【摘要】 测量了波长２．８４７、３．３７３、４．０２７、９．８７３和１０．２４ｎｍ谱线的一级和高级次光谱强度。给出了以一级光谱强度为标准的高级次衍射光谱的相对效率，并对测量结果进行了分析、讨论。更多还原

【Abstract】 The spectral intensities on different diffracted orders at wavelengthes 2.837nm,3.373nm,9.873nm and 10.24nm are measured by using a grazing incident grating spectrograph.The diffraction efficiencies in higher spectral orders relative to the first order are given. The results are analysed and discussed.更多还原
