If we disregard the minor tectonic features, the world’s principal mountain systems may be generalized and schematically represented in Fig. 1. This simplest pattern of geotectonics is very speculative. It leads us immediately to

在一九五五年本刊中,笔者曾写一文介绍原子量的测定方法,即化学法、气体密度法和质谱法。近十余年来,用前两种方法从事原子量测定的科学家已寥寥无几,而原子量测定渐趋于采
前言在薄层法的定量计算方法上,有使用薄层色谱定量仪和采用洗脱后再进行比色测定的方法。但因前者仪器昂贵,后者操作繁杂,不宜于大批样品的定量分析。此外,也有用M· Ka-
