Hoʻomaopopo i ka Conductivity: Ka wehewehe a me ka mea nui

Hoʻolauna

He kuleana koʻikoʻi ka conductivity i nā ʻano like ʻole o ko mākou ola, mai nā mea uila a mākou e hoʻohana ai i kēlā me kēia lā a hiki i ka hāʻawi ʻana i ka uila ma nā pā uila. He mea koʻikoʻi ka hoʻomaopopo ʻana i ka conductivity no ka hoʻomaopopo ʻana i ke ʻano o nā mea hana a me ko lākou hiki ke hoʻouna i ka uila. Ma kēia ʻatikala, e ʻimi mākou i ka wehewehe ʻana o ka conductivity, e ʻimi i kona koʻikoʻi, a nānā i kāna mau noi ma nā ʻano like ʻole.

He aha ka Conductivity?

ʻO ka conductivity kahi ana o ka hiki o kahi mea ke hoʻokele uila. ʻO ia ka waiwai o kahi mea e hoʻoholo ai i ka maʻalahi o ke kahe uila e hiki ke hele i loko. He ʻano koʻikoʻi ka conductivity o nā mea he nui a hoʻohana nui ʻia i nā ʻano ʻepekema a me ka ʻenekinia.

Ma keʻano laulā, he mau mea hoʻokele uila maikaʻi nā metala no ka mea he helu kiʻekiʻe lākou o nā electrons manuahi e hiki ke neʻe i loko o ka mea. ʻO ia ke kumu i hoʻohana pinepine ʻia ai ke keleawe a me ka alumini i nā wili uila a me nā noi uila ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, ʻo nā mea e like me ka ʻōpala a me ke aniani nā mea hoʻokele maikaʻi ʻole o ka uila no ka mea ʻaʻole nui nā electrons manuahi.

Hiki ke ana 'ia ka conductivity o kekahi mea ma ke ano o kona pale uila. ʻO ke kū'ē uila ke kū'ē i ke kahe o ke au uila ma o kekahi mea. ʻO ka haʻahaʻa o ke kūpaʻa, ʻoi aku ka kiʻekiʻe o ka conductivity. Ana pinepine ʻia ka conductivity ma Siemens no ka mika (S/m) a i ʻole millisiemens ma ke kenimika (ms/cm).

Ma waho aʻe o kona hoʻohana ʻana i nā noi uila, koʻikoʻi ka conductivity i nā ʻano ʻē aʻe e like me ke kemika, biology, a me ka ʻepekema kaiapuni. No ka laʻana, hiki ke hoʻohana ʻia ka conductivity o ka wai e hoʻoholo ai i ka neʻe ʻana o nā paʻakai i hoʻoheheʻe ʻia a me nā mea ʻē aʻe i loko o ka wai. He mea nui kēia ʻike no ka hoʻomaopopo ʻana i ka maikaʻi o ka wai a no ka nānā ʻana i nā kūlana kaiapuni.

Nui nā kumu e hiki ke hoʻopili i ka conductivity, e like me ka mahana, ke kaomi, a me ke alo o nā haumia a i ʻole nā ​​​​mea ʻē aʻe i loko o ka mea. I kekahi mau hihia, hiki ke hoʻonui a hoʻomalu ʻia ka conductivity ma ka hoʻohui ʻana i kekahi mau mea i ka mea. ʻIke ʻia kēia he doping a hoʻohana maʻamau ʻia i ka ʻoihana semiconductor e hana i nā mea me nā waiwai uila kikoʻī.

He waiwai koʻikoʻi ka conductivity o nā mea he nui a he koʻikoʻi koʻikoʻi i ka nui o nā noi ʻepekema a me ka ʻenekinia. He mea nui kona ana a me ka hoomalu ana no ka hoomaopopo ana a me ka hooipoipo ana i ka hana o na nenoai a me na hana like ole.

Hoʻokaʻawale a me nā mea hoʻokele uila

ʻO ka conductivity kahi ana o ka hiki o kahi mea ke hoʻokele uila. He waiwai koʻikoʻi ia ma nā ʻano he nui, ʻo ia hoʻi ka ʻenekinia uila, ka ʻepekema waiwai, a me ka physics. ʻO nā conductors nā mea me ka conductivity kiʻekiʻe, ʻo ia ka mea e ʻae lākou i ke kahe uila e kahe maʻalahi ma o lākou.

I ka ʻenekini uila, ʻo ka conductivity kahi mea nui i ka hoʻolālā ʻana o nā kaapuni uila. Hoʻohana ʻia nā mea me ka conductivity kiʻekiʻe e like me nā conductors uila, aʻo nā mea me ka conductivity haʻahaʻa e hoʻohana ʻia e like me nā insulators. ʻO nā mea hoʻokele uila maʻamau he mau metala e like me ke keleawe a me ka aluminika, he kiʻekiʻe ka conductivity ma muli o kā lākou mau electrons manuahi.

Hoʻohana ʻia nā mea me ka haʻahaʻa haʻahaʻa, e like me nā plastics a me nā seramika, e like me nā insulators e pale aku i ke kahe uila ma o lākou. Hoʻohana ʻia nā insulators i nā ʻano noi like ʻole, me nā wili uila, nā ʻāpana uila, a me nā laina hoʻoili mana.

I ka ʻepekema waiwai, he waiwai nui ka conductivity no ka hoʻomohala ʻana i nā mea hou. Ke ʻimi mau nei nā mea noiʻi i nā mea me ka conductivity kiʻekiʻe no ka hoʻohana ʻana i nā ʻano noi like ʻole, me ka mālama ʻana i ka ikehu a me ka hoʻololi ʻana, nā uila, a me nā ʻike.

ʻO kekahi o nā kumu nui e pili ana i ka conductivity ʻo ka mahana. Ke piʻi aʻe ka mahana, emi ka conductivity o ka hapa nui o nā mea. ʻO kēia ma muli o ka piʻi ʻana o ka haʻalulu wela o nā ʻātoma i loko o ka mea, ʻoi aku ka paʻakikī o nā electrons e neʻe i loko o ka mea.

ʻO kekahi kumu e pili ana i ka conductivity ʻo ka hele ʻana o nā haumia i loko o ka mea. Hiki i nā haumia ke hoʻopau i ke kahe o nā electrons ma o ka mea, e hōʻemi ana i kona conductivity.

Conductivity Ana Units

He mea koʻikoʻi nā ʻāpana ana conductivity o kēlā me kēia kaʻina hana ʻoihana e pili ana i ka hoʻohana ʻana i nā wai. ʻO ka conductivity kahi ana o ka hiki o kahi wai ke hoʻokele i ka uila, a he mea koʻikoʻi ia i ka hoʻoholo ʻana i ka maikaʻi a me ka maʻemaʻe o ka wai. Hana ʻia ke ana conductivity me ka hoʻohana ʻana i nā mea hana kūikawā i kapa ʻia ʻo nā mita conductivity, i hoʻolālā ʻia e ana i ka conductivity uila o kahi wai.

Hōʻike maʻamau nā ʻāpana i hoʻohana ʻia e ana i ka conductivity ma Siemens no ka mika (S/m) a i ʻole micro Siemens ma ke kenimika (μS/cm). Hoʻohana ʻia kēia mau ʻāpana e hōʻike i ka conductivity uila o kahi wai, ʻo ia ke ana o ka nui o ka uku uila e hiki ke lawe ʻia e ka wai. ʻOi aku ka kiʻekiʻe o ka conductivity uila o kahi wai, ʻoi aku ka nui o kona hiki ke hoʻokele uila.

Ma waho aʻe o nā ʻāpana maʻamau o ke ana, hoʻohana ʻia nā ʻāpana ʻē aʻe e hōʻike i ka conductivity. Loaʻa kēia mau mililisiemens ma ke kenimika (mS/cm), like me 1000 μS/cm, a me nā hoʻoholo no ka mika (dS/m), like me 10 S/m. Hoʻohana ʻia kēia mau ʻāpana i nā noi kikoʻī kahi i kūpono ʻole ai nā ʻāpana maʻamau.

ʻO ke koho o nā ʻāpana ana conductivity e pili ana i ka noi kikoʻī a me ka pae o ka pololei i makemake ʻia. No ka laʻana, hoʻohana mau ʻia ka micro Siemens per centimeter i nā mea kanu mālama wai, ʻoiai ʻo Siemens i kēlā me kēia mika ke hoʻohana ʻia i nā kaʻina hana e koi ai i nā pae kiʻekiʻe o ka pololei. ʻO ke koho ʻana o nā ʻāpana e pili pū ana i ke ʻano o ka wai e ana ʻia, no ka mea, ʻokoʻa nā pae wai like ʻole o ka conductivity uila.

He mea koʻikoʻi nā ʻāpana ana conductivity o kēlā me kēia kaʻina hana ʻoihana e pili ana i ka wai. ʻO ke koho o nā ʻāpana e pili ana i ka noi kikoʻī a me ka pae i makemake ʻia o ka pololei.Nā mika conductivityua hoʻolālā ʻia e ana i ka conductivity uila o nā wai, a ʻo nā ʻāpana i hoʻohana ʻia e hōʻike i ka conductivity ʻo ia ʻo Siemens no ka mika, micro Siemens ma ke kenimika, millisiemens ma ke kenimika, a me nā hoʻoholo no ka mika.

Nā noi o ka Conductivity

ʻO ka Conductivity, ka hiki o kahi mea e hoʻokele i ke au uila, he ākea ka nui o nā noi ma nā ʻano like ʻole. Eia kekahi mau hoʻohana maʻamau o ka conductivity:

Uea uila: He mea koʻikoʻi ka conductivity no nā ʻōnaehana uila. ʻO nā metala e like me ke keleawe a me ka alumini, i ʻike ʻia no ko lākou conductivity kiʻekiʻe, hoʻohana mau ʻia i nā kaula uila e hoʻouna pono i ka uila mai nā kumu mana i nā mea like ʻole a me nā mea hana.

Hoʻohana ʻia nā hāmeʻa electrolytic, i loaʻa i nā ion e hoʻomaʻamaʻa i ke kahe ʻana o ka uila, i nā noi e like me ka electroplating, nā pā, nā wahie, a me ka electrolysis no nā kumu ʻenehana a me ka ʻepekema.

Nā Nani a me nā ʻIke: Hoʻohana ʻia ka conductivity i nā mea ʻike a me nā mea ʻike no ke ana ʻana i nā waiwai uila. No ka laʻana, hoʻohana ʻia nā mea ʻike conductivity e nānā i ka maʻemaʻe o ka wai i loko o nā mea kanu mālama wai a ʻike i nā loli o ka conductivity e hōʻike ana i nā haumia a i ʻole nā ​​​​mea ʻino.

Nā Lapaʻau Lapaʻau: Ma ke kahua o ka lāʻau lapaʻau, loaʻa ka conductivity i nā noi ma nā wahi e like me nā ana bioelectric a me nā ʻenehana kiʻi olakino. ʻO ka Electrocardiography (ECG), no ka laʻana, e ana i ka conductivity uila o ka puʻuwai e ʻike a nānā i nā kūlana naʻau.

Mea Hoʻohui: Hoʻohana ʻia nā mea hoʻohui hoʻohui i ka hana ʻana i nā mea hoʻohui e hāʻawi i ka conductivity uila. Loaʻa kēia mau mea i nā noi i nā ʻoihana like ʻole, me ka aerospace, automotive, a me ke kūkulu ʻana, kahi e koi ʻia ai ka conductivity no nā noi e like me ka pale electromagnetic, static dissipation, a me nā mea wela.

Nānā Kaiapuni: Hoʻohana ʻia ka conductivity i nā ʻōnaehana nānā kaiapuni e loiloi i ka maikaʻi o ka wai a me ka paʻakai. Hoʻohana ʻia nā mita conductivity e ana i ka conductivity uila o ka wai, e hāʻawi ana i ka ʻike waiwai e pili ana i kona haku ʻana a me nā mea haumia.

He mau hiʻohiʻona wale nō kēia o ke ʻano o ka hoʻohana ʻana i ka conductivity i nā kahua like ʻole. ʻO nā waiwai uila kūikawā o nā mea conductive e hiki ai i kahi ākea o ka holomua ʻenehana a me nā hana hou ma nā ʻoihana he nui.
