1952年原子量表这里共刊出两种,一种是苏联方面公布的(第5面),系根据合著的一书(1952年版)制成,简称苏联原子量表;还有一种是苏联和新民主主义国家没有参加的所谓“纯粹与应用化学国际协会”(Internatio-nal Union of Pure and Applied Chemistry、公布的(第6面),原载于本年五月份(五月二十日)美国化学会会志,简称国际原子量表。这两种原子量表的主要区別,是苏联方面已增入第99和100号两种元素,而国际方面只有98种,即比苏联少两种。这两种元素在1950年苏联的化学书中还没有刊出,仅仅相隔一年多,便增加了 The 1952 atomic weight scale was published here in two versions, one of which was published by the Soviet Union (fifth face) and was made under a co-authored book (1952 version), referred to as the Soviet atomic weight scale, or the Soviet Union and the new The so-called Internatio-nal Union of Pure and Applied Chemistry (No. 6), which the Democratic countries did not attend, originally appeared in May this year (May 20) Will be Chi, referred to as the International Atomic Scale. The main difference between the two atomic scales, the Soviet Union has added two elements 99 and 100, while only 98 in the international arena, that is, two less than the Soviet Union Elements of the chemical book in the Soviet Union in 1950 has not been published, only separated by more than a year, it increased
