同轴表面波激励器和微波等离子体炬是两种获得微波等离子体（ＭＷＰ）的装置，本文比较了用这两种装置获得的ＭＷＰ作原子发射光谱法光源时的分析性能，结果表明这两种装置各有优点，但微波等离子体炬效果更好。
Coaxial surface wave exciters and microwave plasma torches are two devices for obtaining microwave plasma (MWP). In this paper, we compare the analytical performance of MWP obtained by these two devices as the source of atomic emission spectrometry. The results show that these two The devices have their own advantages, but the microwave plasma torch better.
