英文摘要内容要与中文摘要内容相对应,采用第三人称表述(不要出现“In this paper”“We”等口吻)。应符合英文语法规则,用词规范、准确,以过去时态叙述所做的工作,使用现在时态叙述研究得出的结论、规律。不能对中文摘要进行直译(中文式英语),更不能只简单使用翻译软件、AI工具等进行翻译。英文摘要撰写完成后,建议找专业英文老师协助修改,使内容趋于完善。
Abstract:To determine the optimal formulation strategy for methane-based mixed modified propellants,bubble point temperatures of four binary and two ternary methane mixed systems were analyzed across varying component ratios. Using different equations of state and mixing rules,eleven bubble point calculation models were established. The accuracy of these models was evaluated with experimental data,and the optimal model was employed to explore the optimal formulation strategy of mixed modified propellants. The results indicate that the CH4+C2H6 mixed system shows the best improvement in bubble point temperature. With a C2H6 mass fraction of 20.4% and a pressure of 0.3 MPa,the bubble point temperature of the CH4+C2H6 mixed modified propellant reaches 128.71 K,which is 2.0 K higher than that of pure methane. Compared with the binary mixed systems,the ternary mixed system shows no advantage in increasing the bubble point temperature of the propellant,as its effect intermediate between the two corresponding binary mixed systems.
