摘要
介绍利用电阻加热丝和印制基板材料设计制作的加热板作加热装置,用泡沫塑料作绝热材料,用晶体管数字温度计测量温度,并用直线拟合法测量液体比热容的方法.实验证明,用这种方法测量液体比热容,比传统方法更简便,测量误差更小.
This paper introduces the following four aspects:using heating board made of resistance heating silk and printed board as a heating instrument; using foam plastics as insulation materials; using a numerical transistor thermometer to measure temperature; using quasilinear method to measure liquid specific heat volume.
