He aha mea he snowflake? Pehea ka mea, e hana, a mea ia ninoieo o?

Tiny hau nā pōaka pohihihi kūlana ano, a generously haawi mai kela hooilo - e ka mea na snowflakes. I ka mea pohihihi o keia hana mana kupaianaha o ke ano i lōʻihi o Laielohelohe ninau lakou hoomaopopo ana. Pehea i keia kŰia, i kānāwai i hoʻokuleana i ka ikaika aloha o ko lākou mau 'ano apau loa, a no ke aha la ka mea i ai like - kēia mau nīnau, e ho'āʻo i ka pane i loko o kēia' atikala.

I ka moolelo o ka hoʻopaʻa 'ana o snowflakes

ʻepekema, ua ho'āʻo loa e loaʻa mai i nā snowflakes, e wehewehe i ka luna 'a me ka harmonious' ole o ko lākou mau hale mea. I ka mua o ko lākou mau Nails mai maoli e i e ka Hawaiian kanaka noiʻi Mangus i ka 1555.

I ka hoʻomaka o ka XVII kenekulia ka German nä känaka 'epekema Iogann Kepler ikeia ua aneane pau snowflakes i hexagonal nā pōaka. He Ua paʻiʻia ma luna o ke kumuhana o iao? Pepa.

I nā makahiki 1635-1637 i ka ninau o ka snowflakes e hoihoi i loko o ka Palani mathematician Rene Dekarta. He hōʻike nana e like ia me nā līlia, Roses a me nā huila me eono niho ia. He Ua paʻiʻia kā lākou mau sketches, hiki i ka mea au i ike snowflakes me ka umikumamalua ewalu paha niho, a he ike loa kākaʻikahi.

I ka 1885, 'Amelika nä känaka' epekema Wilson Bentley paʻi kiʻi pū i ka mea mua hau aniani ma lalo o ka microscope. No ka aneane kanalima makahiki, i kona ohi ua ma kahi o 5000 like kiʻi paʻi.

Japanese Nakaya Ukitiro - physicist - Ua seriously komo i loko o ke ao o ka Pehea snowflakes e hana a ke kumu ka mea, i nā mea a pau i okoa, i loko o ka 30 makahiki o ka iwakalua kenekulia. He ua lākou mua 'epekema Mea Maluna, a invented keʻano papa hana no ka? Iecaianoaaiiie oʻimi hoʻopunipuni hau. Ka inoa o ka nä känaka 'epekema i kapaia ka Hale Hōʻikeʻike o ka hau, a me ka hau i ka noho ana ma Iapana, ma ka mokupuni o Hokkaido.

I ka 1955, i ka Lūkini A. huakaʻi i ke kai snowflakes māheleʻia i loko o eiwa nā papa, e like me 48? Ueo. Iwaena o lakou - "hedgehogs", "kui kele ma", "Una", "kī", "cuff nā loulou" a me na mea e ae.

'Amelika Kenneth Liebrecht e noho ana i loko o kēia mau lā, ua "piha o snowflakes Akanahe." I kona keʻena hoʻokolohua, e ulu artificially hau nā pōaka, ia mea a hiki hiki, e haawi aku i ka manao shape.

Pehea e hana snowflakes

Snowflakes i hana mai ka wai mahu. Tiny droplets o haʻahaʻa ka mahana, a kiʻekiʻe humidity ua Punk i loko o nā ao. Lakou alo i ka lepo (particles) lana ana i loko o ka lewa, a hui ia. Penei, i ka i komo snowflakes, - i ka lepo huna (aniani nuclei) a me ka meaʻuʻuku hau (particles), ke kiʻekiʻe o ulu puni kela mea keia mea o lakou.

Like wā e hiki mai snowflake hina i ka honua, ka mea hui a pau o ka hou hau nā pōaka, oiai hoʻokoe iho i kona maopopo hexagonal shape. Convex apana o ke aniani, e ulu wikiwiki.

Pilikia ma ke alanui me supercooled droplets, snowflake mau i ka ulu. Hiki ole i kekahi pilikia nui, e hina ia - ma ka honua.

ʻano o nā snowflakes

Ma ko lakou ulu ana i ke ala snowflakes i hana, a pehea, ka mea e loli ai kini aʻe. Ka loa nui o ia mau mea - ka alternation o ka mahana i loko o kekahi papa o ka lewa, e lawe mai hau nā pōaka e kekahi.

I ka lewa, i ka snowflakes i mau hoʻololi. Ma anu? Eou nā pōaka ulu ua accelerating, ko lakou ulu ana nunui ma ka lōʻihi. Aia, he mea oi mehana, kekahi o ka "kukuna" hooloihiia, akā, hoʻomaka e mahuahua ma ka laulā. Ike ana i ka snowflake, e hiki wale no ke aha la, ke kaumaha ma muli ino kumu i loko o ka ua wahi ana, e hina ia typical no kona 'ano o ka hau wehewehe.

No laila, i loko o ka Baltic aina, a Central Rusia i ka malie ino, he hau pinepine hele mai i loko o ka palapala o ka nui "fluffy" flakes, a i ka luna 'ai manamana palapala. Me nā pā maila ikaika o ka makani a me ka haahaa wela snowflakes collide i kekahi i kekahi, a me ka popopo i loko o ke olonā i ke koena ai haule e kō ana. Inā 'oe hit me kanaha-degere anu, ka nascent hau nā pōaka e hūnā i ka honua "daimana lepo". A ma ka waenakonu o Yakutia i anu ino haule pinepine lahilahi "kui kele ma" o ka hau.

I ka wā o ka hau, e hina ia

Snow ua hana i loko o ka hihia, i ka wa o ka lewa mahana mea ma lalo mau kekelē Kelekia. Ka manaʻo i kēia ana wela mea e haule iho ma lalo Aʻohe - mea he nā kaʻao. Ma keia hihia, e hoʻomaka e maule i ka hau i mua haule. Naʻe, i loko o ke kaʻina ea mahana i loko o nā wahi ma kahi e, aia no na precipitates pono emi.

Heaviest hau flakes hāʻule i loko o ka laulā o ka 'Aʻohe i nā degere. Akā, inā i ka mahana, e ala luna, a laila, i ka mea, he o snowflakes - uuku hau nā pōaka, e inexorably hehee. Ma keia hihia, loa paha, mākou e manaʻo haule pulu hau, a me ka ua.
