| 6. | Following these two examples of two and three phases , regarding ternary and quarternary metallic melts involving eutectic as melts consisting of three and four non - homogeneuos solutions correspondingly , and using thermo - dynamic parameters of binary metallic melts involving eutectic , calculating models of mass action concentrations for ternary symmetrical melts formed from similar metastable compounds , ternary unsymmetrical melts formed from unsimilar metastable compounds and quarternary metallic melts involving eutectic have been formulated
仿照这两个二、三相熔体的例子，将含共晶体三、四元金属熔体看作由3 ， 4个溶液组成的非均相熔体，并利用含共晶体二元金属熔体的有关热力学参数，针对由同类亚稳态化合物组成的对称型三元系、不同类型亚稳态化合物组成的非对称型三元系及四元系含共晶体金属熔体，制定了相应的作用浓度计算模型。 |
| 7. | Calculated mass action concentrations agree with measured activities , this both shows that these models can reflect the structural characteristics of corresponding melts , and that the regularities obtained from binary metallic melts and ternary mattes involving eutectic are applicable to ternary and quarternary metallic melts involving eutectic
计算的作用浓度与实测活度符合，既证明所制定的模型符合相应金属熔体的结构特性，又证明从含共晶体二元金属熔体和三元熔锍所得到的规律可以应用于含共晶体三、四元金属熔体。 |
