The turning point in 1985. The history of appraisal and disposal of records in Iceland

The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described.     

新型工具电极制造方法

用电火花加工复杂形状模腔的关键之一是工具电极的制造。为了解决一般电极材料价高、复杂型腔难以加工等问题,通过试验研究,推出了一种以石膏和塑料为基本材料,采用非金属电镀工艺制造工具电极的新方法。     

综合消除运动疲劳措施效果的初步观察

为解决优秀青少年运动员科学训练问题,对综合消除运动疲劳措施的效果进行了研究。31名受试者采用综合消除疲劳措施(健身按摩椅、带式按摩机、水负离子发生器及音乐等),于训练后放松平均252±10.2min。结果表明:综合消除疲劳措施有使小腿肌肉硬度下降、血流改善、中枢神经系统及神经肌肉功能改善等效果。经对3名重点队员追踪观察2周表明,在运动量相对较大的训练周中,身体机能恢复较好。     

BIODEX在大腿、膝关节伤后功能诊断及康复中的应用

42名有大腿前、后群肌肉拉伤或膝关节急、慢性损伤史的运动员为受试者。用BIODEX 多关节等速测力及康复系统测定膝关节屈、伸肌群肌力,取60(°)/s 向心、离心及240(°)/s 向心收缩的最大力矩(PT)等指标,用“评价表格”进行分析评定,并对力矩曲线加以分析。初步认为,力矩曲线异常具有功能诊断参考价值,并可用于选拔运动员时及时发现伤情。参照BIODEX 测试结果,有针对性的进行康复锻炼,可收到良好效果。
