Phosphine yog tsim los ntawm qhov kev txiav txim ntawm lub hauv paus muaj zog los yog dej kub ntawm cov phosphorus dawb los yog los ntawm cov tshuaj tiv thaiv dej nrog calcium phosphide (Ca3P2). Phosphine yog structurally zoo li ammonia (NH3), mas phosphine Nws yog ib qho kuab tshuaj tsis zoo dua li ammonia thiab tsis tshua muaj soluble hauv dej.
Tib neeg kuj nug, phosphine npaj li cas?
Laboratory kev npaj : Nws yog feem ntau tau los ntawm boiling dawb phosphorus nrog 30-40% tov ntawm caustic soda nyob rau hauv aninert cua ntawm CO2. Phosphine Yog li tau txais yog impure. Dej nkag mus rau hauv lub thawv los ntawm hauv qab thiab reacts nrog calcium carbide thiab calcium phosphide muab acetylene thiab phosphine.
Tsis tas li ntawd, phosphine gas txaus ntshai npaum li cas? Raug rau txawm me me ntawm phosphine tuaj yeem ua rau mob taub hau, kiv taub hau, xeev siab, ntuav, raws plab, tsaug zog, hnoos, thiab hauv siab nruj. Kev raug mob hnyav tuaj yeem ua rau poob siab, convulsions, coma, lub plawv dhia tsis zoo, thiab lub siab thiab lub raum puas.
Ua raws li qhov xav tau, phosphine roj tua koj li cas?
Nco ntsoov phosphine Nws muaj peev xwm tawg tau hauv huab cua thiab tuaj yeem autoignite nyob ze qhov kub thiab txias. Phosphine yog tshuaj lom heev rau cov kab mob aerobically ua pa, tab sis tsis yog rau cov kab mob anaerobic lossis metabolically dormant kab mob. Yog li, nws tuaj yeem siv rau tua kab kab tsuag nyob rau hauv grain, tsis muaj kev cuam tshuam grain viability.
Kev siv phosphine yog dab tsi?
DESCRIPTION: Phosphine yog siv nyob rau hauv cov khoom siv hluav taws xob no los qhia phosphorus rau hauv siliconcrystals. Nws kuj yog siv los ua fumigant, polymerizationinitiator thiab ua ib qho nruab nrab rau kev npaj cov nplaim hluav taws ntau. Phosphine muaj ntxhiab tsw ntawm qej ordecaying ntses tab sis yog tsw ntxhiab thaum ntshiab.

Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Yuav ua li cas calibrate Starfrit tshuav nyiaj li cas?
Nrhiav qhov khawm calibration ntawm lub ntsuas qhov hnyav digital. Nws feem ntau nqa ib qho ntawm cov luam tawm hauv qab no: "Cal," "Function," "Mode," lossis "Cal/Mode." Tam sim no nias lub pob no kom txog thaum tus lej tshwm ntawm qhov ntsuas tig mus rau "0," "000," lossis "Cal." Hauv qhov no, qhov ntsuas yuav tsum nyob hauv hom calibration
Yuav ua li cas koj pom tus qauv sib txawv thiab txhais li cas ntawm Excel?
Standard deviation yog ib qho kev ntsuas ntawm ntau npaum li cas variance muaj nyob rau hauv ib pawg ntawm cov zauv piv rau theaverage (txhais tau tias) ntawm cov zauv. Txhawm rau xam qhov sib txawv ntawm Excel, koj tuaj yeem siv ib qho ntawm ob txoj haujlwm tseem ceeb, nyob ntawm cov ntaub ntawv teev. Yog tias cov ntaub ntawv sawv cev rau tag nrho cov pejxeem, koj tuaj yeem siv STDEV. Pfunction
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
