水對科學家而言有無限的魅力，尤其在低溫時其許多奇特的現象。例如在低溫時水會結晶，但是水也可在低於凝結點時以液態的形式存在。許多人研究低溫下水的有趣現象，甚至也已經研究出同一種水可以存在兩個相變點[1]。先前已經有人做過有關在低溫時被侷限在奈米孔洞內水的熔點、黏滯係數、壓縮係數、擴散係數[2-4]等等研究，這回我們想利用實驗室擁有的設備來研究在不同奈米尺度下水的比熱與溫度的相依性，這也是研究奈米尺寸下水的熱力學性質的開端 。
此外，過程中學習到很多東西，包括了解LabView圖控式程式語言、測量AC比熱、DSC比熱、架設TGA熱重分析儀等技術，相信對於未來會有很大幫助。

Water is a continuous source of fascination to scientist because of its many counterintuitive low-temperature properties. Although the stable from of water at low temperature is crystalline, liquid water can also exist below the melting point. Many people study the interesting phenomenon of water at low temperature and it is found that two critical points may even coexist in a single component liquid [1]. The other properties of water, like melting point, viscosity, compressibility, self-diffusion constant have also been studied below low temperature [2-4]. Now, we want to take the advantage of the equipment we have in our laboratory to measure the temperature dependence of Cp of water confined in different scale of nano-pores. This is also the beginning for people to study the thermodynamic properties of water confined in nano-pores.
In addition, I have learned a lot, such as to understand LabView graphical programming language, the skill to measure AC specific heat, DSC specific heat, and to set up TGA. It will be helpful for me in the future, I think.
