Dab tsi yog cov roj ntsuas kub, thiab nws lub ntsiab siv yog dab tsi?
Tso lus
Cov tshuab hluav taws xob kub yog ib qho cuab yeej siv los ua kom sov thiab tswj qhov ntsuas kub. Nws tsuas yog muaj lub rhaub thiab dej da dej uas muaj cov kua.
Cov tshuab hluav taws xob kub kub ua kom sov cov kua rau qhov teeb kub los ntawm kev tso pa taws rau cov kua los ntawm kev kub.
Cov ntawv thov tseem ceeb ntawm cov tswj hluav taws kub suav nrog cov hauv qab no:
1. Lub Chaw Haujlwm Saib Xyuas Haujlwm thiab Kev Tshawb Fawb: Cov tswj cov roj kub tau siv dav siv hauv kev tshawb fawb thiab chaw soj ntsuam. Lawv tau siv los tswj qhov kub ntawm cov tshuaj lom neeg cov tshuaj tiv thaiv, pab cov kws tshawb nrhiav ua kev sim ntawm qhov kub. Hauv cov liaj teb xws li analytical chemistry, biochemistry, thiab cov hluav taws xob organic, cov ntsuas kub thiab txias thiab ruaj khov ntawm kev sim.
2. Kev lag luam cua sov: hauv kev lag luam khoom siv, cov tswj cov roj thiab cov xim kub, xws li cov xim, xws li cov xim, ua cov nplaum. Los ntawm kev tswj qhov kub thiab txias, cov kua muaj peev xwm ua kom tau kom ncav cuag cov neeg txawv txav viscosity thiab flowability nyob rau hauv cov txheej txheem tshwj xeeb.
3. Kev Noj Qab Haus Huv: Hauv kev tswj xyuas kev kho mob, reagents cov khoom siv kub thiab reagents hlab, petri lauj kaub tais diav, thiab koob hmoov. Los ntawm kev tswj qhov kub thiab txias, ib puag ncig uas haum tau muab rau kom ntseeg tau tias qhov ruaj khov thiab kev ntseeg tau ntawm cov khoom siv kho mob thiab reagents.
4. Kev ua zaub mov noj: hauv kev tsim khoom noj khoom haus, cov roj kub siv tau dav rau cua sov thiab tswj qhov kub ntawm cov zaub mov ua kua. Piv txwv li, hauv cov chaw tsim khoom chocolate chocolate, roj kub tswj tau siv los ua kom sov thiab tswj cov kua chocolate los khaws nws lub ntsej muag thiab kev ua tau zoo thaum tsim thiab ntim khoom.
Kev siv cov roj siv hluav taws xob kub tuaj yeem txhim kho cov kev txhawb nqa ntawm cov txheej txheem tsim khoom thiab muab cov cuab yeej tseem ceeb hauv kev tshawb fawb thiab kev tsim kho tshiab.
