Cov iav fwj yog cais los ntawm cov duab

(1) Kev faib tawm los ntawm cov duab geometric ntawm iav fwj
① Round iav fwj. Qhov hla ntawm lub raj mis yog puag ncig. Nws yog hom lub raj mis uas siv ntau tshaj plaws nrog lub zog siab.
② Square iav fwj. Qhov hla ntawm lub raj mis yog square. Hom lub raj mis no tsis muaj zog dua lub raj mis puag ncig thiab nyuaj rau kev tsim khoom, yog li nws siv tsawg dua.
③ Curved iav fwj. Txawm hais tias tus ntoo khaub lig yog puag ncig, nws yog nkhaus hauv qhov siab qhov siab. Muaj ob hom: concave thiab convex, xws li vase type thiab gourd type. Cov style yog tshiab thiab nrov heev nrog cov neeg siv.

(2) Kev faib tawm los ntawm kev siv sib txawv
① iav fwj rau cawv. Cov zis ntawm cawv yog loj heev, thiab yuav luag tag nrho nws yog ntim rau hauv iav fwj, feem ntau yog puag ncig iav fwj.
② Txhua hnub ntim iav fwj. Feem ntau yog siv los ntim ntau yam khoom me me txhua hnub, xws li tshuaj pleev ib ce, number case, kua nplaum, thiab lwm yam. Vim muaj ntau yam khoom, lub raj mis zoo li thiab cov foob kuj muaj ntau yam.
③ Cov kaus poom. Cov kaus poom zaub mov muaj ntau hom thiab cov khoom siv loj, yog li nws yog kev lag luam ntawm tus kheej. Lub raj mis dav dav feem ntau yog siv, nrog lub peev xwm ntawm 0.2-0.5L.
④ Kho mob iav fwj. Cov no yog cov iav fwj siv los ntim cov tshuaj, nrog rau cov xim av ntswj lub qhov ncauj me me lub qhov ncauj fwj nrog lub peev xwm ntawm 10-200mL, infusion fwj nrog lub peev xwm ntawm 100-1000mL, thiab kaw tag nrho ampoules.
⑤ Tshuaj reagent fwj. Siv los ntim ntau yam tshuaj reagents, lub peev xwm feem ntau yog 250-1200mL, thiab lub raj mis lub qhov ncauj feem ntau ntsia hlau lossis hauv av.
