这是ASTM D4764 中关于X射线光谱仪的规格要求，本人对X射线光谱仪是一无所知，想求教各位大侠，下面这段怎么翻译？ X-ray Fluorescence Spectrometer, suitable for measurement of the baseline corrected intensity of the Ka lines of titanium and of bromine. For spectrometers equipped with a tungsten or chromium target and a lithium fluoride (200) analyzing crystal, these lines are observed at 2u angles of 86.09° and 29.97°, respectively. NOTE 1—Follow the recommendations of the manufacturer of the instrument used. Use operating conditions that ensure that the count rate for bromine and titanium are within the linear response range of the detector. Although the base operating conditions and count rate may be different for different instruments, these differences will not affect the outcome of the analysis.
