Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.

通过选用耐油性好的橡胶隔振器减少固体传声,可降低噪声约2 dB;设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB,并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点,不需增加强制通风措施;在生产车间四周墙壁和顶棚上敷设吸声体,最大可降低空间噪声8 dB;根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。

Based on a series of signal process and noise source identification techniques, especially the major noise source identification methods, such as expurgation method, sound intensity analysis, spectrum analysis vibro-acoustic correlation analysis and so on, the pass-by noise control of SC7080A and SC6360B are studied in detail. By the roadway and dais experiments, the major noise and radiating parts are identified and some economical controlling methods are made. For the SC7080A, to control the emissing noise from the intake and shell vibration of air cleaner, a intake muffler is installed between the air cleaner and intake valve. Based on the theory of Helmholtz resonator, One three-parallel-connected resonant silencer is designed and trial-manufactured. For the SC6360B, the attenuation performance of exhaust muffler in high frequency region is improved. To reduce the vibration noise of shell part, the structure of oil sump tank, exhaust manifold shield and exhaust manifold shield are analyzed and improved. At the same time, some measures, such as sound absorption, sound insulation, are taken to reduce the noise of engine surface emissivity and a sound shield is designed.

本文首先综述了目前国内外汽车加速噪声控制的现状、主要方法和技术措施,在此基础上,结合SC7080A和SC6350B汽车的车外加速噪声水平及现状,综合运用分别运行法、声强法、频谱分析法、声振相干函数法等现代噪声源识别方法,对SC7080A和SC6360B汽车进行了准确详细的车外加速噪声源识别并提出了经济可行的控制方案,针对SC7080A,主要在空气滤清器和进气阀门之间的进气管道上加装进气消声器,抑制空气滤清器壳体表面和进气口两处的噪声辐射,根据Helmholtz共振腔原理设计了三腔并联旁支型共振消声器,并进行了工程化设计和试制;针对SC6360B,主要改善了排气消声器在高频段的消声性能,对罩壳类零件进行了结构改进,降低了其表面噪声的辐射,并对发动机舱进行了吸声、隔声处理,设计了发动机隔声罩。

These descriptions are brief, but based on them it is indeterminable and has disadvantage in system design and direct implementation. On the other hand, these works mostly focus on describing variants behaviors of Ambient calculus in one level, which makes it complicated to understand clearly how these variants behaviors work and how they work together. As a result, based on the unit ambient of Ambient calculus, a three-level semantics description framework is given for Ambient calculus.

这种描述方式尽管简洁,一方面却具有不确定性,不利于实际的网络计算系统的设计和直接实现;另一方面,这种语义描述方式均在一个层次上描述Ambient演算系统中的各种行为语义,使得Ambient演算中各种计算行为纠缠在一起,复杂而难以理解。
