乙炔敏感元件的研制

DEVELOPMENT OF C2H2 GASSENSOR

以ＳｎＯ２为基质材料，掺杂微量的Ｐｄ，Ａｕ等元素制成了对乙炔敏感的气体传感器，研究了器件的灵敏度、响应、恢复特性、长期稳定性等敏感特性。结果表明该传感器具有一定的实用价值．

With the SnO2 as based materials,a kind Of C2H2 gas sensor is fabricated by dopingwith trace Pd,Au elements.Its sensitive properties such as sensitivity,response andrestorating properties,longterm stability and so on are studied.The results haveshowed that the sensor has practical prospect.
