So on behalf of America, Russia, and everyone else in the 21st century, let me say how impressively cute we find this development, and look forward to a future where the yellow man remains on the cutting edge – rolling out such modern technological marvels as the steam engine, hoola hoop, and ham radio vacuum tube.

所以，作为美国、俄罗斯以及处于21世纪的其他人的代表，让我说明我们发现这一进步是多么印象深刻地有趣，期盼一个黄种人仍然处于危机边缘的未来------晃动着现代科技奇迹例如蒸汽机、呼拉圈、业余无线电的真空管。

After researching the proplems above, the standard and systematic theory on erection of hauling system of suspension bridge is formed ,and by application in erection of RengYang bridge "which is domestic first, the third in the world", main cable wire strand was kept well in the erection, record which is,the most quik ever in china or in the world and which can erect eight main cable wire strands in a day was even finished, it guaranteed the high—quality and high—efficient hauling erection in wire strand of RenYang bridge.

经过以上几个方面的研究，初步形成了一套规范化、系统化的悬索桥主缆索股牵引技术研究理论，通过在&中国第一、世界第三&的润扬大桥主缆施工过程中的具体应用，索股形状保持较好，有效地控制了索股乱丝、呼拉圈、扭转等现象的发生，曾实现一天架设8根(单边4根)的国内外最快施工记录，确保了大桥主缆索股优质高效的牵引施工。
