跨文化交际与词语的文化涵义翻译

Language and culture are closely related to each other. This paper studies the principles and approaches of translatingculture-loaded words in the context of cross-cultural communication by exploring the relation between culture and transla-tion. Culture-loaded words are considered difficult to translate because these words contain cultural connotations and obviouslymirror cultural characteristics. In light of cross-cultural communication research, the paper proposes that in translation of cul-ture-loaded words semantic and pragmatic equivalence should be achieved by adopting proper translating methods.

T形配钢型钢混凝土偏压构件力学性能研究

建立了T形配钢型钢混凝土偏压构件力学性能分析的有限元模型,计算结果得到以往实验结果的验证。在此基础上,分析了不同阶段材料应力状态和各参数对偏压构件力学性能的影响。结果表明:T形配钢型钢混凝土构件在不同加载角下的性能有所不同,加载角为180°时极限承载力大于其他角度情况;混凝土抗压强度、型钢含钢率、配筋率、荷载偏心率、长细比对构件荷载-变形曲线的影响较大,随着混凝土强度、型钢含钢率、配筋率的增加,极限承载力和刚度增加;随着荷载偏心率的增加,极限承载力和刚度下降;随着构件长细比的增加,构件承载力总体呈现线性下降趋势,刚度下降明显。     

沙滩排球训练对女排运动员弹跳力动力学指标影响的比较研究

1998年的沙滩排球训练周期前后,对我国12名兼职沙滩女排运动员的弹跳力进行了动力学测试。结果表明,训练后硬地原地纵跳的弹跳时间比训练前显性延长,训练后纵跳高度及与纵跳高度相关较密切的动力学指标较训练前都有统计学意义上的提高,表明沙地训练对提高硬地弹跳力具有积极作用。     

Kinematic and kinetic analysis of the goalkeeper’s diving save in football

Kinetics and full body kinematics were measured in ten elite goalkeepers diving to save high and low balls at both sides of the goal, aiming to investigate their starting position, linear and angular momentum, and legs' contribution to end-performance. Our results showed that goalkeepers adopted a starting position with a stance width of 33 ± 1% of leg length, knee flexion angle of 62 ± 18° and hip flexion angle of 63 ± 18°. The contralateral leg contributed more than the ipsilateral leg to COM velocity (p < 0.01), both for the horizontal (2.7 ± 0.1 m·s^?1 versus 1.2 ± 0.1 m·s^?1) and for the vertical component (3.1 ± 0.3 m·s^?1 versus 0.4 ± 0.2 m·s^?1). Peak horizontal and peak angular momenta were significantly larger (p < 0.01) for low dives than for high dives with a mean difference of 55 kg·m·s^?1 and 9 kg·m²·s^?1, respectively. In addition, peak vertical momentum was significantly larger (p < 0.01) for high dives with a mean difference between dive heights of 113 kg·m·s^?1. Coaches need to highlight horizontal lateral skills and exercises (e.g. sideward push-off, sideward jumps), with emphasis on pushing-off with the contralateral leg, when training and assessing goalkeeper’s physical performance.
