盗蜜贼     

连中福 《生态文化》2018,(1)

正养蜂行家都知道,对盗蜜这个词的理解一般是另一蜂种和同种蜂群进入本蜂群巢穴内抢夺和窃取本蜂群蜜液的事件。在常见蜂类种群中,中华蜜蜂相对个头小,群势弱,处于弱势状态,易受到其他种群的攻击和侵害。其天敌胡蜂就仗着个头大,体质强悍的优势,常常游戈于蜜蜂弱势群巢门前,趁守卫蜂力量薄弱,咬死卫蜂进入蜂箱内,继而咬死守脾蜜蜂,将脾上蜜和幼蜂  相似文献

友谊与团结     

H·G·伽达默尔 《安徽师范大学学报(人文社会科学版)》2002,30(5):497-501

古代的哲学家几乎没有不在其理论、演说或著作中提到"友谊"这个概念.只有了解的人才会知道,大师亚里士多德在他的三本伦理学著作中赋予友谊概念以核心的地位;而康德这位思想上值得吾人敬重的哲人,在其人类学演讲录中,却只给友谊一页的篇幅.尽管如此,他还是说出了值得我们深思的真理:"真正的朋友稀少如黑色的天鹅."  相似文献   

血尿素氮测定方法的比较研究     

朱建  金丽萍 《体育科研》1992,(1)

尿素是体内蛋白质代谢的分解产物。当剧烈运动时,体内蛋白质及氨基酸的分解代谢加强,血中尿素含量增加;身体对运动负荷的适应性是不同的,这种适应性越差,生成的尿素就越多。因此,运用这个生化指标,不仅可以评定一堂训练  相似文献   

Immediate effects of the use of modified take-off boards on the take-off motion of the long jump during training     

Koyama H  Muraki Y  Ae M 《Sports biomechanics / International Society of Biomechanics in Sports》2006,5(2):139-153

We investigated the immediate effects of the combined use of inclined and raised flat boards on the take-off motion of the long jump. Eight male long jumpers were videotaped with two high-speed video cameras (250 Hz) set perpendicular to the runway. The athletes jumped with three modified take-off boards: upward-inclined boards of two different inclinations (2.5 and 5.0 degrees), and a raised flat board (50 mm high). The jumpers performed pre- and post-jumps using their own techniques before and after use of the boards to test their effects. The post- jump revealed significantly less reduction in the horizontal velocity during the take-off than the pre-jump, and the effectiveness of converting the velocity from horizontal to vertical increased significantly in the post-jump. The post-jump demonstrated significantly less knee flexion of the take-off leg during take-off. The reduced knee flexion and slower extension velocity of the take-off leg in the second phase of the post-jump contributed to increasing the knee extension torque in the second phase and resulted in the increases in vertical ground reaction force and vertical velocity. These results suggest that the combined use of the inclined and raised flat boards induced immediate effective changes in the kinematics and kinetics of the take-off motion and represent appropriate training tools for take-off techniques of the long jump.  相似文献

The distance-time relationship over a century of running Olympic performances: A limit on the critical speed concept     

Dekerle J  Nesi X  Carter H 《Journal of sports sciences》2006,24(11):1213-1221

We analyse the evolution of the slope (critical speed) and the y-intercept (anaerobic distance capacity) of the linear distance-time relationship over a century of Olympic running performances. The distance-time relationship of each Olympic Games (1920-2004) was plotted using the performances in the 800-, 1500- and 5000-m track events. Values for critical speed and anaerobic distance capacity were determined by linear modelling. Mean performances for the 800, 1500 and 5000 m were 104.9 +/- 1.5 s (1.4%), 217.2 +/- 2.8 s (1.3%) and 808.9 +/- 18.4 s (2.3%), respectively. Critical speed improved during the first three-quarters of the twentieth century to reach a plateau in 1984. This is in accordance with the literature (Peronnet & Thibault, 1989) and suggests that "human aerobic endurance" has improved within the century (+13.4%) and tends to stabilize. Anaerobic distance capacity was highly variable over the century (coefficient of variation = 9.4%) and did not show a linear improvement over the years as has previously been suggested (Peronnet & Thibault, 1989). This could be due to an artefact in the application of the two-parameter model to only three Olympic performances. A limitation to the use of this linear mathematical model to fit physiological data may have been demonstrated.  相似文献
