KVp sawv cev rau dab tsi hauv hluav taws xob?
Dr Francis Deng thiab Dr Ayush Goel et al. Kilovoltage ncov (kVp) yog lub siab tshaj plaws muaj peev xwm siv rau lub x-ray raj, uas ua kom cov electrons los ntawm cathode mus rau anode hauv radiography lossis xam tomography. Tube voltage, nyob rau hauv lem, txiav txim qhov ntau thiab zoo ntawm cov photons generated
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Qhov twg electron configuration sawv cev rau ib tug atom nyob rau hauv nws lub hauv av?
Yog li txhua qhov kev teeb tsa hluav taws xob nyob rau hauv uas lub xeem electron (dua, lub valence electron) yog nyob rau hauv lub zog ntau dua orbital, lub caij no tau hais tias nyob rau hauv lub xeev zoo siab. Piv txwv li, yog tias peb saib hauv av hauv lub xeev (electrons nyob rau hauv lub zog qis tshaj plaws uas muaj orbital) ntawm oxygen, lub teeb tsa hluav taws xob yog 1s22s22p4
