A new kind of eigenfunction is presented.

提出了一类新的本征函数。

The parity of the eigenfunction is found by determining what happens to the wave function when r is replaced by -r.

本征函数的宇称可以这样确定：当r用-r代替时看波函数的变化。

Since we get continuous rather than discrete allowed values for E≥0, the positive-energy eigenfunctions are called continuum eigenfunction.

由于对E≥0得到连续的而非分立的允许值，正能量的本征函数叫做连续谱本征函数。
