The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.

在对蓝移理论的研究中，本文发现了一类质子给予体不能进行重杂化的氢键蓝移体系，说明了&超共轭—重杂化&理论的不完善；而将Pauli／nuclei排斥理论应用到本文新发现的两类蓝移体系——锂键体系和双氢键体系，可以很好的解释它们的蓝移现象，从而更进一步的扩展了这一理论。

The simulation results show that the spring stiffness and initial force have important effect on the poppet valve's opening displacement, the delay-closing time and the closing velocity, and there must be an optimal matching between those two spring factors.

仿真结果表明，在同时保证阀芯有较大的开启度和较短的滞后关闭时间时，弹簧刚度和预紧力因素之间存在着最佳组合：k=10 N/cm，f=15N；同等地改变预紧力比改变弹簧刚度，对阀门的运动影响更大。
