Five factors as the motive force for the tourist development in guizhou karst terrain were proposed . the growth pole of tourist economy in guizhou karst terrain was defined in the initial use of the shift-share analysis . in the end, a tourism economic circle of guizhou karst terrain was constructed, as guiyang, anshun and zunyi being the first-level tourist circle, high graded roads as well as national and provincial highways being the axis, and the kernel layer, hinterland layer, radiation layer and extension layer of the tourist economy being the spatial radius 通过对区域旅游整合模式的概述,结合贵州省情,选择了适合贵州喀斯特地区旅游业发展的“点-轴-圈”模式;提出了贵州喀斯特地区旅游发展的五个动力因子;首次采用“份额?偏离分析法”确定出贵州喀斯特地区旅游经济增长极;最后以贵阳、安顺、遵义为一级旅游中心,以高等级公路、国道、省道为轴线,以旅游经济的核心层、腹地层、辐射层和扩展层为空间半径,构建出贵州喀斯特地区旅游经济圈。
Then we use a general architecture model of distributed system for reference, by adding a part of non-real-time kernel in the kernel layer, we ameliorate the architecture model and apply it to frame the naval chain of command . in order to adjust demand of naval chain of command, we boost the general real-time transmission protocol by adding measures to the old protocol in the aspect of data transferring and reliability by software, after we call the improved protocol dynamic real-time transmission protocol . as an innovation in real-time performance research and design, we try to improve the real-time performance by using capability of both vxworks and real-time transmission protocol furthest 文中首先介绍了实时系统和分布式系统的基本理论,然后提出了一种新的分布式实时系统结构模型,并应用新模型进行了舰艇指控系统的设计,论文针对舰艇系统的应用特殊性对已有的实时通信协议进行了改进,扩充了数据传输和可靠性处理的部分,在文中称改进后的协议为动态实时传输协议,然后应用vxworks实时操作系统和动态实时传输协议进行舰艇指控系统中进行实时任务和实时传输的研究和设计,最后对实时性研究方案进行了仿真试验并取得了较好的效果。
