Introduction Aerogels have tremendous importance in materials science and engineering, mainly due to their high surface area and variable porosity.
These features are important for heterogeneous catalysis, gas sensing and separation science [1-6].
Unique structural and morphological properties, including open porosity, large pore volume, and excellent temperature stability [7], render aerogels promising materials for catalytic applications [8].
Altering the chemical composition of the aerogel framework to generate catalytically selective high surface area materials is an area of current topical interest.

The research on microscopic failure criterion of masonry Weijun Yang 1, a，Yao Li 1, b ，Ning Jiang2, c 1Changsha University of Science and Technology, Changsha, Hunan, 410114, China； 2 Sichuan College of Education, Chengdu 611130，China； amgbyrh@163.com，byaoyao-1987@163.com，cjl0815@163.com Key word: microscopic, failure criteria, masonry, interface Abstract.
The chief aim of this paper is to set up different masonry dual failure criteria by an effective tool of composite material mechanics and verify it by test data at home and abroad.
The relation between them is found out by CUR in 1994 [3]: Fig.1 Microscopic model of masonry Fig.2 The constitutive relation of brick and mortar ， Where：,,is the elastic and shear modulus of block and mortar;is the thickness of binding surface .The elastic modulus relation of mortar, block and masonry is accord with composite material mixed equation for composite material made by mortar, block and masonry
Conclusion (1)It is put forward a suitable composite failure criterion (eq.15) for microscopic masonry according to the composite material mechanics.
