1.
The experiments showed that PAM has obvious influences on infiltration rate,accumulative infiltration and wetting front: the influences of PAM on infiltration rate were stable and consistent;the denser the PAM concentration,the lower the infiltration rate;the infiltration decay ratio(IDR) of accumulative infiltration due to PAM was a constant,and the IDR were 98.
分析了聚丙烯酰胺(PAM)对一维垂直积水入渗的入渗率、累积入渗量以及湿润锋的影响,试验结果表明PAM对上述指标均有明显的抑制效应:PAM对入渗率的影响具有稳定性和一致性,表现为对应于同一时刻,PAM浓度越大入渗率越低;PAM导致累积入渗量减少的减渗率在入渗过程中为一常数,相对于对照处理(PAM浓度为0)的累积入渗量,10×10-6、50×10-6、500×10-6的PAM溶液的减渗率分别为98。
4) seepage reducing efficiency
减渗效率
5) permeability change coefficient
渗透率变化系数
6) permeability damage coefficient
渗透率伤害系数

灌溉入渗补给系数
coefficient of irrigation recharge into ground water
guan’gai rushen buji xishu灌溉入渗补给系数(eoeffieient of irriga-tion reeharge into ground water)灌溉水补给地下水的数量指标，是灌溉入渗补给地下水的量与灌溉水量之比。影响因素主要有灌溉定额，土壤含水量、土壤质地、地下水埋深、植被情况和气候条件等。 灌溉水入渗，只有在土壤含水量超过田间持水量时，多余的水才能补给地下水。一般在相同的条件下，灌溉定额小、土壤质地粘重与植被差时，灌溉入渗补给系数小(如果灌溉定额很小，可能无入渗补给);反之则大。田间的地下水埋深大(即非饱和带上壤的厚度较大)，故灌溉入渗补给系数小;反之亦然。当引外区的河水或井水时，由灌溉入渗补给系数算得补给地下水量，作为本区的地下水补给量。引河水灌溉，一般灌水定额较大，灌溉入渗补给系数大;引井水灌溉，灌水定额较小，此系数亦小。(金光炎)
