The computer control system of this instrument adopts GT-400-SG four axes motion controller to control the motion of axis x, y, and Z.

本自动书写仪计算机控制系统采用了GT 400 SG四轴运动控制器来控制X轴、Y轴以及Z轴的运动。

A negative face has an outward normal pointing in a direction opposite that of the positive x-axis.

负向的外法线指向与正x轴相反的方向。

The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.

概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。
