Effects of the different organic materials on the structure and elemental composition of humus in black soil Jianming Li1,a, Jinggui Wu1,b 1College of Resource and Environment Science, Jilin Agricultural University, China 130118 aljmok1986@hotmail.com, bjgwu68@sohu.com(corresponding author) Key Words: Structure, Elemental composition, Humic substance, Organic material Abstract.
Apart from animal excrement, others organic materials significantly increased N content of HA.
Among different organic materials, only herb residues increased N of FA.
All of the organic materials significantly increased O content of HMi, and apart from herb residues, the N content of HMi in others organic materials were also significantly increased.

This paper fulfils identified information about materials and heat transfer properties of materials and manufacturing challenges of these three solar thermal collectors.
Many surveys and reports have been carried out on polymers as solar collector materials [8].
Thin-walled cellular polycarbonate materials in the form of transparent capillary structures or square honeycombs are being employed extensively as collector glazing materials [9].

The Preparation of ZnO Gas-sensing Material by Nucleation- Crystallization Separation Method Xiu-Tao Ge 1,a, Jun-hai Wang 1,b， Ding Wang 2,c and Jia-qiang Xu 2,d 1Department of Chemistry and Life Science, Chuzhou University, Chuzhou 239012,China 2Department of Chemistry, College of Science, Shanghai University, Shanghai 200444,China aemail, gext59228@126.com, bemail, wjh166@163.com, cemail, Wangding@shu.edu.cn, demail, xujiaqiang@shu.edu.cn Keywords: Nucleation-Crystallization Separation; ZnO nanoparticles; Gas-sensing materials Abstract.
ZnO nanoparticle, a new state of ZnO, has a broad application prospects in high-tech industry, such as in optical materials, gas-sensing materials, electrode materials, active catalysis, magnetic materials, sterilizing materials and etc [6-9].
Therefore, it not only broadens the range of applications of the nucleation-crystallization in materials synthesis, but also provides a new way improving the performance of ZnO gas sensors and functional materials for industrial production.

By comprehensive contrast of the wear resistance of hardening materials, relative wear resistance of composite iron plating is better than common engine cylinder material, and can fit for the cylinder hardening of high load engine.
The wear resistance of composite iron plating is higher than the other two materials not only at the low and middle but also at the high load.
Then the wear rules of hardening materials are studied.
