运用透射电镜技术，发现了三方晶系直氟碳钙铈矿（Synchysite）多型和微孪晶的存在，确定其中的多型有两种，即6R和3R多型，在3R多型中发现有微孪晶存在，这种微孪晶属（0001）孪晶面的面律（旋转）孪晶。由于直氟碳钙铈矿是钙铈氟碳酸盐系列矿物的一个端员组分，因此，对其多型和微孪晶的研究，有助于揭示该系列中间组分矿物多型和微孪晶的形成机理。
Using transmission electron microscopy, the existence of polymorphic and micro-twins of the tripartite Synchysite was discovered. There are two polymorphic types, 6R and 3R, found in the 3R polymorphism There are micro-twins present, which are (twins) twins of the micro-twin (0001) twin planes. Since bastserum cecalite is a member of the calcium-cerium-fluorocarbon series, the study of its polymorphic and micro-twins can help to reveal the polymorphic and micro Twin formation mechanism.
