Kev kuaj xyuas zaub mov yog ib txoj kev siv los xyuas tias a zaub mov muaj kev nyab xeeb thiab nws tsis muaj cov kab mob tsis zoo, lossis nws tsuas muaj cov tshuaj ntxiv tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, lossis kom paub cov qib ntawm cov as-ham tam sim no.
Ua raws li qhov no, qhov tseem ceeb ntawm kev ua piv txwv yog dab tsi?
Qauv yog tseem ceeb vim nws ua tsis tau (saib, xam phaj, soj ntsuam, thiab lwm yam) tag nrho cov pejxeem. Thaum tshawb xyuas, txawm li cas los xij, nws yog ib qho tseem ceeb kom ntseeg tau cov neeg hauv koj qauv xav txog cov pejxeem los yog lwm yam koj yuav tau txais kev dag ntxias.
Kuj Paub, koj coj cov qauv zaub mov li cas? Txhawm rau kom ntseeg tau tias kev ncaj ncees ntawm cov qauv zaub mov raug coj mus, muaj ntau yam uas yuav tsum tau ua.
- Txheeb xyuas qhov kev tsom xam kom raug.
- Ntxuav cov khoom siv kuaj.
- Kev tu tus kheej zoo.
- Yog tus qauv loj.
- Tsim nyog cia thiab thauj tej yam kev mob.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov tseem ceeb ntawm kev ua piv txwv hauv analytical chemistry?
Qauv yog qhov tseem ceeb rau txhua qhov chaw uas analytical chemistry muaj lub luag haujlwm ua si. Ambient kev kuaj ntawm huab cua yog siv los muab kev tsom xam cov ntaub ntawv ntawm lub caij nyoog los yog lwm yam tiam sis uas tuaj yeem cuam tshuam nrog cov txheej txheem ntuj tsim los yog kev sib raug zoo.
Cov qauv dawb puas nce kev muag khoom?
Tab sis tsis txhob cia qhov dissuade koj, vim kuaj dawb tuaj yeem tsim ntau ntau muag rau koj dhau sijhawm. Qee zaum, kuaj dawb tuaj yeem txhawb nqa muag los ntawm ntau npaum li 2,000%. Koj siv tau kuaj dawb rau: Qhia koj cov khoom rau cov neeg tuaj saib tshiab uas tsis paub txog koj lub hom phiaj.

Dab tsi yog qhov tseem ceeb ntawm kev siv cov zaub mov?
Kev siv cov zaub mov. Cov ntxhia zoo li tooj liab yog siv hauv cov khoom siv hluav taws xob vim nws yog cov khoom siv hluav taws xob zoo. Av nplaum yog siv los ua cov cement thiab lwm yam uas pab tsim txoj kev. Fiberglass, tshuaj ntxuav yog tsim los ntawm borax
Vim li cas kev lag luam tshuaj suav hais tias yog kev lag luam yooj yim?
Kev lag luam tshuaj siv cov khoom siv raw los tsim cov khoom lag luam qhia cov kua qaub, hauv paus, alkali thiab ntsev. Cov khoom siv feem ntau yog siv rau hauv kev tsim khoom ntawm lwm cov khoom lag luam xws li iav, chiv, roj hmab, tawv, ntawv thiab textiles. Yog li, peb tuaj yeem hais tias kev lag luam tshuaj lom neeg yog kev lag luam yooj yim
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas kev ntsuas thiab ntsuas qhov tseem ceeb hauv kev tshawb fawb txog kev lag luam?
Cov nplai tau siv ntau zaus hauv kev tshawb fawb kev lag luam vim tias lawv pab hloov cov ntaub ntawv zoo (xav, kev xav, kev xav) rau hauv cov ntaub ntawv ntau, cov lej uas tuaj yeem txheeb xyuas tau. Koj tsim ib qho kev ntsuas los ntawm kev muab cov khoom (yuav ua tau piav qhia) rau tus lej
Vim li cas thiaj muaj kev lag luam thiab kev ua lag luam?
Ua thiab lagging strands coli, DNA polymerase uas tswj feem ntau ntawm cov synthesis yog DNA polymerase III. Cov strand no yog ua tsis tu ncua, vim hais tias DNA polymerase yog txav mus rau tib qho kev taw qhia raws li cov diav rawg replication. Qhov no tsis tu ncua synthesized strand yog hu ua tus thawj strand
