按照专家卡拉校夫同志所编的“工厂中的图样管理制度”中，设计部门不仅要制成装配图、另件图和总图，并且还要做出一系列的技术文件，其中有装配系统图一种，这种图对我们大都还是生疏的，因此摘录“机械装配学”的第一章的一部份登载出来，希望各设计部门和施工科及技术科同志加以注意，并运用这方法来制订装配操作规程，编制装配工序。 In accordance with the “Pattern Management System in Factories” compiled by expert Kalagov, the design department not only made the assembly drawing, the separate drawing and the general plan, but also made a series of technical documents including the assembly system This kind of figure is still mostly unfamiliar to us. Therefore, the excerpt of the first chapter of Mechanical Assembly Science was published. We hope that all design departments and construction and technical comrades will pay attention to this method To formulate assembly procedures, preparation of assembly processes.
