Ichando uye kubva kupi chii chinoitwa chando?

Chando chechando - ichi ndicho chinhu chinonyanya kukosha pane zviteshi zvekudenga zviri kumaodzanyemba kumativi ehemisphere. Kutenda kuwanikwa kwezvigadzirwa zvakasiyana-siyana zvinogadzira chando chakadaro, unogona kuita iyi yechando apo yaisati yaonekwa. Muenzaniso wakajeka weizvi unogona kushanda seOlimpiki muSochi, nokuti pasina chando chekushanda, hazvingaiti kutora makwikwi echando mukati memaodzanyemba. Uye nhasi tichapa nyaya yakasiyana pane ino. Saka chii chando chando chinoita ?

Izvi zvinogadzirwa nekupfira mvura mumhepo. Muchiitiko ichi, mvura yacho inoshandiswa mumutambo pasi pekumanikidza. Nokudaro, nucleation process inowanikwa, apo makirasi emvura anowedzera mumhepo uye nokudaro anogadzira chando chechando. Izvo zviyero zvekristasi idzi zvisingabatsiri zvishoma uye zvinotangira kubva ku1 0.1 kusvika ku 10 microni (1 micron is 0.001 mamita).

Ichando chokugadzirira chii?

Gadzirai mahwendefa echando pane mamwe madonhwe emvura. Somugumisiro, makristani makuru emafuta echando. Ivo vanofanirwa kusvikira vapedzisa mugwagwa kubva mukanini kusvika kumusoro kwenyika. Nguva ino yakakwana kuti uwane chando chengwaru. Pamba, hongu, iwe haugone kuumba "yakakosha". Ichokwadi ndeyekuti pamabasa akadaro emichina yehuchenjeri inoshandiswa, inokosha mazana emakumi ezviuru zveRubles. Uye iwe unogona kuumba chando chekuita nemaoko ako pachake kubva pamapepa epepa kana pamba yekotoni, nokuti kutengwa kwemidziyo yakadaro ichange isingabatsiri.

Nekuda kwekuti makristasi eatomized liquid ashandise zvizere panguva yechando ichiita, achiwira pasi, zvakakwana kushandisa chigadziri ichi pamhepo yekupisa ye -3 kusvika kune -10 digrii Celsius. Pachishuva ichi, mvura inoshandiswa zvakanaka inopisa uye inofukidzwa nehutano hwakakwana hwechando.

Kuvapo kwekanyunyuti kunowedzera mukana wechando yakagadzirwa. Nehomwe yega imwe itsva yemvura yakasvibiswa, unowedzera huwandu hwechando (mumaminitsi mashomanana iwe unogona kuisa masheita masendimita makumi maviri). Uye iyo nucleator inogona kubudisa zvose zvisikwa zvipenyu (somuenzaniso, granules jecha, maminera uye guruva particles) uye magetsi (musanganiswa wemvura uye mweya wakamanikidzwa) uye zvehupenyu, chero zvipi izvo izvi zvigadzirwa zvinounza huwandu hwakawanda hwekristasi nehuwandu hwehuwandu hwemvura.

Chii chinobudiswa?

Tatoongorora kuti chando chinoshandiswa chinobva kupi, uye chakawana kuti izvi ndezvikamu zviviri zvepanyama-mvura nemhepo. Uye izvo iyo nucleator inotendeuka nezvinhu zviviri izvi inonzi makriststals. Mumashoko akajeka, madonhwe maduku emvura anobhururuka kunze kwekanoni, iyo inosviba nyore nyore paanopisa -3 degrees Celsius. Mukuwedzera, nuclei yezvimwe zvikamu zvinotarisa zvakasikwa, sezvo iine nucleus yenguva yemberi yekristini yakatangwa. Panguva imwecheteyo, chando chakaita sechinhu chinonyanya kunetseka kune utachiwana hwakanaka. Sezvo izvi zvikamu zvisingakwanisi kupikisa kupisa, pamhepo inotonhora ye 0 uye kupfuura madigiri inongonyauka, uye nokukurumidza zvikuru. Nenzira, kubva pamubhiti rimwe mamita emvura unogona kukwira kusvika 2-2.5 cubic mamita echando chaiyo.

Chii chinogadzirisa kunaka kwekristasi yakabudiswa?

Ichando chechando chichave chehupamhi hwepamusoro uye kusagadzikana nekushandurwa kwekushisa kunotsamira zvakananga nekudzvinyirira kwemvura yakagadzirwa muchando chechando, chigadzirwa chezai yekushandisa uye, hongu, mhepo inopisa uye kupisa kwemhepo pachayo.

Saka, munyaya yatakanyatsoongorora kuti chando chinopihwa chakaitwa, chii icho chave nacho.
