1) Wet irrigation
无水层
1.
Wet irrigation could enlarge differences in soil surface temperature, which in turn improved transformation, absorption and transportation of soil nutrient.
采用小区对比法,对无水层栽培和常规浅—干—湿栽培模式进行了对比试验。
2) non-compression aquifer
无压含水层
3) azoic water
无生物水层
4) infinite aquifer
无限含水层
5) semi-infinite aquifer
半无限含水层
1.
Well flow in semi-infinite aquifer is calculated with analytical method,the well flow near the linear recharge boundary is modeled with numerical method.
针对解析方法求解半无限含水层井流问题,对直线补给边界附近的井流采用数值方法进行模拟计算,并将两种方法进行比较,数值计算结果表明,存在补给边界时,抽水一定时间以后降深能达到稳定,但仅仅代表观测点处降深达到稳定,而整个渗流场并未达到稳定状态。
2.
In a semi-infinite aquifer bounded by a channel,a transient flow model is constructed for phreatic water subjected to vertical and horizontal seepage.
对河渠边界控制的半无限含水层,建立垂向入渗与河渠水平渗透共同作用下的潜水非稳定渗流模型;利用Boussinesq第一线性化方法,通过Laplace变换,给出模型的解析解。
6) deep water and riverbed without overburden
深水无覆盖层
