Kev sib cais cov isotopes yog qhov tseem ceeb rau kev tsim cov uranium nplua nuj siv rau hauv kev tsim hluav taws xob lossis cov isotopes kho mob uas pab hauv kev kuaj mob thiab kho cov kab mob. Cov roj centrifuges muab ib txoj hauv kev zoo thiab pheej yig rau kev sib cais isotope, ua rau nws tsis tseem ceeb hauv cov cheeb tsam no.
III. Kev Ua Haujlwm Sab Hauv ntawm Cov Tshuab Centrifuges Roj
Cov roj centrifuges muaj ib lub rotor cylindrical uas tig nrog kev kub ceev, muaj ntau qhov chaw rau kev sib cais roj. Lub rotor feem ntau yog ua los ntawm cov khoom siv muaj zog, sib dua xws li carbon fiber reinforced polymer kom tiv taus cov zog loj heev thaum lub sijhawm ua haujlwm.
Sab hauv lub rotor, muaj cov raj me me, txhua lub muaj cov qauv roj. Thaum lub rotor tig, qhov sib txawv ntawm qhov hnyav molecular ua rau cov molecule txav mus rau qhov tob dua ntawm lub raj vim yog lub zog centrifugal. Los ntawm kev tswj hwm cov qauv tsim thiab qhov ceev tig, kev sib cais cascade tuaj yeem ua tiav, sau cov roj ntawm qhov hnyav molecular sib txawv ntawm ntau qhov chaw raws lub rotor.
IV. Cov Kev Siv ntawm Cov Pa Roj Centrifuges
Cov roj centrifuges pom muaj kev siv rau ntau qhov chaw vim lawv muaj peev xwm hloov pauv tau yooj yim thiab ua haujlwm tau zoo. Cia peb tshawb nrhiav qee qhov chaw tseem ceeb uas siv roj centrifugation:
