查询词典 in the wind

Through comparing and analyzing the wind speed in and out the slope,we find that natural wind has effect to the wind in riprap slope, both of which have uniform change trend, and with the distance from the inside of the riprap slope and block stone to the slope surface getting bigger, the natural wind effect gets lessening.

The wind power industry is growing rapidly it has increased 23 to 30 percents in each of the last 5 years , wind power is clean, abundant , ever renewable , and free from producer boycotts or embargoes, R is the executive Director of the America wind association, today only 1 percent of US 's energy comes from wind , it provide more than 20 percents of Denmark energy , the US hope to match that in twenty years .

风能产业发展很快，在过去的5年中每年都以23-30%的速度增加，风能是清洁，可再生，也不会遭到生产者的抵制禁用。R是美国风能协会的执行主管，他说美国的能源只有1%来自风能，却提供了丹麦20%多的能源，希望美国能在20年内达到这种水平，，但是现在又很多困难使风能替代石油的地位。

The growth relationship between spectrum parameter and fetch were studied, from which three parameters and overshot phenomenon that appears during wind wave spectra developing were tested, and an equation describing the growth of three-parameter spectra with wind wave was obtained With the equation, the spectra of wind waves were obtained at zero-dimensional fetches of 300, 500, 2000, 5500, 10000, and 15000, and the overshot was described more clearly. However, the overshot does not exist in the whole process of wind wave spectrum development as stated previously by Hasselmann, but in the early stage of the development only, extenuates with wave growth and then disappears when the wave fully grows.

基于已得到的谱参量随风区的变化关系，对三参量风浪频谱以及风浪频谱成长过程中存在的&超射&现象作深入的研究，得到三参量风浪频谱随风区的成长关系：在此基础上，得到无因次风区：300、500、2000、5500、10000、15000下，风浪频谱的谱线，从而直观地描述了风浪频谱成长过程中的&超射&现象，并认为在风浪频谱的成长过程中确实存在着&超射&现象，但是该现象并不如Hasselmann等提出的理论中阐述的那样存在于风浪频谱成长的全过程，而是仅存在于风浪频谱成长的初期。
