Lub cev grey txhais tau
Yog hais tias monochromatic nqus ntawm ib yam khoom yog ywj siab ntawm qhov ntev ntawm lub zog ci ntsa iab ua tiav rau lub nruas, uas yog, = α = tas mus li, nws hu ua lub cev grey.
Kev ntsuas hluav taws xob ntawm ib yam khoom yog tas mus li, thiab qhov piv ntawm hluav taws xob siv ntawm txhua lub suab hluav taws xob ntawm txhua qhov hluav taws xob rau qhov ntsuas hluav taws xob rau qhov hluav taws xob sib xyaw ntawm cov nthwv hluav taws xob ntawm cov neeg sib txig sib nqus ntawm tib neeg lub cev ntawm qhov ntsuas kub yog tas mus li, tom qab ntawd cov kwv no hu ua qhov zoo tshaj plaws lub cev grey. , lossis tsuas lub cev Grey. Cov kev sib raug zoo ntawm qhov hluav taws xob tsis txaus thiab qhov ntev ntawm ib qho khoom nruab nrab ntawm qhov ntsuas kub tsis xwm yeem, yog li nws tsis yog grey. Tab sis rau lub hom phiaj ntawm yooj yim nyob rau hauv kev suav engineering, lawv txhua tus txawm grey lub cev kwv yees li.
