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.

For the structure material, the mode I crack is common and dangerous.
The material parameters are shown in Table. 1.

Optical Properties of Water-soluble Er-doped ZnS Quantum Dots Synthesized by a Hydrothermal Process Gang Li1, a, LiHua Li1,b, LiuShuan Yang1,c , JinLiang Huang1,d 1Department of Material Science and Engineering, Henan University of Science and Technology, Luoyang 471023,China alg337811663@163.com,blilihua7818@163.com,cliushuan@hncj.edu.cn,dhuangjl@haust.edu.cn Keywords: Er-doped ZnS; Quantum dots; hydrothermal process; Luminescence properties Abstract.
QDs are recognized as ideal ultrasensitive, multicolor and multicomponent fluorescent labeled probes due to their bright, photostable and color-tunable fluorescence characteristics.The most vestigated quantum dots (QDs) are usually cadmium-based materials, such as CdSe, CdTe, and CdS QDs [7-9].
ZnS is one of the important II-VI semiconductor materials.
Rare earth complexes became excellent luminescence materials, as lanthanide ions with peculiar characteristics.

Some properties of fatigue crack propagation can be obtained by evaluating the mechanical performance of the material.
With reference to GB/T6398-2000 “Standard test method for fatigue crack growth rates of metallic materials”, plastic fatigue crack growth rate experiments were carried out with compact tension specimens of X70 and X80 pipes in this paper.

The majority of SOFC development to date focuses on electrolyte-supported cells (ESCs), cathode-supported cells (CSCs), or anode-supported cells (ASCs), whose mechanical supports are brittle ceramic or cermet, and contains expensive materials.
Operation of the SOFC at a reduced temperature can overcome some of these problems and bring additional benefits, such as low cost materials, rapid start-up, and low corrosion rate.
