摘　　要：改进电热法测量比热容方法中使用的物理公式,使实验电路更为精简。在以往比热容测定仪器的基础上进行改良,制作出新的比热容测定装置,并通过实验验证该装置测定物质比热容所能达到的精确度。对实验的数据处理方法进行改进,并验证其精度。Improving physics formulas electric heat capacity measurement method is used to make the experi-ment more streamlined circuit. Be based on the specific heat capacity of a conventional measuring instrument on the improvement of the production of a new heat capacity measuring apparatus,the apparatus and experi-ments measuring the specific heat capacity of the material can be achieved by precision. Improved the process-ing methods of the experimental data and verify its accuracy.
