Abstract: |
This paper has put forward the definition of L distribution, worked out its mathematic expectation and variance, presented, with spots of maximum curvature, the stage division of the growth process discribed with L distribution, and fitted the ecdosion process of crop pests with L distribution as well. |
Key words: L distribution,variance, sport of maximum curvature,stage division |
