本文从观念、目的和定位以及散手规则等方面分析了在武术的继承和发展中存在的问题,认为武术改革首先要转变观念,明确目的定好位;其次把武术整合,对其规则进行修改,取消竞技比赛形式。这是中国武术走向二十一世纪,走向世界的先决条件。 相似文献

When we were young, we had dreams and expectations. We imagine things, we keep thinking about what we want to be, what we want to do, what makes us proud and happy and what we will become. We grew up, and things seemed like having its own way. We accept our success or failures and we move on. The rapid change, the need to do the urgent things, the works, the pressures and the failures, all kill part of our visions. Things have changed, but they cannot really take away the dreams. We still have to dream on, to visualize our desires, our wants, our vision of our future, even when we are considered too old for such things. 相似文献

This paper presents system design challenges and issues with sensing through walls at different standoff distances and wall types. Efforts for developing sense through the wall (STTW) systems, such as those undertaken by the US Army Technology Objective (ATO) program, aim at providing the soldier with situational awareness information before breaching a building in a military operations in urban terrain (MOUT) environment. STTW capabilities also support law enforcement and search and rescue applications. Since 2002, extensive evaluations of STTW technologies, most notably those performed by the Communications Electronics, Research, Development and Engineering Center (CERDEC) Intelligence and Information Warfare Directorate (I2WD), have been made to determine which technology could be the most viable solution. After conducting comprehensive studies, I2WD initiated several Phase I efforts and Phase II efforts. The purpose behind both efforts was to develop various STTW technology demonstrators under a 5 year ATO. Many lessons learned during the development of Phase I systems were incorporated into the considerations for Phase II developments. This paper discusses design challenges and issues with sensing through walls at different standoff distances and wall types through lessons learned and results from modeling and simulations performed by the Army Research Laboratory. 相似文献
