In thermoluminescence dating, cov ntxiab mus sij hawm ntev no yog siv los txiav txim lub hnub nyoog ntawm cov ntaub ntawv: Thaum cov khoom siv irradiated crystalline rov qab los yog raug rau lub teeb muaj zog, cov khoom siv hluav taws xob yog muab lub zog txaus kom dim. … Yog li ntawd, thaum lub sij hawm ntawd lub teeb liab thermoluminescence yog xoom.
Puas yog thermoluminescence kev sib raug zoo?
Siv oxygen thiab lithium ions los ntawm Tandem accelerator ntawm National Institute of Nuclear Physics (INFN) hauv Florence, cov kws tshawb fawb pom tias lawv qhov ntsuas tau raug nyob rau hauv 1%, txawm tias Kev hloov pauv loj hauv cov kab hluav taws xob irradiation.
Yuav rov qab mus deb npaum li cas thermoluminescence yos mus?
Nws yog ib txoj kev sib tham uas nrov heev hauv archaeology vim tsis yog nws tuaj yeem hnub lub lauj kaub tais diav, hom khoom peb pom tshaj plaws thaum khawb, tab sis nws tseem tuaj yeem rov qab hnub ntxiv dua 50,000 xyootsis zoo li xov tooj cua sib tham. Qhov ntawd, thiab nws pheej yig dua piv rau lwm txoj kev sib tham.
Puas yog thermoluminescence ib txoj kev sib tham tiag?
Qhov no yog hom kev qhia nkaus xwb uas tuaj yeem pab qhia meej lub hnub nyoog tiag tiag ntawm cov khoom. Absolute txoj kev sib tham feem ntau suav nrog xov tooj cua sib tham, dendrochronology thiab thermoluminescence.
Leej twg nrhiav tau thermoluminescence yos txoj kev?
Lub sijhawm xyoo 1970 thiab 1980s kws tshawb fawb ntawm Simon Frasier University, Canada, tsim qauvthermoluminescence dating txheej txheem siv rau hnub sediments. Xyoo 1985, lawv kuj tau tsim kho qhov muag pom kev luminescence dating, uas siv lub teeb laser, rau hnub sediments. Luminescence ua haujlwm li cas?
