velocity of electron (II) 对于自由电子, H=ap+bm, 薛定鄂得到了含时算符的方程: (dx(t)/dt)H=p+k(t)H k(t)=(a-(H^-1)p)Exp(-2iHt) 他把左边称为总动量, 右边第一项是"宏观"动量, 第二项是"微观"动量 速度同样定义.

Re: velocity of electron (II) Foldy and Wouthuysen (Phys. Rev. 78, pp29-36, 1950) once proposed a canonical transformation on the ordinary Dirac Hamiltonian to make its classical limit better and more meaningful. Among the results that were made more "meaningful" is the velocity issue. I have sent a copy of their paper to our public mailbox (stars_forum1@yahoo.com, password: 123456). 宠辱不惊,看庭前花开花落 去留无意,望天空云卷云舒
