产品生命周期曲线-
运用皮尔曲线来拟合创新产品的生命周期钟形曲线，建立产品创新最佳周期选择模型并确定出最佳周期及最佳性能，从而解决了这种两难困境。
Using pear cure to imitate the innovated product life cycle curve , an optimal-cycle-selected model for product innovation is set up to calculate the optimal cycle for developing and the optimal capacity of the innovated product , and thus the dilemma is resolved .

提出了裙带度的概念，融入了经济学中的产品或技术生命周期曲线、时间序列原理等方法，为系统的研究打下了理论基础；
The conception of relative degree is proposed in the theory , which involves some methods in economics , such as the lifecycle curve of product or technology and the principle of time sequence , and so on . So the foundation for researching the system is built .
