本文提出了用电子计算机及其辅助设备为二次仪表来采样、转换、处理,存贮及打印记录的方法,从而达到无时差、密集采样,并输出温度、温差、冷却速度的目的。为了克服在快速测温时热电偶响应时间长的缺点,提出了光电—光纤测温器作为一次仪表,为精确测定迅速变化的热场提供了可能。 In this paper, a method of sampling, converting, processing, storing and printing records by using a secondary computer with an electronic computer and its auxiliary equipment is proposed to achieve the purpose of no time difference, intensive sampling and output of temperature, temperature difference and cooling speed. In order to overcome the shortcomings of long thermocouple response time during rapid temperature measurement, a photoelectric-fiber thermometer is proposed as a primary instrument, which provides the possibility of accurately measuring the rapidly changing thermal field.
