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。
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。
