【Abstract】 Permeability is an important parameter for casting coating. In being of testing methods, accurately noting exiguity changes of permeability is very hard, and exists errors are difficult to avoid in artificially noting. In experiment , we have used KH-9250 card connected with computer to collect data and converse A/D of permeability for casting coating. The experiment reveals that the method realizes collecting and dealing with data of precision and automation .更多还原
