Nws siv lub hauv paus ntsiab lus ntawm kev sib nrig sib inductance kev xav AC ncaj qha mus tam sim no , cais lub AC tam sim no , thiab tso zis ib txwm qhib los yog ib txwm kaw lub teeb liab hloov mus ncaj qha tswj ntau yam khoom siv automation, xws li flash, buzzer, relay, single-chip lossis lwm yam khoom siv fais fab.
Xav txog qhov no, qhov hloov pauv tam sim no ua haujlwm li cas?
Cov sensor ua haujlwm thaum lub tam sim no Tus neeg xyuas pib dhau los ntawm cov tub ntxhais sib nqus permeable uas ua rau cov neeg xyuas pib qhov chaw sib nqus. Qhov no tshwm sim vim yog lub magnetic teb uas tsim los ntawm ntws tam sim no . Inductive sensors yog siv rau AC tam sim no. Cov sensor muaj ib tug xov tooj-qhov txhab mob core thiab lub teeb liab txias.
Ib tug kuj yuav nug, dab tsi yog tam sim no sensing relay ua? Functionally, lawv paub tam sim no theem thiab muab cov teeb liab tso zis thaum muaj kev teev tseg tam sim no qib tau mus txog. Tam sim no - hnov relays yog siv rau: Signal high- tam sim no tej yam kev mob, xws li ib tug clogged grinder. Txheeb xyuas qis- tam sim no tej yam kev mob, xws li lub twj tso kua mis uas tau ntsib cov dej tsis zoo.
Tsis tas li ntawd, qhov hloov pauv tam sim no yog dab tsi?
Cov keyboards tam sim no yog siv thaum daim ntawv thov xav tau teeb liab thaum lub tam sim no ntws nyob rau hauv ib qho system tshaj los yog poob qis dua ib qho nqi. A hloov tam sim no yog siv los saib xyuas qhov no tam sim no qib. Ib txheej ntawm kev sib cuag yuav hloov lub xeev los ntawm ib qho kev kaw mus rau ib qho kev mob qhib lossis rov ua dua.
Koj txiav txim siab tam sim no hauv Circuit Court li cas?
Tam sim no sensing yog hais txog tiam ntawm lub teeb liab voltage uas muaj feem xyuam rau lub tam sim no hla hauv Circuit Court . Ib txoj hauv kev ntawm kev hnov tam sim no yog mus ntxig ib tug resistor nyob rau hauv txoj kev ntawm tam sim no ua kev xav . Tom qab ntawd peb tuaj yeem tso qhov kev xav ntawm qhov resistor nyob qhov twg hauv series nrog rau Circuit Court nws yuav yog load lossis hloov.

Dab tsi yog qhov kev hloov pauv hloov pauv?
Kev hloov pauv, hauv molecular biology, yog hais txog kev hloov pauv hauv deoxyribonucleic acid (DNA), qhov twg ib qho (ob lub nplhaib) purine hloov pauv rau (ib lub nplhaib) pyrimidine, los yog vice versa
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Dab tsi ua rau muaj qhov hloov pauv hloov pauv?
Point kev hloov. Point mutation, hloov nyob rau hauv ib tug noob nyob rau hauv uas ib tug hauv paus khub nyob rau hauv lub DNA ib theem zuj zus yog hloov. Kev hloov pauv ntawm cov ntsiab lus feem ntau yog tshwm sim los ntawm kev ua yuam kev thaum lub sij hawm DNA replication, txawm hais tias kev hloov pauv ntawm DNA, xws li los ntawm kev cuam tshuam rau X-rays lossis rau ultraviolet hluav taws xob, kuj tuaj yeem ua rau muaj kev hloov pauv
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
