As the theoretic foundation of low power, power optimization from design levels of digital circuit has been discussed with emphasis based on the basic power consumptionequation.
作为低功耗设计的理论基础，本文从数字电路的基本功耗方程出发，重点讨论了各设计层次优化功耗的方法；

The oxygen consumptionequation which is used for end point control is a proportional model or a multiple variates regression equation established by the stepwise regression method.
控制终点的氧耗方程建了比例型模型和多元回归方程，多元回归方程是按逐步回归建立的。

Start with consumption, the side of the equation that can be forecast with some accuracy.
