google一下就可以看到原文了。从上下文来看,这里的standardization明显是指滴定剂的标定,与被分析物无关。见上下文:
Titrant standardization by titration of an accurately know quantity of standard
The standard deviation of this result is a combination of that for the one-step standardization and sample titration steps.
我觉得这里的single-point standardization是指用一种标准物质标定滴定剂。分析化学学得不好,对此不敢肯定,但standardization为滴定剂的标定是毫无疑问的。

Titrimetric analyses are often performed with single-point standardization.standardization of a base titrant solution,used to determine the amount of acid in a sample,is often performed using a known,dry weight of potassium hydrogen phthalate(KHP)as a standard.There is one proton,or equivalent,per mole of KHP.
滴定分析通常是由被单点标定的溶液来完成的。如碱性滴定溶液的标定,通常用一定量的酸性物质来标定的,这种酸性物质通常以已知一定数量的干基邻苯二甲氢钾作为标准。每摩尔的KHP含等量的H离子数。
wrong or right?
