Study on Emission Characteristics of Automobile Exhaust and Control Measures with Environmental Materials* YANG Jin-xiang, LI Xiao-long The School of Earth and Environmental, Anhui University of Science and Technology, Huainan Anhui, 232001, China xlli@aust.edu.cn Keywords: automobile exhaust, emission characteristics, environmental materials Abstract: With the rapid development of automobile industry and the accelerated process of urbanization, pollution caused by automobile exhaust had become one of the major sources of urban environment and atmospheric environment pollution.
And the pollutants emitted by automobile into the air with rain felled into the ocean to cause great damages to marine environment. 2 The control of automobile exhaust with environmental materials 80% to 90% of the global urban emissions were from motor vehicle emissions.

An adhesive composition is used as a binder in many composite materials.
Crack resistance of an adhesive composition is the most important characteristic determining the bearing capacity of composite materials.
Introduction An adhesive composition (joint) is used as a binder in many composite materials.
One of the most important characteristics determining the bearing capacity of composite materials is a crack resistance of an adhesive composition.

It indicated that this method can be used to design not only SiC/Ti(C,N)/Al2O3 ceramic die material but also other ceramic materials.
So the experiment times will be reduced, and the efficiency of materials design will be improved.
