KWB Pellet Txoj kev. Txoj kev no siv cov cuab yeej uas alkali halides ua yas thaum raug lub siab thiab tsim ib daim ntawv uas pob tshab hauv cheeb tsam infrared. Potassium bromide ( KBr ) yog qhov feem ntau alkali halide siv hauv pellets.
Cov lus nug tseem yog, vim li cas KBr siv los ua cov pellet?
Potassium bromide ( KBr , spectroscopic qib) feem ntau yog siv raws li cov khoom siv qhov rais vim nws yog pob tshab hauv IR, ntawm 4000-400 cm-1. Xwb, cov qauv tuaj yeem ntim hauv ib KBr matrix thiab nias rau tsim ib pellet uas yog ces analyses.
Ib tug kuj nug, vim li cas KBr IR tsis ua haujlwm? Cov khoom feem ntau yuav tsum tau diluted nrog cov IR - inactive KBr thiab nias rau qhov paub zoo " KBr - pellet." Txawm li cas los xij, ob hom kev ntsuas kev ntsuas muaj lawv qhov tsis zoo: cov kua cell yuav tsum tsis muaj npuas npuas thiab tsis yooj yim los ntxuav. KBr yog hygroscopic thiab yog li tsis yooj yim rau lis thiab khaws cia.
Tsis tas li ntawd, vim li cas Potassium bromide siv hauv infrared spectroscopy?
Potassium bromide yog pob tshab los ntawm ze ultraviolet mus rau ntev-yoj infrared wavelengths (0.25-25 µm) thiab tsis muaj qhov tseem ceeb ntawm cov khoom siv kho qhov muag hauv nws cheeb tsam kev sib kis siab. Nws yog siv dav li infrared optical windows thiab cov khoom siv rau kev dav dav spectroscopy vim nws qhov dav spectral ntau.
KBr siv rau dab tsi?
Rau ntau tshaj ib puas xyoo, poov tshuaj bromide, los yog KBr , ua siv hauv tib neeg thiab veterinary tshuaj raws li ib qho tshuaj tiv thaiv qaug dab peg. Phenobarbital, los yog PB, kuj tau siv rau xyoo los kho mob qaug dab peg. Txawm hais tias ob qho tib si 'cov keeb kwm ntev ntawm kev siv ntau, tsis tau pom zoo los ntawm FDA los kho mob qaug dab peg hauv tib neeg lossis tsiaj.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
