Cov txheej txheem pathogenic ntawm tus kab mob (lossis tus mob) yog teeb tsa los ntawm cov laj thawj hauv qab, uas yog tswj tau yuav cia tus kab mob tiv thaiv. Feem ntau, qhov ua rau muaj peev xwm raug txheeb xyuas los ntawm kev soj ntsuam kab mob sib kis ua ntej qhov kev sib txuas ntawm cov kab mob tuaj yeem cuam tshuam ntawm qhov ua rau thiab tus kab mob.
Dab tsi yog cov txheej txheem pathogenic ntawm cov kab mob?
Cov kab mob kab mob siv cov txheej txheem tswj hwm, xws li lwm yam sigma thiab ob lub teeb liab hloov pauv cov kab ke, txhawm rau tswj kev qhia ntawm lawv cov noob kab mob phem hauv kev teb rau ib puag ncig cov xwm txheej ntsib thaum kis kab mob ntawm tib neeg tus tswv, suav nrog kev hloov pauv hauv qhov kub, pH, osmotic …
piv txwv ntawm kab mob yog dab tsi?
Piv txwv ntawm cov kab mob kab mob yog kab mob kis, kab mob, prions, fungi, viroids, thiab kab mob ua rau kab mob. Lawv lub peev xwm tsim tau kab mob cuam tshuam nrog lawv cov yam ntxwv uas lawv tau txais thaum lawv siv zog ua kom muaj sia nyob hauv lawv tus tswv.
Dab tsi yog microbial mechanism pathogenicity?
Microbes nthuav qhia lawv cov kab mob los ntawm txhais tau tias ntawm lawv cov kab mob, ib lo lus uas hais txog qib ntawm pathogenicity ntawm microbe. Li no, qhov kev txiav txim siab ntawm kev ua phem ntawm tus kab mob yog ib qho ntawm nws cov caj ces lossis biochemical lossis cov yam ntxwv uas ua rau nws tsim cov kab mob hauv tus tswv.
YYuav ua li cas yog tus kab mob?
Ib tus kab mob txhais tau tias yog kab mob ua rau nws tus tswv tsev, nrog rau qhov mob hnyav ntawm tus kab mob hu ua virulence. Cov kab mob muaj ntau hom kab mob sib txawv thiab suav nrog cov kab mob thiab cov kab mob xws li unicellular thiab multicellular eukaryotes.

Vim li cas cov ntawv xov xwm pabcuam raug muab tso rau hauv cov txheej txheem tshuaj xyuas?
Lawv ceeb toom rau cov tswv dav hlau thiab cov tswv ntawm cov xwm txheej tsis zoo uas xav tau kev tshuaj xyuas tshwj xeeb, hloov pauv, lossis kho dua. Daim Ntawv Qhia Kev Pabcuam (S.B.) yog ib daim ntawv ceeb toom rau tus neeg tsav dav hlau los ntawm lub chaw tsim khoom qhia nws txog kev txhim kho cov khoom .
Nyob rau hauv cov txheej txheem nitriding cov nh3 roj tau qhia ntawm?
diffused rau hauv steel2). Txij li thaum ob qho kev cuam tshuam saum toj no tshwm sim ib txhij hauv furnace, NH3 tau qhia tas li nyob rau hauv lub qhov cub kom cov cua nitriding uas muaj NH3 tswj kom muab nitrogen rau cov hlau . Cov roj twg siv rau hauv cov txheej txheem nitriding?
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?
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.
