摘要
文申确定了能够在人体体温测量范围内变色的胆甾液晶混合物及其组成。通过改变混合体系申惰性添加剂的含量，获得在25℃-55℃范围内，变色温度精度为±（0．1-0．2）℃的一系列混合液晶组成。研究发现，混合液晶体系变色清亮点温度与添加剂加入量成良好的线性关系，线性相关系数最高可达到0．9991。
The cholesteric liquid crystal system have been studied in order to develop liquid crystal clinical thermometers instead of traditional mercurial thermometers. A number of cholesteric liquid crystal mixture, of which the thermoehromatic temperature degree of accuracy is ± （0.1-0, 2） ℃ in the range of 25 ℃ to 55 ℃, has been obtained by changing the content of the inert additive in the cholesteric liquid crystal system, The result shows that a plot of clearing point of temperature vs. the proportioning by weight of the additive in the liquid crystal mixture is a straight line over a wide range of temperatures and the linearly dependent coefficient is up to 0.9991.
