Based on local coupling mode theory of graded index optic fiber wave guide, the variation regularity of coupling output light has been deduced when sound wave acts on single mode optic fiber coupler. and a new idea has been proposed that a novel sensor can be applied on detection of acoustic / vibration. the sensing element of sensor is the melting area of single mode coupler in which the feasibility of the new - type optic fiber sensor has been proved in experiment
本文從緩變光纖波導的局部耦合模理論出發，推導出了單模光纖耦合器耦合分光在聲波作用下的變化規律，提出了以單模光纖耦合器的熔融區為傳感元件的傳感器在聲振動信號檢測中應用的新思想，並實驗論證了這種新型光纖傳感器應用於實際的可行性。 -
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
