Ib yam Cov ntaub ntawv nug chav nyob hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, video cov cuab yeej tsom xam thiab cov cuab yeej tshwj xeeb suav nrog cov cuab yeej ntsuas hluav taws xob electrostatic (EDD) thiab cov khoom siv los ua chemistry analytical.
Kuj paub tias, cov neeg soj ntsuam saib dab tsi thaum kuaj xyuas cov ntawv sau?
Aspects Analyzed Forensic document cov kws tshuaj saib tsis tsuas yog ntawm kev sau ntawv tes tab sis kuj yog daim ntawv, number case thiab sau ntawv siv tau. Lawv saib rau cov pov thawj tias ib lossis ntau lo lus tau ntxiv lossis hloov kho tom qab sau tus thawj.
Dab tsi yog suav tias yog ib qho kev ntsuam xyuas rau cov ntaub ntawv nug? Ntau QD kev xeem koom nrog kev sib piv ntawm cov nug cov ntaub ntawv , los yog cov khoom ntawm cov ntaub ntawv , mus rau cov txheej txheem paub. Feem ntau feem ntau hom ntawm kev tshuaj xyuas suav nrog kev sau ntawv uas tus kws tshuaj xyuas sim daws cov kev txhawj xeeb txog kev muaj peev xwm sau ntawv.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi cov cuab yeej siv hauv kev txheeb xyuas cov ntaub ntawv?
Kev ntsuas yooj yim cuab yeej suav nrog metric rulers, calipers rau kev ntsuas zoo thiab ntau yam iav sib dhos daim hlau xws li ib qho piv txwv hauv qab no uas tso cai rau kev sib piv thiab ntsuas lub kaum ntse ntse, qhov siab, qhov dav thiab qhov sib txawv ntawm kev sau ntawv tes thiab ntaus ntawv.
Cov txheej txheem twg tuaj yeem nthuav qhia kev sau ntawv?
Lub chaw soj nstuam zoo niaj hnub siv cov khoom siv hluav taws xob electrostatic kom rov qab sau cov ntawv sau. Cov cuab yeej raug xa mus ua ib qho ESDA , luv luv rau Electro-static Detection Apparatus. Los ntawm kev ua haujlwm ESDA , indented sau ntawv tej zaum yuav rov qab tau peb, plaub, los yog ntau nplooj ntawv hauv qab tus thawj sau ntawv.

Cov cuab yeej dab tsi uas tus kws tshawb fawb marine siv?
Qee cov cuab yeej siv los kawm txog biology ntawm cov kab mob hauv hiav txwv muaj xws li cov cuab yeej siv xws li plankton nets thiab trawls, cov khoom siv hauv qab dej xws li lub koob yees duab yees duab, tsheb khiav deb, hydrophones thiab sonar, thiab kev taug qab txoj hauv kev xws li satellite cim npe thiab kev tshawb fawb yees duab
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
Peb hom cheeb tsam yog dab tsi uas cov kws tshawb fawb txheeb xyuas?
Nyob rau hauv geography, peb hom cheeb tsam yog: formal, functional thiab vernacular. Cov cheeb tsam yog cov khoom siv hluav taws xob uas tso cai rau cov kws tshawb fawb los sib piv cov cheeb tsam hauv ntiaj teb kom ntxaws. Cov cheeb tsam raug cai muaj xws li thaj chaw thaj chaw, thaj chaw kab lis kev cai, tsoomfwv cheeb tsam thiab cheeb tsam kev lag luam
