摘要
讨论优先控制交叉口车辆运行特性 ,对车辆噪声的各个组成部分进行分析 ,提出优先控制交叉口总的交通噪声的计算公式 ;并利用计算机模拟对无控制交叉口和优先控制交叉口交通噪声值进行计算和对比分析 。
In this title, vehicle operation characters in priority intersection are discussed, and the vehicle noise composition is analysed. Then the calculating equation of overall traffic noise in priority intersection is put up. Computer simulation is also used to calculate the traffic noise in unsignalized and priority intersections, and several important properties of traffic noise in priority intersection are put forward Key words:Priority intersection;Noiseater\|quenched samples and absorbed\|electron microstructure of Mn are analyzed. The results have shown the well\|distributed element Mn and the sintering mechanism of Fe\|SM\|C alloy system.
