Ekolu-dimensional wa o ka mea ao

Ekolu-dimensional makahiki o he geometric kükohu o ko ke ao nei i loko o kākou e ola nei. Ekolu-dimensional, ka mea, ua kapaʻia no ka mea, o kona ano hoʻopili like i ekolu pa alima vectors kaʻaoʻao ma ka lōʻihi, a me ka laula kiekie. Pokole o ka ekolu-dimensional la, ua ka ulu 'ana o ka loa i na makahiki, a ua pololei e pili ana i ka ōhumu o ke kanaka. Ka hohonu o kona pokole hilinaʻi nui ma ka hiki ana o pilikia makapō naauao o ko ke ao nei, a me ka hiki, e kuhikuhi i na Ana ekolu me ke kōkua o nā makaukau.

E like me analytic anahonua, ekolu-dimensional makahiki ma kēlā me kēia wahi ua ho'ākāka 'ia ma ka ekolu characterizing mea, i kapaʻia wahi. i kahi kūlike o koʻi lipi i mea p ÷ haku i kekahi i kekahi, ke kuʻina wahi hoolilo i ka ho omaka ana, me he 'Aʻohe waiwai. Ke kūlana o kekahi wahi ma ka makahiki i ho'ākāka 'pili i ekolu koʻi lipi me he okoa laulā cia ma kēlā hoʻoholo ma mua wā mawaena. Ekolu-dimensional makahiki i loko o kela a me keia o kona kumu i ua ho'ākāka 'ia ma ka ekolu huahelu e like me ka mamao mai ka olua wahi i loko o kela a me keia i kahi kūlike o (axis) a hiki i ka lae o ka kuʻina me ka hoʻoholo ma mua pelane. Aia mau no hoi ia i kahi kūlike o noaia me ka spherical a me ka paukūʻolokaʻa nenoai.

I ka laina hōʻailona helu, i ka manaʻo o ka ekolu-dimensional ana ua ho'ākāka 'ia ma ma ka manaʻo o ka laina kūʻokoʻa. Helu makahiki o ekolu-dimensional no ka mea, i ke kiekie o ka mea, aole ia i hilinaʻi ma luna o kona laula a me ka lōʻihi. Ma ka 'ōlelo o ka laina hōʻailona helu mai la, he ekolu-dimensional no ka mea, kēlā kanaka wahi mea hiki e hooponoponoia ia mea, mai ka huihui' ana o ka ekolu vectors i mea linearly kuokoa mai kekahi i kekahi. Ma keia hoʻomanaʻo, i ka manaʻo o ka wa-manawa o eha-dimensional waiwai, no ka mea, o ka oihana o ka wahi i loko o kekahi manawa o ka manawa, aole ia i hilinaʻi ma luna o kona wahi i loko o ka lewa.

Kekahi waiwai a mea o ka ekolu-dimensional kahua, kachesvenno oko mai ia mau hakahaka i mea i loko o nā Ana. No ka laʻana, he knot nakinakiia ma kekahi kaula, ua noho ia ma ka lalo ana. Ka hapa nui o ke kino ai 'kānāwai pili i ka ekolu-dimensional Ana o ka makahiki, no ka laʻana, ke inverse huinahalike kānāwai. I ekolu-dimensional makahiki i e elua-dimensional, hoʻokahi-dimensional a me ka 'Aʻohe-dimensional kahua, oiai ia iho ua manaoia hapa o ka kükohu eha-dimensional ka lewa.

Isotropy o ka makahiki,ʻo ia kekahi o kona ki waiwai ma ka panina mechanics. ua kapaia Isotropic kahua no ka mea, i ka wa a kaʻapuni maopopo kahi ponoi ma kekahi ākeʻakeʻa kumu huina EUIAaIN ka ana hualoaʻa mea i hanaia. Ke kānāwai o ka mālama o angular momentum ua ma muli o ka isotropic waiwai o ka makahiki. Kēia 'o ia hoʻi i loko o nā makahiki o nāʻaoʻao i kau like, a he mea i ho'ākāka' ia ka wehewehena o ka olelo me ka kuokoa symmetry iho (axis). Isotropy i ka ia physical waiwai i hiki a pau kuhikuhi. Penei, ka isotropic hookahi - e Aloha ia he 'ia, i ke kino ai ka waiwai o ka mea e ole hilinaʻi ma o ka olelo.
