115 tau daig hauv lub cov hlwb tuag thiab xaus rau restarting lawv. Leej twg muaj 115 nyob rau hauv lawv lub cev yuav tsum ceev faj, rau thaum lawv tuag lub 115 yuav reanimate lawv lub cev. Nws yuav taug kev los ntawm lawv lub hlwb mus rau tag nrho lawv lub cev, mus txog rau 115 yog nyob rau hauv txhua cell.
Yog li, puas muaj lub ntsiab lus 115?
Tam sim no, nyob ntawd yog 114 lub ntsiab lus hauv Lub Sij Hawm Lub Sij Hawm. Ob lub ntsiab lus tshiab, flerovium (atomic number 114) thiab livermorium (atomic number 116), tau ntxiv rau Lub Sijhawm Teev Ntuj hauv xyoo 2012. Element 115 tam sim no hu ua ununpentium, uas tsuas yog ib qho chaw mus txog thaum nws lub npe raug tsim.
Koj puas tuaj yeem txhim kho lub caij 115? Cov kws tshawb fawb hauv Sweden tau lees paub qhov muaj nyob ntawm nqe 115 . Nws nyob ib ncig ntawm lub sijhawm ntev heev. Cov kws tshawb fawb ntseeg tias nws tuaj yeem coj lawv los ze zog rau lub mythical "kob ntawm kev ruaj ntseg" tag nrho ntawm kev hnyav hnyav. cov ntsiab lus uas ua tau kav rau hnub los yog xyoo.
Ntxiv mus, dab tsi tuaj yeem siv 115 rau?
Siv ntawm moscovium Tsuas yog ob peb atoms ntawm moscovium puas tau ua, thiab lawv tsuas yog siv hauv kev tshawb fawb. Nws yog siv ua nihonium.
Lawv ua li cas 115?
Qhov hnyav tshaj plaws keeb Hauv qhov xwm txheej yog uranium, uas muaj 92 protons. Tab sis hnyav dua cov ntsiab lus -uas muaj ntau protons nyob rau hauv lawv cov nucleus-tuaj yeem tsim los ntawm nuclear fusion. (Related: Kawm yuav ua li cas ua ib keeb .) Cov neeg tsim 115 yog thawj zaug tsim los ntawm cov kws tshawb fawb Lavxias hauv Dubna txog kaum xyoo dhau los.

Puas yog tag nrho cov hlwb puas muaj peev xwm ua kom lub cev so?
Yuav luag tag nrho cov plasma daim nyias nyias muaj lub peev xwm hluav taws xob hla lawv, nrog rau sab hauv feem ntau tsis zoo nrog rau sab nraud. Hauv cov hlwb uas tsis yog excitable, thiab hauv cov hlwb excitable hauv lawv cov hauv paus ntsiab lus, lub peev xwm membrane yog tuav ntawm tus nqi ruaj khov, hu ua lub peev xwm so
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas cov hlwb muaj peev xwm sib txuas lus nrog lwm cov hlwb tseem ceeb?
Cov kev sib cuam tshuam no tso cai rau cov hlwb sib txuas lus nrog ib leeg hauv kev teb rau kev hloov pauv hauv lawv cov microenvironment. Qhov kev muaj peev xwm xa thiab tau txais cov teeb liab yog qhov tseem ceeb rau kev muaj sia nyob ntawm tes. Kev sib cuam tshuam ntawm cov hlwb tuaj yeem ruaj khov xws li cov uas ua los ntawm cov xov tooj ntawm tes
Puas muaj peev xwm equilibrium zoo ib yam li so muaj peev xwm?
Qhov sib txawv ntawm daim nyias nyias muaj peev xwm thiab qhov muaj peev xwm sib npaug (-142 mV) sawv cev rau lub zog hluav taws xob hluav taws xob uas tsav Na + mus rau hauv lub xovtooj ntawm lub peev xwm so membrane. Thaum so, txawm li cas los xij, qhov permeability ntawm daim nyias nyias mus rau Na + tsawg heev kom tsuas yog me me Na + xau rau hauv lub cell
