Other requirements are a low waterabsorptioncapacity and a sufficient raw density.
其他的要求就是低的吸水性和足够的原材料密度。

Real water injection rate in water injection well will change when system pressure fluctuates or formation waterabsorptioncapacity changes.
注水井实际注水量随系统压力波动或地层吸水能力的变化而改变,这是针型阀或井下固定水嘴无法避免的缺陷。

The influences of polymerization conditions and hydrolysis conditions on the capacity of water-absorption of graft copolymer were investigated. In addition, two synthetic methods were compared.
