From both the theory analysis and the experiment results, all the factors that can affect the static and dynamic properties of the value system including the unidirection transient flow sensor are discussed. A lots of experiment results show that the value performence is excellent.

在第二章，作者在理论和实验上得到影响和提高包括单向动态流量传感器在内的流量电反馈电液比例二通阀稳、动态特性的各方面因素，大量实验结果显示出该阀优良的性能。

The research contents of this subject are mainly: Proposing the overall scheme of the soft firing technology, than confirm the best scheme; On the basis of best scheme , set up the mathematical model of soft firing system, and set up the interior ballistic trajectory calculating model among MATLAB/Simulink, set up soft the three-dimensional dynamics model of firing system among ADAMS; Go on joint simulation, simulating the characteristic curve of bore pressure and the sport law of piston and shot; Through adjusting the parameters such as piston quality、the diameter of unilateral valve、 charge weight、charge form coefficient and the delay time of lighting fire etc to make the soft firing system reach the best state of dropping the composition of forces of gun bore and increasing initial velocity of pill.

论文的研究内容主要是：提出软发射技术总体方案，确定最佳方案；在最佳方案的基础上，建立起软发射系统的数学模型，并在MATLAB/Simulink中建立内弹道计算仿真模型，在ADAMS中建立软发射系统的三维动力学模型；进行联合仿真，模拟膛压特征曲线及活塞和弹丸运动规律；通过对活塞质量、单向阀直径、装药量、药形系数、点火延迟时间等参数进行调整，使软发射系统达到炮膛合力下降、弹丸初速提高的最佳状态。

Special emphasis should be put on the parallel connection of Venturi mixer, for it can avoid the stalling disadvantage of series-wound connection of Venturi mixer, enlarge the modulating range of EGR rate enormously, and make the best of Venturi mixer.

在前文建立的性能与排放综合预测模型基础上，增加简化的EGR管路流动模型，首次将排放预测与实时EGR管路流动结合起来，进行单向阀EGR系统的性能与排放综合预测。

Also, because oil-absorbing tube 6 in the role of one-way valve 7, compressed air will not flow backward into the oil pipe from the oil-absorbing cup, so we can keep gas in a state of the oil gagged refueling, refueling is completed, screw plug oiling .

又由于吸油管6中单向阀7的作用，压缩空气也不会从吸油管倒灌到油杯中，所以就可以在不停气的状态下向油塞口加油，加油完毕，拧上油塞。
