The mechanical behavior of Shape Memory Alloys material is tested, and the constitutive model of the SMA is established. A kind of SMA combined rubber isolator is developed, and the isolation effect of the SMA combined rubber isolator for long-span bridge and tall building structures is numerically simulated, from which the adaptive isolation performance and the self-restoring capacity of the SMA combined rubber isolator are verified. A kind of SMA damper is developed, the mechanical behavior of the SMA damper is tested, and the model of restoring force of the SMA damper is established. The theory and method of adaptive control based on the SMA damper for the long-span bridge are built, and the effectiveness and reliability of the adaptive control for the long-span bridge using the SMA damper are verified through numerical simulation and model test. The MRF-04K type magnetorheological damper is developed, the mechanical behavior of the MR damper is tested, and the model of restoring force of the MR damper is established. The theory and method of adaptive control based on the MR damper for the long-span bridge and tall building structures are built, and the effectiveness and reliability of the adaptive control for the long-span bridge and tall building structures using the MR damper are verified through numerical simulation and model test. In addition, the theory and method of sub-structural damage identification for long-span bridge are derived, the influence of soil-structure dynamic interaction on the seismic isolation and control effects with different isolation and control measures and the damage responses and the sliding base-isolation of large structures under the excitation of underground explosion are investigated.

The educational technology has the very intense practical orientation, but because this practical orientation is too powerful, it causes the researchers of educational technology can be unable to stop to think some basic theory questions, and be far away from asking educational technology some ultimate questions about educational technology. So it has caused that afer semicentennial developing educational technology still exit some questions such as confusing, the reality helpless, deficient theory, although it has obtained many encouraging performance, but it is unsuitable that educational technology is the commanding point of education reform and the breach status. Facing these conditions, educational technology needs carry on reviewing and looking up in historical and reality multiple field, needs integrate and conclude for obtained studying results, needs reflect on own level, and need to have the big breakthrough in the discipline elementary theory construction.

教育技术具有非常强的实践价值取向，但这种实践取向的过于强大往往使得教育技术的研究者们无法停下来思考本领域一些基本的理论问题，因此直接导致了教育技术学在经历了半个多世纪的学科建设历程之后，尽管取得了诸多可喜的成绩，但是依旧存在理论与实践研究的诸多问题，这对于面临新技术的发展和世界范围的教育改革浪潮而给予的教育技术作为教育改革的制高点和突破口的地位是极不相称的，教育技术学迫切需要在历史与现实的多重视野中进行回顾与前瞻，对已经获得研究成果进行综合和归纳，需要对学科自身进行深层次反思。
