He aha ka manaʻo o Mv i ka uila?
Nā mea
Ma ke ʻano he uila e aʻo ana i kekahi mau haumāna, ʻike wau i nā poʻe he nui e huikau ke ʻike lākou i ka huaʻōlelo "MV" a me ke ʻano o ia mea i loko o kahi kaiapuni uila. No ka mea hiki ke manaʻo i kekahi mau mea, e nānā wau i kēlā me kēia o lākou ma lalo nei.
Hiki iā MV ke kū no kekahi o nā mea ʻekolu i ka uila.
- Megavolt
- Volta ma waena
- Milivolt
Ma lalo e wehewehe au i nā wehewehe ʻekolu a hāʻawi i nā laʻana o kā lākou hoʻohana.
1. Megavolt
He aha ka Megavolt?
ʻO ka megavolt, a i ʻole "MV," ʻo ia ka ikehu i loaʻa i kahi ʻāpana i hoʻopiʻi ʻia me hoʻokahi electron i ka wā e hele ai i kahi ʻokoʻa kūpono o hoʻokahi miliona volts i loko o kahi moena.
Ke hoʻohana nei i ka megavolt
Hoʻohana ʻia lākou i ka lāʻau lapaʻau no ka mālama ʻana i ka maʻi kanesa, nā neoplasms a me nā maʻi maʻi e ka lāʻau radiation radiation waho. Hoʻohana ka poʻe loea oncologists i nā kukuna me ka laulā uila o 4 a 25 MV e mālama i nā maʻi maʻi maʻi hohonu i loko o ke kino. ʻO kēia no ka mea hiki i kēia mau kukuna i nā wahi hohonu o ke kino.
ʻOi aku ka maikaʻi o nā hihi X-megavolt no ka mālama ʻana i nā maʻi koko hohonu no ka mea e emi ana ka ikehu ma mua o nā photons haʻahaʻa haʻahaʻa a hiki ke komo hohonu i loko o ke kino me ka haʻahaʻa o ka ʻili.
ʻAʻole maikaʻi ka Megavolt X-ray no nā mea ola e like me nā kukui X orthovoltage. Ma muli o kēia mau hiʻohiʻona, ʻo ka megavolt x-ray ka mea maʻamau i hoʻohana ʻia i nā ʻenehana radiotherapy hou e like me IMRT.
2. Volta uila
He aha ka Voltage Medium?
I ka hapanui o nā hihia, pili ka "volta waena" (MV) i nā ʻōnaehana hoʻolaha ma luna o 1 kV a maʻamau a hiki i 52 kV. No nā kumu ʻenehana a me ka hoʻokele waiwai, ʻaʻole i ʻoi aku ka nui o ka volta hana o nā ʻoihana hoʻoili uila waena ma mua o 35 kV.
Ka hoʻohana ʻana i ka uila uila
Nui nā hoʻohana ʻana o ka volta waena a e ulu wale ana ka helu. I ka wā ma mua, ua hoʻohana nui ʻia nā voltage papa waena no ka hoʻouna lua a me ka hāʻawi mua ʻana.
Hoʻohana pinepine ʻia ka uila uila i nā mea hoʻololi hoʻoili mana e hoʻohaʻahaʻa i ka volta haʻahaʻa i nā lako mana ma ka hope o ka laina. Eia kekahi, hoʻohana nui ʻia i ka ʻoihana no nā kaʻa me ka volta o 13800V a i ʻole.
Akā ua hiki i nā topologies ʻōnaehana hou a me nā semiconductor ke hoʻohana i ka uila uila i nā ʻoihana uila uila. Eia kekahi, kūkulu ʻia nā ʻenehana hoʻolaha hou a puni ka uila uila AC a i ʻole DC e hana i kahi no nā kumu ikehu hou a me nā mea hoʻohana.
3. Milivolts
He aha ka millivolts?
ʻO Millivolt kahi ʻāpana o ka mana uila a me ka ikaika electromotive i ka International System of Units (SI). Ua kākau ʻia ʻo Millivolt e like me mV.
ʻO ka ʻāpana kumu o millivolts ka volt, a ʻo ka prefix ʻo "mili". ʻO ka prefix milli mai ka huaʻōlelo Latin no "tausani". Kākau ʻia e like me ka m. Milli he mea helu o hoʻokahi tausani (1/1000), no laila ua like ka volt me 1,000 millivolts.
ʻO ka hoʻohana ʻana o Millivolt
ʻO Millivolts (mV) nā ʻāpana i hoʻohana ʻia no ke ana ʻana i ka volta ma nā kaapuni uila. Ua like ia me 1/1,000 volts a i ʻole 0.001 volts. Ua hoʻokumu ʻia kēia ʻāpana i mea e maʻalahi ai nā ana maʻalahi a e hōʻemi i ka huikau ma waena o nā haumāna. No laila, ʻaʻole hoʻohana pinepine ʻia kēia poloka ma ke kahua o ka uila.
ʻO ka millivolt ka hapa tausani o ka volt. Hoʻohana ʻia ia e ana i nā voltage liʻiliʻi loa. Hiki ke hoʻohana nui kēia i ka hana ʻana i nā kaapuni uila kahi e paʻakikī loa ai ke ana ʻana i nā volta liʻiliʻi.
E hōʻuluʻulu
He kahua paʻakikī a loli mau ka uila. Manaʻo wau ua kōkua kēia ʻatikala e pane i nā nīnau e pili ana i ke ʻano o Mv i ka uila.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- ʻEkolu mau hōʻailona makaʻala no ka hoʻonui ʻana i ke kaapuni uila
- Pehea e ana i ka volta DC me ka multimeter
- Pehea e ho'āʻo ai i ka mea hoʻololi uila haʻahaʻa
