You are a cursed emigrant , cried a farrier , making at him in a furious manner through the press , hammer in hand ; and you are a cursed aristocrat “你是个该死的外逃分子， ”一个钉马掌工人手拿郎头暴跳加雷地穿过人群向他奔来， “你还是个该死的贵族分子！ ”
The present development and application of electro - hydraulic hammer in china have been introduced by quotation of such abroad and the future prospect in china has been expected properly 摘要通过对国外电液锤技术的引述，介绍了目前国内电液锤技术的发展与应用状况，并展望了电液锤发展前景。
Find out the reason that affects the impulse press . first research the water hammer in the hydraulic impulse testing machine , find out the rules of the instantaneous flow and press 首先对液压脉冲试验台的压力冲击?水锤( waterhammer )进行探讨，了解管道系统压力冲击过程中瞬态流量和压力的变化规律。
My dad did . armand hammer came . and the meeting took place . that was the beginning of incredible and impossible accomplishments armand hammer did for this ministry . i remember one lunch with armand hammer in my father s office 我还记著在十二楼我爸爸的办公室吃午餐，当时大约有六七人跟阿曼德一起，他说在数星期前曾跟哥巴卓夫见面。
Based on physical experiments , establishing mathematical model , carrying on theoretical calculations , and contrasting experimental results with theoretical ones , it turned out that under the same initiate flow rate , the quicker the closing of the ball valve , the longer the stable time when the liquid gets to vaporizing pressure , and the bigger the water hammer in water interception collision ; under the same closing velocities of the ball valve , the larger the initiate flow rate , the longer the stable time when the liquid gets to vaporizing preesure , and the bigger the water hammer in water interception collision 在试验研究的基础上，建立了含气水锤数学模型，进行数值计算，并与试验结果进行了比较，结果表明，在管道初始流量相同的情况下，球阀关闭速度越快，液体达到汽化压力凡时稳定的时间越长，弥合水锤压力也越大;在球阀关闭速度相同的情况下，管道初始流量越大，液体达到汽化压力凡时稳定的时间越长，弥合水锤压力也越大。
Cave began to hammer in the former qin dynasty jianyuan 2002 ( year 1366 ) , amended after the generation of this 492 caves exist . 45 , 000 square meters of colorful murals , sculptures 2415 president , is now the largest treasure trove of grotto art . one of the most abundant elements . 1987 was listed by unesco as world cultural heritage 洞窟始凿于前秦建元二年(公元366年) ，后经历代增修，今存洞窟492个，壁画45000平方米彩塑雕像2415尊，是我国现存石窟艺术宝库中规模最大、内容最丰富的一座。
The assisting mechanism of hammer in dredge haul is to accumulate energy with wire pull , draw inner pole firstly , release by pin framework , acceleratc core piece , strike hammer shell , produce great instantaneous wallop , drag dredge to break op stone immediately , restore with reposition spring , and work again finally 该机构在拖网取样时利用钢缆拉力蓄积能量拉动内部拉杆，并通过销轴机构释放能量加速冲击芯块，撞击壳体产生巨大的瞬时冲击力，拽动拖网破碎岩石，然后使用复位弹簧使机构复位，重新工作。
The mousetrap must contain a solid base to attach the four other parts to , a hammer that clamps down on the mouse , a spring which gives the hammer the necessary power , a holding bar which holds the now energized hammer in position , and a catch to which the holding bar is secured , holding the hammer in coiled tension 一个捕鼠器必须有一个坚固的底部，用来安装其余四个零件，包括一个击打老鼠的锤子，一个给锤子足够力度的弹簧，一支用来承托上了弹簧的锤子的竿，和一个用来稳定这支竿的把手，使得锤子稳定在弹簧的拉力下。
The local directional drilling is just staring in terrane , the equipments and the technologies ca n ' t satisfy far and far the spot construction needs , according to current circumstance and considing the existed equipments , the author put forward drilling by air hammer in terrane , having designed compounded - drilling tools , and recommended technology parameters . producing experiments have obtained good achievements in economic and in techniques 国内定向钻进铺管技术在岩层只是刚刚起步，设备、工艺远远不能满足现场施工需要，本文针对国内、外岩层定向钻进非开挖设备及工艺现状，结合国内大多施工单位的已有设备，提出岩层空气潜孔锤导向钻进工法，设计了适合岩层钻进的实用钻具，并提出具有针对性的工艺参数，生产性试验取得了良好的经济技术指标。
