Research on Tomography by Using Seismic Reflection Wave in Laneway

AbstractAs a necessary step and an integral part of works in laneway, the geological prediction is an important means of reducing disaster losses and geological disasters in the works in laneway. This paper mainly discusses tunnel reflection tomography by using seismic reflection wave in laneway. The speed of elastic wave in front of tunnel face and the three-dimensional images can be figured out when the detector check the reflection of elastic wave from the focal points on the tunnel face. The location, size and depth of cave can be ascertained. According to the forecasts of laneway works in the Iron Mine Xishimen, tunnel reflection tomography by using seismic reflection wave can well forecast engineering geology and hydro-geological conditions in front of tunnel face. It will help to supply positive guidance for working plan and construction measures in laneway. Therefore, the construction safety and speed can be ensured, helping to lead to great practical significance and significant economic benefits

Transverse momentum resummation for color sextet and antitriplet scalar production at the LHC

We study the factorization and resummation of the transverse momentum spectrum of the color sextet and antitriplet scalars produced at the LHC based on soft-collinear effective theory. Compared to Z boson and Higgs production, a soft function is required to account for the soft gluon emission from the final-state colored scalar. The soft function is calculated at the next-to-leading order, and the resummation is performed at the approximate next-to-next-to-leading logarithmic accuracy. The non-perturbative effects and PDF uncertainties are also discussed.Comment: 20 pages, 7 figure

The Innovation of Poor College Students’ Subsidization Modes in China

In China, poor college students have difficulties not only in finishing high education but also in looking for jobs. Under the current subsidization mode, we focus on helping students finish college, but ignore cultivating their employability. Therefore, we need a new subsidization mode we call developmental subsidization mode with the purpose of improving their competitiveness in the job market. Under this new mode, we provide part-time job opportunities instead of giving students money. Furthermore, new managing mechanisms should be adopted to operate the new mode, its specific strategies including organization management, colleges and enterprise’ collaboration, using good models’ influence and so on. Keywords: Subsidization Mode; Innovation; Poor College Students; China

Research of Construction of Sci-tech Innovation Platform in Anhui Province in China

In the age featured with Big Data, Anhui Province has made great progress in scientific and technological innovation. As a result, there appear new features and new requests of sci-tech management. This article, from the perspective of Big Data, basing on the realistic condition of sci-tech innovation platform’s construction in Anhui province in China, has discussed how to build a better platform. We has creatively proposed the construction principle, which is three-elements-driving (Big Data, Internet of Things and Cloud Computing) and the four-in-one constructing subjects of system and mechanism, innovative service, industry cultivation and technology research and development, and has provided strategic suggestions on how to guarantee the platform’s smooth running from three respects of system and mechanism, fund source and environment. At last, it has analyzed and studied the platform’s effective operation. Key words: Big Data, Anhui Province, sci-tech innovation platfor
