说明：  abaqus fortran语言下的dload和vdload程序代码，以显示及隐式实现移动加载(Dload and vdload code in ABAQUS FORTRAN to display and implicitly implement mobile loading)

平面波与涡旋光束干涉的干涉图样，可以用来制作全息图，从而产生涡旋光束(Interference pattern of plane wave and vortex beam interference, can be used to produce hologram, resulting in vortex beam)

Do you need to gain confidence with handling numbers and formulae? Do you want a clear, step-by-step guide to the key concepts and principles of statistics? Nearly all aspects of our lives can be subject to statistical analysis. Statistics: An Introduction shows you how to interpret, analyze and present figures. Assuming minimal knowledge of maths and using examples from a wide variety of everyday contexts, this book makes often complex concepts and techniques easy to get to grips with. This new edition has been fully updated. Whether you want to understand the statistics that you are bombarded with every day or are a student or professional coming to statistics from a wide range of disciplines, Statistics: An Introduction covers it all.

很好用的单导线平差，具有单线的计算能力 可以已知两点或者方位角开始计算(Very good adjustment with a single wire, with one-way computing power can be known to start two or azimuth)

采用M语言仿真stribeck的三轴伺服系统，可以在低速情况下观察较强的摩擦现象(With M-language simulation stribeck three-axis servo systems, in the case of low friction phenomena observed strong)
