体育——农民群体中的短板与发展对策
Sports—The Short Board and the Development Countermeasures in Farmers
 [PDF]


Advances in Physical Sciences (APS) , 2015, DOI: 10.12677/APS.2015.32005
Abstract:
本文主要运用文献资料法、观察法、访问调查法,从农村农民的生活现状进行出发对体育在农民群体中欠发展的原因进行分析和解剖,得出了体育仍然是农民群体中的短板,农民对体育的认识仍然淡薄,是全民健身发展的一个滞后环节,并提出相对策略:改变农民对体育的认识;利用电视台宣传体育的功能和作用;学校体育带动农民体育,充分利用学校资源;政府做宣传,组织农民开展有特色的体育活动;开展健身会所下乡活动;大力推广广场舞的覆盖范围等,仅供同行参考。
The research work of this paper is about to analyze and dissect the reasons that why sports is un-derdeveloped in groups of farmers under the background of the current situation of rural farmers’ life by the literature method, observation method and the interview investigation method. The results of the study are that the farmers are still short of sports and the understanding of sports is still weak, which is a lagging link in the development of the national fitness. There are some relative strategies that are changing farmers’ understanding of sports, publicising the function and the role of sports by television, driving farmers sports by doing school sports and making full use of school resources, organizing farmers to develop featured sports activities by the government, carrying out the fitness center to the countryside activities, vigorously promoting square dance coverage, etc. They are only for your reference.
Superposition feedback decoding algorithm for parallel concatenated block code based on correlation operation
并行级联分组码基于相关运算的叠加反馈译码


重庆邮电大学学报(自然科学版) , 2009,
Abstract: 为了获得接近LLR算法的译码性能,对译码器的输出进行简单的相关运算,并对Chase2译码算法进行适当的改进,通过将接收信息与子译码器的输出软信息进行线性叠加反馈,实现了并行级联分组码的Turbo迭代译码.仿真研究验证了算法的有效性.
历史从来不是一个同心圆
,
- , 2016,
Abstract: 事实上,无论是在历史上还是在今天,任何一个社会共同体都同时处于两个实际存在的同心圆之中:一个是政治的同心圆,一个是文化的同心圆。政治的同心圆是指服从于同一个最高政治权力或政治权威的范围,文化同心圆是指根据同样的世界观而形成的人类生活模式的范围,在后者的表现形式中最具鲜明特征的就是关于宗教的认识。

E-Commerce Letters (ECL) , 2016, DOI: 10.12677/ECL.2016.51001
Abstract: 网络音乐出现,给音乐产业链带来了变革,然而网络音乐商业模式的缺乏却限制了网络音乐产业的发展。本文利用E3-value方法,结合产业价值链理论,通过构建网络音乐商业价值模型输入参数试算,对商业模式中各参与者之间价值的创造、交换和消耗情况进行仿真模拟,分析讨论网络音乐商业模式创新的相关策略。
The emergence of online music has brought a great change in the music industry chain, lacking of online music business model, however, the development of the online music industry has been li-mited. Combined with the industry value chain theory, this paper uses E3-value method to build an expectancy-value model of online music business model. Then this paper carried simulation anal-ysis on the creation, exchange and consumption of value of the business model participants, by inputting parameters and taking trial. And this paper analyzed the online music business model innovation correlative strategies.

Abstract: 基于切向极化薄壁压电圆管结构研制了高灵敏度水听器。依据薄膜理论,由压电圆管的几何方程、振动方程和压电方程推导出其频率方程。通过振动分析获得圆管径向和轴向谐振频率的工程设计公式,确定了薄壁圆管结构对其接收灵敏度的影响。应用有限元法完成圆管水听器的性能仿真,制作了水听器样品,测试结果与理论分析相吻合。水听器样品在测试频段内最大接收灵敏度级达-179.1 dB

Kuhn算法的单调性质

科学通报 , 1984,
Abstract: 不动点算法已经表现为非线性问题数值解的有效方法。算法的进行,常常是以某个参数(高度)的变化为标志,计算向高层发展,直至达到精度要求。有时这种发展是“迂迴”的,上升一段,又倒退一点。这种对算法效率不利的现象,在文献中称为YO-YO行为。
