Pehea e ʻike ai i ka paʻakikī o ka hana ʻana o ka flange kila kila

ʻO ka mea mua, ma mua o ke koho ʻana i ka drill bit, e nānā i nā pilikia o ka stainlesshili kilahana ʻana. E ʻike i ka paʻakikī hiki ke pololei loa, wikiwiki loa e ʻike i ka hoʻohana ʻana i ka drill. He aha nā pilikia i ka hana ʻana i ka flange kila? ʻO ka pahi paʻa: ʻo ka paʻakikī o ka ʻoki ʻoki ʻana i ka wela. Ke kahe ka puʻupuʻu ikaika ma ka ʻaoʻao ʻoki mua, e hoʻopili ʻia, fusion welding a me nā mea hoʻopili ʻē aʻe, e pili ana i ka ʻōlinolino o nā ʻāpana i hana ʻia; He paʻakikī ka hana.

I ka ai ana onā lehelehe nui, nui nā mea hana e pili ananā lehelehe nui. Eia mākou e kamaʻilio e pili ana i kekahi mau mea maʻamau. ʻO ka mea mua, ʻo ia ka mahana hoʻopulapula (ʻo ka mahana o ka annealing ka palena wela o ka primer a me ka template, inā ʻo 50% o ka primer a me ke kaʻina hoʻohui ʻia ka mahana o nā molekole DNA i kau ʻia.

He mea koʻikoʻi ia e pili ana i ka kikoʻī o PCR. I ka hihia o ka aspiration, he haʻahaʻa loa ka mahana annealing e hōʻoia i ka pale ʻana o ka primer me ke kaʻina pahuhopu, a lawa ka kiʻekiʻe e hōʻemi i nā kaʻawale nonspecific. ʻO nā mahana annealing kūpono mai 55 ℃ a 70 ℃. Hoʻonohonoho ʻia ka mahana annealing ma 5 ℃ haʻahaʻa ma mua o Tm o ka primer.
