In the "system knowledge and system capacity" oriented computer teaching innovation, how to reform the computer hardware experiments for improving the teaching quality, is the key of computer hardware courses innovation. In this paper, in order to address the problems existing in traditional computer hardware experiments teaching, we analyze the "system knowledge and system capacity" oriented computer hardware experiments innovation, and propose teaching innovation for computer hardware experiments based on mass collaboration. The proposed method includes: test bank construction mechanism based on mass collaboration; test item evaluation and performance assessment mechanisms based on Bloom’s model; teaching strategy optimization based on comprehensive evaluation. The construction results in Beijing Institute of Technology demonstrate the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

The slope protection made of engineering materials or the traditional ecological slope protection will disturb river slopes to a certain extent， which will change the original habitat and endanger the river ecological system at different levels.Aiming at this problem， a new type of implantable ecological slope protection was developed. This kind of slope protection is mainly made of surplus sludge from municipal sewage treatment plants. CaO and MgCl2were used as the microbial inactivating agent and gelatinizing agent. The above materials were mixed with appropriate grass seeds and certain amounts of water to produce implantation mud(IM).Driven by pumps， the IM was injected into the soil under the earth surface from 10cm to 50cm through a rapidly rotating(1000r/min) injector. The grass seeds would sprout in the IM. About 20 days later， the grass would grow and the ecological slope protection would come into being. On the one hand， this method could take advantage of the surplus sludge’s water-retaining property and fertilizing effect; on the other hand， the special rotating injection technology was expected to have less disturbance to the surface soil. Therefore， this kind of ecological slope protection could not only keep slope stability but also conserve habitats perfectly， which would be beneficial for the sustainable and healthy development of the river ecosystem.
