Kev txhais ntawm nonionic detergent .: ib yam ntawm cov chav kawm ntawm hluavtaws tshuaj ntxuav tes (raws li cov hlua ntev ether derivatives lossis esters ntawm cawv lossis phenols) uas tsis yog anionic lossis cationic tab sis tsim hluav taws xob nruab nrab colloidal hais hauv kev daws.
Ib yam li ntawd, cov tshuaj ntxuav tes uas tsis yog ionic muab piv txwv li cas?
Tsis yog - ionic detergents Lawv yog cov yam ntxwv ntawm lawv uncharged, hydrophilic headgroups. Hom tsis yog - ionic detergents yog raws li polyoxyethylene los yog glycoside. Feem ntau piv txwv ntawm yav dhau los suav nrog Tween, Triton, thiab Brij series.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm ionic thiab nonionic yog dab tsi? Cov Qhov sib txawv ntawm ionic thiab nonionic surfactants yog cov ionic surfactants muaj cov ntsiab lus cations los yog anions tam sim no nyob rau hauv nws cov formulation whereas lub nonionic surfactants tsis muaj cations los yog anions tam sim no nyob rau hauv nws formulation.
Ib yam li ib tug yuav nug, ua li cas cov tshuaj tsis muaj ionic ua haujlwm?
Tsis yog - ionic detergents yog tsawg hnyav dua ionic detergents , muaj peev xwm txwv rau rhuav tshem cov protein-protein kev sib tshuam. Cov no detergents yog muaj txiaj ntsig zoo ntawm kev sib cais cov kab mob ua haujlwm hauv daim nyias nyias, lossis rhuav tshem cov lipid-lipid thiab lipid-protein kev sib cuam tshuam.
Dab tsi yog nonionic surfactants?
Nonionic surfactants yog cov saw hlau ntev ntev uas tsis sib cais, piv txwv li, phenol 30-mol ethylene oxide: C6H5-O-(CH2CH2O) 30H uas paub hauv kev lag luam drilling li DMS (Burdyn thiab Wiener 1957).

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov zeros ntawm kev ua haujlwm Dab tsi yog qhov sib txawv?
Tus naj npawb ntawm lub sij hawm ib qho tseem ceeb tshwm sim nyob rau hauv daim ntawv factored ntawm qhov sib npaug ntawm ib tug polynomial yog hu ua multiplicity. Qhov xoom cuam tshuam nrog qhov xwm txheej no, x = 2, muaj ntau qhov sib npaug 2 vim tias qhov xwm txheej (x− 2) tshwm sim ob zaug. X-intercept x=− 1 yog qhov rov qab daws ntawm qhov xwm txheej (x + 1) 3 = 0 (x + 1) 3 = 0
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov index fossil Dab tsi yog ob qhov yuav tsum tau ua ib qho index fossil?
Cov pob txha muaj txiaj ntsig zoo yuav tsum yog qhov sib txawv lossis pom tau yooj yim, muaj ntau, thiab muaj qhov dav ntawm thaj chaw faib khoom thiab muaj ntau yam luv luv los ntawm lub sijhawm. Index fossils yog lub hauv paus rau kev txhais cov ciam teb nyob rau hauv lub sij hawm geology thiab rau kev sib raug zoo ntawm strata
