Ngumlingani lokwanda kumgama - kunokwenzeka ukuba ukubala zonke

Wonke Urhashaza phezu ngokuqinisekileyo aziqhelileyo amavili buyo. Okanye isandi kweevili tram. Wonke umntu uyazi ukuba isizathu umsantsa apho kudibana phakathi naLindiili. Kwaye yintoni ke ukuba wenza? Impendulo ilula - ukuze kubuyekezelwe ukwandiswa ngololiwe xa itshiswe. Oku kwakhona Yinyaniso eyaziwayo ukuba ngexesha ubushushu lomzimba ukwandisa nciphisa xa zipholile. Ngumlinganiselo oku kwanda okanye nokuncipha kuphindwe inomlingani lokwanda yomgama.

Theory Ezinto yokwandiswa lomzimba xa itshiswe ngenxa yokwanda isantya yokuhamba-athom kunye iimolekyuli. Ngenxa yoko, Ilibele ukungcangcazela awo athom ukunyuka, kwaye ngenxa yoko - ukwandisa Ubukhulu linear umzimba. Kwaye aya kunyuka, icaciswa usebenzisa ifomula, esebenzisa inomlingani lokwanda yomgama.

Ngoku ke kufuneka ukuba uchaze intsingiselo ebonakalayo kwezi ingumlingani. Ubonisa indlela yokwandisa xa itshiswe 1 ° C ubude yomzimba. Ixabiso le emfutshane kwaye eyahlukileyo izinto ngalinye. Ngenxa yoko, ukwandiswa inani yomgama sobhedu 0.000011 1 ° C. Yintoni Kwandile ixabiso onjalo kuqondwe umzekelo olula. Ukuba Umhlaba ikhweyitha wire urhangqo asisinyithi ubude ngu 40,000 km, kuyanda ubushushu nge-1 ° C uya kwandisa ubude locingo kwi iimitha ezingama-400.

Ukwanda lomlingani yomgama kubaluleke kakhulu ngenxa yaso nasiphi na engineer. It ikuvumela ukuba uthathe ingqalelo utshintsho kubungakanani lobushushu emzimbeni drop. Ngoko ke, ukuba kwisithuba sonyaka ubushushu esixekweni ukutshintsha ukusuka dibanisa amahlanu degrees Celsius thabatha mahlanu degrees Celsius, oko kuya kubangela utshintsho olukhulu ngobude naLindiili efanayo. Ukuba eqinileyo, umphumo uya kuba ukugoba wabo. Oko kukuphepha into enjalo kwaye wenze umsantsa phakathi yimiqolo ngexesha icebo labo.

Ngokuba izinto ezahlukeneyo ziya kwahluka ixabiso ingumlingani. For steel ixabiso sele ezibonisiweyo, nokongezwa lomlingani ngokulandelelanayo ye-aluminiyam iya kuba 0.0000024 1 ° C.

Nangona kunjalo, i ingxoxo thaca kunye nemizekelo ubunzima obuthile-sidedness enye. Xa sithetha ukunyusa ubungakanani umzimba xa itshiswe, ukwandisa kuphela ubude, kodwa ezinye imilinganiselo - ubude nobubanzi. Ukunyuka ubukhulu kuya kukhokelela ekwandeni umthamo, yaye ngoko ke sithethe ukwandiswa umthamo imizimba. Inyaniso yingcamango kunokuba ayisayi kusebenza eziqinileyo kunye ezingamanzi.

Into elula eya kuqinisekisa oku, wonke umntu angenza ezabo. Beka iketile phezu komlilo, ezaliswe ngamanzi ukuya phezulu. Xa amanzi ukufudumala, oko lokongeza umthamo "ukubaleka" ukusuka iketile. Kodwa kukho ukusetyenziswa positive yale isiphumo. Yinto eyaziwayo ithemomitha lulwelo - leyo ukuba zonyango. Nabo, kakhulu, nakhelwe phezu isiphumo yokwandisa umthamo xa itshiswe.

ngamanye amaxesha ndlela uzibe enjalo ukwanda ikhokelela neziphumo ezimaxongo. Ukuze kubuyekezelwe sokwanda kuyimfuneko ukusebenzisa iindlela ezizodwa. Abaninzi baye babona uthotho elide yemibhobho (line) wayibeka phezu komhlaba. Kwaza ngequbuliso ngaphandle ityhubhu eluhlaza ukuba ibe nale enkulu. Oku akuthethi nale elula, ixabiso layo ichazwa ngqo, ukubala yaba umlinganiselo kusetyenziswa lokwanda yomgama. Kufana umgca amajikojiko ukuze kubuyekezelwe kukwanda ubukhulu kumbhobho.

Uyakwazi futhi ukunika imizekelo emininzi ukusetyenziswa ubuchule lokwanda yomgama kunye ngokomthamo, kodwa le mizekelo Kwanele ukuqonda kakuhle isenzeko. Kakade ke, ukwazi kakhulu ukuziphatha anomalous kwezinto ezithile, loo manzi. Eqina xa umthamo akuthethi ndinciphe ke ukunyuka. Le yenye into engqina iimpawu ezizodwa zamanzi.

Ngoko ke, kweli nqaku ngokusekelwe imizekelo elula ezichaza nobomi nomqondo onjalo njengoko kuchaziwe yi-linear ukwandiswa eziqinileyo kunye nemicwe nokwandiswa ingumlingani. Imizekelo yokusetyenziswa ukwandiswa kubuchwepheshe kunye kubomi bemihla ngemihla, banikwe ingqiqo ngokomyalelo ubukhulu ingumlingani utshilo.
