Order determination is accomplished in two stages, i.e., the AR order is first determined by the minimum eigenvalue of overdetermined instrumental variable product moment and the MA order is then estimated by the minimum eigenvalues of a covariance matrix derived from the observed data.

该方法将ARMA模型的结构辨识分两步进行：首先利用超定辅助变量乘积矩(0IVPM)的最小特征值确定自回归部分的阶，然后利用协方差矩阵的特征值估计滑动平均部分的阶。

On the base of probabilistic and statistics results of joints and cracks, the Author modifies Block Theory. The sliding probability of Key Block is I A RSTR A CT F2 ? 5.It is put up forward that GM(l,1) Model to predict Amount of rainfall, and Markov Chain to modifY GM( 1,1 )predicting result, and then a theoretical predicting Model of amount of rainfall is firstly built. This model is applied in a situ example. It is proved that the model is very useful to predict amount of rainfall ,when ordinal array of Amount of rainfall changes in unexact index rule.

WC particles also can make the abrasive particles obtuse ,consequently reduce the cutting of abrasive particles to the coating.(7) The coating surface with unsmoothed units make the abrasive particles change moving direction . They can change the ploughing to rolling and bring light longitudinal vibration contributing to reducing the shearing force when the surface are worn by abrasive particles.

具有非光滑结构单元的复合层表面使参与复合材料磨损的磨粒改变运动方向，使之由滑动变为滚动，产生有利于减小切向力的法向微振动，减少磨粒和复合材料的接触面积和作用时间，从而大大减轻了磨粒对复合材料表面的损伤。
