摘要: 提出了一种构造并精确求解新型势函数的方法.采用这种方法,讨论了一维二次型函数的通解,将这种二次型函数分段连接构造出一种新型一维双势阱模型和新型一维周期势模型,在此基础上得出了这两种新型势模型的精确解。

Abstract: We propose an approach to obtian the analytical solution for a new kind of potential constructed by some pieces of solvable potential if their general solution could be obtainde. We exactly solved two kinds of potentials constructed.by this method, one is a double-well potential and adother is a periodic one, both of them are smoothly joined by pieces of quadratic potential curves.

Key words: exact solution, construct, double-well potential, periodic potential
