阿贝(Abbe)原则是进行长度测量的指导性原则。它指出:若要得到正确的测量结果,必须将仪器的读教刻度尺放在被测尺寸线的延长线上.根据此原则,制造了阿贝比长仪,进行绝对测量.一般测长仪器的测量值,可用下式表示式中S为刻度尺到被测物的垂直距离,,△θ为量爪的角位移.如图1所示,可见误差由S和△θ这两个因素引出.阿贝原则恰能使S=0. 由于阿贝原则难于应用于一般测量仪器,故布莱恩建议修改阿贝原则:位移测量系统工作点的路程应和被测位移作用点的路程位于一条直线上;或者必须使传送位移的导轨没有角运动,或者必须用实际角运动的数据计算偏移… 相似文献

I review the scientific production of Eberhard K.U. Gross (Hardy Gross) in the first 25 years of his scientific career, from his study time at the Goethe University in Frankfurt am Main to the time he moved to the Free University of Berlin, as Full Professor. In between there was a fruitful period, in which he worked at the University of California, Santa Barbara, with Walter Kohn, the “father” of Density Functional Theory (DFT). DFT has been the permanent tool of Hardy Gross research. His main achievement in the considered period is the proof of an existence theorem for the Time-Dependent Density Functional (TDDFT) and the search for application schemes in atoms, molecules and solids, starting with linear response. He made notable contributions to the application of DFT and TDDFT to superconductors, in static and dynamic cases. 相似文献
