Timeresolved measurement system of Xray spectroscopy was constructed by coupling a gated MCP with a flat crystal spectrometer, and the Kshell emission spectra from the corona of laserirradiated aluminum plasma, were measured with a time delay of about 1ns and with an exposure time of about 200ps. Using the approximation of steady collisionalradiative equilibrium model, the interstage line intensity ratios of the Kshell lines of aluminum were given as a function of electron temperature and density. The electron temperatures were deduced from the line intensity ratios. The diagnosed electron temperatures of the plasmas were 1.190(1±27%),1.165(1±27%), and 1.525(1±27%)keV respectively at laser intensity of 2.319×1014, 1.937×1014, and 3.946×1014W/cm2 。
