求大神润色一段英文 卤化丁基胶是呼吸器罩体材料的首选，其优良的阻隔性能源自异丁烯链节中密集侧甲基能够有效阻止其它小子的热运动，但密集侧甲基所产生的较大内摩擦损耗也将导致材料的低回弹性，并给呼吸器的生产和使用带来不利影响。采用NR与卤化丁基胶进行共混可提高材料的回弹性，但同时也将以牺牲部分阻隔性能为代价（因为NR对化学试剂的阻隔性能较低）。 Halobutyl rubber is the main choice of the faceblank materials for respirators due to the good barrier property originated from the dense side methyl groups in the predominant isobutylene units which can effectively prevent other molecules from thermal motion. However, great internal friction originated from the methyl groups will also result in low resilience, and finally bring disadvantages to respirators during its manufacture and usage. Blending with NR is an alternative way to improve the resilience. Unfortunately, it will decrease the resistance of the blend unavoidably due to the NR offers rather low resistances to the penetration of chemicals. 由于材料的阻隔性能与渗透剂在材料内部的扩散行为密切相关，本项目拟开展个体防护领域常用的目标毒剂-芥子气在CIIR/NR共混体系中的扩散行为研究，基于Fick第二定律和便准沾染-圆盘穿透时间测试方法建立相应的非稳态扩散方程，基于动态吸附分析和随机行走理论相结合的方法对其扩散机理进行研究，并研究共混体系组成结构及温度对其扩散行为的影响规律。该项目的开展可以为未来罩体材料的设计提供必要的技术参数及理论依据。 Since the barrier property is depended on the diffusion behavior of permeant in material, the sulfur mustard, a target permeant commonly used in personal protection field, through the blends of CIIR and NR will be studied in this project. The unsteady diffusion equations will be obtained based on Fick’s second law and standard spot-disc breakthrough time test, the diffusion mechanism will be interpreted based on the combination of dynamic adsorption analysis and random walk theory, and the influence of structure and temperature on the diffusion behavior will be also investigated. This study will provide necessary parameters and theoretical basis for future material design for faceblanks. |

你这是论文还是标书？是论文就不用将来时了。因为不确定，所以时态就不改了： Halobutyl rubber is the main choice of the faceblank materials for respirators due to the good barrier property originated from the dense side methyl groups in the predominant isobutylene units which can effectively prevent other molecules from thermal motion. However, great internal friction originated from the methyl groups will also result in low resilience, and finally bring disadvantages to respirators during its manufacture and usage. Blending with NR is an alternative way to improve the resilience. Unfortunately, it will decrease the resistance of the blend unavoidably due to 【due to 不能引导从句， 改为 because 或者 since】 the NR offers rather low resistances to the penetration of chemicals. Since the barrier property is depended【改为dependent】 on the diffusion behavior of permeant in material, the sulfur mustard, a target permeant commonly used in personal protection field,【逗号去掉】 through the blends of CIIR and NR will 【如果是论文就不用将来时了，下同】be studied in this project.
