推出测不准关系结果的那个不等式即:integ(square(abs(a*x*psi+d(psi)/d(x)))>=0是怎么想出来的?我觉得太妙了。或者这个积分因子本身有什么物理意义吗?

初看就是在坐标本征态中同时测量坐标和动量,a是量纲因子......

>integ(square(abs(a*x*psi+d(psi)/d(x)))>=0 --------------------------------------------------------------------------- I could not understand what you typed in here. could you do it in Latex or in C/Fortran/Mathematica >或者这个积分因子本身有什么物理意义吗? ------------------------------------------------------------------------------ as it is, it should be just a math result. the usual derivation is to begin with comutattion relation and use Schwarz inequality. I suppose what you have here is just a form of that inequality.

Integrate[(Abs[a*x*psi+D[psi,x]])^2],{x,-Infinity,Infinity}]>=0
