Books are partners of thoughts, but you should take along your books on trains, to your logdings, not when you ' re strolling on your own, which great, deep, encouraging, clear and beautiful thought can ' t find its root in the wind, among the clouds, along the up - and - downs of the hills, and within the color and fragrance of the flower and the grass
書是理想的伴侶，但你應得帶書，是在火車上，在你住處的客室里，不是在你獨身漫步的時候，什麼偉大的深沉的鼓舞的清明的優美的思想的根源不是可以在風籟中，雲彩里山勢與地形的起伏里，花草的顏色與香息里尋得？ -
Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world
主要對濃縮風能型風力發電機在正常運轉時，噪聲產生的機理進行了理論分析研究，並與普通型風力發電機的噪聲進行了對比實驗分析；利用現代聲學測試手段對兩類機型進行測試與分析，得出濃縮風能型風力發電機產生噪聲低於普通型風力發電機和葉輪是風力發電機產生噪聲的主要部件的結論；通過對兩類機型的噪聲、輸出功率的測試，得出隨著風速的增加，兩類風力發電機的輸出功率在增加，產生的噪聲也在增加的結論；提出了進一步降低濃縮風能型風力發電機噪聲的措施，從主動降噪方面，研製低額定轉速的發電機；從被動降噪方面，採用微孔穿板的降噪結構；為研究開發一種國際上低噪聲、高水平的風力發電機打下了良好的技術基礎。 -
Instances become members of other instances, and eventually you wind up with a root object instance that, along with its attributes, has various methods for manipulating data in ways that cannot break the validity requirements in contrast to how easily one can break validity with basic types like strings and arrays
實例成為其它實例的成員，最終您得到一個根對象實例，該實例與其屬性一起，具有以不能破壞有效性要求的方式操縱數據的多種方法（與之相反，使用象字元串和數組那樣的基本類型很容易破壞有效性） 。 -
Finally, the average value, root - mean - square value, maximum, minimum, spike factor of wind force, wind force moment are analyzed to studied the mutually interference influences to the base force of high buildings and group of buildings
最後分析不同狀態下風力、風力矩的平均值、均方根值、最大值、最小值和峰值因子，探討了風荷載下高層建築的相互干擾和群樓對建築物風力影響。
