Cbb20适用于电子设备尤其是音响设备中的容量稳定性、损耗、绝缘电阻要求高的交直流电路中。 - 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
主要对浓缩风能型风力发电机在正常运转时，噪声产生的机理进行了理论分析研究，并与普通型风力发电机的噪声进行了对比实验分析；利用现代声学测试手段对两类机型进行测试与分析，得出浓缩风能型风力发电机产生噪声低于普通型风力发电机和叶轮是风力发电机产生噪声的主要部件的结论；通过对两类机型的噪声、输出功率的测试，得出随着风速的增加，两类风力发电机的输出功率在增加，产生的噪声也在增加的结论；提出了进一步降低浓缩风能型风力发电机噪声的措施，从主动降噪方面，研制低额定转速的发电机；从被动降噪方面，采用微孔穿板的降噪结构；为研究开发一种国际上低噪声、高水平的风力发电机打下了良好的技术基础。 - With the development of economics and the consequent improvement of the living standards of people , it has become one of the inevitable objects in the research of residence design to meet the need of appreciating music , digital video disk ( dvd ) , and other household visual - acoustic apparatus more comfortably and effectively in the living room
随着经济发展，人民生活水平的提高，满足在起居室内高质量地欣赏音乐、数码影片（ dvd ）等的要求，已成为住宅设计发展的一个必然的课题。西方国家在80年代就进行了类似的研究，在我国还未见相关的报道。
