Our calculation shows that, take the HFS model as zeroth order approximation instead, successful many-body calculation on the ground state property of closed shell atoms can also be made.
计算表明，以HFS模型为零级近似，对闭合壳层原子基态亦可成功地进行多体计算。
The zeroth order approximation of the solution can be expressed in terms of confluent hypergeometric functions.
解的零级近似可以用汇合超几何函数表示。
But when the rotary inertia of the hub is close to that of the beam, the zeroth-order approximation model may lead to wrong result.
但当中心刚体的转动惯量接近柔性悬臂梁的转动惯量时，零次近似模型将导致错误的结果。
