查询词典 keep sb. at a distance

This simulation shows that a capillary tube with thin wall should be used in experiment and the fringe pattern is very sensitive to the distance between the cylindrical lens and the capillary tube. For enhancing accuracy, this distance should be determined by fitting a standard liquid with known refractive index in experiment.

结果表明实验中应使用薄壁毛细管，由于干涉条纹对柱面透镜到毛细管之间的距离非常敏感，为提高精度，建议在实验中用已知折射率的标样来确定这一距离。

He has been active in describing and interpreting distance education since 1965 for purely academic reasons, first at the Educational Centre inBerlin, then at the German Institute for Distance Education Research and then as Professor of Didactics in Berlin.

自1965年起，彼得斯教授先后在柏林教育中心、德国远程教育研究所工作，1975年至1985年，在德国哈根远程教育大学担任首任副校长，在此之后，他专门从事远程教育研究工作。

The features of this dissertation are lie in: a The concept of"Influence Distance"was presented to quantitatively express"corner effect", systematicly studied on the influence of all factors on"influence distance". It could provide reference to angle designing from the view of heat treatment; b Deeply studied on the influence of shape factor to carbon concentration field. It could provide reference to gear designing from the view of heat treatment; c New model was set up to describe the two-dimensional concentration field of carbide dispersion carburizing. The shortcomings of"effective diffusion constant method"and"equilibrium constant method"were overcome in this model.

本文的特色在于：①提出了用"尖角影响距离"定量描述"尖角效应"的方法，并系统研究了各种因素对"尖角影响距离"的影响规律，从热处理角度为工件尖角部位的设计提供依据；②首次深入研究了齿轮的各种形状因素对浓度场的影响，从热处理角度为齿轮设计提供依据；③建立了能够更有效地模拟过饱和渗碳浓度场的数学模型，该模型克服了"有效扩散系数法"及"平衡常数法"的不足，与"最小自由能法"可互为补充。
