玻璃温度计是一种得到普遍应用的温度测量仪表。本文在建立了玻璃温度计数学模型的基础上,从稳态响应和瞬态响应两个方面分析了它的动态特性,对它用于动态温度测量时会产生的误差及其减小的途径进行了讨论。
Glass thermometer is a commonly used temperature measuring instruments. Based on the establishment of mathematical model of glass thermometer, this paper analyzes its dynamic characteristics from two aspects of steady state response and transient response. The error and the way of decrease when it is used in dynamic temperature measurement discuss.
