The Yutian earthquake with M_S7.3 happened on February 12,2014. The precursor monitoring ability is weak in that area. We found tendency anomalies and middle- and short-term anomalies from metal pendulum tilt measurements in Hotan seismic station before the earthquake. And we also compared the anomalies with that of the M_S7.3 Yutian earthquake on March 21,2008. The tendency anomalies measured by the metal pendulum tiltmeter appeared since 2012 as tilting eastward. While the middle- and short-term anomalies were characterized by acceleration,pause and rapid change of tilt rate in two directions. The tendency anomalies of metal pendulum tilt records are the same before the two earthquakes. They both happened in the east direction. However,there are differences in duration,characteristic and earthquake intervals for the middle- and short-term anomalies. The founding anomaly is weak in that area.

The tendency anomalies of metal pendulum tilt records are the same before the two earthquakes. However, there are differences in duration, characteristic and earthquake intervals for the middle - and short-term anomalies.

摘 要: 习语是英语词汇的一个组成部分,言简意赅,寓意深刻,形象生动,是重要的修辞手段,是英语语言的精华与核心,是民族文化的结晶,反映出人民的智慧。运动与民族文化紧密相连,作为社会文化生活的一面镜子的运动习语,就必然会反映出这方面的内容。本文通过对源于赛马运动的常用英语习语的分析,探究运动习语的文化内涵和隐喻性,旨在引起人们对运动习语的认识,从而强化其在日常生活中的理解和运用。  关键词: 习语
摘 要:《约伯记》被称为《圣经》中最庄严和高贵的作品。因为上帝对约伯无端的审判,使《圣经》中整个神性的价值观在约伯心中发生了一次危机,成为探讨西方文明中人自身价值不可不深思的故事。本文即以人自身的价值为基点,探讨人的价值如何在上帝的秩序中得到肯定与追求。  关键词:约伯记;上帝;秩序;人的价值  《约伯记》以散文和诗歌的形式,戏剧化地记述了义人约伯无辜受难的故事。约伯是一个完全的正直的人,敬畏上帝
