Pehea e hoohalike Hawaiʻi: ka anu u ma ka anu u kuhikuhi. He aha nā loina hiki ke hoohalikeia: examples

Mai ka manawa kahiko, kanaka seriously hoihoi i loko o ka ninau o ana he pono e hoohalike na loina i hoike ia ma kekahi mau Hawaiʻi. A me ia mea e pono maoli lanakila. Man kahiko Honua maikai ana i haawi mai ia o kona kulana he paakiki hihia hoʻokahi wale nō mea hiki cia. Pono 'ana i ka lepo, hooholo i ke kaumaha o ka huina hoonui ma ke kuai, e pono e hoʻomaulia i ka lākiō o ka waiwai ma ka'auwaʻa, e hooholo i ka pololei ana o ka hua waina i kaʻohiʻana o ka waina - kēia mau mea wale nō i ka hapa uuku wale no o ka hana i pinepine ia ka' ilikai ma kekahi ano paakiki ke ola o ko kākou mau kūpuna. No laila, i ka poorly hoʻonaʻauao a me ka illiterate kanaka e hoohalike, ina he pono, nā loina hahai i ka'ōlelo aʻo o kona nui inā pilikia ka haumāna hoa, a me ka mea pinepine lawe i ka uku kūpono no keia hana, a me ka nani maikaʻi, ma ke ala.

He aha hiki ke hoohalikeia

I ko makou manawa, i kēia mea, ua haawi mai no hoi i ka nui kūlana i loko o ke ao o ka mea kiko'ī sciences. Ua noa, o ka papa, ua ike ia ia mea pono e hoohalike i ke kumukuai o homogeneous, oa na ohia - Mele a me beets - me beets. O ka mea a me ka makemake loa ho'āʻo i ka hoike Kelekia ma kilomika a kilograms ma decibels, akā, me ka boa lōʻihi Koʻolauloa ua ike mai ke kamaliʻi (no ka poe e ole hoomanao, i loko o hoʻokahi BOA - 38 Koʻolauloa). Oiai Koʻolauloa, hoi, ua okoa, a me ka mea boa lōʻihi, e oko ma ka subspecies o ka Koʻolauloa, akā, i kēia mau mea i loko o lāliʻi a mākou i ho'āʻo i ka ike.

dimensionality

I ka wā i loko o ka 'oihana: "Hoʻohālikelike na loina" pono ia i ua mau loina alakai i ka hoʻomaopopo like denominator, i ua hoikeia ma ka ia Hawaiʻi no ka oluolu o ka nane. Ua mea akaka i ka hoohalike i ke kumukuai, i hoike ia ma kilograms me ka waiwai i hoike ia ma centners a me ka tons, no ka nui o mākou i loko o ka'ōpao. Eia naʻe, loaʻa nō homogeneous mea i hiki ke hoike i ka likeʻole Ana, a, hou, i loko o kekahi ana nenoai. E ho'āʻo, no ka laʻana, hoohalike i nā loina o ka kinematic (viscosity), a hooholo i mea oi ÷ loli ma cSt a kuea mau mika kekona päkahi. Ua 'aʻole e hana? A mai kiʻi. E hana i kēia, nā loina noonoo i ka ia cia, a me ka ua ma luna o ka laulā cia, e hooholo i ka lakou mea i oi i ka hoa paio.

kaʻimiʻana kahua

I mea e maopopo i nā loina hiki ke hoohalikeia, ho'āʻo e hoole i ka na ana nenoaiu. I mea e hoʻoikaika a hōʻeleu i ke ana kaʻina hana i ka 1875, nā'āina (a me Rusia, USA, Germany a me kekahi poe e ae.) Ua kakau inoa ia e ka peni Convention, a hooholoia metric kahua. E hoʻomōhala a consolidate hae o mika a me ka kilogram i hoʻokumu i ka International Komite no paona a me Keia Manawa, a ma Paris, e iai? Oaiaaou i ka International Buro o nā paona a me Keia Manawa. Kēia'ōnaehana e ho'ōla Hawaiʻi i loko o ka System o Units, Si International. Currently, keia'ōnaehana i ua aponoia e ka hapanui'āina i loko o ka mahinaʻai o oaoieei-Me, a me kela mau aina, kahi i hoʻohana mea maʻa mau o ke aupuni, i kela la i keia ola physical mea (e like me kaʻAmelika Hui Pūʻia a me Enelani).

GHS

Eia naʻe, ma ka laua me kaʻike mau olua mau hae, e hoʻoikaika i nā, emi pono CGS'ōnaehana (kenimika-gram-kekona). Ua Ua manaoia i ka makahiki 1832 ma ka German physicist Gauss, a ma ka 1874 hōʻano hou Maxwell, a Thompson,ʻano nui i loko o ke kula o electrodynamics. I ka MH 1889 ka mea i kaumaha aku oi pono MKS'ōnaehana (mika-kilogram-kekona). Hoʻohālikelike nui loa pili waiwai mika a me ka kilogram nā kānakaʻenehana nui oi pono ma mua o ka hoʻohana 'ana o nā mea loaʻa (centi-, milli-, deci- listen'ōlelo.). Naʻe, i kēia manaʻo iʻaʻole i loaʻa i ka papakaukau pane i loko o ka naau o ka poe no ka mea nona ka mea i manao. Ma ke ao nei, 'Imi ke kino a me ka hoʻohana' ia metric'ōnaehana, no laila, ke helu hoʻokōʻia e ka GHS emi emi a, a me ka hope o 1960, a me ka hoʻokomo 'ia' ana o ka Si'ōnaehana, GHS, a 'aʻole kokoke haule i loko o disuse. Currently GHS maoli pili i ka hana pono wale nō ina ka helu i kaʻimi naʻauao mechanics a me astrophysics, a laila, ma muli o ia ka simpler ano hoʻopaʻa 'ia e na kanawai o ka electromagnetism.

I Wa ma ka anu u alakai

E mākou nana ma ka au mamuli o ka laʻana. Ina o ka pilikia o: "oe ke hoohalike i ka waiwai o ka 25 tons, a 19570 kg whichever mea oi aku.?" He aha e oe hana mua mea mea e hooholo i loko o ka Hawaiʻi mākou i haawi mai ai nā loina. No laila, i ke kumukuai mua mākou i hāʻawi aku ai i loko o nā kana, a me ka lua o ka - ma kilograms. Ma ka lua o ka mua, ua kikoo paha mākou e ole ana e komo i ka hookahuli ai i hana compilers, ho'āʻo e kiʻi i ka hoohalike dissimilar nā loina. Aia i kekahi 'oihana-pahele, o ka oi aku i loko o ka kokololio hoao ana, ma ka pane ana i kēlā me kēia nīnau a ua haawi mai no 20-30 kekona. Me mākou ke ike, ka loina iʻaʻahu: ma kilograms a me nā kana mākou i ana ka nuipa a me kino ke kaupaonaʻana, no laila, i ka lua o ka hoao ana ua hala me ka maikaʻi result. Ke kolu o ka mua, unuhi kilograms i ke tona, a, conversely, he tona - i loko o kilograms no ka oluolu o ka nane. Ma keʻano mua huli 25 a me 19,57 tons, a me ka lua: 25 000 a me 19 570 kg. A, ano, e hiki me ka maluhia o ka manao, e hoohalike i ka aiee o kēia mau loina. I maopopo i nanaia, ka mua cia (25 m) i loko o nā hihia, ua oi aku ma mua o ka lua o ka (19 570 kg).

pahele

E like me ka olelo ma luna, ke kālā no e ho'āʻo ai iloko o ka puu o ka hana-bogus. Kēia UaʻAʻole pono wae mākou hana, he pahele hiki e muli o kona kulana noho malie hoi e-huli ninau, o ka oi aku kekahi i begs he Logical pane. Naʻe, i ka perfidy, e like me ka rula, o loko o nā lāliʻi, a ma ka poe uuku nuance i na drafters o ka hana e ho'āʻo ana ma nāʻano a pau i hūnā au. No ka laʻana, kahi o ka he disassembled pilikia me ka hoʻomanaʻo o ka ninau kama'āina oe: "Hoʻohālikelike i ka waiwai ma kahi e mea hiki" - na drafters o ka hoao ana hiki wale noi aku oe i ka hoohalike i kēia mau waiwai, a koho i na loina ia lakou iho e strikingly like i kekahi i kekahi. No ka laʻana, Kg * m / s, a ² m / s ^2. Ma ka hihia mua ia o ka manehu o ka mea (Newtons), a me ka lua o ka - hoʻonui o ke kino, a me ka m / s, a ² m / s kahi au e noi e hoohalike i ka hoʻonui o ka mämä holo o ke kino, i mea ihola ia dissimilar nā loina.

Eia naʻe, nui pinepine i ka hana alakai mau waiwai, i hoike ole wale i loko o kaʻokoʻa naehana a me kekahi mau nenoai o ka ho omaulia, akā, i okoa mai kekahi i kekahi ma ka i Kekahi Mau 'o ka physical manaʻo. No ka laʻana, i loko o ka pilikia hoike ia mai nei: "Hoʻohālikelike na aiee o hōʻeuʻeu, a kinematic (viscosity), a hooholo i mea oi ÷ loli." Nā aiee o kinematic (viscosity) i haawi mai ai i loko o Si huahelu,ʻo ia hoʻi, i loko o ka m ² / s, a me ka hōʻeuʻeu - ka GHS, i mea, ma ka poise. He aha e hana ma keia hihia?

E hoʻoponopono i kēia mau pilikia, e hiki ke hoʻohana i ka luna olelo ao me ka uuku kumukanawai a ia. Mākou hooholo a o na nenoai, e hana: e ia ia i ka Si nenoaiu, mea, he pono ole i waena o nā kānakaʻenehana. Ka lua o ka mua, ke i ka huli, a ike ina mea 'o ka hei ai lakou? Akā, i loko o kēia hana, hoi, a pau ka maemae. Kakou e hoakaka aku i ka mau fluids ke aiao o ka maloko kū'ē ((viscosity)), naʻe nā loina i homogeneous. Ke kolu o ka mua o ka unuhi i ka hōʻeuʻeu (viscosity) o ka poise ma Pascal-lua, i mea ma na huahelu o ka Si nenoaiu. Eia unuhi i ka kinematic (viscosity) i loko o ka hōʻeuʻeu, hoonui ia ma ka AYEIE waiwai o ka wai a nuʻa (papaaina waiwai) a hoohalike i ka hopena i loaa mai ai.

Aia nō i 'ole-Si huahelu, oa naehana i komo i loko o Si, akā, e like me ka hopena o ka mālama' ia ka hālāwai kūkā General hoʻoholo ma luna o paona a me Keia Manawa (GKVM), henua pololei no ka hoʻohana me ka Si. Hoʻohālikelike mau aiee i kekahi i kekahi wale i ka wa e lawe mai ana ia i kekahi, he pono ole ia hoʻi, ke Si hae.
