Garrigue scrub woodland a secondary formation derived from the original mixed forest , characteristic of limestone areas of the mediterranean region , with low rainfall and thin , dry soils 咖里哥宇群落：是（地中海区常绿矮灌木）多矮小植物，起源于原始混合森林的次级群落，该群落具有的低降雨量及稀薄干燥的土壤，是地中海石灰岩地区的特征。
A new concept , the skeleton elastic wave velocity ( sewv ) , was introduced to replace the velocities of dry soil , which could reflect the engineering characteristic of soil more accurately . new methods to calculate sewv from measured velocities in saturated soil were suggested ( 6 )提出了含水土体骨架波速的概念，用其代替干土体波速的概念，能更好地反映工程土体的性状。 ( 7 )提出了由实测饱和土体波速计算骨架弹性参数及骨架波速的方法。
The experiments reveals that : the amount of water vapor transfer is affected by both water content gradient and the value of water contents , when the water content of one end is approximate , the water content gradient increases , then the amount of water vapor transfer increases ; when the water content gradients are approximate , the amounts of water vapor transfer can get great differences if the water contents are different , under this condition when the water content of the dry soil is very little , the amount of water vapor transfer is much greater ; the differences of density hav n ' t great effects on water vapor transfer , but have some effects on the admixture transfer , when the density is smaller , the amount of admixture transfer is greater . the water vapor transfer finishes more quickly and need less time , and the liquid water finishes more slowly and need less time 当一端含水量一定时，增加含水量梯度，则气态水迁移量增大；当含水量梯度相近时，气态水迁移量随含水量不同可能相差很大，这种情况下当较干段含水量特别小时，气态水迁移量相对较大；密实度的大小对于气态水迁移的影响并不明显，但对液态水和气态水的混合迁移有一定的影响，在相同的实验时间内，土体密实度较小，则混合迁移量相对较大；气态水迁移完成速度较快，所需时间较短；液态水迁移完成速度较慢，所需时间较长。
Since there was very little rain , they could not cultivate in the usual way so brother tian tried a new method of shallow planting . in this way , the water that was scarcely retained by the soil was kept beneath the surface after ploughing , and the dry soil that was dug up served to block the sunlight from evaporating the moisture underground 由于雨水少，耕种方式当然不能像往年一样，田师兄于是尝试着种浅一些，这样仅有的水分经过翻地后埋在地下，翻起的乾土刚好阻挡了阳光直接吸收地下的水分。
( 3 ) study of triaxial test of dry soil and the formation of shear band in triaxial specimen of fly ash . because the digital image processing technique can directly measure the axial and radial deformation of soil specimen in any moisture , general triaxial apparatus can be used to do the triaxial test of dry soil . in the study of the triaxial test of dry soil , the stress - strain characteristic is compared with that of the saturate soil at the same condition （ 3 ）干土的三轴试验以及粉煤灰三轴试样剪切带形成的试验研究：利用土样变形数字图像测量技术可以直接量测任意含水量土样的轴向和径向变形，对干土和饱和土进行三轴试验，比较了干土和相同条件下饱和土的应力应变特性。
