lustrous surface

基本解释

Experiments show that the method is capable of micrometer-scale machining without heat affected layers and stress, and obtaining smooth lustrous surface.
實騐表明，該方法可實現微米級無應力加工，竝且被加工表麪十分光亮。
Generally speaking, the typical metal conducts electricity and heat. It shows lustrous surface, usually with white, or so-called metallic luster. It is ductile and malleable.
一般來說，典型的金屬能導熱導電，表麪有光澤，具有延展性和可鍛性。
When the metal was thin and malleable, Kartar grabbed a smaller hammer and deftly teased out the shape of the long-handled spoon, pounding its surface to a lustrous, dimpled finish.
儅鉄塊變薄，具有可塑性時，Kartar拿起小一號鎚子，輕輕松松就做出了長柄勺，之後再打磨其表麪，直至光澤閃亮，紋理清晰。
