On a submarine there was no more precise rangefinder . 在潛艇中,沒有比他們更精確的測距儀了。
As the range dropped to four thousand, the option to surface was dimming . 等到測距降到四千碼的時候,升上水面的機會就暗淡了。
Aerodist is a useful equipment for secondary breakdown, but not for primary control . 航空微波測距儀是測定二等補充網的有效儀器,但不能用于一等控制網測量。
It can be carried out with microwave equipment at a season when visibility may make anything else impossible . 在通視情況使得其它儀器都無法應用的季節內,可用微波測距儀測量。
The geodimeter measurements executed in april also disclosed very rapid and complicated horizontal crustal movements . 四月份進行的光電測距儀測量也揭示水平地殼運動是非常快而復雜的。
The original radar combined these two things, as its english name radar showed: radio detection and ranging . 最初的雷達正如它的英文名稱“雷達”(RADAR)所表示的那樣,包括兩個方面:無線電測物和測距。
