In accordance with the principle of sport biomechanics, the classification of power in Chinese wushu is discussed, the differences between power and jin are differentiated and the essence of jin is probed into.
本文运用运动生物力学原理,分析了武术运动中力的分类、力与劲的区别和劲的力学本质,探讨了在武术运动中,如何把人体内蕴之力,也即劲,合理有效地化为外力发放出来,并验证了古代拳论的科学性,为武术训练提供了现代力学的理论依据。
Effects of K_2CO_3 on Cigarette Tar,Nicotine,Free Nicotine,pH Value,and Impact;
碳酸钾对卷烟主流烟气焦油、烟碱、游离烟碱、pH值及劲头的影响
To analyze the effect of potassium carbonate on cigarette impact and its reason,this paper studied how potassium carbonate affected the free nicotine in TPM and the pH in cigarette mainstream smoke.
为了分析碳酸钾影响卷烟劲头的原因,作者研究了碳酸钾对卷烟总粒相物游离烟碱、主流烟气pH值的影响,结果表明:碳酸钾使卷烟主流烟气pH值增加,提高了主流烟气中游离烟碱的转化率,导致卷烟劲头增加。
A proposal was put forward that such indices as dynamic stability,relative deformation,static creep stiffness and dynamic creep stiffness should be used to make a multi-indices evaluation of high temperature performance.
通过室内车辙试验以及静态蠕变、动态蠕变试验,研究了混合料在特定温度和压力等条件下的变形特性,全面考察了沥青混合料的高温性能,提出宜采用车辙动稳定度、相对变形、静态蠕变劲度和动态蠕变劲度等指标对混合料高温性能进行多指标综合评价;相关分析表明,不同厚度试件(50,70 mm)的车辙动稳定度以及相对变形均表现出较好的线性相关性,试验温度40℃的条件下的静态蠕变劲度和动态蠕变劲度之间也表现出较好的线性关系。
