Local artifical boundary condition in time domain is based on concept of travelingwave. It cannot simulate zero-frequency component(evanescent motion) generally.
时域局部人工边界是以行波概念为基础的,原则上不能用于模拟零频分量(消减运动)。
To reach the ground state, physicists had to cool their beams to nearly absolute zero. They also had to make the quanta as large as possible by making a beam stiffer to increase its frequency.
为了实现真正的基态,物理学家不得不将光束冷却到接近绝对零度,他们还要通过使光束保持静止来增大其频率,让量子尺度变得尽可能大。
For discrete convolution equation set, generally, people use Fourier transform method to solve. But in some positions, zero frequency will lose.
对于离散卷积方程组,一般采用傅氏变换的方法求解,但在某些特定系数的情况下,零频率丢失。
