X-Ray Emission due to electrification of insulator has been confirmed experimentally. The experimental conditions of X-ray emission due to the electric charge-up effect have been extensively studied with the change of pressure, vacuum, insulator material, atmospheric gas, applied voltage, electric current (DC or AC), and so on. It is found that the X-rays are only strongly emitted when the vacuum is a very narrow range on the 10ィイD1-2ィエD1 Torr. The X-ray emission is very unstable even though we changed the experimental conditions as far as we could control. The physical mechanism of this X-ray emission has been clarified; it is due to electron bombardment.Using this phenomena, we have constructed an X-ray generating device using a 1.5 V battery and high voltage inverter. This device is quite small, and it has been observed that significant strength of X-rays were generated. The X-rays produced by this device was again very unstable, and we tried to find a condition by which the stable X-rays were generated. However, at the present stage of our work, we have not yet found such an experimental condition. We believe that the study of charge-up effect should be needed in the future.

实验证实了绝缘子带电产生的x射线辐射。随着压力、真空、绝缘体材料、大气气体、外加电压、电流（直流或交流）等因素的变化，人们对带电x射线发射的实验条件进行了广泛的研究。发现x射线只有在10 μ l - 1 μ l - 1 μ l - 1 μ r的真空范围很窄时才会强烈发射。即使我们尽我们所能地改变实验条件，x射线发射也非常不稳定。这种x射线发射的物理机制已经澄清；这是由于电子轰击。利用这一现象，我们构建了一个使用1.5 V电池和高压逆变器的x射线产生装置。这个装置非常小，并且已经观察到产生了显著强度的x射线。这个装置产生的x射线也很不稳定，我们试图找到一个产生稳定x射线的条件。但是，在我们目前的工作阶段，我们还没有发现这样的实验条件。我们认为，充电效应的研究在未来是有必要的。
