Abstract: The environment and architecture of Application Softwares of Atmospheric Corrosion Database for Materials (ASACDM) which in implemented on the computer IBM/PC-XT are described. And in detail the program in the application of ASACDM are stated. The advantage of this ASACDM system iIs convenient to operate and easy to master. Its use will have more important significance for national atmospheric corrosion test station to do management in a scientific way.
