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。

However, the difference between Hongge and Xinjie is also apparent, perhaps reflecting the source difference in the mantle. Relative to the Hongge intrusion the Xinjie intrusion is more depleted in Nd isotope ratio and enriched in REE and LILE. The Xinjie intrusion plots in the first quadrant in Sr-Nd diagram, which shows the Sr isotope-enriched and Nd isotope-depleted slightly feature. This indicates that the source of the Xinjie intrusion may had the mantle wedge signature.

但红格、新街岩体的源区又有所不同,新街岩体较红格岩体Nd同位素更亏损,稀土和大离子亲石元素更富集;新街岩体在Sr-Nd相关图上,位于第一象限,显示Sr同位素富集,Nd同位素略亏损特征,指示了新街岩体的源区可能有残留地幔楔的成分。

Through establishing the functional of the source pulse which is based on the concept of "usable energy" in the received pulse and then extremizing the functional by means of the calculus of variations, the mathematical models of the optimized source pulse waveforms are shown to be associated with the eigenfunctions of a homogeneous Fredholm linear integral equation of the second kind. An efficient algorithm is developed for numerically solving the integral equation models.

The forward analysis of source rocks is defined as a method to estimate the amount of depositional organic matter or burial organic matter, and ulteriorly to estimate their original potential of hydrocarbon generation of source rocks by using the information of sedimentary environments, features of living biomass and physical chemistry in water medium through the geobiological analysis of geoecology, geomicrobiology, molecular geobiology and biogeochemistry. Quality and quantity of depositjonal organic matter can be calculated according to the productivity and preservation environrnents.
