湿蚕蛹干燥过程的实验研究

The drying process of wet silkworm chrysalises , which are the subproducts of the silk production industry , is experimentally studied .

对缫丝副产物湿蚕蛹的干燥过程进行了实验研究，采用垂直穿流热风强制对流干燥方式。

These chemicals do not harm the caterpillars , but make them toxic to predators even after they emerge as adults from their chrysalises .

塞缪尔颇有研究还收集了毛虫和蝶蛹一周光景，它们便能化身为蝶。

They are kept in the hands of professionals for three or four days to ensure that the chrysalises hatch properly and the butterflies are in prime condition for the wedding day .
