Cov molecules hauv a ua kua siv lead ua tuaj yeem txav mus los ntawm nws tus kheej, zoo li hauv a ua kua , tab sis nyob twj ywm me ntsis, raws li nyob rau hauv ib tug siv lead ua (khoom). Cov no kua siv lead ua kua teb rau kev hloov hauv kub los ntawm hloov xim . Raws li cov kub nce, lawv xim hloov los ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav.
Tsis tas li ntawd, hom twg ntawm cov kua siv lead ua kua yog xim thiab hloov xim nrog qhov kub thiab txias?
Thermochromic Liquid Crystals
Tsis tas li ntawd, cov kua dej thermochromic ua haujlwm li cas? Thermochromic xim siv kua siv lead ua kua los yog leuco dye technology. Tom qab absorbing ib tug npaum li cas ntawm lub teeb los yog kub, lub crystallic los yog molecular qauv ntawm cov xim reversibly hloov nyob rau hauv xws li ib txoj kev uas nws absorbs thiab emits lub teeb ntawm ib tug txawv wavelength tshaj nyob rau hauv qis kub.
Ib yam li ntawd, cov kua siv lead ua kua ua haujlwm li ntsuas kub li cas?
Cov kua siv lead ua kua muaj cov khoom siv kho tshuab ntawm a ua kua , tab sis muaj cov khoom kho qhov muag ntawm ib leeg siv lead ua . Kub kev hloov pauv tuaj yeem cuam tshuam cov xim ntawm a siv lead ua kua , uas ua rau lawv muaj txiaj ntsig rau kub ntsuas. Kev daws teeb meem ntawm kua siv lead ua sensors yog nyob rau hauv 0.1 ° C ntau yam.
Dab tsi yog thermochromic pigment siv rau?
Thermochromic cov ntaub ntawv hloov xim ntawm qhov kub thiab txias. Feem ntau, lawv tau muab tso rau hauv tus cwj mem tshwj xeeb thiab luam tawm rau hauv cov yeeb yaj kiab yas los tsim cov ntsuas kub lossis ntsuas kub. Lub roj teeb kuaj sawb yog ib qho piv txwv zoo.

Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Tib neeg ua ntej hloov cov qoob loo li cas cov kws tshawb fawb siv niaj hnub no los hloov cov qoob loo?
Los ntawm cucumbers thiab carrots rau dawb nplej thiab nplej, peb tib neeg tau hloov cov noob ntawm yuav luag txhua yam zaub mov peb noj. Niaj hnub no cov kws tshawb fawb tuaj yeem tsim qhov kev hloov pauv sai sai los ntawm kev xaiv ib lub noob uas yuav ua rau muaj qhov xav tau thiab tso cov noob ncaj qha mus rau hauv chromosome ntawm lub cev
Vim li cas cov hlau lead siv hauv cov roj teeb cia?
