primary drying

Results show that some primary factors affect sol-gel transition, gelation formation and quality. These factors include the temperature of solation formation and sol-gel transition, drying time.

对溶胶-凝胶法的研究发现：溶胶形成温度、凝胶干化温度及干化时间等都是影响干凝胶质量的主要因素。

The primary drying and the secondary drying are two important stages of a freeze-drying process.

升华干燥和解析干燥是 冷冻干燥 过程的两个重要阶段.

At the primary stage of drying, the maximum value of elastic tension strain of the timber surface increased with drying temperature rising, and decreased with increment of equilibrium moisture content ( EMC).

干燥前期，木材表层伸张弹性应变最大值随着温度和平衡含水率的增加而减少，木材表层塑性应变则随平衡含水率的增加而增加。
