Cultural relics are the real objects to stimulate patriotism and national self-confidence for ust Cultural relics are the material evidences for us to study of history of ancient science.
Some people lacking maintenance experience may arbitrarily change the form, structure and decorate, even replace raw materials of ancient buildings.
First, we should save original basic contents of ancient buildings, namely four contents, including original forms, structures, materials, and technologies of ancient buildings.
About materials, what is the original material, what material should been used to repair.
Authenticity means truly expressing the architectural constitution forms and combining the old and new building materials, and reflecting the original true soul of the regional culture carried by local building in the process of protection updating.

Moreover, the eccentricity reduces the effect of piercing on the capacity of CFST column. 1 Introduction CFST (Concrete Filled Steel Tube) is a combinatorial material using concrete to fill the space inside steel tubes.
The material owns outstandingly improved bearing capacity as the advantages of both concrete and steel can be made good use of due to the combination and has been taken into use in various civil engineering fields and structures.

Specific features of investigations of different interfaces in various materials are considered, such as equilibrium boundaries of recrystallization origin in coarse-grained materials, non-equilibrium boundaries in submicro- and nanocrystalline materials and interlayer boundaries in multilayered structures.
Mössbauer spectroscopy of submicrocrystalline and nanocrystalline materials Various technologies of obtaining submicro- and nanocrystalline materials have been developed in the last decades.
Great problems arise in Mössbauer studies of nanostructured materials.

The accumulative damage model in which the material’s plastic strain is defined as variable and the energy dissipation is also considered is applied to the combined welded heavy steel plates.
The damage model of structure is usually classified into damage constitutive model based on material, damage assessment model based on component and damage assessment model based on structure.
In engineering, damage assessment model based on component or structure has a more extensive application than damage constitutive model based on material.

The beryllium bronze for capacitance sensitive accelerometer Hongwei Wang1,a, Xu Tian2,b 1School of science, Beijing Information Science and Technology University, Beijing100192, China aemail:drhwh@bistu.edu.cn, bemail:just_doit626@163.com, Keywords: accelerometer, capacity, beryllium bronze Abstract.
Based on elastic good for beryllium bronze material making sensitive vibrating components of accelerometer, and developed the capacitance the capacitance sensitive type of accelerometer.
Summary Beryllium bronze is a kind of metal material with good elasticity, It is not easy to fatigue, high density, suitable for inertial vibrating element. and simple process, low processing costs.
So the special material of beryllium bronze is worthy to study inertial sensors.
