noise radiation meaning in Chinese
噪声辐射
Examples
- On the basis of the theory of vehicle - track coupling dynamics and noise radiation and propagation , mechanism of wheel / rail noise is analyzed
根据车辆轨道耦合动力学理论及声辐射与传播理论，分析了列车运行过程中产生轮轨噪声的机理。 - The results show that the main noise source is the fuel cell auxiliary system while roof panel and rear quarter panel are the key parts contributing to noise radiation
其总布置和噪声源有别于传统汽车，为了提高乘坐舒适性，很有必要研究其振动噪声特性。 - The dgeu noise is made up of multiple sound sources . in light of the noise radiation mode , it can be classified into the aerodynamic noise and the surface radiation noise
柴油机噪声是一个由多种声源构成的复杂声源，按照噪声辐射方式，柴油机噪声可以分为空气动力噪声和表面辐射噪声。 - Secondly , research development of noise control is analyzed and theory research of noise radiation , noise measurement and noise resource diagnosis , cae , research of numerical value and visual analysis , noise active control are described in this paper
接着，分析噪声控制工程的研究进展，提出噪声辐射理论研究，噪声测试与声源诊断， cae 、数值化与可视化研究，噪声的主动控制技术。 - Abstract : by drilling holes on the surface , adding damping and isolating vibration to the roller , the vibration and noise radiation are not onl y reduced , but vibration energy of transmission to the surrounding objects is al s o restrained
文摘:通过对辊筒进行表面处理、附加阻尼装置和采用隔振措施,不但减少了辊筒的振动和噪声而且抑制了辊筒振动能量向支架、地基传递,避免二次结构声。
