Therapeutic horseback riding have been believed as a good media to improve balance ability. We proceeded to do a case study, by the use of a mechanical horse made by Joba EU-6441, Matsushita Electric Industrial Co., Ltd., Japan. This mechanical horse is designed according to the movement pattern of a real horse. The seat is designed to move in a pattern based on the figure of eight. Many clinics begin to adopt the mechanical horses as treatment tools, but its effectiveness in children with ADHD remains unknown.

目前对於ADHD儿童平衡能力的训练及介入成效之研究较少，本研究以骑马治疗进行个案讨论，采用的骑马机(Joba EU-6441， Matsushita Electric Industrial Co。， Ltd。， Japan)是根据真实马运动时的动作模式所设计出来的，临床上认为骑马机有可增进平衡能力的功用，目前已逐渐被临床治疗师广泛使用，但对於骑马机的确切疗效仍没有研究加以证实，尤其是骑马机是否对於平衡能力或是感觉调节能力有所帮助等。

The mechanical property testing shows that the seamless PLLA tubes perform excellent radial strength,which indicates that the mechanical properties of biodegradable stents made of these tubes was supposed to be excellent.PLLA and its composites were first used in preparing seamless tubes as antecedency of laser-cut biodegradable coronary stents in china.Finite element analyses of the biodegradable coronary stent model indicate the explorative design basically meets the requirement of reasonable and applicable stents.There is not such kind of research yet in domestic.Optimum laser-cuttting parameters of CO2 laser was cauculated based on experiential formula,within it,biodegradable coronary stents,especially those with complex structure would be manufacutured from seamless tubes quickly by laser microprocessing with high consistency to the design model.The processing efficiency of the CO2 laser demonstrated in experiential formula by us will play an important guiding role in manufacturing biodegradable stents by laser-processing.Our stents that ascribed to laser-cutted,slotted tube stent are proved to be biodegradable, self-expandable and good biocompatible,basically reach the international level on the aspest of manufacturing procedures and design.

The paper consists of six chapters. Chapter One is the theoretical background, we review the course of mechanical theorem proving and briefly introduce the main mechanical theorem prover of the last decade, Among them, we stress on the Boyer-Moore theorem prover and its throretical foundation a computational logic. In Chapter Two, we discuss two theorem proving tactics. One is the rippling-out tactic, which is a tactic for manipulating the induction conclusion to enable the induction hypothesis to be used in its proof, because it extremely restricts the search space, so it has high efficiency.
