利用对能量本征函数的一个假设,得到了V(r)=a1r6+a2r2+a3r-4+a4r-6的径向Schrocinger方程的一个解析解,并对偶次送幕势1/r2n势和高次倍谐振子势r2m叠加势给出了它的径向Schrodinger方程的一个解析解的通式. 相似文献

It is shown that the average [O] in the steel can be decreased to 12.86 ppm and there is an optimal [%Si] at the end of melting as 0.11%, at which [O] after vacuum carbon deoxidation (VCD) is minimum. A kinetical model has been deduced to simulate the VCD process. The results show that adding Si before Al is superior to the adding Al before Si with respect to the final [O] in the steel. It is suggested that the melting point of covering slag should be lower than 1550℃, and (FeO+MnO) should be less than 1%, so as to effectively refine GCr15 steel. 相似文献
