Takamaiman nauyi

Watakila ba dalibai wadanda ba su taba ji da wadannan matsala: "Wanne ya fi sauƙi - kilo na fluff ko kilogram tubalin?". A mafi m abu ne cewa, duk da fi'ili maganar banza, da yawa samu shiga a cikin m shawara. Lokacin da akwai wani rabo a cikin zaman jama'a yi - shi ne ba a sani ba, amma shi za a iya zaci cewa kima na nauyi data na kewaye abubuwa dangane da wani kwatanta su girma halaye da aka sani tun lokacin Archimedes. Specific halaye an gane zama da hali na wasu daga cikin auna dabi'u, misali, da nauyi da kuma girma. Lissafi da rabo daga G da rabo:

G = P / V, da kuma ji naúrar a SI - n / cubic mita.

Weight - wani gwargwado na Duniya ta faduwa kasa, kuma musamman nauyi ga cewa dalilin ba wani jiki halayyar abubuwa, tun da shi ya dogara da wuri na ma'aunai. Mẽne ne ya zama? Ka tuna cewa nauyi P - ne gravitational karfi halayyar filin, wanda ake dangantawa da inertial halaye abu taro m, da hanzari na free fall g. A daya hannun, g - vacillates da kuma dogara, ciki har da, da kuma daga Gwargwadon tsarawa. Tun Newton ta farko dokar P = m * g ne ko da yaushe m, yana yiwuwa a kammala da cewa canzawa daga nauyi a lokaci guda tare da canji a cikin gravitational hanzari.

The classic definition ne: "The share - shine rabo na jiki nauyi zuwa ga girma." Duk da haka, wannan sauki ya ta'allaka quite gwaji rikitaccen - ba daidai ba aikace-aikace raka'a ya jagoranci wani rikice na Concepts game da nauyin da jiki nauyi. Kamar yadda aka sani, tsarin taro naúrar (SI) ne daidai da 1 kg, da karfi a cikin wannan tsarin, bisa ga Newton ta shari'a, shi ne auna a newtons, kuma 1H = 0,102 kg * 9.8 m / sec. sq.

Domin da yawa fasaha aikace-aikace Newton karfi naúrar ne da ɗan m, don haka ko da ya tafi a kan haifar da wani sabon ji tsarin - gravitational awo tsarin. Yana da aka hada da gauraye raka'a ji: mita - kgf - biyu. Abin da ya bada? Yana simplifies da yin amfani da raka'a ikon a hakikanin rai saboda da wannan lamba magana na musamman nauyi da kuma musamman nauyi, watau yawa a cikin daban-daban tsarin, bayar da cewa hanzari g ne akai ko negligible.

Bukatar yin amfani da takamaiman nauyi da'awa a material ganewa fasaha, tabbatar da dalilin da impurities a cikin tsarin ko porosity.

Sanannun hanya domin kayyade samfurin na zinariya, yawa Gems Tsarin, da dai sauransu. Ainihin hanyar da aunawa da musamman nauyi dangane da korar daban-daban embodiments: jiki nauyi da aka auna da kuma, ta hanyar nutsewa a cikin ruwa, ta girma, da sikeli aka ce - kasuwanci kayan aiki. Musamman tasiri ne da yin amfani da data samu a cikin wannan hanya, a cikin binciken na karafa da su gami. Yawanci, a priori da aka sani rabo daga nauyi na karfe da kyau-karatu Properties. Su ainihi tare da sabon model kafa a mutunta mutane da yawa, amma za a fara wani binciken da aunawa da musamman nauyi.

The ruwa amfani ne kullum ruwa, amma ga ma'aunai na high daidaituwa shi na samar da wani babban zaman lafiyar na waje sigogi - zafin jiki da kuma matsa lamba. Wani lokaci, misali, a cikin binciken na amber for jabu amfani da musamman ruwa tare da wani takamaiman nauyin fiye da 2 g / cc.

Specific nauyi ya na asali fasaha kashi a cikin m aikace-aikace na Magnetic ruwaye. Fine-kananzir slurry tare da ferroporoshkom damar Magnetic filin saukin yin wani ruwa tare da m sarrafawa ko preassigned musamman nauyi. Domin irin wannan tsari a kan kafada enrichment na polymetallic ores da yawa da sauran kayan da yawa impurities, wanda yadudduka rabu da wani tsawo daga cikin flotation wanka a tsananin daidai da mutum musamman nauyi. Yana yiwuwa ga irin tsabtace muhalli tama beneficiation fasahar - wani haske nan gaba.
