One of these parameters is ground whiteness which is obtained by first bleaching and another is optical whiteness process by optical brightening agent application.
其中一个参数是通过第一次漂白获得的地色白度，另一个参数是通过应用荧光增白剂获得的荧光白度工艺。
It has excellent optical character and pigment performance, high purity, whiteness, tint reducing power and dispersibility.
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 can be seen, then, that whiteness is directly determined through comparative ocular eye, whereas brightness refers to comparative optical reflectance.
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。
