diameter ratio

基本解釋

The trim exponents vary with the fluid viscosity and impeller diameter ratio at same time.
切割指數(shù)同時(shí)隨著切割后的直徑比和液體粘度變化而變化。
This makes them incredibly strong and incredibly light, and they've already been manufactured in strands with a length-to-diameter ratio of 132 million to one.
這使得它們非常牢固但又令人難以置信的輕，并且它們已經(jīng)被用來生產(chǎn)出長度直徑比為1.32億的繩鏈。
That's pretty common: A single column of tennis balls would have a cylinder-to-sphere diameter ratio close to 1. (Chan's Christmas ornaments were just a touch over the 2.7013 limit.)
這非常普遍：一層網(wǎng)球的圓柱體與球體直徑比接近1（陳和奎的圣誕飾品剛過2.7013的上限)。
