“大學(xué)物理實(shí)驗(yàn)”是高等工科院校課程體系中一門重要的基礎(chǔ)課程,也是大學(xué)生進(jìn)校后的第一門科學(xué)實(shí)驗(yàn)課程。該課程旨在為后續(xù)專業(yè)實(shí)驗(yàn)和科學(xué)研究奠定基礎(chǔ),不僅要講授學(xué)生開展實(shí)驗(yàn)工作所需具備的基本知識(shí)、基本方法和基本技能,更要培養(yǎng)學(xué)生觀察問題、分析問題和解決問題的科學(xué)思維與創(chuàng)新意識(shí),以及理論聯(lián)系實(shí)際的能力。
隨著國際交流日益頻繁,高等教育國際化是不可扭轉(zhuǎn)的趨勢。為適應(yīng)國際化教育發(fā)展的需要,在西安電子科技大學(xué)物理實(shí)驗(yàn)中心、教務(wù)處和出版社的大力支持下,作者以中文版《物理實(shí)驗(yàn)》(西安電子科技大學(xué)出版社,2007)為基礎(chǔ),結(jié)合多屆外國留學(xué)生的教學(xué)經(jīng)驗(yàn),編寫了本書。本書的編寫已被納入西安電子科技大學(xué)“十三五”規(guī)劃教材建設(shè)。
大學(xué)物理實(shí)驗(yàn)是集體教學(xué)活動(dòng),本書凝結(jié)了物理實(shí)驗(yàn)中心全體教師的集體智慧和辛勤勞動(dòng)。本書編寫過程中得到了許多教師的大力支持,同時(shí)參考了國內(nèi)外其他高等學(xué)校的同類教材,在此一并表示衷心感謝!還要感謝本書的審譯——延安大學(xué)外國語學(xué)院的侯娟娟老師付出的辛勤勞動(dòng)。
實(shí)驗(yàn)教學(xué)探索是永無止境的任務(wù),加之編寫時(shí)間倉促及編者業(yè)務(wù)水平有限,書中難免有不妥與疏漏之處,懇請(qǐng)同行及廣大讀者提出寶貴意見。
