Now the method has application at large . because the laser - produced plasmas are rapidly varying , temporal resolution of spectral features is important to investigation of x - ray radiancy evolvement with time , many dynamic plasma processes and radiation transport . soft x - ray time - resolved diagnosis technology have had quiet great progress since from sixty " s end to seventy " s early 由于激光等离子体变化快，且其x射线辐射的时间特性包含有丰富的物理信息，因此时间分辨的x射线辐射特性诊断是研究激光等离子x射线辐射随时间的演变，各种动力学过程和辐射输运等物理问题所必需的关键诊断技术。
