摘要：

The morphology of beta phase monoacid triacylglycerol crystals is derived schematically on a theoretical basis. The results of this theoretical morphology are compared with experimental growth forms. The theory used is based on the concepts of periodic bond chain (PBC), F-face and connected net, developed by Hartman and Perdok. The relative roughening transition temperature of F-faces is estimated using an Ising model. The theoretical morphologies are constructed using different criteria. The influence of the chain length of the hydrocarbon chains on the morphology is investigated. A flat needle-like habit with the needle axis parallel to the b-axis is predicted. This is in good agreement with the observed morphology.
