本书是一本科普书，以讲故事的形式介绍爱因斯坦的生平和狭义相对论的订成果：质能关系、时间延迟和尺子收缩，以及这些结果给人们生活带来的影响。为了照顾学生及一般读者的需求，作者用代数的方法简捷地推导了狭义相对论的基本理论。本书适合对相对论及其发现者有兴趣的读者。

“中国文物与学科”丛书，分为《文物与语文》、《文物与数学》、《文物与物理》、《文物与化学》、《文物与生物》、《文物与历史》、《文物与地理》、《文物与音乐》、《文物与体育》、《文物与美术》共十种。每种在编写地程中要突出学科特点，又不能写成某门学科的历史；要照顾到学科知识，又不能脱离文物资料。文物无声地讲述着过去。学科知识被用来建设现在和未来。可你是否觉得，我们的祖先具有的知识已丰富得让你惊讶？你又是否想像过，我们的祖先如何利用他们的知识创造、改善和丰富生活呢？一切都凝取聚在文物之中。一切都包含在。《中国文物与学科》丛书里。本书以物理学各分支学科为纲，分别叙述与此相关的某些文物，讨论它们可能蕴涵的物理学知识，在物理学史上的价值和意义；或者从历史文献中记述的物理学知识入手，讨论文物反映的认知背景。本书为读者提供了。从物理学方向欣赏文物的一种新视角，以及一种以文物实证治科学史的方法，可供文物、历史和科学工作者参阅。

This text is concerned with a probabilistic approach to image analysis as initiated by U. GRENANDER， D. and S. GEMAN， B.R. HUNT and many others， and developed and popularized by D. and S. GEMAN in a paper from 1984. It formally adopts the Bayesian paradigm and therefore is referred to as "Bayesian Image Analysis". There has been considerable and still growing interest in prior models and， in particular， in discrete Markov random field methods. Whereas image analysis is replete with ad hoc techniques， Bayesian image analysis provides a general framework encompassing various problems from imaging. Among those are such "classical" applications like restoration， edge detection， texture discrimination， motion analysis and tomographic reconstruction. The subject is rapidly developing and in the near future is likely to deal with high-level applications like object recognition. Fascinating experiments by Y. CHOW，U. GRENANDER and D.M. KEENAN（1987）， （1990） strongly support this belief.本书为英文版。

以往电大的力学教材，包括一些专科学校的力学教材，基本上以本科力课程教材为蓝本，加以压缩。过于追求理论的系统性和体系的严密性；各门力学课程（例如理论力学、材料力学和结构力学）自成一体，互相隔离，形成重叠；要求偏高，内容偏深，习题偏多；忽视人成人教育的对象，地于偏重讲授，注重用不够。本书包括了以下内容：1.轴向拉伸实验，圆轴扭转实验，梁弯曲实验（实验预习，预习自检，仿真实验，实验结果分析，实验录像，资料柜）；2.课程的重点难点分析；3.教你做题；4.考考你。为了形成成人高等教育力学教材的新体系，笔者认为必要将原属理论力学和材料力学两门课程的相关内容加以贯通、融合和渗透。以常规工程设计的需求安排教学内容，形成工程静力分析、基本我件的弹性静力分析、工程运动分析与动力分析的体系，力图体现“工程应用”的目的。

THE first edition of this book appeared more than thirty years ago. in the course of reissues over these decades the book has been revised and expanded; its volume has almost doubled since the first edition. But at no time has there been any need to change the method proposed by Landau for developing the theory， or his style of presentation， whose main feature was a striving for clarity and simplicity. I have made every effort to preserve this style in 'the revisions that I have had to make on my own. As compared with the preceding edition， the first nine chapters， devoted to electrodynamics， have remained almost without changes. The chapters concerning the theory of the gravitational field have been revised and expanded. The material in this. e chapters has increased from edition to edition， and it was finally necessary to redistribute and rearrange it.　本书为英文版。

TWENTY-FIVE years have passed since the writing of this volume in its first edition.Such a long interval has inevitably made necessary a fairly thorough revision and expansion of the book for its second edition. The original choice of material was such that， with some very slight exceptions， it has not become obsolete.In this part， only some relatively minor additions and improvements have been made.本书为英文版。

THE previous edition of this volume was the last book on which I worked together with my teacher L. D. Landau. The revision and expansion that we then carried out was very considerable， and affected every chapter. For the third edition， naturally， much less revision was needed. Nevertheless， a fair amount of new material has been added， including some more problems， and relating both to recent research and to earlier results that have now become of greater significance.此书为英文版。
