本方法可以改变旁瓣和零点位置，改变各旁瓣的相对高度。

Moreover, the position of sidelobes and zeroes and the relative height of any sidelobes can be changed by using this method.

若是弹簧机每次归零以后零点位置都不准确，那就可能是驱动参数的问题。

If the spring machine after each zero zero position is not accurate, it may be the problem of driving parameters.

And then we calculate changes, the convention is understood with respect to what is the zero, right.

然后我们计算改变,这个约定就是用来规定零点的位置的。

The absolute number that you assign to it is something that's arbitrary. You have to set what the zero is. And so there's a well-understood convention for what the zero is.

你指定给它的绝对值是有任意性的,你需要设定零点的位置,因此有一个经过充分研究的,关于设定零点的约定。
