《润滑数值计算：方法与程序（英文版）》针对Reynolds方程、能量方程和弹性变形方程结合计算方法介绍实用计算程序。前9章主要介绍了不同工况下的Reynolds方程的数值计算与程序，如：滑块不可压稳态润滑、径向滑动轴承润滑、动载轴承润滑、气体润滑和脂润滑等数值计算方法与程序。第10、11章结合能量方程的求解介绍了热流体润滑的数值计算方法与程序。第12～20章主要介绍了弹流润滑数值计算与程序，方法是通过对弹性变形方程的计算，结合与Reynolds方程以及能量方程的联立求解能量方程等考虑等温、热和脂润滑弹流润滑计算的方法和程序。第21～24章介绍了作者针对工程润滑问题开发的一些程序，包括：微型电机人字沟轴承润滑计算程序及其优化设计、磁盘磁头薄膜气体稳态润滑计算及优化设计程序。
《润滑数值计算：方法与程序（英文版）》可供高等学校的相关专业的教师、硕士生、博士生，以及工程技术人员和科研人员使用。

However，mostbooksontribologymainlyintroducetheoriesorcalculationmethodsoflubrication.Theyrarelygiveanddiscussnumericalcalculationprograms.
Notonlyisthisinconvenientforresearchortheproductionofpracticallubrication，butalsomanysimilarprogrammingtaskshavetobecarriedoutrepeatedly.Furthermore，becauseofthelimitationsoflubricationtheory，somenumericalcalculationprogramsmaygivemistakensolutions，leadingtowrongconclusions.
Thisbookisdifferentfromprevioustheoreticalbooksormonographsonlubrica-tion;itmainlyintroducesthenumericalcalculationprogramsoflubrication，Thisisthemainfeatureofthebook.Someoftheprogramshavebeenusedformanyyearsinlubricationcalculationsandresearchbytheauthor.
Duetothecomplexityoflubricationproblems，thebookmainlyfocusesonhowtonumericallysolvetheReynoldsequation，energyequation，elasticdeformationequationandtheircombinations.Theanalyzedlubricationproblemsincludeline，surfaceandpointcontacts，whichcorrespondtothrustbearings，journalbearingsandrollingcontactbearings.Furthermore，theworkingconditionsincludeincompressible，compressible，nonthermal，thermal，isoviscosity，variableviscosity，Newtonianfluid，non-Newtonianfluid（onlygrease），rigidandelasticdeformationsituations.
Thebookisdividedintofourparts，covering24chapters:
Thefirstpart（Chapters1-9）isaboutthesolutionoftheReynoldsequation，whichisthebasictechniqueforthenumericalanalysisoflubrication.ThecontentsincludetheboundaryandconnectionconditionsoftheReynoldsequation，discretizingtheReynoldsequation，numericalmethodsandprogramsofsliderlubrication，numericalmethodsandprogramsofjournalbearinglubrication，numericalmethodsandprogramsofdynamicbearinglubrication，numericalmethodsandprogramsofgaslubrication（especialmagneticharddiskhead）andsoon.lnthispart，wealsodiscussthetheologyoflubricants.Asanexample，greaselubricationisdiscussed，whichisakindofnon-Newtonianfluid.
