The failure of the whole honeycomb sandwich composites are judged by the failure criteria of constituent materials.
Then the stresses in the constitutent fiber and resin materials can be determined through the bridging matrix, ,
Due to the same reason, the ultimate load predicted by this paper is 17.3% higher than testing results which is acceptable in engineering.

The engineering geologic and hydrogeololgy conditions are extremely complicated.
At the same time, the given membership is shown in Tab.1 referring to engineering geological analogy method and combining index factors of the studying region.
This method has good engineering and academic significance in karst area tunnel water bursting geological disaster risk evaluation.
In practical work, the results got from engineering geological analogy method and analytic hierarchy process can verify mutually in order to supply reference for tunnel design and construction in Karst region.
Study on Geologic Analytical Means on Karst Advanced Forecasting of Tunnel Engineering on Yichang-Wanzhou Railway.

Study on Repairing Motherboard with Fuzzy Reasoning Yang Hui1,a Wu Ru-bin1,b Liu Jun1,2 ,c Cai Qiong1,d (1.School of Computer Science and Engineering, Wuhan Institute of Technology, Wuhan 430074, China) (2.Hubei Province Key Laboratory of Intelligent Robot, Wuhan 430074, China) a:yyaanng@yeah.net b:sqlwrb@163.com c: lorime@126.com d:cai_qong@163.com Keywords: comments sets, fuzzy reasoning, complex motherboard repair, reasoning model, fault model Abstract: On the basis of comments sets of fuzzy reasoning, fault model and the characteristics of complex motherboard repair, fault model is introduced to diagnosis the motherboard and comments sets is used to reflect the priori knowledge.
In addition, it has the following rules according to the maintenance engineers’ experience.
By using the way of experts comment set, according to three kinds of engineers’ assessment (r&d engineers, product engineers, maintenance engineer) for the important degree (divided into: very important, important, general important, general)of four types of chip (North Bridge, South Bridge, high-speed equipment, PCI chip equipment chip),we can get a evaluation table as show in table 1.
On one hand, the expert fault diagnosis model is good for maintenance engineers to narrow the range of faults; While the fuzzy rules and prior knowledge is helpful for engineers to improve work efficiency and reduce the loss of raw materials.

The research from International Data Corporation (IDC) shows that the data amount that the global produced in 2009 is 0.8ZB,and it increased to 1.2 ZB in 2010, what’s more, it reached up to 1.82 ZB in 2011, but by 2012, the data amounts of all printed material humans generated was only 200PB.
The Obama administration also announced "big data research and development plan" in March 2012, and declared that it would invest 200 million dollars pulling the industrial development related to big data, aimed at improving the capacity of the people to get knowledge from the huge amounts of data available, thus accelerating the United States’ pace of invention in science and engineering to strengthen national security.
It achieves the traffic management become a "points to points, key to key, zero distance, and unclocked" service.

Desulfurization of Simulated Coking Benzene on Modified Activated Clay Chunguang Pan, Hongzhu Ma* Institute of Energy Chemistry, School of Chemistry and Chemical Engineering, Shaanxi Normal University, Xi'an, China, 710062 E-mail address: hzmachem@snnu.edu.cn (H.
An effective catalyst is the key of alkylation transfer desulfurization, and the activity of acidic catalyst in the alkylation reaction mainly depends on its strength of superacidity [11].
The activated clay, which is quite abundant in the earth’s upper crust, is an important and cheap raw material for manufacturing such as adsorbents [15] and catalysts[16].
So the key step for improving the catalytic activity was enhanced the acidity of the activated clay.
