cov neeg muag khoom kev cai helical iav thawv qhov chaw

Cov iav spur thiab cov iav helical yog ob hom iav uas siv ntau hauv cov tshuab kho tshuab, txhua tus muaj nws tus kheej cov yam ntxwv thiab kev siv. Nov yog qhov sib piv ntawm ob qho no:
Spur iav:
1. Kev teeb tsa cov hniav: Cov iav spur muaj cov hniav spur sib luag rau lub iav axis. Qhov no ua rau cov hniav profile yooj yim thiab yooj yim rau kev tsim khoom.
2. Kev Ua Haujlwm Zoo: Cov iav spur paub txog lawv qhov kev ua haujlwm zoo vim yog kev sib cuag ncaj qha ntawm cov hniav iav, ua rau muaj kev poob hluav taws xob tsawg kawg nkaus thaum kis tau.
3. Suab nrov thiab kev co: Cov iav spur tsim ntau lub suab nrov thiab kev co, tshwj xeeb tshaj yog thaum muaj kev kub ceev, vim yog kev sib koom ua ke thiab kev sib cais ntawm cov hniav iav.
4. Daim Ntawv Thov: Cov iav spur feem ntau yog siv rau hauv cov ntawv thov uas qhov yooj yim, kev siv nyiaj tsim nyog, thiab kev ua haujlwm siab yog qhov tseem ceeb, xws li cov iav yooj yim, cov tshuab kev lag luam, thiab cov kis tau tus mob hauv tsheb.
Helical iav:
1. Kev teeb tsa hniav: Cov iav helical muaj cov hniav helical ntawm lub kaum sab xis rau lub iav axis. Cov hniav helical no tso cai rau kev koom tes maj mam thiab kev ua haujlwm du, ua rau muaj suab nrov thiab kev co tsawg dua.
2. Kev faib khoom thauj: Cov hniav helical ntawm cov iav helical ua rau nws faib cov khoom thauj kom sib npaug ntawm cov hniav iav, yog li ua tiav cov peev xwm thauj khoom siab dua thiab xa hluav taws xob du.
3. Kev Ua Haujlwm Zoo: Txawm hais tias cov iav helical yuav ua haujlwm tsawg dua li cov iav spur vim yog qhov kev txav ntawm cov hniav, lawv muab kev du thiab txo suab nrov thaum lub sijhawm ua haujlwm.
4. Daim Ntawv Thov: Cov iav Helical feem ntau yog siv rau hauv cov ntawv thov uas xav tau kev ua haujlwm du thiab ntsiag to, muaj peev xwm thauj khoom siab, thiab kev tswj hwm kev txav mus los meej, xws li cov tshuab hnyav, cov khoom sib txawv hauv tsheb, thiab cov kev sib kis hauv kev lag luam.
Hauv kev xaus, cov iav spur paub txog lawv qhov yooj yim, kev ua haujlwm zoo, thiab kev siv nyiaj tsim nyog, thaum cov iav helical muab kev ua haujlwm du dua, muaj peev xwm thauj khoom ntau dua, thiab suab nrov thiab kev co qis dua. Kev xaiv ntawm ob qho no nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov, suav nrog cov yam ntxwv xws li kev thauj khoom, qhov ceev, kev xav txog suab nrov thiab tus nqi.
