In this paper, firstly, two alternative bi-level programming models for the network design problem ( NDP) are established by using reserve capacity concept and total emissions control thought, which can avoid the three emission paradoxes effectively.

本文首先利用备用能力（reserve capacity）概念和尾气污染总量控制思想，建立了两个等价的NDP双层规划模型，该模型能够同时消除这三种尾气污染悖论；

Through close loop control by an oxygen sensor, the actual air-fuel ratio is controlled to the ideal air-fuel ratio and the exhaust emission is reduced by a three unique catalytic converter.

利用氧传感器实现闭环控制，将实际空燃比控制在理论空燃比附近，从而通过三元催化剂控制排放。

Cooking fume is one of the three municipal complaints, and it does great harm to environment and humen health, so its emission control must be imperative under the situation.
