Lub Neej Ntawm Cov Kabmob: Kev ntsuas lub neej ntawm ib pawg ntawm qhov pom zoo ib yam kabmob yog txhais raws li tus lej ntawm kev hloov pauv (lossis tus naj npawb ntawm cov xuab moos ntawm qhov nrawm nrawm) uas 90 feem pua ntawm ib pawg ntawm cov kabmob yuav ua kom tiav lossis ntau dua ua ntej thawj qhov pov thawj ntawm kev qaug zog tsis ua haujlwm. Nws tseem hu ua L10 lub neej.
Catalog life of bearing yog dab tsi?
Ib tus qauv qauv - tseem hu ua tus txheej txheem catalog. (ISO 281) - yog cov lus pom zoo ntawm kev suav cov kabmob . life. Cov tsis yog bearing load, rotational speed, dynamic load rating thiab bearing type.
Lub neej ntawm tus kabmob yog dab tsi?
Lub neej nruab nrab - nruab nrab lub neej ntawm pab pawg ntawm cov kabmob yog qhov nruab nrab - qhov chaw nruab nrab ntawm 4 thiab 5 npaug ntawm L10 lub neejLub nra tas li radial uas ib pab pawg ntawm cov kabmob tuaj yeem ua rau muaj kev cuam tshuam Kev ntsuas lub neej ntawm 1 lab kiv puag ncig ntawm lub nplhaib sab hauv (chaw nres tsheb thiab lub nplhaib sab hauv ruaj khov).
Yuav ua li cas ntsuas lub neej?
Kev ntsuas lub neej L10 yog lub neej qaug zog uas 90% ntawm cov pab pawg loj txaus ntawm cov kabmob sib xws ua haujlwm raws li cov xwm txheej zoo ib yam tuaj yeem yuav tsum tau txais los yog tshaj. Kev ntsuam xyuas lub neej L10 yog cov khoom pov thawj thiab siv tau zoo uas tuaj yeem siv los txiav txim siab qhov loj me uas tsim nyog kom tsis txhob qaug zog ua tsis tiav.
SKF bearings ntev npaum li cas?
Lub neej txee ntawm cov kabmob kaw
Lub sijhawm cia siab tshaj plaws rau cov kabmob SKF kaw tau raug txiav txim los ntawm cov roj nplua nyeem hauv cov kabmob. Lubricant deteriorates dhau lub sij hawm raws li kev laus, condensation, thiab sib cais ntawm cov roj thiab thickener. Yog li ntawd, cov bearings kaw yuav tsum tsis txhob muab khaws cia rau ntau tshaj peb xyoos
Pom zoo:
Dab tsi hauv qab no yog lub zog tsim cov khoom noj khoom haus?
Cov khoom noj uas muab lub zog feem ntau hu ua macronutrients ( carbohydrates, lipids, thiab proteins). Carbohydrates thiab proteins muab lub zog zoo sib xws rau ib gram ntawm zaub mov . Yuav ua li cas cov khoom noj tseem ceeb hauv qab no yog lub zog tsim tawm?
Qhov xwm txheej twg yuav tsum tau sau tseg hauv lub chaw tsim khoom phau ntawv teev npe?
Cov xwm txheej nrog cov menyuam yaus, qaug cawv lossis muaj teeb meem tus neeg saib xyuas yuav tsum tau sau rau hauv phau ntawv teev npe uas: suav nrog cov ntawv muag khoom, yog tias muaj. Kev cuam tshuam: thaum tus neeg rau zaub mov, tus thawj tswj hwm lossis tus neeg muaj ntawv tso cai ua pov thawj tias kev pabcuam rau tus neeg haus cawv raug txiav tawm thiab kom tus qhua tuaj txog hauv tsev yam xyuam xim .
Lub sijhawm koj lub neej thaum twg khoom noj khoom haus tseem ceeb?
Kev noj qab haus huv thoob plaws lub neej txhawb nqa noj qab nyob zoo cev xeeb tub, txhawb kev loj hlob ib txwm, kev loj hlob thiab kev laus, pab tswj lub cev qhov hnyav, thiab txo qhov kev pheej hmoo ntawm kab mob mus ntev. kev noj qab haus huv thiab kev noj qab nyob zoo .
Nws puas tuaj yeem tsim thiab tsim lub thoob dej yug ntses ua ib qho chaw nyob?
Zoo. Aquarium tu tus kheej yog hais txog ntau tshaj li kev saib xyuas qis xwb. Nws yog hais txog kev tsim kom muaj kev vam meej hauv dej ecosystem rau ntses, invertebrate, cog lub neej, thiab kab mob. Koj tsim lub thoob dej yug ntses li cas?
Nyob rau hauv chloroplast qab zib yog tsim nyob rau hauv ib tug compartment hu ua lub?
3. stroma - Cov kua dej ntom ntom hauv cov chloroplast uas nyob ib puag ncig lub thylakoid daim nyias nyias thiab koom nrog hauv kev sib txuas ntawm cov organic molecules los ntawm carbon dioxide thiab dej. Qab zib yog tsim nyob rau hauv lub stroma los ntawm cov enzymes ntawm Calvin voj voog Calvin cycle Calvin cycle, Calvin-Benson-Bassham (CBB) cycle, reductive pentose phosphate cycle (RPP cycle) los yog C3 cycle yog series ntawm biochemical redox cov tshuaj tiv thaiv uas ts
