亲们，江湖告急，求翻译！有关高吸水性树脂的合成与溶胀性能

| In addition, the repulsion between and among different chains is enhanced. The water absorbency increases as the force caused by chain expansion in the network increases (Pourjava & Amini-Fazl, 2007). However, when the neutralization degree is too high, the Na+ concentration on the network of graft copolymers being formed increases, and the electrostatic repulsion between charges causes the contact of the heavy metal and coordination groups on the surface of the resin and chelate formation difficult. The excess in the degree of neutralization is not conducive to resin adsorption. However, with the increase in the neutralization degree, the shielding effect of Na+ on the carboxylic acid anion in the system gradually appears, which weakens the repulsion among the chains or adjacent carboxylic acid anions on the same chain and reduces the extension driving force of the network. Therefore, when the neutralization degree is too high, the swelling capacity is reduced. |

此外，不同链间的相互排斥作用也增强了。其吸水率随着网络结构中链膨胀作用力的增强而增加。但当中和度过高时，形成的接枝共聚物中，其网络结构中的钠离子聚集浓度会增加，而且在两电极间存在静电排斥作用，这将减弱树脂及螯合物表面上的重金属（离子）与有机配体（或官能团）间的联系（连接）。中和度的过量并不会引起树脂吸附，但随着中和度的增加，系统中钠离子对羧酸阴离子的屏蔽作用会逐步显现，这会减弱不同有机链间或同一链内相邻羧酸阴离子间的排斥作用，还会减小网络结构扩展的驱动力。因此当中和度过高时，其膨胀量将减小。 |
