与在去离子水中相比，材料在盐水中饱和吸水率、初始时吸水速率和水扩散系数较小。

In salt water the composites had less water absorption, absorption rate and diffusion coefficient than that in di water.

实验结果表明，该树脂中的羟基改为乙酸基后可降低树脂的饱和吸水率，并增大水在树脂中的扩散能力。

The experimental results show that the replacing of the hydroxy groups with acetoxy groups in the resin causes less water uptake, but increases the diffusibility of water in the resin.

尿素即使在饱和浓度下，高吸水树脂仍保持在65%以上的吸水率。

When the concentration of urine was in saturation, however, the rate of absorbing water of the resin was stile more than 65%.
