本文对普通光学显微镜难以区分和鉴别的白蚊伊蚊和埃及伊蚊卵，以扫描电子显微镜进行了形态观察。
The scanning electron microscope had been used for surface observation of the eggs from Aedes albopictus and Aedes aegypti which are difficultly distinguished from each other by optical microscope.
它具有优良的光学性质和颜料性能，纯度高，白度，色彩还原能力和分散性。
It has excellent optical character and pigment performance, high purity, whiteness, tint reducing power and dispersibility.
由此可见，白度是指肉眼直接观察的对比结果，而亮度则是指光学反射的对比结果。
It can be seen, then, that whiteness is directly determined through comparative ocular eye, whereas brightness refers to comparative optical reflectance.
