There are five important soft sensor models of moisture have been established in this paper: the moisture model of The Recursive Least Square based on Lethe gene, the moisture model of Principal Component Regression , the moisture model of Partial Least Square, the moisture model of BP Nerve Network, the moisture model based on PLS—BP. All of these soft sensor models of moisture are systematically analysed by using Compound Correlative Coefficient. The factors which influence control of moisture are discussed on detail in this paper.

The relationships between germination of the teliospores of Tilletia conroversa Kühn and soil moisture were studied and it was found that the teliospores of TCK could germinate when the soil mass moisture content reached between 1%-28%(relative moisture capacity 3.75%-100%). The suitable moisture for teliospore germination was between 10%-25% of mass moisture capacity or 17.85%-89.3% of relative moisture capacity. The optimal soil relative moisture capacity was between 65%-75%. There was no difference among most TCK isolates tested at the same suitable soil moisture.

In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.

在毛乌素沙地，喷灌前后土壤含水率等值线垂直分布均具有显著的垂直分层特征；在喷灌结束24h后，喷灌前土壤含水率的垂直分布与喷灌后土壤含水率的垂直分布间地相关性较弱；灌水前土壤初始含水率的概率分布形态均表现为较典型的左偏态分布，灌后土壤含水率分布形态表现为左偏态、右偏形态或正态分布；雨量筒水深概率分布与土壤不同深度剖面层水平方向的含水率概率分布在形态特征上表现出一定程度的差异，雨量筒水深分布与水平层土壤含水率分布、灌后相邻深度层土壤含水率分布、之间的相关程度较高，其相关性随着剖面深度和层间距的增加而降低。

By contrasted with silica gel, the corn hull desiccants by hydrolyzation method and heat treatment method have advantages as stabilization on moisture adsorption, less water of reversible adsorption and high moisture adsorption ratio in high humidity. These desiccants have disadvantages as lower moisture ratio than silica gel in low humidity and slower moisture adsorption speed than silica gel. The corn hull desiccant by derivation method has advantages as high moisture adsorption ratio, high moisture adsorption speed, stabilization on moisture adsorption and hardly any water of reversible adsorption.

通过与变色硅胶干燥剂的对比，通过水解法和热处理法得到的玉米渣皮干燥剂的优点是吸水稳定，可逆吸附水少，在高湿度下吸水率高，不足是在较低的湿度下，吸水率比变色硅胶干燥剂略低，吸水速度比硅胶慢；通过衍生方法得到的玉米渣皮干燥剂的优点是吸水率高，吸水速度快，吸湿稳定持久，几乎不含可逆吸附水，不足是再生后产品容易结块。

The results indicated that,during MV drying,moisture distribution in wood was relatively uniform,without an obvious moisture content gradient along the direction of thickness of wood.Moisture distribution in wood was more uniform in the last period of drying.Above Fiber Saturation Point,the movement of moisture through wood was assumed to be permeable movement of free water and vapor under the action of pressure gradient;below FSP,moisture existing in vapor form in wood moved in response to a pressure gradient.Moisture transfer caused by heat diffusion and a moisture content gradient could be neglected.

研究结果表明：在微波真空干燥过程中，木材内部的含水率分布比较均匀，在厚度方向没有明显的整体性含水率梯度，特别是在干燥的后期，木材内部的含水率分布更加均匀；当含水率在纤维饱和点以上时，木材中的自由水和水蒸气在压力梯度的作用下以渗透流的形式在木材内部迁移；当含水率在FSP以下时，木材中的水分在压力梯度的作用下以水蒸气的形式向木材表面迁移；因热扩散、含水率梯度引起的水分迁移可以忽略不计。
