The size of the arrows indicates the relative speed of plate motion.(箭頭的大小代表了相應的板塊移動速度。)

Keyboard code location relative speed equivalence is a basic data for optimizing Chinese-character keyboard entry and can be used to compare various Chinese-character entry methods scientifically.(鍵位相關速度當量表是優化漢字鍵盤輸入健位設計的人機工程基礎據，也為自動測定漢字鍵盤輸入方法速度素質提供了科學依據。)

Even someone who knows nothing about StarCraft can be brought up to relative speed within the duration of a quick 3-4 minute explanation.(即便是一個對星際一無所知的人，通過3-4分鐘的解說和觀看也能對星際達到相當程度的了解。)

To reiterate a very important point, three positions for a new FMO are necessary for the Minor Planet Center (MPC) to determine if a FMO's earth relative speed is accelerating or decelerating.(反復強調一點：三個位置對于新的FMO發現是必需的。只有必須有三個點，國際小行星中心(MPC)才可以確定它對于地球是加速運動還是減速。)

Electromagnetic Log is a relatively Log, and for single Log, the only measurement of the vertical ship relative speed of water, range, not conducive to the manipulation of large ships.(電磁計程儀是一種相對計程儀，且為單軸計程儀，只能測量船舶相對水的縱向航速、航程，不利于大型船舶的操縱。)

But the satellites will arrive with less relative speed than spacecraft making the trip in three days, which means less fuel will be needed to brake and drop into lunar orbit.(但是相比太空飛船，衛星著陸時需要相對小的速度，這將需要三天的時間，意味著消耗更少的燃料進入繞月軌道。)

The relative speed between driving wheel and pin rail varies with sinusoidal function. 2 When the torque of driving wheel is unchanged, the traction force varies with the...(當驅動輪轉矩不變時，牽引力隨嚙合點的變化而呈周期性變化。每個輪齒受到的銷軌反力是脈動的，脈動幅值較大。)

Our special speedometer shows that the relative speed between the two trains is 20 MPH.(我們特制的測速儀表現這兩列火車的相對速率是每小時20英里。)

If your answer is yes, then you are wrong again. All we can be certain of is that the relative speed between the two trains changed.(如果你回答說是的，那么你就又錯了。我們所能夠完全肯定的一點只是這兩列火車之間的相對速度變了。)

The relative speed between the trains remains the same, 10 mph; and the end result will be the same.(假如兩列火車之間的相對速率依然溝通，都是每小時10英里，那么最終的功效也會是溝通的。)
