	9.	From this basic thought we can see , because of the square number of now time news voice is the limited item square number to returned to return in the past , it ’ s means that the motion of the news voice have the certain memory , therefore , if in past every moment the square number of the news voice differed to become big , so the square number of the news voice differed to usually also come after it to 从这个基本思想中可以看出,由于现在时刻噪声的方差是过去有限项噪声值平方的回归,也就是说噪声的波动具有一定的记忆性,因此,如果在以前时刻噪声的方差变大,那么在此刻噪声的方差往往也跟着变大;如果在以前时刻噪声的方差变小,那么在此刻噪声的方差往往也跟着变小。
	10.	The apsp produced abroad is made by numerical controlled machine tool , which has noise level of 71db ( a ) , the apsp produced in our country is made in the method of exploratory which has noise level of 73db ( a ) and 75db ( a ) . in order to analyze the influence of stator curve to noise , the author used tri - coordinate measuring instrument to measured exactly the inside surface of stator and got the straddling point coordinate , and made curve fitting by using matlab as language and studied the fitting effect and then worked out the equation of stator transition curve in return seeking , then comparied this method with the standard style and made the conclusion : the equation of atator transiting curve of apsp made by numerical controlled machine tool is close to theorical 5 power curve standard style , but compared with it , the stator transiting curve of apsp produced in exploratory has a major error . combining the testing results of noise , one can know that the qualily of stator transition curve play an importance to t he noise of the pump 国外生产的汽车动力转向泵是用数控机床加工的，其噪声值为71db ( a ) ，国内生产的汽车动力转向泵是用靠模方法加工的，其噪声值分别为73db ( a )和75db ( a ) ，为了分析定子曲线对泵的噪声的影响，本人用三坐标测量仪对定子内表面进行精密测量，获得定子内表面的离散点坐标，以matlab语言为工具对离散点进行曲线拟合，观察拟合效果，然后，用回归方法求出了定子过渡曲线的方程，并把该方程与理论方程标准型进行了比较，得出如下结论：用数控机床生产的汽车动力转向泵的定子过渡曲线方程非常接近理论5次曲线标准型，而用靠模方法加工的汽车动力转向泵的定子过渡曲线与理论5次曲线标准型相比较，则存在着较大的误差，结合噪声测试结果可知，定子过渡曲线的优劣，对泵的噪声大小有着重要的影响。
