求翻译：它与X射线机的一个重要不同是，射线源始终都在不断地辐射射线，而X射线机仅仅在开机并加上高压后才产生X射线，这就使射线机的结构具有了不同于X射线机的特点。是什么意思？

It is an important difference with the x-ray machine -ray source is always in radiation -rays, and x-ray machine only in the boot and coupled with the high pressure after the x-ray, which makes the structure of the -ray machine Unlike the characteristics of the x-ray machine.

It with X beam machine one important different is,  the beam source throughout all in unceasingly radiates  the beam, but X beam machine merely after starting and adds on the high pressure only then to have X beam, this enable  the beam machine structure to have has been different with X beam mac

An important difference with x ray machine is, the radiation sources are always in constant radiation, and x-ray machine powered on and just with high pressure to produce the x-ray, which makes ray machine structure with different characteristics than the x-ray machine.
