[化学] 求助翻译一小段话！！

要投到外文杂志上去，发现有些句子自己老是表述不清楚！！发到论坛上，各位英语功力深厚的虫子给翻译一下！！ 随着聚合物掺量的增加，聚合物分子上的磺酸基团的数量也在增加，由于磺酸基团与粘土颗粒间的络合作用，高分子链中负电性极强的磺酸基可以增加粘土表面的负电荷密度， 相应的增加了颗粒的zeta电位的绝对值，所以，聚合物的吸附量也在增大。 随着聚合物高分子链上磺酸基团的数量增多，zeta电位的绝对值增大。当聚合物在粘土颗粒表面吸附后，聚合物分子链上的磺酸基会在粘土颗粒周围形成一层水化膜，阻止泥浆中自由水的渗出，从而滤失量也就变小。 不胜感激！！！！ |

The number of sulfonic acid groups are increasing depend on the increasing of content in polymers.Because of the complexation between the polymer chain and the negative clay surface, the more sulfonic acid groups caused the higher charge densities of clay surface, enhanced the eta potential in absolute terms, therefore, the higher adsorption amount are detected. As more sulfonic acid groups were attached on the polymers, the higher zata potential was found. When the polymer absorbed on clay surface, the sulfonic acid groups-based polymer molecular chain can form a hydrate layer, which prevented mud losing with water seeping, thus the volume of fluid loss became smaller. 随便看下！ [ Last edited by hz-hg on 2009-8-12 at 18:51 ] |

楼主，偶给你翻译一下吧。记得给钱啊! The quantity of sulfonic acid groups in polymers increase with the increasing of content of admixtures in polymers. As a result of the complexation with clay particles, the sulfonic acid groups which have very strong negative can enhance the density of negative electricity, correspondingly, the absolute value of zeta potential increased. Thus the absorption of the polymers increased. The absolute value of zeta potential increased with the quantity of sulfonic acid groups in polymers increasing. Once the polymers were absorbed on the surface of clay particles, a layer of hydration film would formed by the sulfonic acid groups in the polymers around the clay particles. The leaching quantity of slurries decreased because the film prevented the seeping of water in slurries. 文章发表了要请客啊。  [ Last edited by masterpine on 2009-8-12 at 22:15 ] |

The number of sulfonic acid groups increases of polymer with the increase in polymer content. As the acid group of clay hybrid between the polymer chain of highly negatively charged sulfo can increase the negative clay surface charge density, there is an increase in the absolute value of particle zeta potential, along with the increase of the adsorption amount of polymer. As the polymer chain polymer sulfonate groups on the increase, the absolute value of zeta potential increases accordingly. When the polymer absorbed on clay surface, the sulfonic acid groups-based polymer molecular chain can form a layer of clay particles around the membrane hydration to prevent freedom of mud seeping, thereby the volume of fluid loss becoming smaller. |

With the increase in polymer content, polymer molecules on the number of sulfonic acid groups are also increasing, as the acid group of clay particles and complexation between the polymer chain of highly negatively charged sulfo can increase the negative clay surface charge density, the corresponding increase in particle zeta potential in absolute terms, therefore, the adsorption amount of polymer is also increased. As the polymer chain polymer sulfonate groups on the increase in the number, zeta potential increased in absolute terms. When the polymer particles in the clay surface, the polymer molecular chain in the acid base to form a layer of clay particles around the membrane hydration to prevent freedom of mud seeping water, thus the volume of fluid loss will become smaller. |

| As the polymer content increase, the sulfonic acid group number within the polymer molecular also increases. Due to the complexation between the sulfonic acid groups and clay particles, the polymer molecular chain that contains the highly negative sulfonic acid groups will increase the clay surface’s negative charge density and correspondingly enhance the the eta potential in absolute terms, thus the polymer absorption quantity increase. |
