The paper consists of three parts. First, we give the calculation for every order central moment for the Logistic population, mean vector and covariance matrix of the order statistic of random sample from the Logistic population, and means of several special functions for the order statistic of random sample from the Logistic population. Secondly, we discuss the parameter estimation for the Logistic population. Finally, we solve the question about the goodness-of -fit test for the Logistic population.

Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.

The results show that when the porosity of sample was higher, compressure rate was higher and resilience rate was lower, however resilient rate of sample with higher porosity were increased notably when pressure was increased, and it tended to accord with of sample with lower porosity. The friction coefficient was higher when porosity of paper-based friction material was higher, and the friction coefficient tended to reduce and stabilize when braking pressure was increased. The friction coefficient of sample with high porosity tended to reduce and stabilize in continuous braking cycles.
结果表明:在相同载荷下,随着孔隙率增大,材料的压缩率增加而回弹率降低,随着载荷增加,高孔隙率材料的回弹率先明显增大,而后趋于稳定;在相同比压和转速下,孔隙率越高,材料的摩擦系数越大,随着比压增加,孔隙率高的材料摩擦系数逐渐降低,且不同孔隙率材料的摩擦系数逐渐趋于一致;在连续循环制动时,高孔隙率材料的摩擦系数逐渐降低并趋于稳定。
