Cov tshem tawm ntim Cov tshuaj X yog 0.5mL / 40mg. Yog hais tias qhov xav tau concentration yog 4mg hauv 1mL, ces 20mL yog xav tau rau 80mg ntawm tshuaj X. Yog hais tias 40mg displaces 0.5mL ntawm cov tshuaj, nws txhais tau tias 80mg displaces 1mL. 20mL - 1mL = 19mL ntawm diluent xav tau.
Tsis tas li ntawd, tus nqi hloov pauv ntawm cov tshuaj yog dab tsi?
Tus nqi khiav tawm tuaj yeem txhais raws li qhov ntim ntawm tshuaj uas displaces 1 gram ntawm suppository puag. piv txwv li, qhov ntim ntawm pwm feem ntau tseem nyob tas li thiab tsis tuaj yeem hloov pauv. Thaum twg peb ntxiv tshuaj los yog lwm yam excipients rau lub hauv paus tshuaj occupies ib co ntawm qhov chaw thiab displaces tej yam kom muaj nuj nqis ntawm lub hauv paus.
Ib sab saum toj no, kev suav tshuaj yog dab tsi? xam tus nqi ntawm cov khoom yuav tsum tau ua ib yam khoom ntawm. ib lub zog hais. Taw qhia. Pharmaceutical kev npaj muaj ntau cov khoom xyaw sib txawv hauv ib lub tsheb los tsim cov khoom. Cov khoom xyaw thiab cov tsheb uas siv rau hauv ib yam khoom tuaj yeem yog khoom, kua lossis roj.
Displacement volume yog dab tsi?
Cov ntim ntawm hloov chaw kua yog sib npaug rau cov ntim ntawm ib yam khoom immersed nyob rau hauv ib tug kua los yog ib feem ntawm cov ntim hauv qab ntawm qhov chaw ntawm cov khoom ib nrab submerged hauv cov kua.
Kuv yuav xam qhov kev hloov pauv li cas?
Rau xam kev khiav tawm , tsuas yog kos ib vector los ntawm koj qhov chaw pib mus rau koj txoj haujlwm kawg thiab daws qhov ntev ntawm kab no. Yog tias koj txoj haujlwm pib thiab xaus yog tib yam, zoo li koj txoj kev ncig 5K, ces koj hloov chaw yog 0. Nyob rau hauv physics, hloov chaw yog sawv cev los ntawm Δs.
