Purpose of the Research (described in the initial application, with a few modifications) Results1. To complete algorithms/programs in order to identify the magnetic spring function. Arrived at the expected stage.2. To study theoretically the accuracy of identification in the magnetic spring function in the static field. Arrived at the expected stage.3. To study experimentally the accuracy of identification in the magnetic spring function in the static field. Experimental apparati are completed and work is progressing.4. To identify experimentally the repulsing magnetic field via the eddy current. especially the ultra high speed object. Experimental apparati are completed and work is progressing.5. To study problems of nonlinear vibration, chaos in particular, running (flux shearing) resistance and vibration damping in the models of the previous items 3 and 4. Experimental apparati are completed and work is progressing.Derived Problems results6. Computer simulation of nonlinear vibrations.Arrived at the expected stage and many papers were published.7. Studies of accurate numeration and/or solutions as well as functions. Many extended problems were found and work is progressing.Plan for future reseaches It is concluded that an apparetus for achieving a transonic high speed corresponding to the previous item 4 is incomplete because of the difficulty of the over-stress in the rotating wheel. thus, we developed a method to neutralize the stress by blowing a gas from outside of the wheel with the pressure corresponding to the centrifugal stress. The basic design is completed, however, the construction of the system is postponed because of financial problems.

研究目的(在最初的申请中描述，有一些修改)结果1.完成算法/程序，以识别磁力弹簧的功能。达到了预期的阶段。从理论上研究静电场中磁弹簧函数辨识的准确性。达到了预期的阶段。实验研究静电场中磁弹簧函数辨识的准确性。实验仪器已完成，工作正在进行中。通过实验识别涡流产生的排斥磁场。尤其是超高速物体。实验仪器已完成，工作正在进行中。研究前面第三项和第四项模型中的非线性振动问题，特别是混沌问题，运行(磁通剪切)阻力和减振问题。实验装置已经完成，工作正在进行。对非线性振动进行了计算机模拟，达到了预期的目的，发表了大量的论文。研究精确的计算和/或解以及函数。对未来研究的规划得出的结论是，与前一项4相对应的实现跨音速高速的服装是不完整的，这是因为旋转车轮中存在过应力的困难。因此，我们开发了一种方法，通过从车轮外部吹出气体来中和应力，压力与离心力相对应。基本设计已经完成，但由于资金问题，该系统的建设被推迟。
