I-X-/β-ray ye-areal density gauge
Lapho umsebe usebenza ku-electrode yebhethri ye-lithium, umsebe uzomuncwa, ubonakale futhi usakazwe yi-electrode, okuholela ekuncipheni okuthile kokuqina kwe-ray ngemuva kwe-electrode edlulisiwe uma kuqhathaniswa nomsebe wesigameko, futhi isilinganiso sokuncishiswa esishiwo ngaphambili sinobudlelwano obungebuhle bokuchayeka nesisindo se-electrode noma ukuminyana kwendawo.
Izimiso zokulinganisa
Ukunemba "o"-uhlobo lokuskena lozimele:Ukuzinza okuhle isikhathi eside, isivinini esikhulu sokusebenza esingu-24 m/min;.
Ikhadi lokutholwa kwedatha elithuthukisiwe ngesivinini esiphezulu:Ukuvama kokutholwa okungu-200k Hz;
Isixhumi esibonakalayo somshini womuntu:Amashadi edatha anothile (amashadi ethrendi avundlile naqondile, ishadi lesisindo sesikhathi sangempela, ishadi ledatha yoqobo lweform, nohlu lwedatha njll.); abasebenzisi bangachaza ukwakheka kwesikrini ngokwezidingo zabo; ifakwe izimiso zokuxhumana ezijwayelekile futhi ingakwazi ukubona ukudotshwa kwe-MES okuvaliwe.
Izici zethuluzi lokulinganisa ukuminyana kwe-β-/X-ray
| Uhlobo lwe-ray | Ithuluzi lokulinganisa ukuminyana kwe-B-ray - i-β-ray iyisigqi se-electron | I-X-ray surface density meauringinstrument- I-X-ray igagasi lozibuthe kagesi |
| Ukuhlola okusebenzayo izinto | Izinto zokuhlola ezisebenzayo: ama-electrode amahle & angalungile, ama-foil ethusi ne-aluminium | Izinto zokuhlola ezisebenzayo: i-electrode cooper enhle & ne-aluminium foil, i-ceramic coating yesihlukanisi |
| Izici ze-ray | Imvelo, izinzile, kulula ukuyisebenzisa | Impilo emifushane kune-β-ray |
| Umehluko wokuthola | Impahla ye-cathode ine-coefficient yokumuncwa elingana neye-aluminium; kuyilapho impahla ye-anode ine-coefficient yokumuncwa elingana neyethusi. | I-C-Cu yokumunca i-coefficient ye-X-ray iyahlukahluka kakhulu futhi i-electrode engeyinhle ayinakulinganiswa. |
| Ukulawula imisebe | Imithombo ye-ray yemvelo ilawulwa umbuso. Ukwelashwa kokuvikela imisebe kufanele kwenziwe kumishini yonke, futhi izinqubo zemithombo ekhipha imisebe ziyinkimbinkimbi. | Cishe ayinayo imisebe futhi ngaleyo ndlela izinqubo eziyinkimbinkimbi azidingeki. |
Ukuvikelwa Kwemisebe
Isizukulwane esisha semitha ye-BetaRay density sinikeza ukuthuthukiswa kokuphepha kanye nokusetshenziswa kalula. Ngemva kokuthuthukisa umphumela wokuvikela wemisebe yebhokisi lomthombo kanye nebhokisi legumbi le-ionization kanye nokuvala ikhethini eliholayo, umnyango oholayo nezinye izakhiwo ezinkulu, lisahambisana nezinhlinzeko ze-"GB18871-2002 - Basic Standards of Protection Against lonizing Radiation and Safety of Radiation Sources" ngaphansi kwezimo ezivamile zokusebenza noma umthamo olinganayo, isilinganiso esilinganayo ku-10 cm kusuka kunoma iyiphi indawo efinyelelekayo yemishini ayidluli i-1 1u5v / h.Ngaso leso sikhathi, ingasebenzisa futhi uhlelo lokuqapha lwesikhathi sangempela kanye nesistimu yokumaka okuzenzakalelayo ukumaka indawo yokulinganisa ngaphandle kokuphakamisa iphaneli yomnyango wemishini.
