CONT

Pondération par les flux et les volumes. En ce qui concerne l’homogénéisation, on est amené à pondérer les flux par les volumes pour respecter les flux moyens, et à pondérer les sections efficaces par les produits des flux par les volumes pour respecter les taux de réaction. En ce qui concerne la condensation, les règles sont les mêmes en remplaçant «volumes» par «intervalles de léthargie».
