Lub twj tso kua mis ncej foob yog ib qho tseem ceeb ntawm cov twj tso kua mis. Nws yog lub luag haujlwm los tiv thaiv cov kua dej los ntawm kev tawm ntawm lub twj tso kua mis. Lub twj tso kua mis lub tog raj kheej yog lub tshuab foob uas khaws cov kua dej uas muaj nyob hauv lub twj tso kua mis thiab tiv thaiv kom tsis txhob muaj qhov tshwm sim.
Lub foob foob feem ntau yog nyob ntawm qhov chaw uas lub twj tso kua mis ncej tawm ntawm lub casing. Nws yog tsim los tiv thaiv cov kua dej los ntawm kev khiav tawm ntawm lub twj tso kua mis nyob ib ncig ntawm lub ncej thiab mus rau ib puag ncig ib puag ncig. Qhov no yog ib qho tseem ceeb vim hais tias ib qho kev xau tuaj yeem ua rau cov khoom puas tsuaj thiab tsim kev nyab xeeb.
Cov twj tso kua mis ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws lus Txhua tus qauv tsim muaj nws cov yam ntxwv tshwj xeeb thiab cov txiaj ntsig, nyob ntawm daim ntawv thov thiab cov kua dej ua haujlwm.
Feem ntau, lub twj tso kua mis lub tog raj kheej yog tsim los ntawm ob qhov tseem ceeb: ib qho chaw ruaj khov, uas txuas nrog lub twj tso kua mis, thiab lub twj tso kua mis tig, uas txuas nrog lub twj tso kua mis. Thaum lub twj tso kua mis ua haujlwm, ib txheej nyias ntawm cov roj lubricating tau khaws cia ntawm ob yam khoom kom txo tau kev sib txhuam thiab hnav.
Nws yog ib qho tseem ceeb kom tsis tu ncua xyuas, tswj thiab hloov lub twj tso kua mis ntsaws ntsaws ruaj ruaj raws li lawv yuav tsum tau hnav dhau sijhawm. Kev tsis saib xyuas cov ntsaws ruaj ruaj tuaj yeem ua rau xau, siv hluav taws xob ntau ntxiv, thiab txo qis kev ua haujlwm.
Hauv cov ntsiab lus, cov twj tso kua mis ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws lus Kev txhim kho kom zoo, kev tshuaj xyuas, thiab kev saib xyuas ntawm cov ntsaws ruaj ruaj yog qhov tseem ceeb los xyuas kom meej tias cov khoom siv muaj kev nyab xeeb thiab ua haujlwm zoo.
