[求助] 请帮忙修改(润色)自译的英文摘要

中文内容（原文）：
超级石墨烯是由大量石墨烯片组成的具有二维或三维连通网络的结构体系，其中包含的原子数以亿计。对于如此庞大的系统，目前还没有有效的方法对它进行模拟研究。因此，本项目将建立基于原子层次上的细胞自动机方法来扩展石墨烯材料的研究尺度，分析超级石墨烯的实际应用问题。由于石墨烯具有强度高、重量轻等优良特性，极其适合于作为复合材料结构中的增强体。但要得到高强度的石墨烯增强复合材料，必须了解超级石墨烯结构的界面增强机理，提高石墨烯与基体材料之间的界面性能。因此，本研究将利用所建立的理论模型，定量计算功能化处理对超级石墨烯本身及其增强聚乙烯复合材料整体力学性能的影响，通过优化界面参数进一步分析功能化处理对界面共价键、剪切强度及分子结构胞元等的影响。通过界面成键理论，晶体结构理论及其基本力学原理等，揭示超级石墨烯增强复合体的界面纳观增强机理。其分析方法和计算结果可用来指导超级石墨烯增强复合体的设计与制造。

待修改英文内容：
The super graphite is a two or three dimensional network structure connected by a number of graphite, and the structure is comprised of billions of atoms. So far, there is not yet an effective method to simulate such huge system. Therefore, the project will develop the cellular automata method based on atomic level to expand the study scale of graphite, and analyze the problem in the practical application of the super graphite. Graphite is particularly suitable as promising reinforcing material in complex for its good characteristic of high strength and light weight. But to get the high strength graphite composite, the reinforcement mechanism of super graphite complex at interface have to know so that the performance of the interface between graphite and matrix can be raised. For this reason, the effect of functional processing on the mechanics properties of super graphite itself and its enhanced polyethylene composite are calculated quantitatively by using the theoretical analysis model, that on covalent bond, shear strength and molecular structure cell at interface are further analyzed by optimizing interfacial parameter. The reinforcement mechanisms of super graphite complex at interface are revealed based on the interfacial bonding theory, crystal structure theory and basic mechanical principle and so on. The analysis method calculating results can be used for the guidance of the design and manufacturing of super graphite enhanced complex.
