base line measurement

基本解释

A laser collimating system supplies a base line which is used for coaxiality measurement.
激光準直系統的研制是爲了提供大軸同軸度測量中需要的一條基準直線。
A high-precision base line indoor was build using double frequency laser interferometer as the measurement standards.
採用室內雙頻激光乾涉儀爲計量標準，建立了一條高精度室內基線。
The contrast analysis of measured results showed that the length of the image base line had no effect on the measurement of height difference under stereomodel.
測量結果的對比分析表明，象基線對立躰模型下的地形高差測量沒有影響，現用高差計算公式不能給出正確的結果。
