通过对绢毛板甲藻（Plateumaris sericea）的结构观察和反射光的光谱分析，探讨了绢毛板甲藻金属色在同一种植物中广泛变化的物理机制。鞘翅表面由上表皮层和外表皮层组成，两者均具有高折射率层和低折射率层。只有上表皮具有可以理解的光学厚度，大约是光波长的四分之一。理论分析的结果与实测光谱反射进行了比较。
The physical mechanisms responsible for the wide variation of metallic color within a single species, Plateumaris sericea, were investigated by the structural observations and the spectral analysis of the reflected light. The surface of elytra consisted of epicuticle and exocuticle, both having high and low refractive index layers. Only the epicuticle had the understandable optical thicknesses of approximately one- quarter of the wavelength of the light. The results of theoretical analysis were compared with the measured spectral reflections.
