金属镜 meaning in Chinese

metal mirror
specula
speculum

Then some cavity quantum electro - dynamic ( cqed ) effects are studied by experiment . the photoluminescence ( pl ) intensity enhancement at resonance wavelength and suppression at off - resonance wavelength , emission spectrum narrowing as well as emission intensity redistribution in space are observed in the microcavity device fabricated with distributed bragg reflector ( dbr ) and silver mirror as well as that done with two silver mirrors
分别在带有dbr结构的平面微腔及全金属镜构成的平面微腔中观察到了谐振模式处的辐射增强及非谐振模式处的辐射抑制，发射谱线窄化以及辐射强度空间分布重组等腔量子电动力学现象。
