The single teaching mode, simple accumulation of teaching materials, low intelligence, small amount of visiting volume, and low usage rate, etc, make the main problems in teaching.
Thus the teacher should not only supply teaching materials, but also organize and guide carefully each teaching step, including creating learning situation on line , guiding learning strategy, interaction and feedback.
Application of web data mining technology in online education Nowadays Web Data Mining Technology has been widely used in various fields such as business affairs, medicine science, the Science and Engineering etc.
With the help of these data, the system will automatically make comprehensive analysis and decide whether the teaching materials, the depth and scope are suitable, whether the teaching medium is suitable to the teaching materials and teaching objects, whether the teaching hour is proper and whether the teaching strategy is proper.
Conclusion The famous educator Blum’s learning theory goes like this: “Almost all the students can finish work or reach the learning goals as long as the teachers provide the students with appropriate materials, moderate help and sufficient time in teaching at the same time.”

Introduction C/C composite has become a new ultra-high-temperature structural material which is the focus of research and development in the field of new materials because of its excellent performance, such as high specific strength and modulus, high thermal shock resistance, low-density, low ablation rate etc.
Because the forming structure of C/C composite material is quite complex and its processed surface frame is not just made through cutting out, its theoretical surface roughness can not be figured out by the formula for materials with uniformity and continuity [11].

A variety of materials have been used in pilot tests, including iron, peat, and bone char.
Essentially, these materials either absorb the metals or precipitate them, similar to soil stabilization and precipitation technologies.

Introduction RDX is widely applied as a significant industrial explosive due to its excellent advantages, such as superior detontion performances, abundant raw materials, simple preparation method, and so on.
Therefore, the research for drying technological conditions of RDX has remarkable significance for further study of drying, producing, storage technology of RDX and other energetic materials.
