X-/β-ray areal density gauge
Pamene cheza pa lifiyamu batire elekitirodi, cheza adzakhala odzipereka, kuonekera ndi kumwazikana ndi elekitirodi, kuchititsa attenuation ena a ray kwambiri kuseri kwa electrode opatsirana poyerekezera ndi zochitika cheza, ndi zomwe taneneratu attenuation chiŵerengero ali ndi zoipa exponential ubale ndi elekitirodi kulemera kapena pamwamba kachulukidwe.
Mfundo zoyezera
Chojambula cholondola cha "o"-mtundu:Kukhazikika kwanthawi yayitali, kuthamanga kwambiri kwa 24 m / min;.
Khadi yodzipangira yokha data yothamanga kwambiri:Kupeza pafupipafupi 200k Hz;
Mawonekedwe a makina a anthu:Ma chart olemera a data (ma chart opingasa & ofukula, tchati cholemera zenizeni, tchati choyambirira cha mawonekedwe amtundu wa data, ndi mndandanda wazinthu etc.); ogwiritsa amatha kufotokozera mawonekedwe azithunzi malinga ndi zomwe akufuna; ili ndi njira zoyankhulirana zodziwika bwino ndipo imatha kuzindikira kutsekeka kwa MES kotseka.
Mawonekedwe a chida choyezera kachulukidwe ka β-/X-ray
| Mtundu wa ray | Chida choyezera kachulukidwe ka B-ray - β-ray ndi mtengo wa elekitironi | X-ray pamwamba kachulukidwe kachulukidwe chida- X-ray ndi electromagnetic wave |
| Mayeso ogwira ntchito zinthu | Zinthu zoyeserera zogwiritsidwa ntchito: ma elekitirodi abwino komanso oyipa, zojambula zamkuwa ndi aluminiyamu | Zinthu zoyeserera: zabwino zama electrode cooper & zojambula za aluminiyamu, zokutira za ceramic zolekanitsa |
| Makhalidwe a Ray | Zachilengedwe, zokhazikika, zosavuta kugwiritsa ntchito | Moyo wamfupi kuposa β-ray |
| Kusiyana kwa kuzindikira | Zinthu za cathode zili ndi mphamvu yoyamwitsa yofanana ndi ya aluminiyamu; pomwe zinthu za anode zili ndi coefficient yoyamwa yofanana ndi yamkuwa. | Mayamwidwe a C-Cu a X-ray amasiyana kwambiri ndipo ma elekitirodi olakwika sangayesedwe. |
| Kuwongolera kwa radiation | Magwero achilengedwe a ray amayendetsedwa ndi boma. Chithandizo choteteza ma radiation chiyenera kuchitidwa pazida zonse, ndipo njira zopangira ma radiation ndizovuta. | Pafupifupi alibe ma radiation ndipo motero njira zovuta sizifunikira. |
Chitetezo cha Ma radiation
Mbadwo watsopano wa BetaRay density mita umathandizira kukonza chitetezo komanso kugwiritsa ntchito mosavuta. Pambuyo kulimbikitsa chitetezo cha ma radiation a gwero la gwero ndi bokosi la chipinda cha ionization ndikuchotsa chinsalu chotsogolera, chitseko chotsogolera ndi zinthu zina zazikulu, zimatsatirabe zomwe zili mu "GB18871-2002 - Basic Standards of Protection Against lonizing Radiation and Safety of Radiation Sources" yomwe nthawi zambiri imagwira ntchito kapena mlingo wofanana, mlingo wofanana pa 10 masentimita kuchokera kumalo aliwonse opezeka pazida sizikupitirira 1 1u5v / h. Panthawi imodzimodziyo, ingagwiritsenso ntchito ndondomeko yowunikira nthawi yeniyeni ndi makina odzilemba okha kuti azindikire malo oyezera popanda kukweza pakhomo la zipangizo.
Zosintha zaukadaulo
