From the theoretical point of view , the problems of obturation , partiality in regulation implementation , and unilateralization in role playing are existing in the motivation mechanism 从理论的层面来讲，当前高校的学生激励机制的则存在着封闭性、原则贯彻之中的偏颇性和角色定位之中的单向性等问题。

Moreover , the inner personnel , the material conditions , the relative obturation in country area , the indulging in bottom administration and connivance of parts of cadres all cause the revival of clan force 此外，宗族势力的复活还有其内部人员条件，基础物质条件，乡村社会的相对封闭性及基层行政机关的放任自流和个别党员干部的纵容、包庇等。

Although the lead - acid battery has many shortages , at present , it still is the main energy to electric vehicles for low price and maturate technics , in particular , the technology of obturation have been perfected 铅酸蓄电池作为电动车电源，虽尚有许多不足，但由于其价格低廉，工艺成熟，特别是近年来密闭技术已日趋完善，所以铅酸蓄电池在动力电源中仍占有一席之地。

In this way , when obturation cubage leave absorb oil cavity it connects the eduction oil cavity with the v trough and with the increasing of the turning angle , the size of the cross section of v trough become bigger and bigger , which make the pressure between the cavity of two blades much higher and higher , and until it completely connects the eduction oil cavity , it reaches the pressure of the eduction , and it can effectively reduces the fluid noise caused by high pressure return flow 这样，当密闭容积离开吸油窗口之后，通过v型尖槽逐渐与排油窗口连通，随着转角的增加， v型尖槽通流截面积逐渐增大，这就使两叶片间容腔内的压力逐渐升高，直至完全接通排油窗口时，才升压达到压油腔的压力，这样可以有效地降低因高压回流而引起的流体噪声。

Fluid noise mainly comes from out put pulsation of rate of flow , the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition . the v trough on the port plate can reduce the fluid noise . in this paper , the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12 . 3 and its length was 5mm and the cross section was an equilateral triangle 流体噪声主要来源于输出流量脉动，造成输出流量脉动的主要原因是闭死容积在大圆弧段压力切换时产生的瞬时高压回流，在配流盘上开设v型尖槽可降低因高压回流而引起的流体噪声，本文以截流作用和液体的可压缩性为理论依据，以matlab语言为工具，对原配流盘上的v型尖槽进行了理论计算，绘制出p - t图线，分析了它的不足，并对原有v型尖槽进行了优化设计，得出了v型尖槽的最佳几何尺寸：配流盘平面上的v型尖槽的两边的夹角为12 . 3 ，槽长5mm ，槽的横截面为等边三角形。
