对校园体育文化建设的研究

随着新课改的深入发展,"健康第一"的指导思想在校园体育文化中越发突显出来。校园体育文化是在学校这一特定环境范围内,由学校的师生员工们经过长期教学实践活动共同培养形成的。校园体育文化是营造学校人文气息和文化氛围重要的且不可缺少的内容,可以说是推动校园文化发展的最有力的催化剂。校园体育文化不仅具有丰富的体育知识,修身养性,传播健康方法,营造健康向上、积极活泼的校园文化氛围,给学生搭建了充分展示才华和特长的平台。更重要的是,能通过丰富多彩的活动,培养学生的组织能力,增强学生的参与意识,促进学生人格的完善和情感态度价值观的形成,提高学生的品德修养。对学生的身心健康将起到非常积极的作用。另外,校园体育文化在学校教育中具有举足轻重的作用,对于一所学校的建设和发展具有深远的历史意义和重大的现实意义。     

Measurements of Boundary Plasma in Synergy Discharges of IBW and LHCD on the HT-7 Tokamak

By applying ion Bernstein wave (IBW) heating into the lower hybrid current drive (LHCD) plasma, improved confinements have been obtained in the HT-7 tokamak. The central electron temperature was doubled and the storage energy was increased significantly. The core electron density and temperature were broadened and ther profiles near the edge were steepened. A transport barrier has been formed in the vicinity of the limlter radial location. An enhanced shear in poloidal phase velocity was found in the same region with reduction of the fluctuation levels and the coherences between fluctuations. The results suggest that the improved confinement in the IBW and LHCD plasma is at least partially due to the modification of shear in poloidal velocity and then the suppression of fluctuations and fluctuation induced fluxes via de-correlation effect.     

Time—Resolved Photoluminescence Studies of AlInGaN Alloys

We study the two samples of AlInGaN,i.e.,1-μm Gan grown at 1030℃ on the buffer and followed by a 0.6μm-thick epilayer of AlInGaN under the low pressure of 76 Torr and the AlInGaN layer deposited diectly on the buffer layer without the high-temperature GaN layer,by temperature-dependent photoluminescence(PL) spectroscopy and picosecond time-resolved photoluminescence(TRPL) spectroscopy.The TRPL signals of both the samples were fitted well as a stretched exponential decay at all temperatures,indicating significant disorder in the material.We attribute the disorder to nanoscale quantum dots or discs of high indium concentration.Temperature dependence of dispersive exponent β shows that the stretched exponential decay of the two samples comes from dfferent mechanisms.The different depths of the localization potential account for the difference,which is illustrated by the results of temperature dependence of radiative recombination lifetime and PL peak energy.
