本设备用于模拟样品在含有二氧化硫大气环境下的冷凝水－交变气候中的试验的常规条件，实现了对在不同实验室里所得出的试验结果进行比较的可行性，也可以起到快速找出问题所在的作用。
The equipment is used to simulate the conventional conditions of the experiments of the samples in the condensate-alternating climate with sulfur dioxide atmosphere. It realizes the feasibility of comparing the results of the experiments in different laboratories, and also can quickly find out the problems.
