Pehea e ʻike ai i ka maikaʻi o nā paipu kila ʻole?
1. Hiki i nā paipu kila hoʻopunipuni a haʻahaʻa ke pelu.
ʻO ka hoʻopili ʻana he ʻano creases i hana ʻia ma ka ʻili o nā paipu kila, e holo pinepine ana ma ka ʻaoʻao longitudinal o ka huahana holoʻokoʻa.ʻO ke kumu o ka hoʻopili ʻana ma muli o ka ʻimi ʻana i ka hana kiʻekiʻe e nā mea hana hoʻopunipuni a haʻahaʻa, e hopena i ka hoʻohaʻahaʻa nui ʻana a me ka hanauna o nā pepeiao.Hana ʻia ka pelu ʻana i ka wā o ka ʻōwili ʻana aʻe, a e pohā ka hua i pelu ʻia ma hope o ke kulou ʻana, e hopena i ka emi nui o ka ikaika o ke kila.
2. ʻO ke ʻano o nā paipu kila hoʻopunipuni a haʻahaʻa e hōʻike pinepine ana i ka lua.
ʻO ka pitted surface kahi hemahema i hoʻokumu ʻia e ka ʻaʻahu nui a me ka haehae ʻana i ke aʻe o ka ʻōwili, ka hopena i ka ʻole like ʻole o ka ʻili kila.Ma muli o ka ʻimi ʻana i ka loaʻa kālā e nā mea hana paipu kila hoʻopunipuni a haʻahaʻa hoʻi, aia nā hihia ma mua o ka maʻamau.
3. ʻO ka ʻili o nā paipu kila hoʻopunipuni a haʻahaʻa loa i ka scabbing.
ʻElua kumu: (1) ʻAʻole kūlike nā mea o nā paipu kila hoʻopunipuni a he nui nā mea haumia.(2) Mea hoʻopunipuni a haʻahaʻa
