目的:研究真空干燥过程的规律,为真空干燥工艺研究及设备的研制提供基础性技术支持.方法:在干燥过程中,实验装置连续记录干燥样品质量和温度变化数据,通过基于实验数据的过程分析,得出干燥过程的主要影响参数及其主要特征.结果:在干燥过程的不同阶段,各工艺参数的影响程度是不同的.结论:为提高干燥过程的总体效率,需要根据干燥过程不同阶段的特点采取合适的工艺技术措施.

A preliminary investigation of diseases and insect pests was carried out in several representative planting regions of Astragalus membranaceus (Fisch) Bge. var mongolicus (Bge.) Hsiao by the spatial and temporal distribution method. The results showed that powdery mildew and root rot diseases are the most serve among the six types of diseases found in A. membranaceus var mongolicus, and meloidae, lima bean pod borer and plant louse are the most harmful among the twenty-three types of insect pests found in this species. Clarification of plant diseases and insect pests in A. membranaceus var mongolicus as well as their damaging extent may provide a reference for the control study regarding the diseases and insect pests in A. membranaceus var mongolicus.
