Material levels Material durability research mainly start from factors that influencing the durability of structure, and analyzes the failure mechanism under the action of single factor or more factors, to establish the durability damage prediction model and empirical formula, realize process from the qualitative analysis to quantitative analysis.
Structural concrete permeability of nondestructive testing Permeability is one of the basic properties of porous materials; it reflects the material internal pore size, quantity, distribution and connectivity and so on.
Meanwhile it is necessary from basic theory to study the impact of the durability of the essential reason, cement - water cementations materials is an imbalance, open dissipative system and various compositions formed various micro-structure and pore structure of network systems, material movement follow in the thermodynamics of non-equilibrium state and non-homogeneous process dynamics basic theory, changes in the composition of the substance and structure are essential characteristic parameters of the material characterization durability decay, need to study from the relationship between the two.

From a perspective of life cycle, the research period spans from the extraction of raw materials needed for bridges to their final demolition when all kinds of wastes are treated or recycled.
From an ecosystem point of view, bridge processes like a kind of life metabolism can be demonstrated with fluxes of exchanges of materials and energy between infrastructure system and its surroundings.

The coupling of sp-d electron magnetic of ZnO doped with Mn, Co, Ni, Cu has been studied by MCD (magnetic circular dichroism) method[8] and ferromagnetism of these materials was verified.
Therefore, the ferromagnetism of some materials is questionable[4,16-23] and ferromagnetism even was not found in some doped materials[24,25].
Metal ion deposit or second phase oxides, such as nanocrystal deposit of Co or Ni, may generate during the preparation, which have an effect on the ferromagnetism of materials.
