通过对相关史学资料进行归纳、分析,对导引与道、释、武、医文化体系下的生命修炼术的联系性做了辨析,对导引发展源流从纵向的时间和横向的空间进行梳理,对导引概念进行阐释,对由此演化而来的当代使用较频繁相关概念进行了辨析,揭示了导引的核心特质,以及近似概念之间的相互关系。研究认为,导引在几千年的发展中,从时间角度历经了萌芽期、成长期、高峰期、演变期和模糊期等;从空间角度演化为医学导引、道家修炼、佛教禅定、武术内功等不同文化派系下的理论与实践体系;气功、健身气功、导引养生功以及传统体育养生等当代概念均源自古代导引,其概念属性与演变期的生命修炼技术更为接近,与古代导引存在差异。探究概念属性,辨析概念差异与发展源流,对于民族传统体育学科教学及科研具有理论参照价值。

针对低压大电流DC-DC变换器负载经常变化的特点,以动态过程输出电压超调量最小和调节时间最短为目的,提出了一种改善DC-DC变换器动态性能的数字控制方式。将变换器在负载变化时的暂态过程分为两个阶段,在每个阶段内对占空比进行直接设置,使开关处于一直导通或一直关断的状态,通过计算两个阶段转折点的输出电压并与采样电压比较以决定开关的状态。该控制方式在负载突变时和计算开关状态时间的最优控制方式有同样的性能,而算法的实时计算量却大幅降低。实验结果表明分段控制可以有效改善DC-DC变换器的动态性能。
