I-X-/β-reyi ye-areal density gauge
Xa i-ray isebenza kwi-electrode yebhetri ye-lithium, i-ray iya kuxutywa, ibonakaliswe kwaye isasazwe yi-electrode, okukhokelela ekunciphiseni okuthile kwe-ray intensity emva kwe-electrode ethunyelwayo xa kuthelekiswa ne-ray yesiganeko, kwaye umlinganiselo okhankanywe ngaphambili unobudlelwane obubi be-exponential kunye nobunzima be-electrode okanye ubuninzi bomhlaba.
Imigaqo yokulinganisa
Ukuchaneka "o"-uhlobo lwesakhelo sokuskena:Ukuzinza okuhle kwexesha elide, isantya esiphezulu sokusebenza kwe-24 m / min;.
Ukuziphuhlisa ngokwakho ikhadi lokufunyanwa kwedatha ngesantya esiphezulu:Ukufumana rhoqo 200k Hz;
Ujongano lomatshini woluntu:Iitshathi zedatha ezityebileyo (iitshathi ezithe tyaba nezithe nkqo, itshathi yobunzima bexesha lokwenyani, itshathi yedatha yoqobo, kunye noluhlu lwedatha njl.); abasebenzisi banokuchaza uyilo lwesikrini ngokweemfuno zabo; ifakelwe kwiiprothokholi zonxibelelwano ezingundoqo kwaye inokuqonda i-docking ye-MES evaliweyo.
Iimpawu ze-β-/X-reyi isixhobo sokulinganisa ubuninzi bomphezulu
| Uhlobo lweRay | Isixhobo sokulinganisa uxinano lomphezulu we-B-reyi - β-reyi ngumqa we-electron | Isixhobo sokulinganisa uxinaniso lweX-reyi- X-reyi liza lombane lombane |
| Uvavanyo olusebenzayo izinto | Izinto zokuvavanya ezisebenzayo: ii-electrode ezilungileyo kunye nezingalunganga, iifoyile zobhedu kunye ne-aluminium | Izinto zokuvavanya ezisebenzayo: i-electrode esebenzayo kunye neefoyile ze-aluminium, i-ceramic coating ye-separator |
| Iimpawu zeRay | Indalo, izinzile, kulula ukuyisebenzisa | Ubomi obufutshane kuno-β-reyi |
| Umahluko wokufunyanwa | Izinto zeCathode zine-coefficient yokufunxa elingana ne-aluminiyam; ngelixa izinto ze-anode zine-coefficient yokufunxa elingana naleyo yobhedu. | I-C-Cu ye-absorption coefficient ye-X-ray iyahluka kakhulu kwaye i-electrode engalunganga ayinakulinganiswa. |
| Ulawulo lwemitha | Imithombo yemitha yendalo ilawulwa ngurhulumente. Unyango lokukhusela i-radiation kufuneka lwenziwe kwisixhobo ngokubanzi, kwaye iinkqubo zemithombo ye-radioactive zinzima. | Phantse akukho mitha kwaye ngoko ke iinkqubo ezinzima azifuneki. |
uKhuseleko lwemitha
Isizukulwana esitsha semitha yoxinano lweBetaRay sibonelela ngokuphuculwa kokhuseleko kunye nokulula ukusetyenziswa. Emva kokuphucula impembelelo yokukhusela ukusasazeka kwemitha yebhokisi yemithombo kunye nebhokisi yegumbi le-ionization kunye nokuphelisa umkhusane okhokelayo, umnyango okhokelayo kunye nezinye izakhiwo ezinkulu, isathobela imimiselo ye "GB18871-2002 - iMigangatho eyiSiseko yoKhuseleko oluchasene neRadiation kunye noKhuseleko lweMithombo yeRadiation" apho phantsi kweemeko eziqhelekileyo zokusebenza okanye idosi elinganayo okanye idosi yesiqhelo yokusebenza, izinga elilinganayo kwi-10 cm ukusuka kuyo nayiphi na indawo efikelelekayo yesixhobo ayidluli i-1 1u5v / h. Ngelo xesha, inokuphinda isebenzise inkqubo yokubeka iliso yexesha langempela kunye nenkqubo yokumakisha ngokuzenzekelayo ukuphawula indawo yokulinganisa ngaphandle kokuphakamisa ipaneli yomnyango wesixhobo.
