水立方薄膜（ETFE膜）导热系数的测定

摘要

University innovation experiment program is an important step to train student＇s ability of innovation in our higher education. It aims at training students＇ innovation and practical ability. This article studies on the program of the thermal conductivity of ETFE film we have used, and measures the thermal conductivity by the steady-state method. We find it is smaller than 0, 23W/m · ℃. So it can save the energy efficiently and serve as an ideal insulation material used in the architecture and other fields.%大学生创新实验项目是我国高等教育培养当代大学生创新能力的一项重要举措，它旨在培幂大学生的创新意识和动手能力。上海工程技术大学对申请到的大学生创新实验项目“水立方薄膜（ETFE膜）热传导特性的研究”做了深入探讨，利用稳态法测得了ETFE膜的导热系数，发现其值小于0．23W／m·℃，可以作为理想的绝热材料应用在建筑等领域，有效地节省电能，符合当前的绿色经弃的要求。
