In standard reference channel, ITU standard reference creates a comb spectrum with fixed wavelength.
在参考通道，ITU标准参考模块的输出是具有固定波长的梳状光谱。
Analytical procedures used to Draft — Not for Implementation characterize a reference standard should not rely solely on comparison testing to a previously designated reference standard.
用于标准品界定的分析方法不应仅仅是和先前的指定标准品进行比较实验。
As and ar in the formula are peak area or peak height of internal standard substance and reference substance, Cs and CR are density of internal standard substance and reference substance separately.
式中as和AR分别为内标物质和对照品的峰面积或峰高，Cs和CR分别为内标物质和对照品的浓度。
The method has been applied to the determination of rare and rare earth elements in standard reference shale sample (GBW 07107)and standard reference stream sediments(GBW 07305 and GBW 07310).
对页岩标准物质（GBW 07107）和水系沉积物地球化学成分分析标准物质（GBW 07305、GBW 07310）的分析，测定值与标准值相一致。
