When the greek ships reached the trojan land at the outbreak of the war,a prophet declared that the first greek setting foot on the enemy soil was doomed to die .protesilaus,a greek chief,seeing that there was a gooddeal of hesitation among his comrades,leapt overboard and fellinstantly,pierced through by hector''s spear .when his wife laodamia heard of this she was simply inconsolable .she offered rich sacrifice to the gods and begged zeus to restore herslaughtered lord to her.moved by her fidelity ,zeus sent hermes to escort the shade of protesilaus back to the upper air tostay with his wife for three hours.laodamia''s joy knew nobounds when she held her slain lord once more in her arms.protesilaus told her the story of his selfsacrifice,and laodamiawas happy to become a bride for a second time.however,shegave a sharp cry when she saw hermes coming at the fixed hourto take protesilaus back to the lower world.so sad was she at the second parting that she died of grief not long after.the pairwere reunited in hades.

当战争爆发时，段腊般抵达特洛伊地区。一位预言家宣称，第一个踏上敌人土地的段腊人注定会死。一位名叫普洛忒西拉斯的希腊酋长看着同伴踌躇不前，就从船上跳入水中，一瞬时他就倒下了，被海克特的长矛穿透了胸膛。他的妻子拉俄达弥亚听到这个消息，悲痛之心无法得以慰藉。她献给众神丰厚的祭品，哀求宙斯把被杀的丈夫还给她。她的忠贞感动了宙斯。宙斯派海默斯护送普洛忒西拉斯的幽魂回到阳间与他的妻子共度三个小时。她再次拥抱被杀的丈夫。她的喜悦无边无际。普洛忒西拉斯给她讲述了他自我献身的故事。拉俄达弥亚很高兴再做一次新娘。然而，当海默斯预定的时间到来时，普洛忒西拉斯将被带回阴间，她痛苦地叫了一声。对于第二次分别她如此悲痛不堪，以致于不久之后就在痛苦之中死去。他们在冥府之中再次团圆。

Now transmuted, we swiftly escape, as Nature escapes; We are Nature—long have we been absent, but now we return; We become plants, leaves, foliage, roots, bark; We are bedded in the ground—we are rocks; We are oaks—we grow in the openings side by side; We browse—we are two among the wild herds, spontaneous as any; We are two fishes swimming in the sea together; We are what the locust blossoms are—we drop scent around the lanes, mornings and evenings; We are also the coarse smut of beasts, vegetables, minerals; We are two predatory hawks—we soar above, and look down; We are two resplendent suns—we it is who balance ourselves, orbic and stellar—we are as two comets; We prowl fang'd and four-footed in the woods—we spring on prey; We are two clouds, forenoons and afternoons, driving overhead; We are seas mingling—we are two of those cheerful waves, rolling over each other, and interwetting each other; We are what the atmosphere is, transparent, receptive, pervious, impervious: We are snow, rain, cold, darkness—we are each product and influence of the globe; We have circled and circled till we have arrived home again—we two have; We have voided all but freedom, and all but our own joy.

我俩，我们被愚弄了这么久我俩，我们被愚弄了这么久，可现在变了，我们迅速逃走，像大自然一样逃走，我们就是大自然，我们离开这里已经很久，但是如今回来了，我们变成植物、树干、树叶、树根和树皮，我们被安置在地里、我们是岩石，我们是橡树，我们并排地生长在林中的空地，我们吃草，我们是野牛群中的两只，如大家一样自然，我们是在海中一起游泳的两条鱼，我们是刺槐的花朵，我们早晚在小巷周围散发香气，我们也是兽类、植物、矿物的粗劣斑点，我们是两只肉食的苍鹰，我们翱翔在高空，俯视下面，我们是两个灿烂的太阳，我们在像星球般平衡着自己，我们是两颗彗星，我们张牙舞爪地在树林巾梭巡，我们向猎物跃进，我们是午前午后在上空奔驰的两朵云，我们是交混的海洋，我们是两个欢乐的浪头，在互相浇泼和连环翻滚，我们是大气、明澈而善于接受，有时能穿透，有时不能，我们是冰雪，雨水，寒冷，黑暗，我们是地球上的每种势力和产品，我们绕了一圈又一圈，最后我们又回到家里，我俩，我们避免了—切，除了自由和我们自己的欢欣。

In the process of building and using the mass concrete structures, because of the effect of out-side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance Using nondestructive testing method to test the concrete"s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseasesThis dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic FEM to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, Researched the principles of the first-arriving waves" phase when the cracks" depths are not same, obtained the relation between the inversion point and the cracks" depth, which has the direction sense in the application of projects,The second part of this dissertation is CT , which used the ultrasonic wave running through the tested-substance to get arriving-time of the ultrasonic wave, then inverse the image This dissertation drawed one CT program which can well present the different little cells ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested-substance, CT has the better using foreground..

在混凝土结构的施工及使用过程中，由于受其自身及外界各种因素的影响，常常会产生一些缺陷，对结构物的承载能力和耐久性造成严重影响，采用无损检测技术进行质量检测和健康诊断，这对混凝土结构开展安全、稳定性评估以及病害隐患治理研究具有重要意义。本论文主要针对大体积混凝土结构缺陷的检测方法展开研究工作，重点讨论了超声波法检测混凝土结构裂缝的基本原理和方法及其特点、适用范围，运用动力有限元数值模拟其检测过程，探讨了有裂缝缺陷的混凝土结构在脉冲荷载作用下弹性波的传播及其变化特征，研究了不同裂缝深度下首波相位变化规律，得出了反转临界点与裂缝深度之间的关系，这对实际工程应用具有指导意义。声波CT是一种新的无损检测技术，它是利用声波穿透被检测体获取声波接收时间，来进行计算机反演成像的技术。本文利用直射线法编制了层析成像程序，能较好地呈现被检测物体各微小单元的声波速度分布图像，从而对检测体的质量状况作出诊断评估，具有较好的应用发展前景。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
