長度計量器具使用中的溫度控制問題研究

【摘要】在長度測量過程中，待測物品會受到溫度的影響呈現(xiàn)出熱脹冷縮的現(xiàn)象，這不僅會導(dǎo)致測量失準，還會影響測量對象的形狀?；诖?，本文分析溫度與長度計量器具之間的關(guān)系與影響，并且在此基礎(chǔ)上制定溫度控制策略，保證長度測量的精準度。

【關(guān)鍵詞】長度計量器具；溫度變化；熱脹冷縮；控制技術(shù)

Abstract：During the length measurement process， the item to be measured will be affected by temperature and exhibit thermal expansion and contraction. This not only leads to measurement inaccuracy， but also affects the shape of the measurement object. Based on this， this article analyzes the relationship and impact between temperature and length measuring instruments， and develops temperature control strategies based on this to ensure the accuracy of length measurement.

Keywords：length measuring instruments； temperature changes； heat expansion and cold contraction； control technology
