「流行起於高分子,變化盡藏微宇宙」! 歡迎光臨「流變學好簡單 | The RheoMaster」部落格,成立於 2019/2/22,已於 2024 年初屆滿 5 年!旨在提供簡單的中文流變學知識,包括高分子流變學、輸送現象、高分子加工、流變量測等。您可至右方進行關鍵字搜尋,若有任何建議,請至文章留言或來信 yuhowen@gmail.com。 Welcome to "The RheoMaster" Blog. This website was established in Feb 2019, and has celebrated its 5th anniversary in eary 2024. In view of the lack of Chinese literature on rheology, here we offer basic knowledge relevant to polymer rheology, transport phenomena, polymer processing, rheometry, etc. If you have any suggestion, please leave a message on the post you are reading or email us at yuhowen@gmail.com.

如何自圖片取出數據值 (How to Extract Data from images)

如何將圖檔的數據值取出? 這裡介紹一個免費的線上軟體 "WebPlotDigitizer"。

👉 選取一張圖檔 (Load Image)

👉 於 X 軸點出 X1、X2,Y 軸點出 Y1、Y2,並鍵入座標值,勾選 Log Scale (Axes Calibration)


👉 點取想要數位化的數據點,例如圖中 120 度的實驗數據 (Add Point)

👉 檢視數據 (View Data)

👉 下載 .CSV (Download .CSV)

👉 清除數據 (Clear Data)

👉 重覆以上步驟,進行下一次的數據擷取 (Add Data)

👉 擷取三個溫度的數據如下
