急剧的

The results show that side force, lift and overturning moment obtained by simulation and by wind tunnel test are consistent. When train travels with certain speed, the aerodynamic force and overturning moment acting on passenger car running on bridge, embankment and flat will increase greatly as cross-wind becomes larger while those increase less when the train runs on cut. Under the condition of strong cross-wind, aerodynamic force and overturning moment acting on train traveling on bridge are the largest. So the train traveling on bridge tends to overturn compared with that traveling on other three kinds of railway conditions. Aerodynamic force and moment acting on train traveling on cut are the least.

研究结果表明：侧向力、升力和倾覆力矩数值模拟结果与风洞实验结果均吻合较好；车速一定时，随着侧风速度的增大，列车在桥梁、路堤、平地上运行所受气动力和倾覆力矩均急剧增加，而在路堑上运行所受气动力及力矩增加缓慢；当侧风速度一定的情况下，客车在高桥上运行所受到的气动力及力矩最大，因此，强侧风下列车在高桥上运行较容易发生倾覆事故；在路堑上所受到的气动力相对最小。

The generation of blue light through direct frequency doubling of 860nm has been achieved in our two typical samples. Sample A and sample B have the number of domain laminas of 460 and 290 respectively, and the SHG efficiency are 4.2% and 3.5% in the two samples.

通过在不同的晶体偏角下进行基波波长扫描的倍频效率的测量，给出光学超晶格样品的&允许偏角&，超过这个角度，非线性倍频转换效率急剧下降。

Last week the Minneapolis Federal Reserve Bank produced data calling into question some of the key claims of the financial crisis alarmists, particularly that bank lending to nonfinancial corporations and individual borrowers has declined sharply and that interbank lending is essentially nonexistent.

上周明尼阿波利斯联邦储备银行把数据调用发法引入到对金融危机的杞人忧天者的关键主张所进行的询问上，尤其是针对那些贷款给非金融团体而个人贷款者急剧下降以及实质上不存在相互间拆借的银行。

Though the proportion of city-dwellers has soared, they are different from the atomised individualists of Europe or North America: the extended family and traditional social networks have survived even in teeming Tehran.

虽然城市居民的比例急剧增加，但这些居民和欧洲以及北美的分化的个人主义者不同：即使在开放的德黑兰，大家庭和传统社会关系依然存在。

With the constant development of economy, the various forms of meeting attendees increased dramatically, all kinds of information also rise.

The mini-boom in bookings has come during what is traditionally the slowest time of year for aircraft charterers.

自上周四航空公司出现恐怖警告之后，因富有的旅行者试图避开拥挤不堪的机场以及严格的安检限制，市场对公务包机的需求急剧上升。

There have been no noticeable adverse effects of the dollar's decline on the US economy: inflation is nowhere to be seen (and indeed deflation is the greater risk), interest rates are at fifty-year lows and the equity markets have recently surged.

而美元的贬值并不会对美国经济带来明显的消极影响：通货膨胀无处可见（而实际上，通货紧缩的风险更大），国内利率处于50年以来的最低水平，而股票市场最近急剧上扬。

During a meeting in Montreal last week, these researchers indicated that the disappearance of permafrost, similar to the melting of ice floes, is rapidly changing the lifestyle of local residents

In Scandinavia, the Elder Futhark remained in use until some time around the eighth century, when drastic changes in the Old Norse language occurred, and corresponding changes in the runic alphabet were made to accommodate the new sounds.

在斯堪的纳维亚，老Futhark仍然使用，直至一些公元8世纪左右的时间，当在古诺尔斯语发生了急剧变化，在卢恩字母了以适应新的声音相应的变化。

The modern china of hundred-year were the greatly turbulent time, the revolution became main melody of this time, the china revolution history naturally have also become the core for historical research, this will cause the china history narrative pattern to transform inevitably.

近代中国百年是急剧变革的大动荡时期，革命构成了这一时期历史的主旋律，中国革命史也就理所当然成为历史研究关注的核心，这势必导致中国历史叙事范式的变革。
