Some material, especially biomaterial, will shrink during thedrying process. In the experiment, drying curve and shrinkable curve of fresh pea is measured. Volumetric shrinkable coefficient is also introduced and measured.

• 针对一些生物材料在干燥过程中会发生收缩这一特性,以市场上新鲜豌豆为研究对象,测得了该物料在不同干燥条件下的干燥曲线、收缩曲线,引入并求得了体积收缩系数。
