Cov radius ntawm curvature ntawm a nkhaus ntawm apoint M(x, y) hu ua inverse of the curvature K ntawm nkhaus ntawm no: R = 1K. Li no rau dav hlau curves muab los ntawm qhov tseeb kev sib npaug y = f(x), cov radius ntawm curvature ntawm qhov taw tes M(x, y) yog muab los ntawm cov lus hauv qab no: R = [1+(y'(x))2]32|y''(x)|.

Ib yam li ntawd, nws yog nug, lub vojvoog ntawm curvature ntawm parabola yog dab tsi?

Daim ntawv thov ntawm Radius ntawm Curvature Peb hais qhov nkhaus thiab lub voj voog osculate (uas txhais tau hais tias "mus hnia"), txij li 2 nkhaus muaj tib qhov sib npaug thiab curvature ntawm qhov chaw uas lawv ntsib. Cov radius ntawm curvature ntawm qhov nkhaus ntawm ib qho chaw tshwj xeeb yog txhais raws li qhov lub vojvoog ntawm lub voj voog kwv yees.

Ib yam li ntawd, lub vojvoog ntawm curvature ntawm lub dav hlau nto yog dab tsi? Piav koj cov lus teb. O Cov radius ntawm curvature ntawm aplane iav yog sib npaug rau xoom. Nyob rau hauv cov nqe lus ntawm daim iav sib npaug, yog di -do, ces yuav tsum mus rau infinity, uas txhais tau tias r 2f O The radius ntawm curvature ntawm ib lub dav hlau iav yog sib npaug rau infinity.

Kuj kom paub, lub vojvoog ntawm curvature yooj yim txhais yog dab tsi?

Radius ntawm curvature (ROC) muaj lub ntsiab lus tshwj xeeb thiab kos npe rau hauv kev tsim kho qhov muag. Lub lens spherical los yog mirrorsurface muaj qhov nruab nrab ntawm curvature nyob ib sab ntawm ordecentered los ntawm qhov system hauv zos optical axis. Qhov kev ncua deb ntawm lub vertex mus rau qhov chaw ntawm curvature yog cov radius ntawm curvature ntawm qhov chaw.

Yuav ua li cas koj xam lub vojvoog?

Cia li nco ntsoov faib txoj kab uas hla los ntawm ob mus rau lub lub vojvoog . Yog tias koj nug nrhiav tus lub vojvoog es tsis txhob ntawm txoj kab uas hla, koj yuav yooj yim faib 7 ko taw los ntawm 2 vim lub lub vojvoog yog ib nrab ntsuas ntawm txoj kab uas hla. The lub vojvoog ntawm lub voj voog yog 3.5 feet. Koj tuaj yeem siv lub voj voog thiab lub vojvoog kev sib npaug.
