| 7. | The thermal properties of medium silicon - molybdenum vermicular iron are about three times of that of normal vermicular iron , so it is an ideal material for producing manifold
中硅钼蠕铁的抗热疲劳性能为普通蠕铁的3倍，因而是制造排气歧管的理想材料。 |
| 8. | The exhaust gas spews out of the exhaust valve and enters into the muffler along the exhaust manifold before draining into the atmosphere from the tail pipe . this process yields wide band exhaust noise
发动机废气从排气门高速冲出，沿着排气歧管进入消声器，最后从尾管排入大气，在这一过程中产生了宽频带的排气噪声。 |
| 9. | For the manifold of sedan engine , the hest thermal fatigue properties can be obtained by keeping the percent of vermicular graphite at about 50 % , therefore it shouldn ' t he considered that the lowest e . g . percent limit of 50 % specified in chinese vermicular iron standard is too lower , and it is also not proper to take the v . g . percent as the basis for judging the level of production technology
摘要对轿车发动机排气歧管而言，蠕化率控制在50 %左右可以获得最佳的抗热疲劳性能，因此不能认为我国的蠕铁标准中规定的蠕化率高于50 %的要求偏低了，也不能把蠕化率的高低作为衡量工艺水平的依据。 |
| 10. | The exhaust noise contains complex noise elements , including the exhaust noise with a base frequency measured in the number of exhausts in unit time , the resonance noise of the gas column in the pipe , the gas stream blowing noise at the exhaust manifold , the exhaust gas jetting and impact noise , the helmholtz resonance noise of the cylinder , the karman eddy noise and the turbulent noise inside the exhaust system
排气噪声包含了复杂的噪声成分：以单位时间内排气次数为基频的排气噪声、管道内气柱共振噪声、排气歧管处的气流吹气噪声、废气喷注和冲击噪声、汽缸的亥姆霍兹共振噪声、卡门涡流噪声及排气系统内部的湍流噪声等。 |
