In Part 1, Electrical Resistance Strain Gauges, Chalmers discusses present day materials and construction methods for gauges and their performance characteristics. Mordan describes the various adhesives used and the installation methods for a wide variety of applications and performance requirements. This subject is taken further by Pople to cover the particular problems of installation and protection in difficult and hostile environments. Scott and Owens discuss strain gauge instrumentation at length, reviewing the well known and tranditional equipment, but adding a powerful introduction to computerised data acquisition and reduction, and to the trends towards high speed digital systems. Part 1 is concluded with a unique exposition on error analysis which should give every strain gauge practitioner cause for thought. 

在本书第一部分《电阻应变仪》中，查默斯讨论了目前应变仪的制造材料、制作方法及其性能特点。莫丹叙述了所用的各种粘接剂和在各种应用与性能要求条件下的安装方法。波普尔则对这个问题作了进一步的论述，阐明了在困难和不利环境中，应变仪的装配与保护等特殊问题。斯科特和欧文斯详细讨论了应变仪的仪器仪表配置，虽只对大家熟悉的传统设备，但接着又对计算机化数据采集与处理以及向高遍数字系统发展的趋势等作了权威性的介绍。第一部分以关于误差分析的独到说明来结束，这是每个从事应变仪工作的专业人员必须思考的问题。

Part 2 covers three very important though not so widely used strain gauge groups. Baker introduces and updates the performance characteristics of semiconductor or piezo resistive strain gauges. Procter and Strong review the available capacitance strain gauges, increasingly used for static strain measurement at elevated temperature, and Hornby describes and discusses applications of vibrating wire strain gauges which are particularly well suited to measuring long-term static strains in civil engineering. 

第二部分论述了三种应用不那么广泛但却非常重要的应变仪。贝克介绍了半导体即压阻应变仪的性能特点，以及不断对其进行改进的情况。普罗克特和斯特朗对现有的电容应变仪作了评述，这类应变仪在高温环境静态应变测量中应用日益广泛；而霍恩比则叙述并讨论了振动丝应变仪的应用情况，这种应变仪特别适合于测量土建工程中的长期静态应变。

This book is intended to fill an important gap between the manufacturers' literature which gives detailed instructions for handling a particular product, and a text book which covers basic theory and general principles of strain measurement. It brings together much needed practical "know-how" and experience from a number of leading exponents of the various aspects of strain gauge practice. All the authors are practising engineers in the real commercial world, and whilst some are well known for their published work, others have been persuaded for the first time to commit their knowledge and experience to paper. It is hoped that the result will prove equally useful to both "do-ers" and "specify-ers". 

本书是用来填补制造厂家对运用某一特定产品的详细说明与叙述应变测量基本理论、一般原理的教科书之间的巨大空白的。本书把人们迫切需要的实用专门技能和从应变仪应用实践中大量典型实例上的经验汇集在一起。本书的所有作者都是现实商品世界里的创业工程师，其中一些人因出版过著作而闻名于世，其他人则是首次被说服把自己的学识和经验写下来奉献给读者。希望这一成果不论对于“实于家”还是对于“制定规范的人”都同样有价值。
