A triaxial test is an important experimental method for geological materials including coal.
Since the invention of CT (computerized tomography), the inner defects and structures of materials have been detected widely by CT scanning.
Generally, the strength of geological materials agrees with Mohr-Coulomb Criterion that can be expressed as: (1) where C is cohesion, φ friction angle, the maximum principle stress σ1 equals to the compression strength, and the minimum principle stress σ3 equals to the confining pressure.
The white color indicates high-density material and the black indicates low-density material.

Marking and Evaluating Index of Scientific Research Nurturing Teaching in Universities Yang Weijun1,a, Zhang Guijin1,b, Zhang Tingting1,c,Yuan Shuai1,d 1Changsha University of Science & Technology, Changsha, 410076 amgbyrh@163.com, bgizhang98@yahoo.com.cn, c691762880@qq.com, dicetuo81@hotmail.com Keyword: higher education quality; teaching making; evaluation index Abstract: Experts and scholars have debated for the relationship and importance of university researching and teaching for a long time, owing to the problem that classroom teaching is not attached importance exists objectively, and becomes more serious.
New achievement, new theories and new applications of science and technology are emerged in an endless stream, which objectively needs college teachers to stand for the frontier of knowledge development, update and supplement the knowledge to meet the need of cultivating creative talents.
This course involves related mechanical problems of the stable deformation of engineering, seepage, displacement and structure aging, material and so on.

The results show that the Kosteletzkya virginica bast fiber is an appropriate candidate for the new textiles materials which can grow in the brackish portions of coastal tidal marshes.
Experimental section Materials The Kosteletzkya virginica bast fibers (obtained from biotechnology institute of Nanjing University, China), castor-oil plant and cotton fibers (purchased from the market, China), were used for this study.
This was due to removal of amorphous materials like hemicellulose, lignin and some other non-cellulose materials during the degumming process.
As the temperature was increased the mass remained constant until 252 ℃, the temperature which corresponds to the beginning of the thermal degradation (Td), which was due to the thermal depolymerization of non-cellulose materials [20].

The material requirement of the RCC layer may be relaxed, such as adding an appropriate amount of fly ash or using the materials with low-grade cement and local aggregate of non-specification, and the sliding and wearing resistance condition can not be considered so that cost can be reduced.
In view of combined with its material properties, construction process and the actual use conditions and analyzing, calculating its load stress, it is very necessary to optimize the design of this kind of composite pavement structure.
Fiber in the BFRC is three-dimensional random dispersed, with the ordinary concrete as isotropic material properties, so the BFRC above laminates and RCC following laminates are calculated and analyzed as isotropic solid elements.

Effect of kernel moisture content to the result of bare hand threshing of corn ear interval Li Xinping, Du Zhea and Ma Yidong College of agricultural engineering, Henan University of Science and Technology, Luoyang 471003, China aduzhe03@sina.com Key words: corn seed, law, moisture content, bear threshing.
Materials and Methods Preparation of test samples.The test of hand-picked seed corn for Ning Yu 524 which has tend to be hard grain type and conical body and Xun Dan 20 which has dent corn and conical body, moisture content are 19.1% and 19.0%.
(a) Ning Yu 524 （b） Xun Dan 20 Figure 4 Ear on different threshings moisture ,at different intervals ear bear contact force diagram From figure 3,threshing moisture content of ear has a great influence on the contact force of threshing kernel.When the moisture content of ear is 19.0%,kernel properties is similar to the plastic material,the fruit stalk coarsening, enhance toughness, mechanical strength increase,longitudinal and lateral of corn kernels have close squeezing and form a strong support.So the reasons are increasing the threshing force.Moisture content chang the interaction between corn kernels in some extent,but for the fruit stalk strength index,the moisture content of threshing kernel should not be too large.When the moisture content of ear are 16.7% and 13.5%,the contact force needed appear is large,ear kernel arrange most closely,and the kernel is not similar to the brittle materials and plastic
material,arrangement between kernels, fruit stalk,toughness are in normal state.So this moisture content is the most suitable for threshing.When the moisture content of ear is 9.7%,kernel properties is similar to the brittle material,the fruit stalk become thin and brittle,mechanical strength decrease,corn cob and kernel are likely to generate the volume contraction,reduce the squeezing role between kernels until arising gap,so it is easy to loose kernel,the contact force needed of threshing corn kernel decrease and may mutation.And this moisture content is too low, extremely dry, for the storage of moisture content,and kernel in this moisture content not suitable for threshing.
