随着空间探测技术的发展,发现宇宙空间存在着大量的低能X射线,它们来自太阳和宇宙中各种X射线天体。由于采用大面积有机薄膜做窗口材料以及使用气压稳定度达1mmHg的星戴自动补气系统,使薄窗正比计数管探测低能X射线有很高的探测灵敏度。它被广泛使用在天文卫星中探测空间X射线源的低能X射线辐射。 With the development of space exploration technology, it is found that there are a lot of low-energy X-rays in space, which come from the sun and all kinds of X-ray objects in the universe. As a result of a large area of ​​organic film as the window material and the use of air pressure stability of 1mmHg Star wear automatic gas system, the thin window proportional counter detection of low-energy X-ray detection sensitivity. It is widely used to detect low-energy X-ray radiation from space X-ray sources in astronomical satellites.
