x光机 是产生X光的设备，其主要由X光球管和X光机电源以及控制电路等组成，而X光球管又由阴极灯丝 （Cathod）和阳极靶（Anode）以及真空玻璃管组成，X光机电源又可分为高压电源和灯丝电源两部分，其中灯丝电源用于为灯丝加热，高压电源的高压输出端分别夹在阴极灯丝和阳极靶两端，提供一个高压电场使灯丝上活跃的电子加速流向阳极靶，形成一个高速的电子流，轰击阳极靶面后，99%转化为热量，1%由于轫致辐射产生X射线。
X-ray machine is the equipment that produces X-ray. It mainly consists of X-ray bulb and power supply of X-ray machine and control circuit. X-ray bulb is composed of cathode filament (Cathod), anode target (Anode) and vacuum glass tube. The power supply of X-ray machine can be divided into two parts: high voltage power supply and filament power supply, in which filament power supply is used to add filament. The high-voltage output terminals of heat and high-voltage power supply are clamped at both ends of cathode filament and anode target respectively. A high-voltage electric field is provided to accelerate the active electrons on the filament to the anode target, forming a high-speed electron flow. After bombarding the anode target surface, 99% of the electrons are converted into heat, and 1% of the electrons are generated by bremsstrahlung radiation.
