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.

X射线荧光光谱仪适合于测量经过背底校正的Ti和Br的Ka线系。对于使用W或Cr射线源和LiF(200)单色晶体的设备,这些线系可以分别在86.09°和29.97°的2u角度处观测到。(2u似乎应该是2θ,衍射物理常用的一个量)
注意 1——遵守所用仪器制造商的建议。选用使Br和Ti的计数率处于探测器线性响应范围内的实验条件。虽然不同的设备总体的实验条件和计数率会不同,但这些差异不会影响分析结果。
