Assuming q^, qo, to be independent of temperature and 



integrating, we get : 



a = cj' c^ ^ '^'- '^'' 



But as 



C\ + G, + = 1, 



and G,"+CJ' + = 1, 



we have

relations quite analogous to that represented by equation (11). 

 Equations (23) represent the fusion curves, surfaces, etc. accord- 

 ing to the number of the components.
