average soil water content 平均土壤含水量
average soil water content increment 平均体积含水率增量
The results showed that owing to the good ability to absorb water and keep it of PAM, the cumulative infiltration and average water content increased with the increasing of PAM dosage.
结果表明，由于PAM具有良好的吸水和保水性能，其用量的增加使累积入渗量增大，平均土壤含水量增加；
The net water vapor flux is positive always, but its content is low about 21.88% than average state in dry year, and is high about 53.99% in wet year.
无论旱涝年，青海高原空中净水汽通量均呈正值，但旱年比平均状况偏少21.88%，涝年偏多53.99%。
The average soil salt content of desalt region cut down as the cumulative infiltration volume rose and went up with the water concentration and initial water content.
脱盐区土壤平均含盐量随累积入渗量的增加而减少，随入渗水矿化度和土壤初始含水量的增加而增加。
