Nrhiav qhov ntim ntawm ib txheej spherical

Hauv qhov kev tshaj tawm no, peb yuav txiav txim siab cov qauv uas tuaj yeem siv los xam qhov ntim ntawm cov txheej txheem kheej kheej (slice ntawm lub pob), nrog rau cov piv txwv ntawm kev daws teeb meem los ua kom pom lawv cov kev siv tswv yim.

Kev txhais ntawm ib txheej spherical

Spherical txheej (los yog hlais pob) - qhov no yog qhov seem ntawm ob lub dav hlau sib luag sib tshuam. Daim duab hauv qab no yog xim daj.

• R yog lub vojvoog ntawm lub pob;
• r₁ yog lub vojvoog ntawm thawj txiav puag;
• r₂ yog lub vojvoog ntawm lub hauv paus txiav thib ob;
• h yog qhov siab ntawm cov txheej txheem kheej kheej; perpendicular los ntawm qhov chaw ntawm thawj lub hauv paus mus rau qhov chaw ntawm lub thib ob.

Formula los nrhiav qhov ntim ntawm ib txheej spherical

Yuav kom nrhiav tau lub ntim ntawm ib tug kheej kheej txheej (slice ntawm ib lub pob), koj yuav tsum paub nws qhov siab, raws li zoo raws li lub radii ntawm nws ob lub hauv paus.

Tib cov qauv tuaj yeem nthuav tawm hauv ib daim ntawv sib txawv me ntsis:

Sau ntawv:

• yog tsis yog lub hauv paus radii (r₁ и r₂) lawv diameters paub (d₁ и d₂), tom kawg yuav tsum muab faib los ntawm 2 kom tau txais lawv cov radii sib xws.
• tooj π feem ntau sib npaug mus txog 3,14.

Piv txwv ntawm qhov teeb meem

Nrhiav qhov ntim ntawm ib txheej spherical yog tias lub voj voog ntawm nws cov hauv paus yog 3,4 cm thiab 5,2 cm, thiab qhov siab yog 2 seej.

tshuaj

Txhua yam peb yuav tsum tau ua nyob rau hauv cov ntaub ntawv no yog los hloov qhov paub qhov tseem ceeb rau hauv ib qho ntawm cov qauv saum toj no (peb yuav xaiv qhov thib ob ua piv txwv):
