The result proved that the ATMD which was designed rationally can availably reduce the Wind-Induced Vibration of structure.

数值结果表明，进行合理化设计的ATMD能够有效地抑制结构的风致振动。

Blue brougham drawn by two magnificent bays, and I remembered having also remarked in her at that time an air of distinction rare in women of her kind and which was further enhanced by her truly exceptional beauty.

她身上有一种不同于她那一类人的气质，而她那风致韵绝的姿色，又更衬托出了这种气质的与众不同。

My only tactical error on the day was to choose Wembley Stadium station over Wembley Park for my get-away,thus condemning myself to along spell in the Disneyland-style queuing system devised for us by Chiltern Railways.

那天我唯一的战术失误是解脱时选择了温布利球场站而不是温布利公园站，完结就处罚了我自己要置身于由奇尔特恩铁路公司为我们计划的那个有迪斯尼乐园风致的排队制度里一段永劫间。

A time-frequency analysis method based on HOS is proposed to study the girder gust response, and the supreme mode contributed to gust response and the modal coupling could be identified using this method.

二、提出利用基于高阶谱的时频分析研究大桥非平稳、非线性风致振动响应，能够得出对不同测点风致振动响应贡献最大的模态和耦合振动模态。

At home,on any early autumnmorning,many countryfolk would pass my door:the men with bronzedal'nls and protruding calf muscles,their bodies tall and uptight,evok-ing a sense of well-being;the women,usually with white turbans dot.ted with dark flowers,go barefoot and wear short coarse linen skirts,and while they ale not as tall as the men,they still have their ownbrand of healthy beauty.Each carries a shoulderpole with bundles fullof long,fresh and tender sections of lotus root the coour of whitejade.

若在故乡，每当新秋的早晨，门前经过许多乡人：男的紫赤的胳膊和小腿肌肉突起，躯干高大且挺直，使人起健康的感觉；女的往往裹着白地青花的头巾，虽然赤脚，却穿短短的夏布裙，躯干固然不及男的那样高，但是别有一种健康的美的风致；他们各挑着一副担子，盛着鲜嫩的玉色的长节的藕。

The background component must be calculated by integration of the product of aerodynamic force covariance and influence function, instead of mode superimposition, while the resonant component only consider the contribution of the 1st mode.

前者不能按振型分解法求解，而应通过对气动力协方差与影响函数乘积积分的方法来计算；后者可只考虑一阶振型的贡献，两者应按平方和开方的原则组合得到脉动风致响应的峰值。

In the second part of the work here, wind-induced snow pressure of membrane structures is studied.

论文的第二部分对膜结构的风致雪压进行了研究。

In this paper, the wind tunnel test of large span roof structures' dynamic wind loads have been discussed systematically, the modal decomposition method and time domain method, which was combined with the result to calculate the wind-induced vibration responses and equivalent static wind loads of (non-large-deformation) large span roof structures are also studied at the same time, and some engineering-valuable conclusions are summarized.

本文正是在这种背景下，依托武汉体育中心游泳馆屋盖的风洞试验研究，对现有的大跨屋盖结构的风荷载及风致响应计算方法做了一定的改进，在风致响应理论在实际工程中的应用上得到了一些有工程价值的结论。

The round cross-section rods in quayside container crane are very easy to induce wind resonance,and the main form of the rod wind vibration is crosswind vibration,especially the vortex vibration.

岸边起重机川的圆截面杆件容易发生风致振动，风致振动山的主要表现形式为横风向的振动，其中以涡激振动为主。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
