摘要: 构造煤和高温高压实验变形煤的EPR实验结果,充分显示了变形煤的EPR参数具有随Ro,max的增大而呈现规律性演化的特征,在Ro,max〉4%以后煤结构演化机理向拼叠作用的转化在实验变形煤和构造煤中也有很好的体现。但是,变形煤Ro,max的增大除与温度和围压条件有关外,还深刻地受到定向压力或构造应力的影响,尤其是对镜质组反射率各向异性的增强、煤大分子结构有序畴及定向性的增大更具有极为重要的控制作用。
Abstract: Based on the current condition of high education, the necessity and possibility of developing multimedia title as electronic textbooks are discussed, and the main characters of the new born textbooks is summarized. The key steps and main designing objectivs of multimedia titles, taking “Earth Sciences” as an example, are introduced, in which the integrity of knowledge and various forms of expression are stressed.
