时至今日,武术仍未能很好地进入校园,其原因何在,如何从柔道、跆拳道、空手道的成功现代化和国际化当中寻求启发,成为紧迫论题。主要运用文献资料法,基于对学校武术历史、现状的反思和日韩武技现代化的启示,对我国学校武术的根本问题和根本方略做出探讨。研究认为,学校武术开展的现状不能实现中华民族赋予它的文化使命,日韩武技现代化的经验可为我们提供启示——将传统意义上的搏杀武技改造为一项现代文明搏击项目,该项目需满足几个趋势保证安全文明化、保持技击本质性、具有游戏趣味性、彰显民族独特性。在此基础上,做出武术以太极推手形式进入校园的提案。 相似文献

运用文献资料法和中国哲学诠释学方法,在"技道并进""德艺双馨"的优秀文化传统和"功夫所至即是本体"的哲学范式下,提出:武术功夫是一个三维合一的概念,其既涵摄本体与主体,亦包纳才艺与能力,还囊括了方法与规则。从"功力"角度看,功夫具备本体的性质,指的是类似禅、太极等理念在长时间实践中的现身性表达;从"功用"的角度看,功夫就是一种高级的搏击竞技能力或表演才艺;从"功法"的角度看,功夫表征了方法运用的得当。其蕴藏了:(1)神形共建;(2)在人伦日用中寻求终身技能的发展;(3)身体技艺与情感意志共同成长三层"元实践"哲学意蕴。功夫旨在塑造整体的人、具体的人和自我超越的人,这无疑与身体素养所强调的"身体锻炼与人格培养并举"的整体论哲学在逻辑上相贯通。武术功夫在语义和哲学内涵两个层面上与身体素养有着极强的互释性,属于中国本有的身体素养思想,这就使得功夫修炼具备了提升当代人身体素养和助推当今武术发挥更广义的教育价值之重要意义。 相似文献

This paper investigates the problem of observer-based decentralized control for a class of large-scale stochastic high-order feedforward systems with multi time delays. By using the homogeneous domination idea and constructing the implementable observer, the decentralized output-feedback controller design scheme is firstly proposed. Then, with the aid of stochastic time delay system stability theory, the globally asymptotically stable in probability of the closed-loop system is verified by selecting an appropriate Lyapunov–Krasoviskii functional. Finally, an example is provided to demonstrate the efficiency of the proposed design method. 相似文献

The hydraulic turbine governing system plays an indispensable role in maintaining the stability of electrical power system. In this paper, synergetic control theory is introduced to enhance the regulating ability of the hydraulic turbine governing system. For the purpose of describing the characteristics of objective system and deducing the synergetic control rule, a nonlinear mathematic model of a hydraulic turbine governing system with long tail race and two surge tanks is established. Furthermore, the nonlinear characteristic of the hydraulic turbine is described by six variable partial derivatives. For further investigation, the hydraulic turbine governing system is conducted to running under load condition when its coaxial generator connects to an infinite bus. Simulation experiments have been made under both load disturbance and three-phase short circuit fault conditions to compare the dynamic performances of proposed synergetic governing controller and classic PID controller. The results indicate that the proposed synergetic governing controller is an effective alternative in normal condition and a superior one in emergency. Moreover, the robustness of synergetic governing controller has also been discussed at the end of this paper. 相似文献

Most of the reported Lotka–Volterra examples have at most one stability interval for the delay parameters. Furthermore, the existing methods fall short in treating more general case studies. Inspired by some recent results for analyzing the stability of time-delay systems, this paper focuses on a deeper characterization of the stability of Lotka–Volterra systems w.r.t. the delay parameters. More precisely, we will introduce the recently-proposed frequency-sweeping approach to study the complete stability problem for a broad class of linearized Lotka–Volterra systems. As a result, the whole stability delay-set can be analytically determined. Moreover, as a significant byproduct of the proposed approach, some Lotka–Volterra examples are found to have multiple stability delay-intervals. To the best of the authors’ knowledge, such a characterization represents a novelty for having some insights in the population dynamics: in some situations, a longer maturation period of species is helpful for the stability of a population system. 相似文献

This paper contributes to the debate on the energy efficiency paradox according to which consumers fail to adopt cost-effective, energy efficient technologies over less efficient technologies and therefore fail to reduce energy consumption. Both traditional and behavioural theories are used to investigate the decision-making process of residential consumers with empirical evidence based upon a specially designed quasi-experimental survey of 784 households on the decision to connect to a district-heating system, a more energy efficient alternative to individual heating systems. The results suggest an internal discount rate of around 36 per cent for homeowners, a signal that consumers undervalue future energy costs. We also find the household’s decision to be negatively affected by years of payback up to around 7–8 years. Our findings suggest that neglecting consumer inattention and heuristics can lead to biases which cast doubt on the existence of the energy efficiency paradox. We believe that these results help to explain why some consumers are unlikely to invest in energy efficient technology, particularly those on low incomes. 相似文献

In this paper, we address the issue of sparse signal recovery in wireless sensor networks (WSNs) based on Bayesian learning. We first formulate a compressed sensing (CS)-based signal recovery problem for the detection of sparse event in WSNs. Then, from the perspective of energy saving and communication overhead reduction of the WSNs, we develop an optimal sensor selection algorithm by employing a lower-bound of the mean square error (MSE) for the MMSE estimator. To tackle the nonconvex difficulty of the optimum sensor selection problem, a convex relaxation is introduced to achieve a suboptimal solution. Both uncorrelated and correlated noises are considered and a low-complexity realization of the sensor selection algorithm is also suggested. Based on the selected subset of sensors, the sparse Bayesian learning (SBL) is utilized to reconstruct the sparse signal. Simulation results illustrate that our proposed approaches lead to a superior performance over the reference methods in comparison. 相似文献

This paper presents an optimal solution to asteroid soft landing problem, on the base of control technique and disturbance rejection mechanism. The control objective is to drive a probe to reach the surface of an asteroid with a desirable line-of-sight angle and zero velocity, eliminating the influence of external disturbance. Firstly, elementary technique is applied in the absence of disturbance to tackle the nonlinear optimal control problem. Secondly, the disturbance is estimated in the fast-estimation framework with explicitly bounded estimation error. Afterwards, an integrated control protocol is presented in a feed-forward structure by the aid of an additional variable-structure term to ensure stability under time-varying disturbance. Simulation results of the proposed approach compared with the results of elementary method and robust method are presented at the end of this paper, demonstrating the effectiveness of the proposed control protocol. 相似文献
