Anisotropy - He aha ka keia? Paa a me ka noi

He 'atikala mai nei i ka anisotropy - i ka like ole o kekahi physical nui aiee ma kekahiʻaoʻao o ka puaʻa hiwa paʻa. E hōʻike ana i ka mea e hookomo anisotropy, kahi e kō, pehea e pili. I pokole ho'ākāka ka anisotropy ololi.

Hoʻoholo 'ana o ka anisotropy

E mākou hoʻomaka me ka ho'ākāka 'ana o kēia manaʻo. Anisotropy - kēia likeʻole ma waena o ka waiwai a me ka mea kiko'î o ka mea i loko o kekahiʻaoʻao. Ua huli iki incomprehensible, aʻae nō hoʻi pono wehewehe. Ma lalo o ka waiwai ke ano o kekahi waiwai ano - kohoʻia, kani māmā holo, refractive inideka, thermal conductivity, uila conductivity. Ke'ōlelo mai, no ka laʻana, no ka kani māmā holo anisotropy - mea he kŰia ka wā transversely Kaulu pü nä hawewe kani i kekahi okoa māmā ma mua ma. Ma keia hihia, ua waiwai e kokua, e kuhikuhi i ka laha ',' ia i loko o ka hohonu o ka honua i ka pńpa. A maoli palena manawa o ke olai, no kekahi laʻana, a me ka pela i hana ikaika loa, e haawi aku i ka manaʻo o ka pa apŘ, a me ka huina o ka hanana o okoa nā minelala hao.

Ke anisotropy Ua ka manawa?

Ma ka hoohiki ana o ka manawa pinepine pili ia i ka anisotropy o ke aniani. Kēia māhele epa me ka ke kālaikūlohea o ka puaʻa hiwa. A me kekahi haumana o ke akamai oi loa ike i ka waiwai o ka waiwai hilinai ole wale ma luna o ka mea o ka mea ia ua i mai o nā'ātoma, akā, i ka mea a me ka māhele ma waena o kēia mau nā'ātoma i pili. A me ka hapanui o importantly, ka mea, e kalele iho ma luna o ka symmetry pae o ka kūpono 'ole. A huina o kanakolu-elua. Ke symmetry pūʻulu hōʻike mai ana i na mea he nui, a ka neʻe i e hana i ka mea ia hehee wale i superimposed a coincide loa. Mau hana ioiinyony: ke kuapo e pili ana i ka iho (axis) (ma ka kekahi huina), manaʻo ma ka pelane, a wahi hahana. Symmetry pūʻulu a me ka hōʻike mea e ia i ka anisotropy o nā pōaka. Waiwai me ka cubic 'ole, no ka laʻana, mai lilo keia waiwai. Kiko'î a ua puaʻa hiwa i ka ia i loko o nāʻaoʻao.

He aha huina mea e pono ai ka anisotropy?

Ma luna o mākou i hāʻawi aku lakou i mea hoike, i ka wa a ka propagation o ke kani nei i ka ia i loko o ae transverseʻaoʻao. He He kūikawā hihia o ana, e hoike i ka anisotropy o ka waiwai, a ua kapaia ka manawa "orotropiya". Naʻe, i ka symmetry o ke aniani mea ole wale he cubic paha rhombic. He trigonal ia lŘlŘ hou mall hehee wale ka wā haliu ae la ia ma luna o ke kolu o ka hoa kanaka, a me hexagonal, oiai ke kuapo huina mea like i kekahi ke ono o ka p ÷ ai. Ke symmetry o ka haahaa waeʻano, monoclinic, mau hiʻohiʻona nō ka waiwai e e e lauwili i loko o ke aniani i loko o ekolu ae ÷ hakuʻaoʻao. Penei, anisotropy - kona mea e like mea pōaka puaʻa hiwa, i hiki ke hoike mai ai ia ia iho i kekahi huina i loko o kekahi pelane, a ma ke Keena Kalaiaina.

Mai na waiwai a pau e i anisotropy?

Kēia ninau mea Logical. Inā kekahi waiwai i loko o keia aniani mea anisotropic, ina nā mea kiko'î e hahai hoopii? Ponoʻole. E lawe, no ka laʻana, nā pōaka, a i hoʻohana i ka po hihio na manao ona. e hiki ke hoʻolilo i kaʻike makaʻole welaʻula kukui i loko o ka hiki huahelu ka mea, (pinepine loaa i kekahi kiʻi o kekahi mau malu o ka uliuli). Ma kēia mau mea, i ka anisotropy - he kumu o ka waiwai i mea pono no ka hoʻohana a me ka hiki e maikaʻi kēia. A, i ka hookoia e ia mea maikaʻi, nā nā pōaka E e ke ka ao ma ka hoʻoholo ma mua huina (no keia mea, ua hōʻike hewa ulu i loko o ka kekahi alanui). Ma nā wahi o ka pāhawewe huli ana i emi ole ma nā mea a pau paha. Ma keia hihia, ke thermal conductivity, ka mämä holo o ke kani , a me electrodiffusion ka mea, pili uniformly i loko o nāʻaoʻao. Ua hoi ka hana i kekahi waiwai oko ao o kona ano huina kekahi i kekahi, a - kekahi. Akā, ia mea he mea lahaʻole hihia.

Where'ē aʻe o ka anisotropy?

A i kekahi kanaka lohe i ka "nā pōaka" IeAUPIIe, IAa IO imagines translucent kaola o ka pōaka a ametuseto. Kekahi mau kaikamahine paha manaʻo e pili ana i Jewelry. Naʻe, i ke aniani i e kekahi paa. Products i ka hao, Aluminum, keleawe, ke tina, hoi, iloko o nā pōaka, akā, loa uuku. A i loko o kēlā i kēia mau mea ma ke anakahi iki kiʻekiʻe mea i nānā mau anisotropy o ka mea hiki ke hooheheeia. Eia naʻe,ʻo ka waiwai, a i haawi i loko o ka p ÷ haku kuhikuhi ma na aoao, loa kekahi, a me ka maʻamau o ke ola unnoticed. No ka laʻana, ma cubic nā pōaka o ka hao a me ka Aluminum Young ka moduli o elasticity lauwili me ka i koho iho (axis). A laina anoe o ka piuta kekahi ma kekahiʻaoʻao aneane papalua. Eia naʻe, ua lāliʻi ka mea, IeAUPIIe, IAa IO i koi 'ia e noonoo i kela lā. Ma hope o nā mea a pau, i ka anisotropy o ke hooheheeia a me kona hopena i ana i waiho ai i loko o nā mea a pau i ko lakou hiki ana i ka manao kahua o nā mea a pau, na hale, airplanes, hana.

Pehea e hoʻomaulia i ka anisotropy?

Na mea a pau i kākau ma luna, ke manao nei e hai aku i ka mea heluhelu, ua maopopo lawa i keia anisotropy. Eia naʻe, he mea kekahi ninau: Pehea e ho omaulia pehea waiwai ma ka divergent LIKE i loko o ka'ā? No keia mea i ke kaʻi lau waiwai o anisotropy. Outset no kēlā me kēia waiwai ka mea, he pōpilikia okoa. Nā hoailonaʻike piʻi anisotropy paha e okoa mai kekahi i kekahi. A me mechanical waiwai o quantum nenoai OAOOUIEeE fundamentally, i mea oluolu i kekahi i ka mea'ē aʻe e e impracticable a hiki ole. Nolaila, e kamailio e pili ana kekahi, he pono ole i kekahi nui ololi mea i pono. Eia hoʻi, ia pinepine pōpilikia theoretically ole e hiki, wale keia nui ua loaa ia empirically. anisotropy kaʻi lau waiwai nui maupaʻa ka lākiō o nā loina aʻo i loko o kekahiʻaoʻao. I kekahi manawa, i kēia huahelu nō ka huina ma waena o ke kohoʻaoʻao. Eia naʻe, pinepine wale me he anakahi ma ka lalo o ka nui. No ka laʻana, K _xy Hōʻike i keia lākiō pili ia i ke koena unuhi o ke kino nui aiee ma ka X a me y me na koilipi.
