摘　　要：针对桥丝式电雷管电热响应无损检测的通用测试系统,提出了系统的电热转换灵敏度的概念并推出其一般表达式。利用测试系统的这个特性参数,能方便地将输出端的电压数字量换算成被测对象的温升,大大地简化计算,可以作为研究电热响应无损检测方法的一个重要手段。A concept of electro-thermal sensitivity is presented and the formula for the general nondestructive test system of bridgewire-electroexplosive device is derived. The electro-thermal sensitivity of the test system can be used to simplify the calculation in converting the digital value of voltage in output point to the temperature of the object tested, and it can serve as a measure in the study of electro-thermal nondestructive test.
