On the basis of analyzing the output signal of a two wavelength beat - wave absolute distance interferometer, this paper proceeds from the realities of the aiming method of the beat - wave interferometer, conducts an analytical investigations on the dependence of the aiming accuracy of the beat - wave interferometer on laser dual - line output power equilibrium, propose two new concepts - a basic aim blind area and a blind area expansion, and establishes an analytical expression between the blind area expansion and the relative power difference of laser dual lines
本文從拍波干涉儀對準方法的實際出發，在分析雙譜線拍波干涉儀輸出信號的基礎上，研究了雙譜線功率不一致與拍波干涉儀對準精度的關系，提出了基本對準盲區和盲區擴大量的新概念，建立了描述盲區擴大量與雙譜線相對功率差之間關系的解析表達式。 -
In measuring distance, two common methods : pulse - counting and phase - shifting are compared and analyzed. we analyze and compare analog intervene method and time delay method according to their measuring precision and the measuring blind area to improve the measuring precision
對脈沖計數法中的兩種提高測量精度的插入法:模擬插入法和延遲線插入法的精度和測量盲區兩個方面作了分析和比較。 -
And now that s done, said the blind man ; and at the words he suddenly left hold of me, and, with incredible accuracy and nimbleness, skipped out of the parlour and into the road, where, as i still stood motionless, i could hear his stick go tap - tap - tapping into the distance
「現在，完事了。 」瞎子說，說完他就突然放開我，以令人難以置信的精確和敏捷竄出了客廳，到了路上。我獃獃地站在那裡，能聽得到他的棍子篤篤地探路的聲音，那聲音越來越遠了。
