Pehea e helu ai i ka nui o kahi papa alakaʻi alakaʻi cylindrical?

1. E hoʻoholo i keʻano o ka cylinder: e ana i ka diameter o ka cylinder,ʻo ia ka mamao ma keʻano o ka cylinder.

2. E hoʻoholo i ke kiʻekiʻe o ka cylinder: e ana i ke kiʻekiʻe o ka cylinder,ʻo ia ka mamao mai ka lalo a i lalo o ka cylinder.

Palapalaʻokoʻa = π X CRINT DIAMETER X Screen kiʻekiʻe. I waena o lākou, π kaʻikeʻo Pi, kahi e like me 3.14159.

No ka laʻana, ināʻo keʻano o ka cylinder he 2 mau mika aʻo ka kiʻekiʻe he 4 mau mika o ka pā.

E hoʻomaopopo e pili ana i kēiaʻano helu helu e pili ana i ke kiʻiʻana i nā screens i alakaʻiʻia me nāʻano cylindrical cylindrical. Ināʻaʻole he cylinder mau ka pākeke i ka cylinder maʻamau, pono e heluʻia ka heluʻana i ke kūlana maoli.

ʻO kaʻike liʻiliʻi loa o ka lōʻihi o ke ala cylindrical i alakaʻi = pixel spacing (mm) x 1000/1000

ʻO kaʻike kūpono loa no ka lōʻihi o nā kiʻi cylindrical i alakaʻiʻia = Pixel space (mm) x 3000/1000

ʻO ka lōʻihi o ka nānāʻana i ka lōʻihi o ke ala cylindrical i alakaʻiʻia = screen kiʻekiʻe (mika) x 30 (mau manawa)

No ka laʻana,ʻo kaP3 kumu hoʻohālikeʻO ka hōʻike hōʻike hōʻike Cylindrical i kahi pikika pixel i ka 3mm, no laila ke nānā aku nei kaʻike maikaʻi loa 3 x 3000/1000 = 9 mau mika. ʻO kaʻoiaʻiʻo,ʻo ka lōʻihiʻikeʻikeʻia he mamaoʻikeʻia no kaʻike kiko'ī.

ʻO ka mālamalama e pono ai e noʻonoʻo a hoʻoponoponoʻia e like me nā kūlana ma nā pūnaewele ma nā papahana maoli.
