Cov txheej txheem tawm yog cov txheej txheem lossis cov kev cai uas yuav tsum tau ua kom tiav ib txoj haujlwm lossis txheej txheemraws li siv hauv qee qhov kev lag luam lossis kev tshawb fawb, xws li software engineering.
Cov txheej txheem tawm hauv kev sim yog dab tsi?
Txoj Cai Tawm Tsam yog txheej txheem uas txiav txim siab tias qee yam ua tiav lossis tsis tau. Nws yog ib feem ntawm txoj kev sim. Qhov kev ntsuas no txheeb xyuas yog tias tag nrho cov kev xeem tau raug ua tiav, yog tias tag nrho cov qib yuav tsum tau ua tiav, yog tias txhua qhov chaw tau raug sim, thiab lwm yam.
Qhov twg hauv qab no yog qhov piv txwv ntawm cov txheej txheem tawm?
Piv txwv ntawm Kev Cai Tawm:
Txheeb xyuas yog tias Txhua qhov kev sim tau npaj tau ua tiav. Tshawb xyuas seb qhov kev pab them nqi kho mob puas tau tiav lawm. Txheeb xyuas yog tias tsis muaj qhov cuam tshuam loj heev lossis qhov tsis zoo uas tseem tshuav. Txheeb xyuas yog tias txhua qhov chaw muaj kev pheej hmoo siab raug kuaj tag.
Yuav ua li cas rau kev tawm mus?
Cov txheej txheem tawm mus yog ib qho xwm txheej uas yuav tsum tau ua ua ntej kaw ib theem ntawm tus txheej txheem tus lej xov tooj thiab nkag mus rau theem tom ntej ntawm tus lej xov tooj. Nws yog feem ntau siv rau hauv kev txhim kho lossis kev daws teeb meem tab sis tuaj yeem siv rau lwm tus raws li qhov xav tau.
cov txheej txheem tawm mus li cas?
Qhov feem ntau txiav txim siab tawm cov txheej txheem rau kev txiav lossis xaus cov txheej txheem ntawm kev sim yog:
- Hnub kawg raws li lossis pob nyiaj siv tas lawm.
- Kev ua tiav ntawm txhua qhov kev xeem.
- Xav tau thiab txaus kev pab them nqi ntawm cov kev xav tau thiab kev ua haujlwm hauv kev sim.
- Txhua yam uas raug txheeb xyuas tau raug kho thiab kaw.

Dab tsi yog cov xwm txheej rau txheej txheem haber?
Cua yog 78 feem pua nitrogen thiab yuav luag tag nrho cov seem yog oxygen. Thaum hydrogen hlawv hauv huab cua, cov pa oxygen ua ke nrog hydrogen - tawm hauv nitrogen tom qab. a qhov kub siab - txog 450 ° C a siab siab - txog 200 cua(200 npaug li qub siab) Vim li cas cov xwm txheej siv hauv Haber txheej txheem?
Cov txheej txheem twg yog txheej txheem gradational?
Gradational processes Weathering=breakdown of material in place Gradation=leveling of land degradation (erosion)=tshem tawm highs transport=txav ntawm cov khoom aggradation (deposition)=filling in lows Tectonic txheej txheem tsim los ntawm roughen lub ntiaj teb Gradational rog theem tawm highs thiab sau nyob rau hauv lows … Qhov twg ntawm cov txheej txheem hauv qab no yog cov txheej txheem gradational?
Nyob rau hauv tus txheej txheem desalination twg ntawm cov hauv qab no yog tshem tawm ntawm dej?
Desalination yog ib txheej txheem uas tshem tawm ntsev ntau dhau thiab lwm yam minerals tawm ntawm dej. Nyob rau hauv feem ntau cov txheej txheem desalination, pub dej yog kho thiab ob kwj dej yog tsim: kho cov dej tshiab uas muaj tsawg concentrations ntawm ntsev thiab minerals .
Puas yog txheej txheej txheej txheem siv los siv?
Kev txhim kho lub koom haum (OD) yog txheej txheej txheej txheem rau kev siv cov kev npaj hloov pauv kom ua rau tib neeg thiab cov koom haum ua tau zoo . Puas yog ib qho kev coj cwj pwm teb rau qhov tiag? Kev coj cwj pwm ntawm qhov kev xav ntawm kev xav yog qhov qhia tau tseeb ntawm kev xav.
Qhov txheej txheem twg yog qhov zoo tshaj plaws rau qhov muag tawv nqaij?
Yog tias koj muaj qhov txhab hauv qhov muag hnyav, sagging tawv nqaij, lossis hnyav puffiness hauv qab koj ob lub qhov muag, kev phais yuav yog txoj hauv kev zoo tshaj. Kev phais ntawm daim tawv muag qis, los yog blepharoplasty, tshem tawm cov rog ntau dhau thiab sagging ntawm daim tawv nqaij kom nruj thiab du daim tawv nqaij seem hauv qab ob lub qhov muag .
