Hello everyone, I am a Chinese college student.

$$\color{blue}{-\frac{\hbar^2}{2\mu}\frac{\partial^2\Psi(x,t)}{\partial x^2}+U(x,t)\Psi(x,t)=i\hbar\frac{\partial\Psi(x,t)}{\partial t}}$$ $$\color{blue}{-\frac{\hbar^2}{2\mu}\left(\frac{\partial^2\Psi}{\partial x^2}+\frac{\partial^2\Psi}{\partial y^2}+\frac{\partial^2\Psi}{\partial z^2}\right)+U(x,y,z)\Psi=i\hbar\frac{\partial\Psi}{\partial t}}$$ $$\color{blue}{-\frac{\hbar^2}{2\mu}\nabla^2\Psi+U\Psi=E\Psi}$$
