鑽石名詞術語 臨界角 ( Critical angle ) 法線和最大折射所產生的夾角,也是鑽石內部光線能夠逸出的最大角度,在臨界角內碰觸鑽石內部表面的光線,會以幾乎平行鑽石表面的方向逸出,鑽石的臨界角為24.5度。 刻小面 ( Brillianteering ) 定位及磨出星形刻面、腰上刻面及腰下刻面的步驟。 刻主面 ( Blocking ) 乃磨光...

The people to the diamond processing, have experienced road of the long fumble.Until in 1919, lived abroad US's Polish mathematician Tucker gas base, according to the diamond critical angle, designed according to the entire principle of reflection has 58 facet sign director circle diamonds to car...
MATT: There is a side window on the opposite end of there that you can open up and look through and there is an angle that you can see the Overcrow from that far window on that side, or the front door. Those are two viewpoints you have. ...
In addition, a vibration occurs in the system continuously as the CF occurring during machining depends on many factors such as distance between cutting edges, position angle, workpiece geometry, spindle deflection, depth of cut, chip width, feed rate, cutting speed and espe...
across all media. For a category of fiction predicated on imagining worlds stranger than and off at an angle to our own, it seems a rather glaring failing to exclude the minority aspects of human sexual identity from the vast majority of its stories. With a few notable, excellent exceptions...

One of the shortcomings of cavity-based OLED displays is their white angular dependence, which causes the display to shift color and brightness at different angles. On our Pixel 2 XL unit, the display lost little light when tilted at an angle,but experienced a severe case of angular color sh...
