Measurement of conversion efficiency of soft X-ray from 0.35μm laser-irradiated aluminum planar targets

Conversion efficiency of soft X-ray from 0.35 μm pulse laser-irradiated aluminium planar target at laser intensities 10¹³–10¹⁵ W/cm² on the Xingguang-II facility (laser energy 5–90 J, focal spot ⊃ Ф 200 μm full width of half maximun (FWHM) 400–800 ps) was measured. A simple model was given to explain soft X-ray conversion efficiency. In this model, because of the heat conduction from the laser-heated spot, the conversion was very small at lower irradiance limit, while at higher limit it was bounded by the energy lost in blow off plasma. Consequently, at the laser intensity around 2×10¹⁴ W/cm², the X-ray conversion efficiency reaches a maximum.

基于B/S结构的教学档案计算机管理系统研究

信息技术的发展给学校教学管理的革新带来了美好的前景。目前基于Web的信息管理系统有两种结构模式:传统的C/S(Client/Server)两层结构模式和最新的B/S(Browser/Server)三层结构模式。本文根据成人教育教学档案管理的特点和要求,探究采用B/S模式的教学管理系统的设计思想和实现方法。     

生活质量:科学发展观的内在要求

人民群众生活质量的提高是科学发展观的内在要求,也是全面建设小康社会不可或缺的方面。人民群众生活质量的稳步与普遍提高,不仅是科学发展观"以人为本"在全面建设小康社会中落实的必然要求,而且也是科学发展观的全面发展、协调发展、可持续发展三者的根本体现,更是科学发展观在经济社会发展实践中必须做到的"五个统筹"的具体落实。     

Screening for hearing loss in early childhood programs

This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed.     

创伤性近侧指间关节屈曲挛缩治疗方法的探讨

目的:对创伤性近侧指间关节挛缩的发病机制和治疗方法进行探讨。方法:对1995～2000年在我院治疗的创伤性近侧指间关节屈曲挛缩病例进行回顾,指间关节挛缩的发病机制,根据关节内外粘连的不同因素进行松解手术治疗。结果:创伤性近侧指间关节屈曲挛缩的病变可分为关节内粘连、关节外粘连及复合性粘连。经过:(1)单纯松解掌板延长及屈指浅肌腱切断等手术。(2)手术加牵引术,取得了良好结果。平均改善关节活动度达100度(屈)(伸)-10度。结论:(1)创伤性近侧指间关节屈曲挛缩的发生与早期处理不当有关。(2)粘连可以是关节内或关节外因素及复合因素造成。(2)手术治疗配合术后牵引治疗可取得良好的效果。
