Polishing 拋光

cucumber

Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values.

When an unpolished surface is magnified thousands of times, it usually looks like a succession of mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with a coarse grain size and gradually proceeds to the finer ones to efficiently flatten the surface imperfections and to obtain optimal results.

拋光
拋光是通過摩擦或應用化學處理來創建光滑和有光澤的表面的過程，留下具有顯著鏡面反射的清潔表面（根據菲涅爾方程仍然受材料折射率的限制）。 材料（如金屬、玻璃、黑色或透明的石頭），拋光也能夠將漫反射減少到最小值。

當一個未拋光的表面被放大數千倍時，它通常看起來就像一連串的山脈和山谷。通過反復磨損，這些“山脈”被磨損，直到它們變平或變成小“山丘”。 用磨料進行拋光的過程從粗粒度開始，逐漸進行到更細的粒度，以有效地平整表面缺陷並獲得最佳結果。
