As a national nature reserve established in minority area, Dafengding nature reserve in Mabian, Sichuan province, has some problems of reserve management and its surrounding communities social economy.

马边大风顶自然保护区作为一个设立在少数民族地区的国家级自然保护区，自建立以来，就在保护区管理工作、保护区与社区社会经济方面存在着一些问题。

The main factor which influences the heat exchange performance of air cooled condenser is the backflow or recirculation of hot air caused by the environmental big wind.

摘 要：影响空冷凝汽器换热性能的主要因素是环境大风所造成的热风回流或热风再循环。

In the early 1920s, David Grandison Fairchild (1869–1954) of the Office of Foreign Seed and Plant Introduction, Bureau of Plant Industry, United States Department of Agriculture sent Rock, who was then in charge of the herbarium at the College, in search of the oily seeds of the East Indian chaulmoogra tree.

1910年左右，洛克的研究开始转向夏威夷学院有关大风子树油的方向，大风子树油曾被用来治疗麻风病。1920年初，时任学院植物标本管理员的洛克，受到美国农业部植物局David Grandison Fairchild (1869–1954)的派遣，前往东印度寻找大风子树富含油脂的树种。

Yesterday, a strong cold air by the impact of strong winds occurred in Shanxi most cool weather, Ningwu, Binh Dinh, Fenyang, Awayama, Yangquan and other 45 counties and cities in the instantaneous wind up to 7 or above, which Jincheng 13:16, Wutai 14:29 and 20:05 appear instantaneous 10 westerly or northwesterly winds.

昨天，受较强冷空气影响，山西大部出现大风降温天气，宁武、平定、汾阳、稷山、阳泉等45个县市瞬时风力达7级或以上，其中，晋城13时16分、五台山14时29分和20时05分出现瞬时10级西风或西北大风。

We wanted to find out exactly how windy Wellington is and when it is windy.

我们要找出到底是当有大风惠灵顿大风。

Careful analysis on NBE can facilitate nowcasting of severe weather events and further understanding of their evolution. After detailed study on three cases concerning with NBE, it is concluded:(1) NBE triggered by fast moving echo in upstream is an important indication of disastrous wind;(2) NBE can develop into severe storm under proper conditions. There are often two stages during this kind of growing: the first is developing of initial echo, the second is snap growing of echo core;(3) Doppler radar reflects outflow of downburst as a nearly ringed NBE. Inside look on downburst can be obtained combining NBE with other data.

文章结合发生在上海的3次强对流天气个例，详细分析了弱窄带回波在分析和预报强对流天气中的作用，得出以下结论：（1）上游移动强回波的出流边界导致的弱窄带回波是大风预警的重要判断参考；（2）在合适的层结状态和抬升条件下，弱窄带回波会强烈发展，并导致局地雷雨大风，这类强对流天气的发展有两个比较重要的阶段：弱窄带回波上初始回波的发展和回波跃增；（3）下击暴流造成的地面出流在雷达回波上表现为近似圆弧的弱窄带回波，这种弱窄带回波与其他雷达观测特征以及地面观测相结合，有助于对产生下击暴流的对流云的发生发展过程进行细致分析。

A wind changes big gradually, from the beginning breeze turns the gale, also turns the strong wind from the gale, the final strong wind becomes the hurricane, and the storm finally arrives.

风一点点变大，从开始的微风变成大风，又从大风变成了狂风，最后狂风成了飓风，风暴终于来临了。

For a long time, people have emphasized statistical analyses of data and diagnostic study of dynamical mechanisms for high wind events in order to find their disciplinarians, and great progress has been made, but the numerical simulation study of high wind events in the areas is still a few.

长期以来，人们着重于对渤海和北黄海大风的各种资料进行统计分析，并对其发生发展的动力学特性进行诊断研究，从而发现其内在规律，并取得了重要的进展，但是对渤海和北黄海大风的数值研究却十分缺乏。

The results indicate that MM5 has effect on predicting the strong clear-air turbulence, but no effect on predicting the thunder storm. The beginning and ending time, strength variation tendency and wind direction of the strong clear-air turbulence can be forecasted well by mesoscale model.

结果表明，中尺度模式对雷雨大风基本无预报能力，但对晴空系统性大风有很强的预报能力，模式可以对晴空系统性大风的出现时间、强度变化趋势和风向提供较准确的预报，对晴空系统性大风的结束时间也有一定的预报能力。

On a 刮大风的 March morning when my children were young, I took them down to an open field to fly a kite I had 制作 pine sticks, butcher paper and glue.

我的孩子们都还很小的时候，一个三月的早晨，刮着大风，我带他们到一片开阔地去放风筝。风筝是我用松树枝条、包肉纸和胶水做的。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
