Its shape was obtained by installing a circular ring at the confluence point of two conical revolutions.

在两个圆锥形旋转的交汇点安装一个圆环就构成了楼梯整体的基本形状。

But the arithmetic product operation is needed to determine a pixel belonging to which circular ring, which consumes much time.

但由于确定各像素点属于哪一个圆环需要进行复杂的乘积运算，耗费了大量时间。

There is no way that you could irradiate a crystal of nickel with a single beam of x-rays and get that circular ring pattern if the electron beam were behaving as a particle beam only.

没有什么其他的途径,可以让镍晶体发射,单束X光来,继而得到环状图案,如果电子束,是以粒子束形式出现的。
