RESEARCH ON EFFECTIVE RESISTIVITY DEFINED BY THE FIELDS INDUCED BY VERTICAL MAGNETIC DIPOLE The definition of effective resistivity used in electromagnetic sounding induced by hori-zontal electric dipole on layered earth and its algorithms was discussed. 垂直磁偶源频率测深中场分量等效电阻率的研究讨论了水平电偶极子源的各场分量等效电阻率的定义及其迭代算法。
Time series of vertical displacements obtained from continuous GPS observation at fiducial stations in Crustal Movement Observation Network of China, from September 1999 to March 2004 are introduced with discussions on the selection of datum definition and analysis of the general characteristics of vertical displacements at fiducial stations. 利用1998年9月至2004年3月上旬中国地壳运动观测网络基准站GPS连续观测结果所获得的垂直位移时间序列,讨论了基准的选择,分析了基准站垂直位移的特点。
While some turn to the relative determinacy with the help of geometry, and focus on the planes, ignoring the key vertical elements that play definite role of space definition and enclosure. 或者是转而求助于几何学的相对确定性,专注于平面的图案形式,忽视了在空间中真正起到明确的围合与限定作用的垂直要素。
Machining of free form surfaces with CAD/ CAM systems on three axis vertical NC mill requires the definition of CAM parameters. In this paper a method will be proposed for choosing the CAM parameters by the links between CAM parameters and geometrical specifications. 用CAD/CAM系统在3轴立式数控铣床上加工自由曲面,需要确定CAM参数-本文根据CAM参数与零件几何要求之间的联系,确定了一种选则CAM参数的方法-
At first, based on analyzing anti-monopoly law and scholars 'definition of the vertical monopoly agreements, I give a definition to it. 本章首先在分析我国反垄断法和学者对纵向垄断协议界定的基础上得出了纵向垄断协议的定义。
