请英语高手帮我翻译下面一则化学论文摘要，不胜感激！！

摘要： 以双酚A 型环氧树脂( E -5 1 )为囊芯，脲酫树脂( urea-formaldehyde , UF) 为囊壁， 采用原位聚合法合成微胶囊，制备不同微胶囊含量的聚酯/微胶囊材料。通过电子拉力机测定材料的力学性能，扫描电子显微镜观察试件断面形貌。微胶囊对聚酯材料具有增韧和修复作用。自修复机理是微胶囊在裂纹前端应力作用下，囊壁出现破裂，囊芯环氧树脂流出并流入裂缝，将裂缝面黏合，达到自修复效果。自修复材料的设计及工程应用，对延长材料在受到冲击、加载和高温条件下的使用寿命和提高工程安全具有重要
意义。
高手快出现吧，我还没看到满意的答案啊！

Answer 1

： With polyphenol a type of epoxy resin (e -5 1 for every) core, 脲 酫 resin (urea - formaldehyde, uf) for every wall and the place got into a lawful capsule, the capsule with different levels of polyester a capsule. by the pull of the determination of the materials have to scan electron microscopic studies have this type of thing. a capsule is polyester materials having 增韧 and repair work. since the restoration of mechanism is in a capsule the front-end stress, a breakup, a purse for epoxide resins comes out every lead and into the cracks in the sticks together to achieve since the restoration of effect. since the restoration of the design and engineering applications for extension of material under the impact, loading and the conditions of life and improve the security significance.

Answer 2

With bisphenol A type epoxy resin (E - 5 1) for sac core, 酫 resin urea formaldehyde, urea - (UF) for bursa wall, using in situ polymerization synthesis microcapsule preparation different microcapsule content of polyester/microcapsule materials. Through electronic tensile machine determination of the mechanical properties of materials, scanning electron microscope specimens cross-section shape. Microcapsules on polyester material has toughening and repair function. Since repair mechanism is the crack front microcapsule, bursa wall under stress rupture, appear capsule core epoxy resin outflow and inflows cracks, the fracture surface glue, achieve self-repairing effect. Since restorative materials design and engineering application, to extend materials at impact, loading and high temperature condition and improve the service life of construction safety has important

Answer 3

Abstract: Take the double phenol A epoxy resin (E -5 1) as the pouch core, the urea 酫 resin (urea-formaldehyde, UF) is the pouch wall, uses the home position polymerization law to synthesize the micro capsule, the preparation different micro capsule content polyester/micro capsule material. Through electronic pulling force machine determination material mechanical properties, scanning electronic microscope observation test sample cross section appearance. The micro capsule has the plasticizing and the repair function to the polyester material. From the repair mechanisms is the micro capsule front end the crack under the stress function, the pouch wall presents the breakage, the pouch core epoxy resin flows out and flows in the crack, binds the crack surface, achieves from the repair effect. From the repair material's design and the project application, to lengthen the material in is under the impact, the load and the hot conditions service life and enhances the project to have important
