Nws kuj tseem siv tau los stain hlwb uas muag heev dhau los ua kom sov. Peb siv nigrosin ua raws li peb qhov tsis zoo stain. Qhov no txhais tau hais tias cov stain yooj yim muab ib qho hydrogen ion thiab ua rau tsis zoo. Txij li qhov saum npoo ntawm cov kab mob feem ntau yog qhov tsis zoo, lub xov tooj ntawm tes ua rau cov stain.
Tsis tas li ntawd, lub hom phiaj ntawm kev siv qhov tsis zoo yog dab tsi?
Lub ntsiab lub hom phiaj ntawm Tsis zoo staining yog kawm txog cov duab morphological, qhov loj thiab kev npaj ntawm cov kab mob hlwb uas nyuaj rau stain . np: spirilla. Nws kuj siv tau rau stain cov hlwb uas muag heev dhau los ua kom sov-kho.
Tsis tas li ntawd, koj yuav ua li cas rau Nigrosin stain? Mix 1 feem (0.1 mL) staining tov nrog ib tug sib npaug ntim (0.1 mL) ntawm phev. Tom qab 1-2 feeb, ib qho smear yog ua, cua qhuav, thiab tshuaj xyuas nyob rau hauv ib tug tsis zoo theem-zoo microscope. Sib tov 1 tee dej phev nrog 2 tee ntawm eosin tov. Tos li 15 s thiab ntxiv 3 tee ntawm 100/gL ntawm nigrosin ua daws.
Kuj paub yog, ob lub hom phiaj ntawm kev kho cua sov yog dab tsi?
Teb thiab piav qhia: Ob lub hom phiaj ntawm kev kho cua sov yog: Tua cov microbes. Cov kab mob muaj sia muaj cov enzymes uas tuaj yeem rhuav tshem cov kab mob.
Puas yog Nigrosin acidic lossis yooj yim?
Yog hais tias cov xim ntawm cov dye nyob rau hauv qhov zoo ion, raws li nyob rau hauv cov ntaub ntawv saum toj no, nws yog hu ua a yooj yim dye (piv txwv: methylene xiav , siv lead ua violet , safranin). Yog tias qhov xim xim yog nyob rau hauv qhov tsis zoo them ion, nws yog hu ua an acidic dye (piv txwv: nigrosin ua , congo liab).

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
