Ke thermal conductivity o ke keleawe. A kupaianaha waiwai

ke kūlana o ke keleawe hiki ole ke overemphasized i loko o ka mōʻaukala o ke kanaka noho maikai ana. Ua ua me hoomaka ae la i kona mau kanaka e hoʻoikaika i metallurgy, au aʻo e hana i na mea paahana, Pottery, Jewelry, a me ke kala. A me nā mahalo i ka kūlana waiwai o keia metala, ua hoike mai ma ka oka a me nā waiwai. Kekahi mea palupalu, i kekahi mau nō, ke refractory, e heheʻe ko Hawaiʻi keiki. Ua he nui kona maikaʻi ano, a me kekahi o ia mea i ka thermal conductivity o ke keleawe.

Inā mākou e kamaʻilio e pili ana i keia ano, ia mea e pono ai ka mea ma ka pahu e möakäka hou. Kapaia thermal conductivity o ka waiwai, e hoolilo wela mai ka hahana loa hapa i ke anu. No laila, i ka thermal conductivity o ke keleawe melemele i kekahi o waena o ke hooheheeia i ka lani kiekie loa. Pehea la e hiki ai ke loiloi i keia waiwai me ka maikai paha, he ino paha?

Inā noi kuke a me nā mea kuke, ka mea, e olelo aku nei me ka pono, a ma ke keleawe oihana a pau pono ka hoʻoili hoʻa'ā i mai ke ahi a hiki i ka huina hoonui i hoomakaukauia, a me ka wela ua kōā kaulike haawi ma luna o ka ili i ka hui 'ana me ka lapalapa.

O ka holo ana, nā mea hiki ke hooheheeia, aʻaʻole wale nō ke hooheheeia, hoolilo wela paha,ʻOkoʻa, e komo lawa conductivity, akā, keleawe, ua hiki i kekahi o ka mea pono no laila,-kapaia thermal conductivity kaʻi lau waiwai o ke keleawe o ka lani kiekie loa ma luna wale nō ke kālā.

Na hiohiona nona iho i nā ample kūpono o ka hoʻohana 'ia o metala i loko o nā kula. Ma nā mea a pau keleawe wela mail nenoai ka mea, o ka mea mua moho no ka palapala noi. No ka laʻana, ma Electro maalea a kaa radiator, kahi ka hahana loa coolant loli, oia ke oi aku ka wela.

Ano, e hiki ho'āʻo mea, kena ae la i ka wela hoolilo ia e maopopo. He aha ka mea i hanaia ua wehewehe loa wale. Aia ka heʻaʻahu ikehu hoi o ka makana ma luna o ka buke o ka mea. Oe ke kauo i analogy me ka yiaeaiiacaaeneiie kinoea. Once i loko o ka vicious ipu ia kinoea ninoaaeyao a pau i loaʻa ka lewa. No laila, 'aneʻi, ina o ka mea hiki ke hooheheeia ua enaena ma kekahi wahi, i ka ikehu kūpono ua haawi kōā kaulike ma ka mea.

Oia ka kŰia hiki ke wehewehe ma ka thermal conductivity o ke keleawe. Me ka hele ana i loko o ka quantum ke kālaikūlohea, ka mea hiki ke olelo aku ia ma muli o ia kekahi mawaho ikehu kumu (hahana maoli nō kēia) o na nā'ātoma loaa hou ikehu, a laila,? Aaeaao ia i kekahi'Ātoma. Ka ikehu (wela) Ua haawi ma ka buke o ka mea, e kauoha ana kona nohona ma paio hahana maoli nō. Kēia ka hana i kekahi waiwai.

Ke wale koena unuhi mea i keleawe, a mea he kiʻekiʻe loa thermal conductivity, maikai wela wehe ', a me nā waiwai hana i ka mea he nui loa. Akā, ma na hihia a pau ia i e pono ai ka waiwai. Ma ka waiwai o ka waiwai poorly hoʻomaka wela ma muli'īpale, ma muli o kaʻilihune wela hoolilo 'aʻole i hoʻomaka ai i kona mau poho. Thermal'īpale i ka haleʻo ia ka mea e hiki ai ke malama i oluolu ka noho i loko o ka loa loa aiʻaihueʻia.

Ke kūkaʻi o ka ikehu paha, e like me ia ma ka hihia, wela hoolilo, a me ka hiki e ana o kekahi mea, ina ka mea, i loko o ka hoʻopā aku. 'O kēia ka hana i ka wa a mākou i ka ipu lepo ma luna o ke ahi. He wela, a laila, wela ka wai o ka ipu. Aie i ka mea waiwai o ka wela hoolilo ia lŘlŘ. Heat hoolilo mea kalele iho maluna o na mea he nui aʻe, a me ka waiwai o ka mea ia iho, e like me kona maemae. Penei, ina o ka thermal conductivity o ke keleawe mea maikaʻi ma mua ia o na mea hiki ke hooheheeia, i kona oka a pau, ke keleawe a me ke keleawe i ka me ka nui loaʻuʻuku iho kona waiwai wela conductivity.

Kamailio e pili ana i kēia mau waiwai, ka mea e e hoʻomaopopo i ka thermal conductivity hilinaʻi nui ma luna o ana wela. ʻO ka loa, he keleawe me ka maʻiʻo o 99,8%, e like me ka mea ana wela maoli ka thermal conductivity kulu, a me na mea hiki ke hooheheeia e like me ke keleawe manganese, me ka mahuahua ana wela kaʻi lau waiwai, piʻi pū.

I ka luna ano, ua haawiia ho'ākāka o ka manaʻo like thermal conductivity, wahi a hiki i ka physicalʻike manaʻo, ke kumu hoohalike o ke keleawe a me nā waiwai manaoia kekahi palapala noi o kēia mau waiwai i loko o maʻamau o ke ola.
