Kev ntsuas qhov tseeb yog kev ua haujlwm ntawm kev tau txais cov ntaub ntawv muaj tseeb uas ze ze rau qhov tseeb tus nqi los ntawm kev tswj kev ntsuas qhov yuam kev nyob rau hauv ib qho me me uas siv cov cuab yeej technology siab heev.
1. Nqaim-sens Precision Measurement (Geometric Quantity Measurement)
Qhov no feem ntau tsom rau qhov kev txiav txim siab ntawm cov geometric tsis xws li qhov ntev, lub kaum ntse ntse, thiab cov duab, feem ntau pom nyob rau hauv cov khoom ntawm precision mechanical qhov chaw. Piv txwv li, hauv kev tsim cov tshuab chip lithography, qhov kev ua yuam kev loj ntawm cov khoom tseem ceeb yuav tsum tau mus txog qib nanometer, yuav tsum tau sub-micron qib ntsuas thiab ntsuas ntsuas siv siab - cov khoom siv precision xws li laser interferometers.
2. Broad -Sense Precision Measurement (Multidimensional Physical Quantity Measurement)
Qhov no txuas mus rau qhov ntsuas ntawm lub cev muaj nuj nqis xws li qhov kub thiab txias, cov khoom siv hluav taws xob, thiab cov yam ntxwv ntawm cov kua dej, txhawb siab -kev tsim khoom kawg thiab txiav- kev tshawb fawb ntug. Satellite cwj pwm tswj systems yuav tsum tau ib txhij saib xyuas ntawm ntau yam tsis, xws li gyroscope angular tshaj tawm kev ntsuas (qhov tseeb mus txog 0.001℃/ h) thiab onboard moos zaus stability nrhiav tau (yuam kev tsawg dua 1 × 10⁻¹³).
3. Cov ntsiab lus tseem ceeb ntawm kev siv
• Ntsuas Ib puag ncig Tswjhwm: Lub tshuab nqus tsev tsis tu ncua- qhov ntsuas kub yuav tsum tau siv rau kev ntsuas qhov ntsuas qhov ntsuas qhov xav tau txhawm rau txhawm rau txhawm rau ntsuas qhov kub thiab txias mus rau hauv 0.01℃.
• Ntsuas Ntsuas Qhov Ntsuas: Cov khoom siv atomic moos siv sijhawm tuaj yeem ua tiav qhov yuam kev tsis pub dhau 1 thib ob dhau kaum lab xyoo.
• Yuam Kev Tshem Tawm Tshuab: Sib koom tes ntsuas tshuab siv ntau-kev sojntsuam them nyiaj algorithms los txo cov kev ua yuam kev kom qis dua 0.5 micrometers.
