拉伸試驗(yàn)處理數(shù)據(jù)

1、用origin9處理拉伸試驗(yàn)的數(shù)據(jù)，拉伸試驗(yàn)用了引伸計(jì)，求材料的屈服強(qiáng)度和抗拉強(qiáng)度。一、數(shù)據(jù)的導(dǎo)入和畫圖。1.將拉伸數(shù)據(jù)導(dǎo)入origin9中。點(diǎn)擊如圖所示的按鈕。然后在跳出來的ImportWizard-Source對話框里選擇拉伸試驗(yàn)的路徑的文件，AddFile并OK,再點(diǎn)擊ImportWizard-Source對話框中的Finish按鈕?；豋riginFto964-brt-D:OnginLabu5rfilesusersampleUNTITLED-/Faldsrl/-IBookiIFirfditVitvjPaiColumnWartahertAnnlysiiStatistic!TrnngfTco
