径流小区
1.
Continuous observations of surface runoff and through fall in six runoff plots with different kinds of land usage,on karst slopes,and groundwater level in the outlet of the catchment,were carried out.
通过对喀斯特坡地6种不同土地利用条件下径流小区的地表径流和植被穿透雨量以及地下水出口水位变化进行野外定点连续观测研究,结果表明,6个径流小区地表径流系数均非常小,介于0。

The 7Be content in runoff and sediment from different runoff plots under single rainfall event was analyzed.
通过分析次降雨下,来自坡耕地、荒草地、灌木林地径流小区径流、泥沙中7Be含量,发现径流中7Be浓度较小,均值为0。
3.
The soil samples were collected in 6 cultivated runoff plots with grid sampling method, and the soil erosion rates derived from 137 Cs measurements were calculated.
通过在 6个农耕地径流小区的网格点采样 ,经过和经验水蚀模型的比较 ,验证了在 5 0m坡长范围内张信宝、周维芝、杨浩和Walling利用13 7Cs示踪所建立的模型的精确度 ,表明四种模型除了对 1 0m坡长、缓坡度的小区的计算值误差较大外 ,对其他坡长、坡度小区的计算值都比较精确 ,误差小于 1 0 %。
5) residence runoff
小区径流
6) channeled runoff

补充资料:双极性电解槽
分子式:
CAS号:
性质:在电解槽阴阳极之间,若再加入一块或一系列的平行电极,则这些电极向着阳极面的显阴极性,向着阴极面的显阳极性,形成双极性电极。所构成的电解槽即为双极性电解槽。这种槽的功能相当于由多个单室槽串联的多室槽,但直流电只需从两端电极导人,可节省母线和在母线上的电压降,从而达到节能效果。
