TOPTITECH txheeb xyuas plaub qhov yooj yim pom cov txheej txheem rau cov kua uas dhau los ntawm cov khoom ntxeem tau:
Kev tshuaj ntsuam saum npoo: Cov khoom me me loj dua qhov pore loj ntawm cov khoom siv yog thaiv ntawm qhov chaw ntawm cov khoom, zoo ib yam li kev tshuaj ntsuam.
Kev tshuaj ntsuam tob: Cov khoom uas loj dua qhov pore channel raug thaiv ntawm qhov nkhaus lossis constricted qhov chaw ntawm cov channel.
Sib sib zog nqus pom: Cov khoom me me, txawm tias qhov me me dua li qhov pore loj ntawm cov channel, dhau los ntawm cov txheej txheem sib sib zog nqus ntawm cov khoom thiab khaws cia rau hauv cov khoom vim yog cov hlau fibers lossis cov hmoov hmoov uas ua rau cov khoom ntxeem tau.
ncuav mog qab zib lim: Cov khoom sib sau ua ke ntawm cov khoom ntxeem tau los ua ib txheej tuab ntawm cov ncuav mog qab zib lim, thiab muaj me me los yog tsis muaj qhov to. Yog hais tias qhov loj me me yog qhov loj dua qhov pore loj ntawm cov khoom, lub ncuav mog qab zib pom zoo ib yam li kev tshuaj ntsuam saum npoo thaum pib. Txawm li cas los xij, feem ntau, qhov me me me dua qhov pore loj ntawm cov khoom siv, thiab cov khoom sib txuas ua ke ntawm qhov pore qhib thiab maj mam loj hlob mus rau hauv lub ncuav mog qab zib lim. Nyob rau hauv cov txheej txheem tom ntej ntawm ncuav mog qab zib pom, lub ncuav mog qab zib lim nws tus kheej ua cov lim, thiab cov txheej txheem pom thiab kev ua haujlwm tsis zoo yog tswj los ntawm nws. Txij li feem ntau ntawm cov khoom siv lim dej muaj qhov me me me dua qhov pore loj ntawm cov khoom siv, qhov pore loj ntawm "tshiab lim" (khoom qab zib) tsim los ntawm cov khoom no me dua li ntawm cov khoom lim nws tus kheej. Los ntawm kev siv lub ncuav mog qab zib pom zoo no, cov khoom siv nrog cov khoom me me dua li qhov pore loj ntawm cov khoom siv tuaj yeem lim tau siv cov ntaub ntawv loj pore loj.
