Qhov tseem ceeb ntawm qhov kev kwv yees stereographic hauv crystallography muab los ntawm qhov tseeb tias cov ntsiab lus ntawm qhov chaw ntawm tus kheej muab qhov sawv cev ua tiav ntawm cov lus qhia hauv peb qhov chaw, cov lus qhia yog cov kab ntawm qhov nruab nrab ntawm tus kheej mus rau cov ntsiab lus.
Lub hom phiaj ntawm kev ua yeeb yam stereographic yog dab tsi?
Stereographic projection is a technique for displaying the angular properties of a aircraft faced object on ib daim duab lossis daim duab. Kev taw qhia nrog rau cov dav hlau tuaj yeem pom thiab txhua lub kaum sab xis uas xav tau tuaj yeem ntsuas ncaj qha los ntawm qhov projection siv cov txheej txheem graphical.
Dab tsi yog qhov kev ua yeeb yam stereographic khaws cia?
Stereographic projection preserves circles and angles. Ntawd yog, cov duab ntawm lub voj voog ntawm tus kheej yog ib lub voj voog hauv lub dav hlau thiab lub kaum sab xis ntawm ob kab ntawm tus kheej yog tib yam li lub kaum sab xis ntawm lawv cov duab hauv lub dav hlau. Qhov projection uas khaws cov kaum sab xis yog hu ua qhov kev pom zoo.
Lub ntsiab lus ntawm kev ua yeeb yam stereographic yog dab tsi?
: a daim duab qhia kev ntawm ib hemisphere qhia lub ntiaj teb kab ntawm latitude thiab longitude projected mus rau ib tug tangent dav hlau los ntawm radials los ntawm ib tug taw tes rau saum npoo ntawm lub kheej kheej opposite rau lubtaw tes ntawm tangency.
kev kwv yees kwv yees piav qhia nrog kev pab ntawm daim duab yog dab tsi?
Ib lub voj voog ncig qhia qhov twg kab lossis dav hlau uascuam tshuam qhov saum npoo ntawm ib qho (hemi) kheej kheej, muab cov kab / dav hlau kuj dhau los ntawm qhov chaw ntawm(hemi)sphere. B Lub voj voog loj: kev sib tshuam ntawm qhov chaw ntawm tus kheej nrog lub dav hlau. uas hla qhov nruab nrab ntawm tus kheej (piv txwv li, kab ntawm longitude)
