本文以ＳｎＯ_２为基体材料，通过几种稀土元素的掺杂，研制了乙炔气敏元件，大量的实验表明，掺入稀土元素钐对于Ｃ_２Ｈ_２的选择性和灵敏度有明显的提高．
In this paper, the acetylene gas sensor has been developed by doping SnO_2 with several kinds of rare earth elements. A large number of experiments show that the selectivity and sensitivity of rare earth element samarium to C_2H_2 are obviously improved.
