Ib qho taw qhia olfactory ua haujlwm ntawm lub hauv paus ntsiab lus tias thaum muaj kua qaub lossis lub hauv paus ntxiv rau nws, ces cov ntxhiab tsw txawv tuaj yeem kuaj pom hauv cov hauv paus whereastsw tsw zoo ib yam hauv cov kua qaub. Qee yam tshuaj uas hloov nws cov ntxhiab hauv Acidic lossis nruab nrab nruab nrab. … Cov cim taw qhia kev hloov pauv ua ntej kev lag luam raws li kev hloov pauv tag nrho.
Koj yuav ntsuas cov kua qaub thiab lub hauv paus siv qhov ntsuas olfactory piav qhia nws li cas?
Teb: cov ntsuas olfactory yog siv los txheeb xyuas seb cov khoom puas yog hauv paus lossis acid. Raws li cov ntsuas no qhia qhov hloov pauv tseem ceeb hauv tsw xws li dos, vanilla, clove. Dos: thaum dos muab tshuaj txhuam rau alkaline nruab nrab / tshuaj nws poob nws tsis hnov tsw thaum nyob rau hauv acidic nruab nrab nws khaws nws tsw.
ntsuas ntsuas qhov txawv ntawm cov kua qaub thiab cov hauv paus li cas?
Cov ntsuas yog cov khoom uas pab peb paub qhov txawv ntawm cov kua qaub thiab cov hauv paus. Feem ntau, qhov no tau ua tiav los ntawm kev hloov ntawm cov xim sib haum rau kev hloov pauv hauv pH ntawm cov khoom. … Cov ntsuas tau zoo dhau los hloov xim xim ntawm tus nqi pH tshwj xeeb, uas pab peb txiav txim siab pH ntawm cov tshuaj tsis paub.
Dab tsi yog qhov ntsuas ntawm olfactory?
Raws li peb paub tias qee yam khoom uas nws hnov los yog tsw hloov hauv cov kua qaub lossis cov ntsiab lus tseem ceeb hu ua olfactory indicators. Peb yuav tsum nco ntsoov tias dos thiab vanilla extracts yog qhov ntsuas olfactory. Vanillaessence is an olfactory indicator.
Dab tsi yog qhov kev hloov pauv qhov ntsuas qhov ntsuas pom tau pom tau?
Olfactory Indicators: Cov khoom uas hloov lawv cov ntxhiab thaum tov nrog kua qaub los yog hauv pausyog lub npe hu ua olfactory indicators. Piv txwv li dos, vanilla, clove, thiab lwm yam. Olfactory ntsuas yog siv los xyuas kom meej kev koom tes ntawm cov tub ntxhais kawm tsis pom kev hauv chav kuaj.

Yuav ua li cas ntsuas cov kua qaub kom nce lub zog?
Bond Strength and Acids Lub zog ntawm cov kua qaub feem ntau nyob ntawm qhov loj ntawm 'A' atom: qhov me dua 'A' atom, qhov muaj zog H-A daim ntawv cog lus. Thaum nkag mus rau hauv kab hauv Lub Sijhawm Teem Sijhawm (saib daim duab hauv qab), cov atoms tau loj dua yog li lub zog ntawm daim ntawv cog lus tsis muaj zog, uas txhais tau hais tias cov kua qaub muaj zog dua.
Puas yog acridine yog cov kua qaub lossis lub hauv paus?
Nws yog ib qho qauv molecule uas muaj feem cuam tshuam nrog anthracene nrog ib qho ntawm cov pawg CH hauv nruab nrab hloov los ntawm nitrogen. Zoo li cov molecules pyridine thiab quinoline, acridine yog me ntsis yooj yim. Nws yog ib qho yuav luag tsis muaj xim, uas crystallizes hauv koob.
Ntsuas ntsuas ntsuas ntsuas dab tsi?
Speedometer, ntsuas uas qhia tias kev ceev ntawm lub tsheb, feem ntau ua ke nrog cov cuab yeej hu ua odometer uas teev qhov kev ncua deb. Lub ntsuas ntsuas ntsuas ntsuas lub cev yog dab tsi? Lub ntsuas nrawm ntawm lub tsheb nthuav tawm cov ntaub ntawv hais txog qhov nrawm nrawm ntawm koj lub tsheb.
