Cov khoom siv tau yooj yim yog siv los txuas rau lub cev muaj zog lossis lwm yam khoom siv uas kev sib cais los ntawm kev vibration yog qhov muaj txiaj ntsig, lossis qhov twg ntau cov fittings xav tau los siv cov kev sib txuas nruj. Cov lej hluav taws xob tuaj yeem txwv qhov ntev ntawm kev khiav ntawm qee hom kev hloov pauv tau yooj yim.
Yuav tsum muaj qhov hloov pauv qhov twg?
Siv tau yooj yim metallic conduits lossis FMCs feem ntau yog siv hauv tsev lag luam. Cov conduit no tshwj xeeb yog siv rau hauv cov cheeb tsam uas nws tsis tuaj yeem siv cov kav dej nruj. Nws tuaj yeem muab lub zog txaus thiab kev tiv thaiv nrog cov txiaj ntsig ntxiv ntawm kev yoog raws.
Cov kav dej hloov pauv tau siv rau dab tsi?
Cov khoom siv tau yooj yim siv txhawm rau txuas rau lub cev muaj zog lossis lwm yam khoom siv uas kev sib cais los ntawm kev vibration yog qhov muaj txiaj ntsig, lossis qhov twg ntau dhau ntawm fittings yuav tsum tau siv cov kev sib txuas nruj. Cov lej hluav taws xob tuaj yeem txwv qhov ntev ntawm kev khiav ntawm qee hom kev hloov pauv tau yooj yim.
Dab tsi yog qhov siv ntau tshaj ntawm cov kav dej hloov pauv tau?
Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob tuaj yeem siv los ua xaim, cable, tsis siv neeg ntsuas teeb liab xaim thiab cable tiv thaiv yeeb nkab. Nws muaj softness zoo, corrosion kuj, siab kub kuj, puas kuj thiab tensile khoom.
Yuav ua li cas yog qhov hloov pauv tau?
Cov kav hlau txuas tau yooj yim (FMC) muajkev siv cov kauv uas ua rau nws ua rau nab los ntawm cov phab ntsa thiab lwm cov qauv. … Liquidtight saj zawg zog hlau conduit (LFMC) yog ibhom tshwj xeeb ntawm FMC uas muaj cov txheej txheem yas. Thaum siv cov fittings kaw, nws dhau los ua dej.

Puas yog qhov hloov pauv tau thaum lub sijhawm muaj kev hloov pauv?
Kev hloov pauv hloov pauv hloov pauv kev lag luamthiab yog li hloov lub ntiaj teb. Txhua qhov kev tsim kho tshiab uas tawm los ntawm kev hloov pauv kev lag luam tau txais txiaj ntsig los ntawm kev sib hloov pauv, lub tshuab nqus tsev, tshuab xaws, xov tooj, thiab ntau dua.
Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
