| 本文采用热分析方法研究了天然橡胶和炭黑结合物的TG/DSC曲线，应用热分析动力学对DSC曲线分析结果进行证明，结果表明：用TG/DSC热分析曲线对炭黑与天然橡胶的混合物进行分析时，分析结果与宏观的数据相符合；并且，加入炭黑后的天然橡胶分解所需平均活化能比天然橡胶的活化能低，混炼法制备的炭黑与橡胶的混合物分解所需的活化能比用溶剂法制备的混合物分解所需的活化能高。这些与DSC曲线分析结果相一致。 |

| In this paper, thermal analysis of the natural rubber and carbon black conjugates TG / DSC curves, application of the DSC curves of thermal analysis kinetics analysis results show that the results showed that: TG / DSC thermal analysis curves of carbon black and natural rubber mixture analysis, results consistent with the macro data; and adding carbon black natural rubber after the decomposition of the average activation energy required for the activation energy lower than that of natural rubber, prepared by mixing a mixture of carbon black and rubber decomposition than the activation energy required for solvent mixture prepared by decomposition of the high activation energy required. The DSC curve analysis and consistent with the results. |

照你的意思，可以如下翻译， In the paper, TG / DSC curves of the natural rubber and natural rubber conjunct with carbon black was studied by the method of thermal analysis, and the thermal kinetic method was uilized to verify the analysis result of the DSC curves. It was found that the data of TG / DSC thermal analysis to the conjunct is well fitted with the macroscopical data. In addition, the average active energy is required higher for the decomposion of the mixture, as compared with that of pure natural rubber. The disassembled active energy of the conjunct prepared by the refined method is higher than that of the mixtures synthesized by the solvent method. Such results is consistent to that of the DSC curve analysis. |

实际上，一般摘要中，TG / DSC curves 与 thermal analysis 有点重复。 实际你的意思是热分析的结果与宏观或动力学结果相对比，所以你的中文摘要都写的优点问题！而且你的宏观数据是什么？是指大规模橡胶的分解？有点不明确？ 按照我的想法，仅供参考。 In the paper, decompostion process of the natural rubber conjunct with carbon black was studied by the method of thermal analysis, and the thermal kinetic method was uilized to verify the analysis result of the DSC curves.
