罩上

Higher and higher it grew and always above it rose the bell of air, till the flower-bud formed safely within it: and at last the icy covering of the air-bell gave way and let the blossom through into the sunshine, the crystalline texture of its mauve petals sparkling like snow itself as if it bore the traces of the flight through which it had come.

它继续长高，头上总是戴着那个钟形的小汽罩，直到里面长好了花苞。最后，钟形小汽罩的外壳脱落，花就直接与阳光接触，紫红色的花瓣，莹净剔透，络脉有似雪花，好像还保留着它生长斗争中所历经的痕迹。

She was particularly fond of animals, and, besides her canary, whose cage hung on a nail in the massive wall of the keep by day, to the great annoyance of prisoners who relished an after-dinner nap, and was shrouded in an antimacassar on the parlour table at night, she kept several piebald mice and a restless revolving squirrel.

她特别喜欢动物，养着一只金丝雀，鸟笼子每天就挂在厚厚的城堡墙上一只钉子上。鸟的鸣唱，吵得那些想在午饭后打个盹儿的犯人苦恼不堪。夜晚，鸟笼就用布罩罩着，放在厅里的桌子上。她还养着几只花斑鼠，和一只不停地转着圈儿的松鼠。

In addition, the deflector can increase critical Reynolds number of the aerodynamic drag coefficient graph.

安装导流罩使得气动阻力系数曲线上的临界雷诺数增大；设置薄壁式的导流罩底边和驾驶室顶面之间的间隙，可以增强导流罩的减阻效果。

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。
