Txiav txim siab koj lub tuam txhab Bonding Capacity . Bonding peev yog qhov nyiaj ntau tshaj ntawm cov credit credit ib lub tuam txhab muaj tseeb yuav muab rau tus neeg cog lus. Nws yog feem ntau hais nyob rau hauv cov nqe lus ntawm qhov loj tshaj plaws ib qhov project qhov tseeb yuav txaus siab rau qhov teeb meem thiab qhov siab tshaj plaws ntawm daim ntawv cog lus backlog tus neeg cog lus tuaj yeem tuav.
Kuj tseem paub yog, tus neeg cog lus lub peev xwm sib koom ua ke yog dab tsi thiab nws txiav txim siab li cas?
Cov kev sib txuas muaj peev xwm tsuas yog cov txheej txheem uas txiav txim siab seb koj yuav ua haujlwm li cas lossis ua haujlwm txuas ntxiv mus txog thaum koj tau txais koj cov nyiaj them rau kev ua haujlwm tau cog lus, feem ntau nyob ib ncig ntawm 60-90 hnub.
Tsis tas li ntawd, dab tsi yog qee yam uas cuam tshuam rau tus neeg cog lus lub peev xwm sib cog lus? Muaj tseeb daim ntawv cog lus tuam txhab tshuaj xyuas ob peb yam ua ntej muab ib tus neeg ua haujlwm sib cog lus muaj peev xwm . Cov no yam suav nrog tab sis tsis txwv rau lub tuam txhab lub zog nyiaj txiag thiab muaj cov credit, keeb kwm ntawm tuam txhab nyiaj, cov qhab nia credit, cov ntaub ntawv qhia txog kev ua haujlwm, kev ua haujlwm tam sim no thiab lub zog nyiaj txiag ntawm cov neeg sib tw ze.
Tsuas yog li ntawd, kev sib koom ua ke hauv kev tsim kho yog dab tsi?
A kev tsim kho daim ntawv cog lus yog hom kev ruaj ntseg daim ntawv cog lus siv los ntawm investor nyob rau hauv kev tsim kho tej yaam num. Kev tsim kho bonds yog ib hom kev ruaj ntseg daim ntawv cog lus uas tiv thaiv kev cuam tshuam lossis kev poob nyiaj txiag vim yog tus neeg cog lus tsis ua tiav qhov project lossis tsis ua raws li cov lus cog tseg.
Lub peev xwm sib txuas ntawm oxygen yog dab tsi?
Muab ob npaug rau covalent daim ntawv cog lus Kho O muaj qhov valency ntawm 2, nrog 6 electrons, xav tau 2 ntxiv kom ruaj khov (txawm tias oxygen muaj 6 electrons, nws muaj valency ntawm 2 vim nws tsuas xav tau 2 ntxiv rau stability).

Dab tsi yog qhov sib npaug rau tam sim no muaj peev xwm sib txawv thiab tsis kam?
Equations Equation Symbols Meaning in words I = Δ V R I = dfrac{Delta V}{R} I = RΔV I Kuv yog tam sim no, Δ V Delta V Δ V yog hluav taws xob muaj peev xwm sib txawv, thiab R yog tsis kam Tam sim no ncaj qha proportional rau hluav taws xob muaj peev xwm sib txawv thiab inversely proportional rau kuj
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
Dab tsi yog lub luag haujlwm ntawm ATP hauv kev sib txuas lus sib txuas?
ATP coupling tso cai rau cov tshuaj tiv thaiv uas xav tau lub zog tshwm sim los ntawm kev siv lub zog tso tawm hauv kev hloov pauv ntawm ATP mus rau ADP kom lub zog tas li ntawm cov tshuaj tiv thaiv
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
