本院苏联专家达维道夫教授对本文的评介： 本文所进行的研究是有创造性的，是直接在矿内运转中的机器上进行的。据我所知：在中华人民共和国这种研究还是第一次。 作者在本文中得出的关于抽齿能使功率消耗降低的数据是令人信服的。这些数据说明功率的降低是很明显的，平均降低了２０％。由於作者在称截当重量时，对天秤本身精度的怀疑，因此所得磨损的数据并不十分可靠。 我认为本文应在“北京矿业学院学报”上发表。本文仅仅是在生产条件下研究采矿机械工作的初步尝试。亳无疑问，研究生本人和其他研究人员在今后做新的研究时，应该继续采用这种方法。
Professor Davidsdorf, a Soviet expert on our hospital, commented on this article: The research carried out in this article is creative and is carried out directly on machines operating in mines. As far as I know: This kind of research is the first time in the People’s Republic of China. The author’s conclusion in this paper is that the data on the reduction of power consumption caused by tooth extraction is convincing. These data show that the power reduction is obvious, with an average reduction of 20%. Due to the author’s skepticism about the accuracy of the scale itself when it comes to weight, the resulting wear data is not very reliable. I think this article should be published in “Journal of Beijing Institute of Mining”. This article is only a preliminary attempt to study mining machinery under production conditions. There is no doubt that graduate students and other researchers should continue to adopt this method when doing new research in the future.
