Cov Net Energy Ratio lossis NER ntawm lub zog thev naus laus zis yog siv los qhia tias 'ntau npaum li cas' uas siv tshuab yog nyob rau hauv cov nqe lus ntawm kev muab zog rau haiv neeg. Yog li cov piv nruab nrab ntawm tus nqi ntawm zog yuav tsum tau ua lub vaj huam sib luag thiab cov zog nws generated yog 3.2.
Yog li ntawd, net zog suav li cas?
Net zog yog tus nqi tag nrho zog koj lub tsev ntshuam los ntawm lossis xa tawm mus rau daim phiaj hluav taws xob. Net zog yog xam los ntawm rho tawm zog tsim los ntawm koj lub hnub ci zog system los ntawm zog siv los ntawm koj lub tsev.
Ib sab saum toj, Eroei yog dab tsi thiab nws suav li cas? EROEI yog xam los ntawm faib lub zog tso zis los ntawm lub zog input. Kev ntsuas tag nrho cov zis hluav taws xob feem ntau yog ib qho yooj yim, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv rau ib qho hluav taws xob tso zis qhov twg qee qhov ntsuas hluav taws xob tsim nyog siv tau.
Xav txog qhov no, qhov sib piv ntawm lub zog ntawm lub hnub ci yog dab tsi?
Yog hais tias nws yuav siv 8 units ntawm zog kom muaj 10 units ntawm zog , tiam net - zog piv yog 10/8 los yog 1.25.
Net - Zog piv.
| Zog Source | Net-zog ratio |
|---|---|
| Hnub Ci Zog | 5.8 |
| Natural Gas | 4.9 |
| Roj av | 4.5 |
| Coal-fired Hluav taws xob | 2.5-5.1 |
Net zog yog dab tsi thiab vim li cas nws tseem ceeb?
Tus nqi siv tau zoo heev zog muaj los ntawm ib tug muab kom muaj nuj nqis zog kev pab yog nws net zog yield: tag nrho cov txiaj ntsig zog muaj los ntawm ib tug zog Resource rho tawm zog yuav tsum tau ua kom muaj rau cov neeg siv khoom.

Dab tsi yog qhov muaj zog thiab qaug zog acid piav nrog piv txwv?
Cov kua qaub muaj zog sib cais (sib cais) tag nrho hauv dej). Piv txwv li, HCl, cov kua qaub muaj zog yuav tawg mus rau H + thiab Cl-ions. Cov acids tsis muaj zog dissociate ib nrab hauv dej. Piv txwv li, HF, cov kua qaub tsis muaj zog, tsuas yog yuav muaj qee yam ntawm HF cov molecules sib cais thaum twg los tau
Txoj cai twg yog txhawm rau muab lub zog saib xyuas muaj zog ntxiv dag zog rau kev ua txhaum cai lij choj tiv thaiv kev ua phem thiab tiv thaiv kev lag luam nyiaj txiag?

Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov?
Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov? Qhov kawg qhov chaw yuav yog lub hnub
Piv txwv li, muaj zog acid thiab qaug zog acid yog dab tsi?
Piv txwv ntawm cov acids muaj zog yog hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) thiab sulfuric acid (H2SO4). Cov kua qaub tsis muaj zog tsuas yog qee qhov sib cais, nrog rau ob qho tib si undissociated acid thiab nws cov khoom dissociation tam sim no, nyob rau hauv kev daws, nyob rau hauv equilibrium nrog ib leeg
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
