近年来,我们多次接到送样者的来信,询问有关C~(14)数据倒置的问题。所谓C~(14)数据倒置和混乱,就是指柱状样品下层年龄值小,上层年龄值大的情况,或者同一柱状中几个C~(14)数据都没有规律。为此,我们对这个问题进行了一些研究,现撰成此文,与同行讨论,亦可作为对询问此问题的同志的一个答复。 In recent years, we have repeatedly received letters from sample suppliers asking about the inversion of C ~ (14) data. The so-called C ~ (14) data inversion and confusion refer to the lower age value of the columnar sample, the upper age value, or the lack of regularity of several C ~ (14) data in the same column. For this reason, we have carried out some studies on this issue. Now that the article is written and discussed with our colleagues, we can also serve as a reply to comrades who are asking this question.
