According to classical mechanics and DE Broglie theory, this paper USES quadruplicate equation theory, and deduces the energy spectrum of conical pendulum.

根据经典力学和德布罗意理论，运用四次方程理论，推出了圆锥摆的能谱。

What he did was took de Broglie motion of the electron as a wave and developed a wave equation for such matter waves.

他所做的就是,用电子的德布罗意运动,作为波并且对于那种物质波,给出波动方程。

So, hopefully that kind of clears up that question. And, of course, when the velocity actually is zero, this equation that the de Broglie has put forth is valid for anything that has momentum, so if something does not have any velocity at all, it actually does not have momentum, so you can't apply that equation anyway.

能回答你的问题，当然，如果速度真的是零的话,德布罗意提出的这个方程,只对有动量的物体成立,所以如果一个东西没有速度，它没有动量，也就不能应用这个方程。
