The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

It was the large excess entropy of interface phase with a lower atomic density and high degree of disorder that stabilizes the formed nano-structure.

正是低原子密度且高度无序界面的过剩的熵稳定了所形成的纳米晶结构。

Dependence of laser absorption and hot electron generation on atomic number Z and laser incident angle has been observed.

由于界面的影响，厚靶和薄靶的能量吸收和产生的超热电子也有所差别。

According to the principle of continuity of wave function, when different elements react with each other to form compound, the electronic densities of atoms at interface must be equal. Each atom should change the atomic radius to shift their electrical density, then this made huge micro-stress in atoms.

在单质元素原子形成化合物时，由于要满足量子力学的波函数连续原理，要求原子界面上的电子密度相等，各原子在化合时必须通过改变原子半径以达到相同的原子边界电子密度，从而在原子中产生了很大的微观内应力。
