张东翰 《商洛学院学报》2014,(6):8-9

通过分析图Dn,4的结构,利用穷举法和组合分析法讨论了图Dn,4的邻点强可区别的全染色,通过构造具体染色得到了图Dn,4的邻点强可区别的全色数。从而证明了图Dn,4的邻点强可区别的全色数是存在的。  相似文献   

论新时期用尽当地救济原则的适用     

潘峰 《齐齐哈尔师范高等专科学校学报》2014,(4):109-111

在国际投资领域,用尽当地救济是处理东道国与外国投资者之间纠纷的一项传统而重要的国际法原则。但是,出于维护自身财产权利的考虑,和对东道国司法的不信任,越来越多的外国投资者倾向于将投资争议诉诸国际投资争端解决中心来予以解决。这种做法导导致了ICSID仲裁庭管辖权的扩大,甚至凌驾于东道国国内司法体系之上。而对于东道国,特别是广大发展中国家来说,是十分不利的。因此,如何正确地适用＂用尽当地救济＂原则来保护国家利益,是值得我们研究的。  相似文献   

Different durations within the method of best practice affect the parameters of the speed–duration relationship

The aim of the study was to determine whether estimates of the speed–duration relationship are affected using different time-trial (TT) field-based testing protocols, where exhaustive times were located within the generally recommended durations of 2–15?min. Ten triathletes (mean?±?SD age: 31.0?±?5.7?years; height: 1.81?±?0.05?m; body mass: 76.5?±?6.8?kg) performed two randomly assigned field tests to determine critical speed (CS) and the total distance covered above CS (D?). CS and D? were obtained using two different protocols comprising three TT that were interspersed by 60?min passive rest. The TTs were 12, 7, and 3?min in Protocol I and 10, 5, and 2?min in Protocol II. A linear relationship of speed vs. the inverse of time (s?=?D??×?1/t?+?CS) was used to determine parameter estimates. Significant differences were found for CS (p?=?0.026), but not for D? (p?=?0.123). The effect size for CS (d?=?0.305) was considered small, while that for D? was considered moderate (d?=?0.742). CS was significantly correlated between protocols (r?=?0.934; p?D? (r?=?0.053; p?=?0.884). The 95% limits of agreement were ±0.28m?s^?1 and ±73.9?m for CS and D?, respectively. These findings demonstrate that the choice of exhaustive times within commonly accepted durations results in different estimates of CS and D?, and thus protocols cannot be used interchangeably. The use of a consistent protocol is therefore recommended, when investigating or monitoring the speed–duration relationship estimates in well-trained athletes.  相似文献   

论权利穷竭原则的本质——“知识产品权利分离说”之提出与解读     

刁胜先 《科技管理研究》2017,(2)

世界知识产品贸易中各国政策的冲突与知识产权立法的分歧,使权利穷竭这个陈旧的话题不断引起学界新的关注且众说纷纭。究其根源,在于权利穷竭的法理本质并未得到应有重视与必要统一。因此,有必要从回归知识产权的视角,在对权利穷竭的相关理论学说评析基础上,审视权利的初始分配正义,直面"权利穷竭"命题的局限,尝试提出"权利分离说",将知识产品上的知识产权、物权乃至于其他财产权同等重视,在客体、内容与效力等方面将其互相分离,以寻求同一财产对象上不同权利间和谐公平的共生共存之秩序,从而将"权利分离原则"上升为财产权法的共有原则。  相似文献   

大鼠力竭性运动后心肌和骨骼肌线粒体膜脂质过氧化水平变化   总被引：4，自引：0，他引：4  

张勇  陈家琦  李玉琳 《天津体育学院学报》1994,9(1):57-64

本文旨在探讨递增负荷力竭性运动对大鼠心肌和骨骼肌线粒体膜脂质过氧化（ＬＰＯ）水平的影响。采用三级递增负荷跑台跑运动至力竭为运动模型，分别测定运动后即刻大鼠心肌和骨骼肌线粒体丙二醛（ＭＤＡ）含量。发现心肌线粒体ＬＰＯ水平显著性增高（Ｐ＜０．０５）；骨骼肌线粒体ＬＰＯ水平增高，但无显著性（Ｐ＞０．０５）。同时测定心肌和骨骼肌组织ＭＤＡ，也观察到相同的变化规律。提示，递增负荷力竭性运动对心肌和骨骼肌线粒体膜ＬＰＯ水平具有不同程度的影响，可能与运动中心肌和骨骼肌不同代谢应激有关；ＬＰＯ水平增高，将影响线粒体呼吸链氧化磷酸化及ＡＴＰ生成，可能是运动性疲劳的重要膜分子机制之一。  相似文献
