Cov txheej txheem:
- Vim li cas peb tsis tuaj yeem saib xyuas vuam: peb niam peb txiv tau dag peb?
- Cov phom sij ntawm kev vuam mus rau qhov pom: delusion lossis qhov tseeb
Vim li cas peb tsis tuaj yeem saib xyuas vuam: peb niam peb txiv tau dag peb?
Kev haujlwm ntawm tus kws txuas txuas rau lub ntsej muag ib txwm nyiam mloog - tus yam ntxwv zoo li lub suab tau hnov, qhov zoo ntawm lub teeb pom kev zoo thiab lub ntsej muag zoo nyob hauv txhua qhov kev qhia. Nws tsis yog qhov xav tsis thoob uas koj xav saib txoj haujlwm no, tab sis txhua tus paub txij thaum yau los uas koj tsis tuaj yeem saib hlau, nws muaj kev phom sij rau lub qhov muag. Cia peb xam seb qhov no yog tiag tiag thiab yog li cas ib tus neeg raug hem los ntawm kev saib xyuas kev ua haujlwm tsis muaj kev tiv thaiv.
Cov phom sij ntawm kev vuam mus rau qhov pom: delusion lossis qhov tseeb
Tsis muaj leej twg yuav txwv tsis pub saib cov haujlwm ntawm vuam, tab sis tsis muaj kev tiv thaiv tshwj xeeb rau lub qhov muag, qhov no tuaj yeem tig mus rau qhov kev rau txim tu siab. Txhawm rau kom nkag siab lub hauv paus ntawm kev tsim txom, koj yuav tsum xam qhov tseeb dab tsi ua rau nws mob.
Thaum lub sijhawm ua haujlwm ntawm lub tshuab vuam, ib qho arc tsim - lub tshuab txuas hluav taws xob tsis tu ncua uas tau tsim los ntawm thaj chaw electrode thiab thaj chaw ntawm lub chaw txuas. Raws li qhov kev txiav txim siab ntawm qhov kub thiab txias, qhov poob ntawm molten hlau zoo li, uas tau hloov mus rau saum npoo ntawm cov khoom thiab muab kev sib khi. Lub hauv paus ntawm kev tsim txom hauv cov txheej txheem no yog vuam arc nws tus kheej, vim tias nws tsis tsuas yog ua kom evaporation ntawm cov hlau thiab txau ntawm nws cov kab me me, tab sis kuj muaj zog tawg (ultraviolet, infrared thiab pom).
Thaum lub sijhawm ua haujlwm vuam, lub txim taws, pa taws thiab hluav taws xob yog tsim tawm
Txhua tus paub tias thaum lub sijhawm ua haujlwm ntawm tus kws tsim khoom, tsis tsuas yog lub txim taws ya mus, tab sis kuj muaj cov nplaim hluav taws xob uas muaj teeb nrog tsim kom tawg. Tom qab nws, cov nyhuv ntawm sunbeams tseem nyob - muaj lub teeb nyob rau hauv pem hauv ntej ntawm lub qhov muag rau qee lub sijhawm. Tab sis qhov no tsuas yog 15% ntawm hluav taws xob uas cov arc muab. Cov seem 85% yog lees paub los ntawm:
- Ultraviolet hluav taws xob (70%). Cov hluav taws xob nruab nrab thiab luv luv yog ua rau muaj teeb meem tawv nqaij thiab qhov muag. Xws li lub teeb ci ultraviolet muaj peev xwm nkag mus tob rau hauv cov ntaub so ntswg, ua rau pom kev tsis txaus siab ib ntus, mob siab (nrog kev xav "xuab zeb"), photophobia, mob ntawm cov nqaij mos ntawm lub qhov muag, hlawv ntawm daim tawv nqaij.
- Infrared hluav taws xob (15%). Nws tsis txaus ntshai tshaj li piv rau ultraviolet lub teeb, tab sis nws nqa lub zog thermal thiab tuaj yeem ua rau daim tawv nqaij thiab ua rau lub ntsej muag ntawm lub qhov muag, tom qab los ntawm o (photokeratitis).
Saib vuam tsis muaj daim npog tiv thaiv tshwj xeeb thiab tsom iav yog qhov phom sij heev, thiab qhov no tsis yog qhov dab neeg txhua. Tab sis qhov no tsis txhais tau hais tias, tau pom lub vuam ua haujlwm, koj yuav tsum kaw koj lub qhov muag thiab khiav mus - nws txhua tus nyob ntawm lub sijhawm ntawm kev xav thiab qhov deb mus rau arc. Yog li, yog tias tus neeg nyob ntawm qhov chaw deb tshaj 15 metres thiab saib lub teeb ntas rau ib lub sijhawm luv, tom qab ntawd cov hluav taws xob yuav cia li tawg, tsis muaj lub sijhawm mus cuag lub qhov muag, thiab, raws li, yuav tsis muaj peev xwm ua kom raug mob. Thiab yog tias koj yog 1 meter los ntawm arc, ces qhov kev cuam tshuam kev puas tsuaj ntawm kev phom sij yog kev tsis tuaj yeem, tshwj xeeb tshaj yog tias ib tug neeg saib vuam mus ntev dua 30 vib nas this.
Yuav tsum siv daim npog tshwj xeeb rau vuam siv.
Muaj qee qhov kev ntseeg ntau ntxiv txog kev phom sij ntawm vuam:
- Saib kev ua haujlwm vuam tuaj yeem ua rau dig muag. Qhov no muaj tseeb tiag, tab sis kev quav yeeb yaj kiab yog kho kom haum xeeb. Los ntawm nws tus kheej, hluav taws xob tsis ua qhov muag tsis pom, nws tsuas yog cuam tshuam cov ntsiab lus ntawm lub qhov muag, uas ua rau pom qhov tshwm sim ntawm cov kab mob (mob, photophobia, hluav taws xob cataract, puas tsuaj rau lub lens thiab retina). Qhov tsis muaj kev kho mob raws sij hawm ntawm cov teeb meem uas tau tshwm sim tuaj yeem ua rau cov dig muag tsis pom kev thiab ua tiav. Ib ntu ntawm kev soj ntsuam luv ntawm vuam feem ntau yuav ua rau muaj teeb meem ib ntus xwb.
- Nws yog qhov txaus ntshai mus saib lub vuam tsuas yog tias nws yog pem hauv ntej ntawm koj lub qhov muag. Qhov no yog ib qhov tswvyim hais ua dab tsi, vim qhov tsis zoo ntawm hluav taws xob yuav cuam tshuam rau tus neeg txawm hais tias lub arc los ntawm sab, thiab txawm tias qhov kev soj ntsuam tshwm sim los ntawm ib qho kev cuam tshuam sab hauv (qhov duab ci yuav cias nws thiab tseem poob rau hauv lub qhov muag).
-
Vuam yog txaus ntshai rau lub qhov muag tsis yog los ntawm hluav taws xob, tab sis kuj los ntawm txim taws. Qhov no yog qhov tseeb, vim hais tias thaum lub sijhawm ua haujlwm ntawm lub arc, qhov me me ntawm cov hlau tsis muaj hlau thiab cov nplaim taws ya tawm, muaj qhov kub siab. Yog hais tias lawv tau nkag mus rau hauv lub qhov muag, tom qab ntawd hlawv yuav tshwm sim kev mob, nrog kev mob siab, qhov hnov ntawm lub cev txawv teb chaws hauv lub qhov muag, txiav, liab thiab lacrimation.
Dross hauv qhov muag Thaum lub sijhawm vuam, ib qho me me ntawm molten hlau tuaj yeem nkag mus rau hauv lub qhov muag
Saib vuam tsis muaj qhov muag thaiv tshwj xeeb yog qhov txaus ntshai heev. Ua raws li lub sijhawm ntawm kev tshuaj xyuas thiab qhov deb mus rau arc, koj tuaj yeem tau txais ob qho tib si "me ntsis" ua ntej lub qhov muag, thiab kub hnyiab thiab ua rau lub qhov muag puas tsuaj.
