18. Ionizing hluav taws xob tuaj yeem nkag mus rau qhov chaw, tab sis tsis muaj hluav taws xob tsis tuaj yeem.
Yuav tsis muaj hluav taws xob ionizing puas tsim kev puas tsuaj?
Kev raug mob hnyav, ncaj qha ntawm cov hluav taws xob tsis-ionizing yuav ua rau muaj kev puas tsuaj rau cov ntaub so ntswg vim cua sov. Qhov no tsis yog ib txwm muaj thiab feem ntau ntawm kev txhawj xeeb hauv chaw ua haujlwm rau cov neeg ua haujlwm loj ntawm cov khoom siv hluav taws xob tsis muaj hluav taws xob thiab cov twj paj nruag.
Yuav siv hluav taws xob dab tsi los ua kom tsis muaj menyuam?
Gamma tawg sterilization yog daim ntawv nrov tshaj plaws ntawm kev ua kom tsis muaj hluav taws xob. [1, 4] Co-60 thiab, rau qhov tsawg dua, Cs-137 ua haujlwm raws li cov khoom siv hluav taws xob thiab kev puas tsuaj los tso tawm lub zog gamma rays. Cov hluav taws xob hluav taws xob tsim hluav taws xob yog qhov nkag tau zoo heev thiab tuaj yeem tua cov kab mob sib kis.
YYog UV teeb ionizing lossis nonionizing?
Non-ionizing hluav taws xobsuav nrog cov spectrum ntawm ultraviolet (UV), pom lub teeb, infrared (IR), microwave (MW), xov tooj cua zaus (RF), thiab qis heev. zaus (ELF).
Qhov twg hauv qab no yog qhov tsis zoo ntawm OPA ua tshuaj tua kab mob?
Nws cov haujlwm ntau dua li ntawm glutaraldehyde, thiab cov tshuaj tua kab mob siab tau ua tiav nrog lub sijhawm sib cuag ntawm 12 feeb ntawm lossis siab dua 20 ° C. Thawj qhov tsis zoo ntawm OPA yog qhov nws stains cov ntaub so ntswg thiab mucous daim nyias nyias grey.

Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Lub tshuab hluav taws xob loj npaum li cas rau qhov chaw nres tsheb tsis muaj hluav taws xob?
Nrhiav lub rhaub nrog BTU tso zis uas phim koj cov txiaj ntsig. Piv txwv li, yog tias koj qhov chaw nres tsheb tsis muaj hluav taws xob yog 484 square feet, koj cov qauv yog 484 / 200 x 9, 000, lossis 21, 780. Koj xav tau lub rhaub nrog tsawg kawg yog 21, 780 BTU tso zis.
Puas yog hluav taws xob hluav taws xob muaj ob qhov xwm txheej?
EM hluav taws xob yog lub npe vim nws muaj hluav taws xob thiab sib nqus teb uas ib txhij oscillate hauv cov dav hlau sib koom ua ke rau ib leeg thiab rau kev taw qhia ntawm kev nthuav tawm los ntawm qhov chaw. ✓ Electromagnetic tawg muaj ob qhov xwm txheej:
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
