编辑同志:看了《工程机械》1975年第一期中“对无连杆 A 型液压马达中一些问题的探讨”一文后,对文章中讨论的问题很惑兴趣。我在查阅有关资料进行深入学习中,发现有些问题;现对这些问题提出不同看法。由于本人刚开始学习液压方面的知识,对所讨论的问题理解不深,但考虑到为了发展我国液压技术,创制我国的系列产品,使我们的港机早日液压化,现把自己的学习心得寄上。你们认为尚有一点参考价值,请转交有关单位;如果观点错误,请
Editor comrades: After reading the article entitled “Discussion on Some Problems in Connectionless A-type Hydraulic Motor” of the first phase of “Construction Machinery” in 1975, he was very puzzled by the issues discussed in the article. I have found some problems in going through the in-depth study of the relevant information. I now put forward different views on these issues. Since I was just beginning to learn the hydraulic knowledge, I did not understand the issues under discussion. However, considering that in order to develop the hydraulic technology in our country and create a series of products in China so that our port machinery will be hydraulically hydraulized at an early date, on. You think there is a little reference value, please refer to the relevant units; if the views are wrong, please
