【求助】USP 微生物检定翻译讨论

71，61中均没有这句话。。。请问是哪个章节

From the information available for the preparation to be assayed (the “Unknown”), assign to it an assumed potency per unit weight or volume, and on this assumption prepare on the day of the assay a stock solution and test dilution as specified for each antibiotic but with the same final diluent as used for the USP Reference Standard.
从供试品可知的信息（未知物），确定一个设想的效价/单位重量或体积，根据这个假设在分析当天制备储备液并对各抗生素按指定的方法稀释但是最终稀释剂应与其USP标准品所用一致。

The assay with five levels of the Standard requires only one level of the Unknown at a concentration assumed equal to the median level of the Standard.

标准品5个等级的分析仅要求一个假定的未知物浓度与标准品的中位数相等

USP:<81> ANTIBIOTICS—MICROBIAL ASSAYS

非常感谢帮忙，^_^
