摘 要:測定冰溶解熱的實驗持續(xù)時間短、溫度變化快，通過水銀溫度計很難在較短時間內(nèi)快速準確地完成多次測量。由此設計出一種測量冰溶解熱的“數(shù)字實驗”：利用自動溫度采集系統(tǒng)測量出實驗溫度，通過用Visual Basic開發(fā)的實驗系統(tǒng)軟件對溫度數(shù)據(jù)進行計算和散熱修正，可以快速準確地完成實驗，以及直觀地顯示出測量結果?！?/p> 關鍵詞：熔解熱；數(shù)字實驗；溫度采集；實驗軟件
ABSTRACT:The experiment of measuring ice’s heat of solution always lasts for a short period and the temperature changes quickly. It is difficult to finish some measurements quickly and accurately in a short time with the Mercury thermometers. Considering these disadvantages, a " digital experiment " was designed to measures ice’s heat of solution.The collection system of automatic temperature was applied to measure the experiment temperature.And the experiment data was calculated by a software of experiment system which was developed with the Visual Basic software. Then we can finish the experiment quickly and accurately, and show the result of measurement directly. Keywords: Heat of solution; Digital experiment; Temperature collection; Experiment software
隨著社會的發(fā)展數(shù)字實驗也越來越受到人們的關注和重視，如現(xiàn)在很多高校都正在建設以數(shù)字實驗室為中心的各種實驗室，大大提高了學校的教學效率。而且隨著數(shù)字化實驗室的產(chǎn)生，對實驗室提高工作效率、降低運行成本起到很大的作用，這也正好符合目前國內(nèi)絕大多數(shù)實驗室的要求。很多工廠、企業(yè)都在逐漸建立以自動化的生產(chǎn)、管理和控制等為一體的現(xiàn)代化數(shù)字系統(tǒng)，達到自動化運行、信息化管理和無紙化辦公的目的。數(shù)字實驗對具有發(fā)展?jié)摿Φ腖IMS（實驗室信息管理系統(tǒng)）產(chǎn)品就顯得尤為重要。 |
