Beam ibhalansi: Managing

Igama elithi "esikalini 'inezincazelo eziningi futhi kubangela izinhlangano zabantu ezihlukahlukene. abathandi Astronomy cishe uyazibuza mayelana iKhima, ababhula ngezinkanyezi - uphawu zezinkanyezi, futhi iningi ukushaywa oluzayo esitolo noma emakethe ngoba igilosa. Nge nesilinganiso isisindo, siyaqhubeka ebhekene ekuphileni kwethu kwansuku zonke futhi musa noma ucabange ukuthi umlando kule divayisi lasendulo futhi kude kangakanani umuntu ekupheleleni kwakhe.

Uyini izikali ibhalansi

Uma umbuzo yokukukala nenqwaba yiziphi izimpahla noma izithako zamakhemikhali ngokuvamile ukucabanga rocker encane amabili itshali (izinkomishi) kanye umcibisholo, omunye okuyinto ibekwe isisindo emzimbeni okuyinto edingekayo ukunquma, njengoba yesibili - isisindo okuvamile, futhi sifinyelele zilingana yabo. Ukulinganisa encane mass esetshenziswa ravnoplechnye izikali, kwidivaysi omkhulu wezimpahla isetshenziswa nge isihlobo offset kuya isigwedlo maphakathi (odnoplechnye futhi neravnoplechnye isigwedlo ibhalansi).

Umlando omncane

Ucabangani uma abantu beveza kudivayisi sokulinganisa mass? Abavubukuli wahlanganyela lapho kumbiwa ezindaweni eziningi eMesophothamiya, bakholelwa ukuthi ugongolo ibhalansi uqala ukuvela eminyakeni eyizinkulungwane ezinhlanu BC. Futhi kukhulunywa okokuqala ebhaliwe kule divayisi satholakala "Encwadi Mert" yaseGibhithe lasendulo, eyabhalwa cishe 1250 BC. Izinkulumo idokhumenti mayelana ravnoplechnom ijoka unkulunkulu Anubis esetshenziselwa ukuhlola inhliziyo efile. Ohlangothini lokuqala isikali kwaba statuette esibonisa unkulunkulukazi waseGibhithe wobulungisa, Maat, futhi inhliziyo yesibili zazifile. Umphumela sisindvo semikhakha enjalo sincike isiphetho umphefumulo; ekuhleleni kabusha of "ubulungisa" nenkulumo ethi, yena uya ezulwini, futhi enhliziyweni yayo pereveshivaniya kulindeleke ekuhlushweni esihogweni. Ravnoplechnye ugongolo silinganisele nasekufezeni kabanzi eBabiloni lasendulo. Empumalanga yeTurkey is namanje walondoloza Kamennaya Stella (yokuqala yeminyaka BC), oluveza umHeti, usebenzisa umunwe wakho esikhundleni sohlelo rocker. Ngemva kwalokho, ubufakazi obungokomlando kusikisela ukuthi ukuze sithole sabantu usuqalile usebenzisa isimiso esisha, esakhiwa ngo ukusetshenziswa izinsimbi yeselula iphuzu esinqunyiwe inzuzo ukwesekwa. Izikali, umshayo, isakhiwo esisha uvele eRoma lasendulo, futhi ube pair of izibambo hook emise izikali ezimbili. Omunye amathuluzi wokuqala walolu hlobo itholwe yasePompeii. Ngo-12 AD leminyaka nososayensi Arab ngimazi imishini isisindo, iphutha kuvunyelwe ka 0.1%, okuyinto ingasetshenziswa culling imali yomgunyathi, izinto zokuhloba nezindwangu kuncuma ukuminyana zemizimba.

Ukunqunywa mass besikhathi sethu

Naphezu kweqiniso lokuthi electronics ezweni lanamuhla uya esikhundleni umakhenikha nokuxhumanisa luseyintandokazi futhi ngokuvamile lisetshenziselwa ukucacisa mass. Nokho, izikali yezokwelapha, laboratory, commercial, yezobuchwepheshe, yokusebenza ngaphandle kokusebenzisa electronics Sekuyisikhathi eside kunikezwa indlela amathuluzi yesimanje futhi ujike kancane e kwakudala. Ubuchwepheshe ithuthukiswe esikhathini sethu ngokushesha kangangokuthi mhlawumbe abazukulu bethu bazokwazi ukubona izisindo ezimnandi zakudala kuphela ngayo eminyuziyamu. Nokho, kithi uphawu esikalini uyohlale ibukeke izinkomishi ezincane ezimbili elenga rocker kancane mncane.
