Study on the Preparation Conditions of Nano-silver Substrate Used for SERS Determination of Thiophene Zongting Wanga *, Junjie Zhangb, Lijun Zhouc, Xiaowen Pei and Fengying Wang Department of Chemistry, College of Science, China University of Petroleum(East China), No.66, Changjiang West Road, Huangdao District, Qingdao,266555,China aztiwang@upc.edu.cn, bzhangjunjie0324@126.com, czhoulijun0796@163.com Keywords: Potentiostatic oxidation-reduction method; KBr; Nano-silver substrate; Thiophene; SERS Abstract.
Although there was certain enhancement effect with the increasing of KBr concentration, the bond strength of nano-material declined and it was easy to fall off from silver surface when be ultrasonic cleaned.

Local weak support effect on the stability of surrounding rocks in deep roadway Weijun Hu 1, a, Hua Cheng 2, b 1Graduate student, School of Civil Engineering and Architecture, Anhui University of Science and Technology, Huainan, Anhui P.R.
In this roadway, the section deformation phenomenon serious, the old repair plan is only by strengthening the roof support, for the floor just weak support or none support, often repaired and often bad, spent a lot of financial and material resources, but also seriously affect the safe production of the enterprise.

A special attention in this field over the last years has been focused on the formation of directional morphologies that can be obtained during directional solidification or directional annealing of metallic materials [1-4].
According to numerous authors, the columnar morphologies have considerable effect on mechanical properties of materials [6, 7].
The peak temperature was naturally limited, since it could not exceed the melting point of the material.
