| Abstract: |
| The author consides a multimolecules model ẋ=W-ax-xpyq,ẏ=xpyq-by where x ≥ 0,y ≥ 0;W,a,b,p and q are positive constants.Under the conditions that the concrete expression of its singularities are not sloved,we discuss the bounded property of trajectories,separatrix configuration,nonexistence and existence of limit cycle. |
| Key words: separatrix limit cycle phase diagram |
