ʻO ka ʻokoʻa ma waena o ke kaulahao 12B a me ke kaulahao 12A

1. Nā ʻano like ʻole

ʻO ka ʻokoʻa ma waena o ke kaulahao 12B a me ke kaulahao 12A ʻo ia ka moʻo B he imperial a hoʻokō i nā kikoʻī ʻEulopa (ka mea nui Pelekane) a hoʻohana mau ʻia i nā ʻāina ʻEulopa;ʻO ka moʻo A ʻo ia hoʻi ka metric a hoʻokō i nā kikoʻī nui o nā kūlana kaulahao ʻAmelika a hoʻohana mau ʻia ma ʻAmelika Hui Pū ʻIa a me Iapana.a me nā ʻāina ʻē aʻe.

2. Nā nui likeʻole

ʻO ka pitch o nā kaulahao ʻelua he 19.05MM, a ʻokoʻa nā nui ʻē aʻe.Ka wae o ka waiwai (MM):

Nā palena kaulahao 12B: ʻo 12.07MM ke anawaena o ka huila, ʻo ka laulā o loko o ka ʻāpana i loko he 11.68MM, ʻo ke anawaena o ka pine pine he 5.72MM, a ʻo ka mānoanoa o ka pā kaulahao he 1.88MM;
12A mau kaulahao: 11.91MM ke anawaena o ka wili, 12.57MM ka laula o loko o ka pauku, 5.94MM ke anawaena o ka pine pine, a he 2.04MM ka mānoanoa o ka pae kaula.

3. Nā koi kikoʻī like ʻole

Loaʻa i nā kaulahao o ka pūʻulu A i nā wili a me nā pine, ua like ka mānoanoa o ka pā kaulahao i loko a me ka pā kaulahao waho, a loaʻa ka hopena ikaika like o ka ikaika static ma o nā hoʻololi like ʻole.Eia nō naʻe, ʻaʻohe ʻike maopopo ma waena o ka nui nui a me ka pitch o nā ʻāpana B series.Ma waho aʻe o ka 12B kikoʻī i haʻahaʻa ma mua o ka moʻo A, ʻo nā kikoʻī ʻē aʻe o ka moʻo B e like me nā huahana A series.
