Basic characteristics of cosine transform spectrum were analyzed, where contour lines of 2D cosine transform of point mass present the shape of a quarter of concentric circles and the number of counter become small along with the increasing of wave numbers. The spectrum of vertical rectangularcylinder put up periodic zero counters which mark off quadrate areas, the values of counter in each areas alternately change between the plus and the minus, and with the increasing of wave number, the values of counter present attenuation character alike e exponent.

分析了点质量和直立矩形柱体重力异常余弦变换谱的基本特征：点质量二维余弦变换谱等值线呈1/4同心圆形状，等值线随着波数的增大而变稀；直立矩形柱体谱出现了周期性变化的零等值线，该等值线将非零等值线划分为a×b个矩形区域，而且等值线值在各矩形型区域中正负交替变化，随着波数的增大，不同的矩型域中等值线值呈e指数衰减特征。

The math model of the movement,flux and control system of position pump was established by analyzing its working principle,and its hydraulic system simulation model was established based on AMESim.The pressure and flux pulsation of the position pump was analyzed,and the pressure and flux was calculated by simulation when there are sign of wear for the position pump and system flux change.
