編者先生: ‘科學通報’這樣性質的雜誌,是我們早已期望的刊物。它在今日出現,無疑能使我們科學工作者更能得到交流經驗舆互相學習的機會,我想大家一定會高興並爱護這個雜誌的。 現在,有一件事想麻煩編者先生,不知能給我們以協助否? 在我們從事的研究工作中,迫切地需要用Tantalum和Zirconium的化合物作接觸劑。化學工作者都知道,一個接觸作用若是缺乏了適當的接觸劑就成了一個致命的困難。上述這兩種稀有金屬的化合物在國內市場上是極難覓得的。因此我們想請求國內的化學研究工作者協助我們解决這個困難。如有研究機關存有這 Editor: Sir, the magazine of the nature of Science Bulletin is the publication we have long expected. As it appears today, it undoubtedly will make our scientists more able to exchange experiences and learn from each other. I think we will certainly be glad and take good care of this magazine. Now, there is one thing I would like to trouble the editor, I do not know can give us any assistance? In our research work, the urgent need to use Tantalum and Zirconium compound as a contact agent. Chemists know that a contact is a mortal difficulty in the absence of a suitable contact. The above two rare metal compounds are extremely hard to find in the domestic market. Therefore, we would like to ask the domestic chemical research workers to help us to solve this difficult problem. If there are research institutes have this
