以往,缺乏先进的测试手段,是高性能气敏材料和元件研制过程中的瓶颈之一,半导体气敏元件测试中的“反常现象”(用不同仪表测试同一元件,其参数差别有时会很大)是研制和测试中的一个理论障碍。我校电路 CAD 所承担的“微机在气敏材料研制及测试中的应用”课题最近通过鉴定,专家们听取了课题组在气敏材料测试机理和研制工作中的成就,现场测试验证了“闪电势”
In the past, the lack of advanced testing methods was one of the bottlenecks in the development of high-performance gas-sensing materials and components. The “anomaly” in the testing of semiconductor gas sensors (using the same components with different gauges, the difference in parameters can sometimes be large ) Is a theoretical obstacle in the development and testing. Recently, the project “Application of Microcomputer in Development and Testing of Gas-Sensitive Materials” undertaken by CAD of our school has passed the appraisal. The experts listened to the achievements made by the research group in the testing mechanism and research work of gas-sensitive materials. The field tests verified that “Lightning Potential ”
