Abstract

Sposób określania morfologii koksów i karbonizatów, polega na analizie mikroskopowych zgładów koksu z jednego ujęcia mikroskopowego przy powiększeniu korzystnie 100-krotnym w świetle odbitym, zwykłym i białym. Początkowo tworzy się obraz binarny, czarno-biały przez zwiększenie kontrastu pomiędzy fazą litą substancji skoksowanej a przekrojem porów, a następnie tworzy się obrazy o wzmocnionym efekcie anizotropowym w świetle spolaryzowanym z płytką opóźniającą lub kontrastem interferencyjno-różniczkowym, zwiększając powiększenie wielokrotnie, korzystnie 5-krotnie. Z kolei w oparciu o obrazy o wzmocnionym efekcie anizotropowym, określa się wektory gradientu barwy szarej w obrębie wyizolowanych tekstur i oblicza poszczególne wskaźniki włóknistości, a następnie wylicza wskaźnik uśredniony w formie jednej niemianowanej wartości na podstawie prawa addytywności liniowej, przy uwzględnieniu wagi w postaci udziałów objętościowych, wyznaczonych na drodze wcześniejszej analizy ilościowej tekstur, wymiary fraktalne wyznacza się zarówno w oparciu o obrazy binarne i obrazy ze wzmocnionym efektem anizotropowym.
