一、引言目前我国的电力建设还不能满足国民经济和社会发展的需要，在电力供应紧张地区，有不少企业配备柴油发电机组自己发电。但是柴油发电机组属于高噪声动力机械，其噪声对环境的污染十分突出。采取有效、可靠和实用的方法及措施，降低柴油发电机组的噪声，就是一项非常有? I. INTRODUCTION At present, China’s power construction can not meet the needs of national economy and social development. In areas with tight power supply, many enterprises have equipped their own diesel generators to generate electricity. However, the diesel generator belongs to the high-noise power machinery, and its noise pollution on the environment is very prominent. It is very important to adopt effective, reliable and practical methods and measures to reduce the noise of diesel generating sets.
