Njengoba izinhlobo frost? amaphethini egqamile ebusika

LeAnn kubhekwe lo mkhuba enhle kunazo yemvelo. Lakhe elikhazimulayo ubukhazikhazi kanye filigree amaphethini enchants nathi ukuphelela yayo, futhi izimbongi futhi abaculi iphefumulelwe ukudala imisebenzi amahle.

Kuyini frost?

Amazolo ayiqhwa - ingenye uthi yamanzi (umusi), okuyinto kwe0 ° C uguqulwe ube ungqimba ezondile ice crystalline. iphethini ngayinye engavamile yayo futhi eyingqayizivele.

into enjalo alichaza yokuthi ukubaluleka ezahlukene lokushisa lokususa akalingani kuthinta kumiswa ice crystal nesakhiwo. Yingakho rime nesithwathwa ubukeka ezahlukene njalo. Lapho izinga lokushisa lehla ngezansi zero, ice zinhlayiya babe olunezinhlangothi ukuma-nezibhebhe. Nge frost ngokulinganisela (kufika ku -15 ° C) kukhona ukubukeka kwayo zifane ipuleti unxande. Futhi uma izinga lokushisa kakhulu ngezansi -15 ° C, bese ice crystal livela ngesimo izinaliti blunt.

Kuphi futhi kanjani amafomu frost?

Frost kwenzeka ezintweni ezahlukene kanye evele lapho selehlile lokushisa negative ngaphansana lokushisa air. Lokhu kwenzeka ngenxa umhwamuko desublimation - okusho ukuthi ingena isimo okuqinile, ngaphandle kokudabula isigaba liquid. ungqimba Frost ngokwanele ezacile, kanye inqubo Ukwakheka engalingani.

Ukutadisha kumiswa frost, abacwaningi wafinyelela esiphethweni ukuthi inani elihle kunawo salokhu zasebusuku umoya ukukhanya noma cha. ngokuvamile Lokhu kwenzeka ngasekuqaleni kwentwasahlobo, ukuwa ngasekupheleni noma ebusika lapho ungqimba emoyeni e-surface eqhukethe umhwamuko.

Kulezi zimo ngesimo selitulu saseBhetlehema ngaleso evele ahlukahlukene anolaka kokuba conductivity encane ezishisayo, njengaleyo i ekhanyayo, utshani, ebhentshini sokhuni, zemithi, uphahla nezinye ekhanya ngempela ubonakala ungqimba. Njengoba frost amafomu kulezi evele? Lokhu kungenxa yokuthi i- umusi epholisa, iphenduka iqhwa zinhlayiya esihle. Futhi amandla amancane emoyeni nakakhulu kusiza le nqubo ngokubuyekeza ezinomswakama emoyeni mass.

Isihlahla Cover - frost nesithwathwa?

Frost ezihlahleni kuyinto umdlalo ejabulisayo. Buka ezimhlophe isihlahla elikhazimulayo futhi izihlahlana ushiya akekho ngabandayo. Lapho empeleni kungukuthi ukufukamela frost kanye frost. Ukuze ongelutho elula, le miqondo emibili ayafana, kodwa ososayensi babe ngokuqinile yabo ehlukile. Ngaphandle ukuthi frost kwakhiwa ngenxa umhwamuko desublimation, le nqubo ithatha indawo kuphela ezingeni lokushisa ngezansi -15 ° C khona inkungu. Ngaphezu kwalokho, it is nje imbozwe into mncane eside ezifana wire, negatsha zasemazweni.

Ngakho-ke, i-frost izihlahla kusuka Ngokombono ongokwesayensi - it is kuphela embozwe iqhwa zinhlayiya ngemiboko yazo. A ezimhlophe amagatsha ingubo - frost. Nakuba, uma Ngiyaqonda ukuthi lo mehluko, okubaluleke kakhulu, muhle!

Amaphethini ku emafasiteleni

I Winter sika Tale - indlela esicabanga nenkathi ebandayo. Ayini umhlobiso kuphela akasebenzisi ebusika. Rime esiphambili kuzo okumnandi kakhulu. Ngaphezu kwalokho, bonke ubuhle bayo kubonakala amaphethini ku emafasiteleni. Ayegcwele amanzi umusi emoyeni selehlile at 0 ° C no ngezansi, kuphumele ukufingqa umswakama ngokweqile emafasiteleni ebandayo. Kube ngenyanga kubo kanye nokunye ngomuthi - amanzi esimweni ezikuso umusi, ngokudlula esigabeni ketshezi ludlulele okuqinile, kuphenduke iqhwa crystalline.

Yiziphi amaphethini frost?

Ngokuqinisekile sinake quirkiness futhi okwakhe nesithwathwa "imidwebo." Nature udonsa frost amaphethini enjalo, okuyinto zingaphezu esandleni umculi sobudala. Kungani kumiswa frost ingilazi iwindi kuholela wobuciko ezifana? Isizathu ukuthi aweve elula - uhlevane, imihuzuko kanye maholoholo ingilazi uqobo. Phela, nabo basuke kwakhiwa frost is kwasekuqaleni. Oluvelayo, ice zinhlayiya sengathi ahlukaniswe ku nomunye futhi sifake umlingo wama lace. Futhi ukubasiza othulini kuxazululwe phezu amafasitela, kanye notshwala emoyeni.

Phakathi ezihlukahlukene amaphethini frost kuyizinto ezivamile ezimbili izinhlobo - trihity futhi dendrites.

Trihity zifane Imicu obuphelele ezahlukene kanye nosayizi. Basuke kwakheka kwi ingilazi, embozwe imihuzuko ezincane. Okokuqala, isithwathwa kwenzeka kubo njengoba crystalline emapheshana. I ephansi izinga lokushisa kuba njalo, yilapho lo mugqa base iqala siphambuke Imicu yotshani kolweni lwalugobile.

Njengoba izinhlobo frost ngesimo dendrites, okuyizinto ifomu isihlahla-like? Le nqubo kwenzeka phezu ingilazi iwindi, Ukupholisa eyaqala at zero lokushisa, futhi baqhubeka njengoba umba. Ngaphezu kwalokho, umswakama kuleli cala kumele kwenyuke. Okokuqala, ingilazi embozwe ifilimu ezimanzi, okuyinto aqoqana ngaphezulu ingxenye yalo ephansi. "Izinti" amaphethini akhiwa kunalokho enkulu, anyuke ingilazi iba mfushane futhi izacile.

Blame umswakama Ngakolunye uhlangothi, it iyasha kusukela umkhiqizo futhi, ngakolunye, engena ekamelweni ngesikhathi kuvulwa umnyango esiqandisini.

imihlola Abaningi emangalisayo futhi enhle adalwe nemvelo. Kufanele uvumelane, ngaphandle ezitaladini ekuseni e nesithwathwa sezulu ebusika, ungakwazi ukujabulela imiklamo umbukwane zidalwe ne frost.
