摘　　要：该文阐述了滴点测定仪温度测试系统的优化设计原理、方法及试验对比,研究证明:优化设计后的滴点测定仪温度测试系统用于替代玻璃温度计显示温度,其在玻璃液体温度计准确度的基础上,其分辨力和准确度有较大提高和改善,并实现了模拟显示到数字显示和记录的转变,便于计量确认,进一步提高了试验准确性和可靠性。Optimum design principle, method and test comparison of temperature test system for dropping-point tester are introduced in this article. The research proved that, the temperature test system of dropping-point tester can be used to replace glass thermometer to indicate temperature after optimum design, and its resolution and accuracy have been greatly improved comparing with those of glass thermometer. The transition from analogue indication to digital indication and record has also been realized. Thus, it can help to make measuring easy and to improve the accuracy and reliability of temperature measurement.
