Obama sat like a jazz musician on his chair, one heel hooked at an angle, while McCain sat as if he might leap up at any moment, or stood impatiently waiting for his turn to speak.
奥巴马勾起一只脚后跟，看上去像是一个爵士乐手；而麦凯恩则连坐着都好像是时刻准备着奋起作战的样子，如果他站着作答，表情上会看出有些不耐烦。
The results show that the effects on surface roughness are feed speed, depth of cutting , tool rake angle and parts hardness in turn.
结果表明：工件进给速度对表面粗糙度的影响最大，切削深度和刀具前角次之，工件硬度影响最小。
Usually, the output voltage for continuous adjustment was obtained by controling turn-on angle of thyristor.
通常采用控制晶闸管的导通角，而得到输出连续可调的直流电压。
