“monochromatic light source”的概念、定义、翻译、参考文献-科学参考

单词	monochromatic light source
释义	monochromatic light source Encyclopedia 理学〔一般光源〕释 monochromatic light source单色光源产生单一频率光的光源。自然界中不存在严格意义上的理想单色光，因为它要求是一个无限长时间的等幅正弦（或余弦）振荡的电磁波。因此，通常说的单色光源实际发出的都只是准单色光，即光谱线型半高宽与中心波长的比值很小，它很接近单色，习惯上就把这类光源称为单色光源。 Physics 光学、声学光学 monochromatic [light] source单色光源
