Rau txhua tus neeg, rho tawm lub sijhawm tawm ntawm Cov Sijhawm Ua Haujlwm Net, thiab muab cov txiaj ntsig los ntawm nws qhov muaj kom tau txais nws tus kheej muaj peev xwm . Ntxiv rau tus kheej lub peev xwm kom tau txais Pab neeg muaj peev xwm nyob rau hauv tus neeg teev, thiab faib los ntawm yim kom tau lub muaj peev xwm nyob rau hauv tib neeg-hnub.
Tsuas yog li ntawd, koj yuav suav li cas pab pawg muaj peev xwm?
Pab neeg muaj peev xwm yog ib yam khoom ntawm tag nrho cov naj npawb ntawm Scrum pab neeg cov tswv cuab sib npaug los ntawm tus lej ntawm pab neeg cov hnub tsim khoom. Nov yog ib qho piv txwv ceev rau kev qhia meej: Yog tias koj qhov nruab nrab sprint story point yog 32, thiab koj muaj 6 pab neeg cov tswvcuab uas muaj sijhawm ua haujlwm (8 teev / hnub).
Ib tug kuj yuav nug, dab tsi yog pab pawg muaj peev xwm hauv agile? Hauv kev tswj hwm qhov project ib txwm muaj, muaj peev xwm yog tag nrho cov sij hawm uas ib tug neeg, los yog pab neeg , yuav tsum ua haujlwm. Hauv scrum, muaj peev xwm yog tus nqi ntawm cov khoom backlog cov khoom uas a pab neeg tuaj yeem txaus siab rau lub sijhawm lub thawv tsis tas yuav mus rau kev ua yeeb yam.
Ib yam li ntawd, koj yuav suav li cas muaj peev xwm?
Txoj Kev Yooj Yim: Tag Nrho Cov Ntau Lawm Thaum Lub Sij Hawm Ib Lub Sij Hawm Ib txoj hauv kev yooj yim tshaj plaws rau ntsuas muaj peev xwm tsuas yog siv tag nrho cov khoom kom muaj nuj nqis rau ib lub sijhawm. Piv txwv li, yog tias koj cov nroj tsuag tuaj yeem tsim qhov nruab nrab ntawm 20, 000 gizmos ib lub lim tiam, ces koj tag nrho muaj peev xwm yog 20,000 gizmos ib lub lis piam.
Yuav ua li cas npaj muaj peev xwm xam nyob rau hauv agile?
Hauv paus ntawm Agile peev xwm npaj yog ib qho yooj yim kev sib npaug : Tus naj npawb ntawm cov neeg koom tes tau muab faib los ntawm cov hnub hauv kev sib tw ua haujlwm tau muab faib ua cov sijhawm ua haujlwm tau zoo hauv ib hnub.

Yuav ua li cas hydrogen bonding ntawm cov dej molecules pab piav qhia dej lub peev xwm nqus tau ntau lub zog ua ntej evaporation?
Cov hydrogen bonds hauv dej tso cai rau nws nqus thiab tso tawm lub zog cua sov qeeb dua li ntau lwm yam khoom. Qhov kub thiab txias yog ib qho kev ntsuas ntawm qhov kev txav (kinetic zog) ntawm cov molecules. Raws li cov lus tsa suab nce, lub zog yog siab dua thiab yog li kub siab dua
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
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
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
