波函数的模平方正比于体系处在其位形空间各个点的几率密度。

The square modulus of the wave function is proportional to the probability density of finding the system at each point in the configuration space.

并将模加、模乘、模平方运算集中设计成了一个多功能运算器，使控制电路更加简单。

The modular addition, modular multiple and modular square are placed in the ALU to simplify the controller.

根据模平方运算自身的特点，选用了多项式基进行运算，使模平方运算在一个时钟周期完成，比直接调用模乘运算提高一半以上的速度。

Using multinomial radix, the modular square will be finished in one period of the clock, which is faster than using the point multiplication directly.

First thing you can tell is that if you find the length of this vector, you'll find the square of the x and the square of the y.

首先你可以知道的是,如果你已有了这个矢量的模长,你就可以得到 x 和 y 分量的平方

We know it's going around in a circle because if I find the length of this vector, which is the x-square part, plus the y-square part, I just get r square at all times, because sine square plus cosine square is one.

我们之所以知道它做圆周运动,是因为我求出了这个矢量的模长,也就是 x 的平方加上 y 的平方,我就得到了它在任意时刻的模长平方,因为正弦平方加余弦平方始终等于1
