在现代化工业建设中,原材料、半成品、土壤性质、设备管道安装质量等需要经常检验,检验方法的迅速准确与否,对建设速度和工程质量有着直接的影响,所以测试方法在工业建设中占有十分重要的地位。这次,在冶金工业技术革新技术革命展览会中展出的几种测试方法和仪器都是工程技术人员在实践中经过广泛调查研究,结合工程实际需要,搜集有关的科学试验新成果,经过学创结合,从实践中摸索出来的。因此,它们都具有设备简单、测试精确、迅速等优点,可供各单参考应用。——编者
In the modern industrial construction, the quality of raw materials, semi-finished products, soil properties, installation quality of equipment pipelines, etc. need to be inspected frequently. The rapidness and accuracy of inspection methods have a direct impact on the construction speed and project quality. Therefore, the test method occupies a very large part in industrial construction. Important position. This time, several test methods and instruments that were exhibited in the Metallurgical Industry Technological Innovation and Technology Revolution Exhibition were investigated and researched by engineers and technicians in practice, combined with the actual needs of the project, and collected relevant new results of scientific experiments. Create a combination, from the practice of groping out. Therefore, they all have the advantages of simple equipment, accurate testing, and rapidity, which can be used for reference applications. --editor
