功率降低 meaning in English
decay of power
power decrease
Examples
- The total sound radiation power can be reduced by counteracting the adjoint coefficients of sound radiation modes of the first n radiation modes
声辐射模态伴随系数与对应的辐射声功率成正比。通过抵消前n阶声辐射模态伴随系数，就可以使总声功率降低。 - People are interested in the study of asac system based on the radiation modes of radiation structure in recent years , and the system can reduce sound radiation power by controlling radiation modes
其中以声辐射模态为基础的asac系统是近年来的研究热点。这种方法是通过声辐射模态的抑制来使结构的辐射声功率降低。 - Liuzzi struggled as he had in qualifying with a braking problem and a down - on - power engine , stayed ahead of coulthard throughout , but then had to pit on the penultimate lap with a hydraulic problem in the steering
里尤兹则因为同排位赛的刹车问题和功率降低了的引擎而苦苦挣扎，不过整场比赛中却一直排在库塔之前，但就在倒数第二圈的时候由于转向液压故障而不同不再次停站。 - But to circular plate with large surface area , the vibrate modes generated is often so high that there is reverse phases existing , which result in a decrease in radiation impedance , electric - acoustic efficiency and the electric power , as well as poor directivity
然而对于辐射面积较大的弯曲振动圆盘，一般激励的振动阶数比较高，因此存在弯曲振动的反相区，导致换能器的辐射阻抗下降，电声效率和声功率降低以及指向性变差等问题。 - A collinear acoustooptic - deflector of pronton - exchanged linbo3 channel wave - guide is studied . the theoretical analysis , structure design and device fabrication of linbo3 pronton - exchanged acoustooptic wave - guided deflector have been finished in this thesis . the width of wave - guide , the width , spacing , effective aperture and width of electrode of interdigital transduces have been theoretically analyzed and designed
本论文研究了一种质子交换linbo3沟道波导共线式声光偏转器,其特点是利用了沟道波导的横向约束,限制了声波的发散和衍射效应,使得窄孔径电极结构得以实现,从而增加了功率密度,使总的声场驱动功率降低。
