Comparisons were made between precooling of strawberries in a humidicooling system and a conventional mechanical cold store. 通過(guò)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. 并且，進(jìn)行了貯倉結構的模態(tài)試驗，實(shí)施了貯倉結構參數頻域識別的全過(guò)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(shuō)明錘擊法的模態(tài)試驗是成功的，研究結果可為同類(lèi)空間結構的模態(tài)試驗分析提供參考。
