Dareerayaasha noocee ah ayaa ku habboon cabbirayaasha socodka Doppler ee Clamp-On?

Mitirrada socodka Doppler ee isku xiranwaxay si gaar ah ugu habboon yihiin dareerayaasha ay ku jiraan xaddi cayiman oo kala firdhiyeyaal acoustic ah, iyagoo ku tiirsan mabda'a saamaynta Doppler si loo cabbiro xawaaraha socodka iyadoo la ogaanayo isbeddellada soo noqnoqda ee mowjadaha dhawaaqa ee ay ka muuqdaan kala firdhiyeyaashu (tusaale ahaan, walxaha, xumbo) ee dareeraha ku jira. Hoos waxaa ku qoran noocyada dareeraha gaarka ah iyo xaaladaha muhiimka ah ee loo adeegsado:

Noocyada Dareeraha ee Ku Habboon ee Aasaasiga ah
1. Dareerayaal leh Walxaha Adag
Warbaahinta Caadiga ah:
Bulaacadda, wasakhda, saxarka macdanta, saxarka warqadda, biyaha wasakhda warshadaha (oo ka kooban walxo sida dhoobada, qashinka, fiilooyinka, oo caadi ahaan leh cabbir walax ah ≥30 μm).
Dareerayaasha ku jira walxaha ku jira warshadaha cuntada (tusaale ahaan, casiirka miraha oo leh saxarka, maraqa, cabitaannada ku jira hadhuudhka).
Joojinta warshadaha kiimikada (tusaale ahaan, isku darka walxaha kiciya, walxaha midabka leh).
Shuruudaha Muhiimka ah:
Fiirsashada walxaha waa inay ahaataa ≥100 ppm si loo hubiyo calaamadaha milicsiga dhawaaqa oo ku filan.
Impedance-ka acoustic-ga ee walxaha waa inuu si weyn uga duwanaadaa kan dareeraha (tusaale ahaan, walxaha adag waxay muujiyaan saameyn milicsi oo wanaagsan sababtoo ah kala duwanaanshaha impedance-ka ee biyaha).
2. Dareeraha leh xumbo
Warbaahinta Caadiga ah:
Socodka laba-waji ee gaaska-dareere ah (tusaale ahaan, dareerayaasha habka warshadaha oo leh xumbo hawo leh, dareerayaasha halsano biirka).
Dareere la walaaqay ama la hawo geliyay (tusaale ahaan, wasakh ka timaadda haamaha hawo-qaadashada ee daaweynta biyaha wasakhda ah).
Tixgelinno:
Xumbooyinku waa inay si isku mid ah ugu kala firdhaan dareeraha, iyagoo ka fogaanaya "kooxaha gaaska" ama gaaska aan xad-dhaafka ahayn (taas oo keeni karta kala firdhinta calaamadaha aan degganayn).
3. Dareeraha aan miridh lahayn ama aan midab lahayn
Xaaladaha Caadiga ah:
Dareeraha halkaas oo hababka cabbirka indhaha (tusaale ahaan, mitirrada socodka birlabta) aysan waxtar lahayn sababtoo ah marin-u-helid liidata (tusaale ahaan, xalalka kiimikada ee midabka madow, biyo dhoobo ah).
Baastada ama emulsions-ka warshadaha cuntada (tusaale ahaan, maraqa shukulaatada, saliidaha emulsified).
