Microwave-vacuum (MV) drying characteristics of plantation Masson pine (Pinus massoniana) were studied experimentally for various levels of microwave radiation time, initial moisture content (MC), vacuum level and wood thickness. The results show that the process of MV drying for wood can be significantly divided into a short accelerating rate drying period, a long constant rate drying period and falling rate drying period, and the second drying period can extend to levels of mean MC below the fiber saturation point. With the increase of initial MC and microwave radiation time, the drying rate...

弄干种植园马森松(Pinus massoniana ) 的特征的微波真空(MV ) 为微波放射时间，起始的潮湿内容(MC ) ，真空水平和木头厚度的各种各样的层次试验性地被学习。为木头弄干的 MV 的过程能显著地被划分成弄干时期，弄干时期的长经常的率和弄干时期的掉落的率的短加速率的结果表演，和第二个弄干的时期能在纤维浸透点下面延长到吝啬的 MC 的层次。随起始的 MC 和微波放射时间的增加，木头的弄干的率显著地增加。真空水平以一个稍微积极的方法影响弄干的率。在 2 ～ 6 厘米的范围以内，弄干的率上的样品厚度的效果能是可以忽略的。
