Raws li ib tug neeg sawv cev downstream khoom ntawm refractory tungsten hlau, siab tshwj xeeb lub ntiajteb txawj nqus tungsten alloy muaj zoo heev shielding kev kawm ntxiv rau cov yam ntxwv ntawm non-radioactivity, siab ceev, siab zog, siab hardness thiab zoo tshuaj stability, thiab yog dav siv nyob rau hauv collimators, syringes. , shielding shields , shielding funnels , shielding kaus poom , shielding pam , flaw detectors , ntau nplooj gratings thiab lwm yam khoom siv tiv thaiv.
Cov cuab yeej tiv thaiv ntawm tungsten alloy txhais tau hais tias cov khoom tiv thaiv hluav taws xob xws li γ X-ray, X-ray thiab β Lub peev xwm ntawm txoj kab hluav taws xob nkag mus yog ze ze rau cov tshuaj muaj pes tsawg leeg, cov qauv tsim, cov khoom tuab, ib puag ncig ua haujlwm thiab lwm yam ntawm cov khoom siv. khoom.
Feem ntau, lub peev xwm tiv thaiv ntawm tungsten tooj liab alloy thiab tungsten npib tsib xee alloy yog qhov sib txawv me ntsis raws li cov khoom siv raw piv, microstructure thiab lwm yam. Thaum cov tshuaj muaj pes tsawg leeg zoo ib yam, nrog rau qhov nce ntawm tungsten cov ntsiab lus lossis txo cov hlau sib txuas (xws li npib tsib xee, hlau, tooj liab, thiab lwm yam) cov ntsiab lus, kev tiv thaiv kev ua haujlwm ntawm cov hlau zoo dua; Ntawm qhov tsis sib xws, kev tiv thaiv kev ua haujlwm ntawm cov hlau tsis zoo. Raws li tib yam li lwm yam kev mob, qhov ntau dua qhov tuab ntawm alloy, qhov zoo dua qhov kev tiv thaiv kev ua haujlwm. Tsis tas li ntawd, deformation, tawg, qhaub cij thiab lwm yam tsis xws luag yuav cuam tshuam rau kev tiv thaiv kev ua haujlwm ntawm tungsten alloys.
Kev tiv thaiv kev ua tau zoo ntawm tungsten alloy yog ntsuas los ntawm Monte Carlo txoj kev los xam X-ray shielding kev ua tau zoo ntawm cov hlau, los yog los ntawm txoj kev sim los ntsuas cov nyhuv shielding ntawm cov khoom siv alloy.
Monte Carlo txoj kev, tseem hu ua statistical simulation method thiab statistical test method, yog ib tug lej simulation txoj kev uas yuav siv sij hawm qhov tshwm sim tshwm sim raws li cov khoom tshawb fawb. Nws yog ib txoj hauv kev suav uas siv cov qauv kev soj ntsuam kom tau txais tus nqi txheeb cais los kwv yees tus yam ntxwv yam tsis paub. Cov kauj ruam yooj yim ntawm txoj kev no yog raws li hauv qab no: tsim cov qauv simulation raws li cov yam ntxwv ntawm kev sib ntaus sib tua; Txiav txim siab cov ntaub ntawv tseem ceeb; Siv cov txheej txheem uas tuaj yeem txhim kho qhov tseeb simulation thiab kev sib hloov ceev; Kwv yees tus naj npawb ntawm simulations; Sau cov kev pab cuam thiab khiav nws ntawm lub computer; Txheeb xyuas cov ntaub ntawv, thiab muab cov txiaj ntsig simulation ntawm qhov teeb meem thiab nws qhov raug kwv yees.
