这一期的内容,在质量方面,大概仍和前期相仿。开头一篇梁厦先生所撰的“新同位素”,把同位素做了一个赅要的讨论。同位素的研究是在战时才积极扩张而发展的,不但在化学本身,就是在医学、生物学和其他方面,都有重要的关系和影响,这是吾们不可不有的智识。接着芸生先生所撰的“糠醛”一文,把糠醛的性质、制法和功用做了一个系统的介绍和讨论。 The content of this issue is still similar in quality to the previous one. At the beginning, a “new isotope” by Mr. Liang Ha made the isotope a crucial discussion. The study of isotopes was developed only actively during the war, not only in the chemistry itself, but also in the medical, biological and other fields. It is our indispensable wisdom. Followed by Mr. Yun-sheng, “Furfural” article, the nature of furfural, method and function of a systematic introduction and discussion.
