Comparisons were made between precooling of strawberries in a humidicooling system and a conventional mechanical cold store. 通過草莓在濕冷系統和普通機械冷庫中的預冷試驗，測定了草莓在這兩種預冷裝置中的冷卻速率。
The frequency identification process is implemented by using the modal test data of the storehouse structure model. 並且，進行了貯倉結構的模態試驗，實施了貯倉結構參數頻域識別的全過程。
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. 這說明錘擊法的模態試驗是成功的，研究結果可為同類空間結構的模態試驗分析提供參考。
