本文介绍了一种直接测定X射线源几何距离的新方法。该方法适用于不同的X射线源，并暗示了星际尘埃散射形成的X射线晕的存在。时间结构被延迟，并被抹去在光环中。由于所涉及的时间尺度与震源距离线性相关，因此可以通过测量跨晕的阻尼效应来确定震源距离。此外，还可以获得沿视线的粉尘密度分布的信息。(身份验证)
A new method is described for the direct determination of the geometric distance of x-ray sources. The method is applicable to variable x-ray sources and implies the existence of an x-ray halo, which is formed by scattering on interstellar dust. Time structures are delayed and smeared out in the halo. Since the time scales involved depend linearly on the source distance the latter can be determined by measuring damping effects across the halo. Also, information can be obtained about the dust density distribution along the line of sight. (auth)
