Comparisons were made between precooling of strawberries in a humidicooling system and a conventional mechanical cold store. 通过草莓在湿冷系统和普通机械冷库中的预冷试验，测定了草莓在这两种预冷装置中的冷却速率。
The frequency identification process is implemented by using the modal test data of the storehouse structure model. 并且，进行了贮仓结构的模态试验，实施了贮仓结构参数频域识别的全过程。
It showed that the modal test using hammer excitation method was successful.The method presented can give reference to the similar spatial structure's modal test. 这说明锤击法的模态试验是成功的，研究结果可为同类空间结构的模态试验分析提供参考。
