| Abstract: |
| This paper analyses and compares available calculating models of 3D grain burning surface, discusses a new kind of technique──3-D solid modeling method. The calculation of a star and a finocyl grain was performed, the results show that this method is accurate, generalled, easy-of- use and rich in output information, it is suitable in engineering applications. |
