Kushandiswa kwechigadzirwa
Kushandiswa kwemaindasitiri
Selenium ine ese mafoto emoto uye logsensitive zvivakwa. Playelectric performance inogona kushandura mwenje zvakananga kuita magetsi, uye kuita kwe photoensitive kunogona kuderedza kuramba kana uchiwedzera mwenje. Iyo fotolectric uye photosensitive zvivakwa zveSelenium inogona kushandiswa mukugadzirwa kwemifananidzo uye kufumurwa mita yemakamera uye maseru ezuva. Selenium inogona kushandura kuchinjika zvazvino kuti zvive zvazvino zvakananga, saka inozoshandiswa zvakanyanya mukugadzirwa kwezvigadzirisi. Selenium Elemental is a P-Type Semiconductor iyo inogona kushandiswa mumatunhu uye zvakasimba-nyika zvikamu. MuPhosikoping, Selenium inogona kushandiswa kutevedzera zvinyorwa uye mavara (toner cartridges). Mugirazi girazi, Selenium inogona kushandiswa kuburitsa yakagadziridzwa girazi, ruby ruvara rwegirazi uye enamel.

Inokwirisa impunity
STES STALE SELERIUUM inogona kujekesa ma radicals yemahara mumuviri, itsimudzire mumuviri, unogona kunyatsoita kuti kugadzirwa kweLIPID Peroxide, kudzivisa mango eropa, bvisa cholesterol, uye kuwedzera vanhu vemo basa.
Dzivirira chirwere cheshuga
Selenium chinhu chinoshanda cheGlutatione peroxidase, chinogona kudzivirira kuparadzwa kweLELET BATA SELLE, kusimudzira shuga yeropa uye shuga yeropa, uye kuvandudza zviratidzo zvevarwere veshuga.
Dzivirira Catract
Iyo retina iri panjodzi yekukuvara nekuda kwekuratidzwa kwakawanda kune makombiyuta redhiation, Selenium inogona kuchengetedza retina, simbisa iyo yekupedzisa muviri, kugadzirisa maziso, uye kudzivirira zvakabatana.
