一、引言发电厂和变电所极易遭受雷击以及电气、机械设备故障的危害,也易受人为误操作的危害.在这些危害中,数量级达几千安的冲击电流涌入电厂或从电厂流出。发电厂和变电所对工作人员和设备的保护通常是使冲击电流经接地系统流入地中以防止电荷积累,从而避免第二次故障.注入地中的电流 Ii在故障点必然感生一输入电势Vi=IiRi,其大小决定于接地系统的接地电阻Ri。如果接地系统是由打入地中的单根棒形导体所组成,则地表面的电位将与其到电流注入点的距离成反比。于是故障期间位于接地极附近的

Scattering Performance of a Plane Wave by Conducting Finite Helix

＜正＞ The scattering of a plane wave with a linear polarization by a conducting finite helix is presented. The analytical expresses of scattering field are obtained based on the boundary condition of a sheath helix model. Effects of a pitch angle and electrical size of the helix on the resonant behavior are investigated. The analysis shows that resonant behavior of the forward/backward scattering far field is only depended on the pitch electrical size and the radial electrical size, but it is independent of the turn of the helix.

Genome-wide DNA hypermethylation and homocysteine increase a risk for myopia

AIM: To test for the association between genome-wide methylation and myopia in human and mice. METHODS: Long interspersed nucleotide element 1(LINE-1) methylation levels were used to surrogate genome-wide methylation level. We first tested for the association between high myopia(<-6 D) and LINE-1 methylation in leukocytes in 220 cases and 220 control subjects. Secondly, we validated the results of LINE-1 methylation in eyes from the form deprivation myopia(FDM) mice. Furthermore,we calculated the correlation of LINE-1 methylation levels between leukocyte DNA and ocular DNA in the mice. We also tested whether dopamine can alter LINE-1 methylation levels. RESULTS: The LINE-1 methylation level was significantly higher in the myopic human subjects than controls. The upper and middle tertiles of the methylation levels increased an approximately 2-fold(P≤0.002) risk for myopia than the lower tertile. Similarly, FDM mice had high LINE-1 methylation levels in the leukocyte, retina and sclera, and furthermore the methylation levels detected from these three tissues were significantly correlated. Immunohistochemical staining revealed higher levels of homocysteine and methionine in the rodent myopic eyes than normal eyes. Dopamine treatment to the cells reduced both LINE-1 methylation and DNA methyltransferase levels. CONCLUSION: LINE-1 hypermethylation may be associated with high myopia in human and mice. Homocysteine and methionine are accumulated in myopic eyes, which may provide excess methyl group for genome-wide methylation.

Mini-Review:Green sustainable processes using supercritical fluid carbon dioxide

引用

Journal of Environmental Sciences 2009年第6期21卷 720-726页

作者： RAMSEY edward University of Science and Technology Liaoning

Environmentally benign carbon dioxide offers significant potential in its supercritical fluid phase to replace current reliance on a range of hazardous, relatively expensive and environmentally damaging organic solvents that are used on an extensive global basis. The unique combination of the physical properties of supercritical fluids are being exploited and further researched to continue the development and establishment of high efficiency, compact plant to provide energy and water efficient manufacturing processes. This mini-review is focused on the use and potential applications of supercritical fluid carbon dioxide for a selected range of key and emerging industrial processes as a sustainable alternative to totally eliminate or greatly reduce the requirement of numerous conventional organic solvents. Examples of the industries include： chemical extraction and purification, synthetic chemical reactions including polymerization and inorganic catalytic processes. Biochemical reactions involving enzymes, particle size engineering, textile dyeing and advanced material manufacture provide further illustrations of vital industrial activities where supercritical fluid technology processes are being implemented or developed. Some aspects relating to the economics of sustainable supercritical fluid carbon dioxide processes are also considered.

High-order schemes for predicting computational aeroacoustic propagation with adaptive mesh refinement

引用

Acta Mechanica Sinica 2013年第1期29卷 1-11页

作者： edward Peers Xun Huang State Key Laboratory for Turbulence and Complex Systems Department of Aeronautics and Astronautics College of Engineering Peking University

High-order schemes based on block-structured adaptive mesh refinement method are prepared to solve computational aeroacoustic （CAA） problems with an aim at improving computational efficiency. A number of numerical issues associated with high-order schemes on an adaptively refined mesh, such as stability and accuracy are addressed. Several CAA benchmark problems are used to demonstrate the feasibility and efficiency of the approach.
