By analysising the datum in different prestressing force of piston spring shows that raising the prestressing force of piston spring only have a small influence on stroke time to keep the other paramters in costant, but the back stroke time will be decreased and the frequency, the percussive energy and the hydraulic efficiency will be increased rapidly.

对不同锤簧予压力下液动冲击器性能变化的试验数据处理、分析得出：在保持液动冲击器的其它参数一定时，增加锤簧予压力对冲程时间影响不大，但可以大大缩短返程时间，大幅度提高冲击频率、冲击功和液动冲击器的水力利用效率，增加锤簧的予压力是提高液动冲击器性能的一种有效手段。

Based on the 3D solid model, the changing trend of spiral angle and pressure angle of pitch cone, the thickness-changing trend of face and pitch cone can be analyzed. In addition, the method of cutting tooth on general NC machining center and the measurement of tooth flank geometry on 3D CMM are conducted.

The projectile velocities of the model experiments and the prototype experiments are not proximal, so a grey pre-estimation model of maximum penetration depth is established.

由於模型试验的弹速不够接近原型试验的弹速，在模型试验数据处理中引入了灰色系统理论，建立了最大侵彻深度灰色预估模型。

Then, taking this result as the pre-experiment knowledge to eliminate these bad influence in the behind process of weighing data treating. Moreover, these factors should be also fully considered in the software and hardware design, and these bad influence should be fall to the lowest level.

然后以此作为先验知识并在以后的称重数据处理过程中来重点消除这些不良的影响，而且在软硬件的设计中也要充分考虑这些因素，将由汽车的振动产生的对系统的不良影响降到最低水平。

Finally, lots of experiments are made and the results indicate that automatic recognition of the gauge is reliable to recognise gauge value and has the certain application value.Automatic recognition of the gauge by the machine vision technology not only reduces the intesity of labor but also increases the precision of reading gauge. The application of machine vision technology promotes level in the precision measurement.
