New materials in nuclear fusion reactor Fusion candidate structural materials mainly include the austenitic stainless steel (represented as the first candidate materials, e.g., PCA material), ferritic/martensitic steel (e.g., HT-9), vanadium alloy (e.g., VCrTi), and SiC/SiC composite materials.
Summary With the further development of materials science and nuclear technology, new material plays a more and more important role in the new nuclear reactor, the ultrahigh temperature, strong radiation, and strong corrosion service environments in new nuclear reactor require higher performance of the new material, now there is no material completely meet the requirements, the researchers need to do further work to solve some common problems in materials, such as the high temperature strength, creep resistance, irradiation damage resistance and corrosion resistance, etc., so as to develop new materials with excellent comprehensive properties.

This paper puts forward some corresponding countermeasures and suggestions on making reform on institutional level and the innovation of financial products to support the development of wood carbon sequestration materials industry, based on the financing obstacles to the development of wood carbon sequestration materials industry, form the significance of wood carbon sequestration materials development. 1.
The Development Status of Wood Carbon Sequestration Materials Industry Wood carbon materials sequestration should belong to sub-sectors of the environmental protection industry for its ecological environment protection effect.
However, wood carbon sequestration materials industry is still in the embryonic stage in forestry. 4.
Barriers of the Wood Carbon Sequestration Materials Industry 4.1 Capital costs are too high The capital cost of wood carbon sequestration materials in financing is including the planting costs, transaction costs and the opportunity costs.

Damage Analysis for Quasi-Birttle Materials of CT Image under Uniaxial Compression Cheng Yi 1, a, Hongguang Zhu 2, b, Lizhen Liu 3, c 1, 2, 3 State Key Laboratory of Coal Resources and Safe Mining, CUMT, Beijing, China, 100083 ayicheng312@tom.com.cn, buu_gr@qq.com, c 360268617@qq.com Keywords: Damage ; CT(Computerized Tomography); Rd index; quasi-brittle; materials Abstract.
In the damage research before on the CT image of quasi-brittle materials such as concrete, the damage evolution is often described by the change of average CT values or image threshold segmentation method.
But for the brittle materials, it is difficulty to distinguish the internal damage from the CT information before macro-cracks appear.
