膜下滴灌风沙土盐分变化及分布特点

, 2005
通过对已进行膜下滴灌2a和5a的改良风沙土电导率和总盐分的测定,探讨不同滴灌年限土壤盐分变化及分布特点。研究表明,在膜下滴灌与冬灌和春灌相结合的条件下,土壤表层0～30cm盐分逐年下降,但脱盐效率也不断降低;盐分在土壤中分层明显,在水平方向,距离滴头越远,盐分越重;垂直方向,土壤盐分最低值位于表层20～40cm处。在表层0～40cm的土层中,靠近薄膜边缘盐分差异较大;随着滴灌年限的增加,脱盐区范围增大,特别是水平脱盐距离增加明显。不同滴灌年限的深层压盐区变化不大,膜间聚盐区位于膜间裸地并延伸到薄膜内 ...

ON THE ANALOGY BETWEEN THE CURRENT DENSITY DISTRIBUTION IN A THIN CONDUCTIVE PLATE AND THE ANTI-PLANE SHEAR PROBLEM

, 2006
定量分析电流密度在含裂纹载流薄板内的分布是当前利用电流热效应止裂技术中一个首先要解决的问题.由于裂纹的存在,电流密度在裂尖形成带奇异性分布的高度密集.现有的分析方法往往比较复杂或局限于特殊布置形式的裂纹.通过电流密度分布与弹性力学里反平面剪切问题的比拟,把分析含裂纹载流薄板内电流密度的分布等效于考虑相应的Ⅲ型裂纹问题,并比照Ⅲ型裂纹的应力强度因子来定义电流密度因子.而对于裂纹问题的处理可采用分布位错法这一断裂力学里便利有效的分析手段.由给出的算例可见 ...
