【摘要】 高精度测量温升是热量计智能化的主要问题。本文叙述了石英晶体用于测温的优点,对国产5MC测温晶体与国外测温晶体进行了对比实验与分析,给出了可供实用的石英晶体测温和单片机控制的恒温式热量计的硬件框图与软件流程。更多还原

【Abstract】 The main point in the microcomputer based carolimeter is thehigh accuracy measurement for the temperature rise. A series of advantagesfor the measuring with a quartz crystal is described in this paper. The com-parison between quarts in HP-2804A and that made in our country is giventogether with the results of the experiments.更多还原
