For further development of the comparison method, the X-ray spectra of laser plasmas of light (Si, S, Cl, K, Ca, Ti) and heavy (Mo, W) elements are studied. Plasma is produced by focusing nanosecond laser radiation (λ = 0.53 μm, E _L = 5 J, τ = 2 ns) onto massive solid targets. The spectra are recorded using two focusing crystal spectrometers in the wavelength range λ = 2 – 11 . A detailed analysis of H- and He-like ion spectra is performed to determine the dependence of the electron temperature (T _e = 500 – 800 eV) on the energy of laser pulses (E _L = 0.5 – 5 J). Recommendations are given for measuring T _e from the spectra of light elements with maximum accuracy. The comparison method is employed to estimate the electron temperature of the plasmas of heavy elements (Mo, W), whose X-ray spectra are complex in structure.

为了进一步发展比较方法，研究了轻（Si、S、Cl、K、Ca、Ti）和重（Mo、W）元素的激光等离子体的 X 射线光谱。通过将纳秒激光辐射 ( λ = 0.53 μm, E _L = 5 J, τ = 2 ns) 聚焦到大量固体目标上来产生等离子体。使用波长范围λ = 2 – 11的两个聚焦晶体光谱仪记录光谱。对 H 和 He 类离子光谱进行了详细分析，以确定电子温度 ( T _e = 500 – 800 eV) 对激光脉冲能量 ( E _L = 0.5 – 5 J) 的依赖性。给出了测量T _e的建议从最准确的轻元素的光谱。采用比较法估计重元素（Mo、W）等离子体的电子温度，其X射线光谱结构复杂。
