You could perhaps compare AC/DC's dogged single-mindedness to that of the Ramones, but even they felt the need to briefly adopt the warp-speed stylings of hardcore punk in the mid-80s, which by AC/DC's standards marks them out as worrying dilettantes.

或许可以拿雷蒙斯，与AC/DC这种抵死不变的作风相提并论。

Firstly, this thesis makes an introduces on the developement of PMSM servo system based on DSP. According to the control theory of AC PMSM servo system, this paper analyzes the coordinate transformation, the rotor magnetic field orientation and the current control strategy of AC servo system. The control strategy is i_d=0. The system is orientates towards rotor magnetic field. Then the mathmatic models of PMSM in d-q coordinate are set up.

假设你在tank一个62级的怪，它有8000护甲，并且有5个破甲效果，然后实际为5750的护甲，因此他将受到48.89%的伤害。

Suppose you are tanking a level 62 mob. Let's give him 8,000 ac raw, and even assume he has 5 sunders stacked, for 5750 final ac, so he will take 48.89% of damage.

假设你在tank一个62级的怪，它有8000护甲，并且有5个破甲效果，就是5750的护甲，那么他将受到48.89%的伤害。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
