本文分别对钢板弹簧和空气悬架两种悬架的整车行驶平顺性进行仿真分析与评价，结果表明空气悬架的整车行驶平顺性要优于钢板弹簧悬架，证明在该运油车上匹配空气悬架是可行并且有意义的。

According to the air trajectory of every rocket-assisted torpedo part, we establish an equation group of air vertical motion, improve the in-air trajectory model, and simulatively calculate the polynomials of firing distance and flight time,and firing distance and shut down time. Making use of the polynomials, we calculate the cooperative time of formation salvo of torpedoes, and determine command ways for different situations. The result may facilitate the research of operational application of rocket-assisted torpedo.

This essay will remark on auto air-condition noise problems through studying expansion valve. The main reasons incurred noise are two, one is vibration, which is from big air bubble caused by the refrigerant flows through expansion valve. Another is resonance, which is from engineering working itself. So, the two methods for eliminating noise are found. On one hand, through increasing damp to weaken resonance. On another hand, through taking off air bubble to eliminate vibration. The essay presents method of solving noise through improving expansion valve and elaborate the disadvantages caused by these solvement.

本文从膨胀阀的角度去考虑解决汽车空调异响问题，认为产生异响的主要原因是制冷剂流经膨胀阀节流部时有大气泡存在引起振动与汽车发动机共振造成，从增加阻尼块来减振和分解大气泡来消除震动等两方面提出解决方法，并对此方法造成的不利方面也进行了阐述。
