本刊经常收到一些自认为是自然科学方面发明、发现的文稿。投稿者学历分高、中、低三类。其内容涉及数、理、化、天、地、生诸多领域。他们的共同特点是做起“学问”来如痴如醉。大凡向《科学新闻》周刊投稿,总是出于对我们的信任,而令我们为难的是,既不能作出肯定的答复,又不能不屑置辩。俗话说,愚者千虑,必有一得,况且这些作者未必是愚者。科学史上的许多发明不就是这样走过来的吗?我们有选择地刊登部分文章,只好让读者自己去评鉴了。本期刊登的是湖北省襄樊市敏芝气味科学研究所所长李德敏先生等从实践中得到的体会。 This journal often receives contributions that we consider to be inventions and discoveries in the natural sciences.

It is always out of trust for us to submit articles to the weekly “Science News”, and what makes us embarrassed is that we can neither affirm it nor disagree. As the saying goes, fools think twice, there must be a gain, besides these authors may not be fools. Many inventions in the history of science did not come over like this? We have chosen to publish some of the articles, but to allow readers to evaluate their own. This issue is published in the Xiangfan City, Hubei Province, director of the Institute of smell science Li De Min get experience from practice.
