摘要: 在质量守恒的基础上，运用拉乌尔定律和道尔顿分压定律,对以摩尔分数比为3∶3∶4比例充入到ICF靶丸内的氘气、氚气和氘化氚三元系的热核燃料，在工作温度为22，24，26，28和30 K下处于相平衡时气液两相的组分组成进行了分析讨论。结果显示:工作温度为22 K时，随着充气压强从1 MPa增大到5 MPa，液层中氘气的摩尔分数从0.251增大到0.290，氚气的摩尔分数从0.350减小到0.310；气泡中氘气的摩尔分数从0.322增大到0.365，氚气的摩尔分数从0.278减小到0.241。充气压强为5 MPa时，随着工作温度从22 K提高到30 K，液层中氘气摩尔分数从0.290减小到0.261，氚气的摩尔分数从0.309增大到0.341；气泡中氘气的摩尔分数从0.365减小到0.302，氚气的摩尔分数从0.241增大到0.298。Abstract: According to Raoult's law and Dalton's partial-pressure laws, the mixture of D2, T2 and DT fuel components in the proportion of 3∶3∶4 in an ICF target is analyzed on the basis of mass conservation, under the vapor-liquid equilibrium phase at several work temperatures (22, 24, 26, 28 and 30 K).The result is that at 22 K, with filling pressure increasing from 1 MPa to 5 MPa, the mole fraction of D2 increases from 0.251 to 0.290, the mole fraction of T2 decreases from 0.350 to 0.310 in the liquid fuel, and the mole fraction of D2 increases from 0.322 to 0.365, the mole fraction of T2 decreases from 0.278 to 0.241 in the gas fuel. When filling pressure is 5 MPa, with work temperature increasing from 22 K to 30 K, the mole fraction of D2 decreases from 0.290 to 0.261, the mole fraction of T2
