No ke aha e koho ai i ka granite ma kahi o ka metala no ke kumu Granite no nā huahana tomography computed ʻoihana

I nā makahiki i hala iho nei, ua hoʻohana ʻia ka ʻenehana tomography computed i nā ʻoihana like ʻole no ka hoʻāʻo ʻana a me ka nānā ʻana ʻaʻole luku. He mea pono nā huahana tomography computed ʻoihana no ka kaohi maikaʻi a me ka hōʻoia palekana. He mea koʻikoʻi nā kumu o kēia mau huahana no ka hōʻoia ʻana i ko lākou kūpaʻa a me ka pololei. I ke koho ʻana i ka mea no ke kumu, ʻo ka granite ka mea makemake pinepine ʻia ma mua o ka metala no nā kumu like ʻole.

ʻO ka mea mua, he pōhaku kūlohelohe ka granite i hōʻailona ʻia e kona nui, paʻakikī, a me ke kūpaʻa. He haʻahaʻa kona coefficient o ka hoʻonui ʻana o ka thermal, ʻo ia hoʻi, ʻaʻole ia e hoʻonui a ʻaelike nui me nā loli o ka mahana. ʻO ka hopena, he kūpaʻa maikaʻi loa kona a me ke kiʻekiʻe o ke kū'ē ʻana i ka deformation a me ka haʻalulu. ʻO kēia ka mea kūpono no nā huahana tomography computed ʻoihana, e koi ana i nā pae kiʻekiʻe o ke kūpaʻa a me ka pololei.

I ka hoʻohālikelike ʻana, ua maʻalahi nā metala i ka hoʻonui ʻia a me ka ʻūlū ʻana ma muli o nā loli wela, kahi e kūpono ʻole ai lākou no nā huahana tomography computed ʻoihana. Hiki ke hoʻopilikia ʻia nā kumu metala e nā mea o waho e like me ke komo ʻana o ka electromagnetic, hiki ke hana i nā distortions a me nā hewa i nā heluhelu lako. Ma kēia ʻano, ʻoi aku ka hilinaʻi o ka granite no ka hōʻoia ʻana i ka pololei a me ka pololei o nā huahana tomography computed ʻoihana.

Eia kekahi, kūpaʻa ka granite i ka ʻaʻahu a me ka pala, ʻo ia hoʻi ka mea i ʻoi aku ka paʻa ma mua o nā metala he nui. ʻAʻole hoʻi he magnetic, ʻo ia hoʻi ka mea kūpono no nā noi kahi e hiki ai ke pilikia ka hoʻopilikia magnetic. Eia kekahi, he kiʻekiʻe ke kūpaʻa kemika o ka granite, ʻo ia hoʻi, ʻaʻole ia e pane me ka hapa nui o nā mea, e kūpono ai no nā noi e pono ai ka pololei a me ka palekana.

Ma ke ʻano o ke kumukūʻai, hiki ke ʻoi aku ke kumukūʻai o ka granite ma mua o kekahi mau metala, akā hāʻawi ia i kahi pae kiʻekiʻe o ke kumukūʻai no ke kālā i ka wā lōʻihi. ʻO kona kūpaʻa, kūpaʻa, a me ka pololei ʻana, ʻo ia hoʻi ka liʻiliʻi o ka mālama ʻana a me ka hoʻololi ʻana i ka hala ʻana o ka manawa, hiki ke hopena i nā mālama kālā nui no nā mea hana huahana computed tomography ʻoihana.

I ka hopena, ʻoiai he mea pono ka metala no nā noi ʻoihana he nui, ʻo ka granite ke koho makemake ʻia no nā kumu o nā huahana tomography computed ʻoihana. ʻO kona mānoanoa, paʻakikī, kūpaʻa, a me ke kūʻē ʻana i ka ʻaʻahu, ka pala, a me nā hopena kemika e lilo ia i mea kūpono no ka hōʻoia ʻana i ka pololei, ka pololei, a me ke kūpaʻa o kēia mau huahana. Eia kekahi, hāʻawi ka granite i ka waiwai no ke kālā i ka wā lōʻihi, e lilo ia i mea hoʻopukapuka akamai no nā mea hana o nā huahana tomography computed ʻoihana.
