"Please erase your image of electric cars being like golf carts," a spokesman for Japan's fourth-biggest automaker said before taking a zero-emission vehicle out for a spin.
Finally, we apply the theory to study the quantum phase transitions of one-dimensional anisotropic XY quantum spin chain in a transverse field at zero temperature.
最后我们采用李—杨零点方法对一维横场各向异性XY模型在零温下的量子相变作了较为系统的研究。

The results show that: (i) the spin-polarization of electron can not be produced in the anti-parallel magnetic barriers structure at zero bias voltage;
