In the dry land and garden plot, the soil eroding amount of terraced fields is only 1/3 of that be ploughed directly along the slope. It is difficult that assart along the contour in the dry land and garden plot, after the first 1~2 years, the soil eroding amount will increase at double. From the soil and water conservation point of view, the mode that integrates arbor, shrub and grass in woodland is the best, the mode that plants grass in bare land is the second.

等高作梯的旱耕地和园地土壤侵蚀量仅为顺坡直耕的早耕地和园地顺坡的1/3左右；早耕地、园地等高开垦的强度大，开垦之后1~2年土壤侵蚀量成倍增长；从水土保持角度看，林地乔、灌、草结合模式最好，裸地植草模式次之。

In order to achieve a high concentration and high productivity of exopolysaccharide from Auricularia auricula, the effect of pH on the performance of EPS production in submerged fermentation was investigated. It was showed that the maximum yield of EPS （7.54 g/L） was obtained at pH 5.5, but the mycelial growth rate was enhanced at pH 5.0 and the maximum dry cell weight was

为了实现黑木耳深层发酵生产胞外多糖的高产量和高生产强度的统一，在7L发酵罐中研究不同pH对A.auricula分批发酵生产黑木耳多糖的影响。A.auricula细胞生长的最适pH为5.0，而黑木耳胞外多糖合成的最适pH为5.5。

Its' radiant intension higher tenfold to hundredfold compare with the betatron, spending shorter time on radiogram. higher resolution rate. Hope stream to strong, spot to small commonly.

它产生的韧致辐射强度比电子感应加速器高几十到几百倍，射线照相所需时间更短、分辨率更高。

Five main phenomena were found, firstly, the high plasticity clay could well suitable to large deformation, and had strain-hardening behavior obviously, as well as, the little dilatancy; secondly, there was no correlation between stress paths and shear strength but the stress-strain relations were influenced by stress paths; thirdly, the little stress increment ratio, the higher increase speeding of shear stress and breaking strength under the condition of same initial normal stress; the fourth, the relations between normal strain and normal stress in simple shear test was consistent with which in the single-direction compression test, if there was no dilatancy; the last, the curve of relation between stress ratio and shear strain could be well simulated by hyperbola.

试验结果表明，高塑性粘土能够较好地适应大变形，接触面剪应力与切向应变关系呈剪切硬化型曲线，法向剪胀不明显；接触面剪切强度与应力路径无关，应力应变关系与应力路径密切相关；初始法向应力一定，应力增量比越小，剪应力增长越快，对应的破坏剪应力也越高；无剪胀发生情况下，法向应变与法向应力关系曲线与单向压缩试验具有一致性；应力比与切向应变呈良好的双曲线关系。

Moreover, The melting point of the copolyesters PBEST is much higher than that of the poly (butylene succinate –co-ethylene succinate).

PBEST综合了PET具有高的拉伸强度及PBES具有高的断裂伸长率的特点，因而具有优异的机械性能。

Charcoal brick has hygroscopic and water, and the proportion of high calorific value in use process, and have high mechanical strength.
