples and draw up procedures of MATLAB.

We gain the distributing instance as a whole by the spatial analyse of the daily、 mensal and annual precipitation.Then, we adopt mean error、 mean absolute error、 mean relative error、 and the root mean squared interpolation error and the correlative coefficient as the determinant standard of interpolation effect. The results show that the mensal precipitation effect of SIA is the best, and the daily precipitation effect is worse reversely.

The author made an analysis of the ratchet gearing used let-off mechanism in the K251 type loom and of the effect to loomage, and came to the conclusion that is: 1. The long length of the loom cause bigger LO, which reduce weaving defects caused by let-off error. 2. At the same status of the loom, the possibility of appearing weaving defects is relative to the characteristic of the loomage, namely, if the stiffness coefficient of the loomage and organzine has lesser difference, the possibility of appearing weaving defects will be lesser, contrarily will bebiggish. 3. The displacement error AL affects the value of the weavingdefects directly, besides wind error, it is a effective method to reduce let-off error.

通过对K251丝织机棘轮送经机构及其对织物影响的分析，得出以下结论：1、丝织机的长机身使Lo较大，有效地降低了由送经误差造成档疵的可能。2、在织机状况相同的情况下，档疵出现的可能性与织物的特性有关，即织物与经丝的刚性系数相差较小的，档疵出现的可能较小，反之较大。3、织口位移误差△L，对档疵有着直接的关系，除了卷取误差，减少送经误差是减少档疵出现的有效的方法。
