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.

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

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.

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

由于各区域之间土壤、气候条件的差异，各地土壤水分循环4个阶段的划分也不尽相同；黄河流域不同旱作类型区土壤水分动态变化比较结果表明：就季节变化而言(来源：A70b0B0bC论文网www.abclunwen.com)，由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势，而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期；而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段；就垂直变化而言，黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

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。
