Based on geological model of deposits and by means of CAD method,the authors put forward the building method of layered opencast mining geological model, whose layers are composed of bench.
建立以台阶为单元的分层式矿床开采地质模型的方法。
Three-dimensional ledges were observed on the broad faces and at the tip of bainitic plates, which proves the real existence of ledges.
为探讨铜合金的贝氏体相变机制，用透射电镜研究了三种Ｃｕ－Ｚｎ－Ａｌ合金贝氏体的精细结构，在贝氏体片条的宽面及生长前端均观察到三维形态的台阶，表明台价是客观存在的实验事实。
The results show that all the initial bainites formed in different alloys at different temperatures are with three-dimensional ledges on the broad faces and/ or at the growth edges of α1 plates but without internal stacking faults, which proves that ledges exist generally on bainites in Cu-Zn-Al alloys and that the growth of bainites is govern.
结果发现，三种合金在不同温度形成的贝氏体初生态的宽面及端面均存在三维形态的台阶，但无层错亚结构，表明台阶在Ｃｕ－Ｚｎ－Ａｌ合金贝氏体中是普遍存在的，贝氏体的生长属扩散控制的台阶长大机制。
