| 1 | Introduction to the Payloads and the Initial Observation Results of Chang'E-1显示文摘Chang'E-1,the orbiter circling the moon 200km above the moon surface,is the first Chinese Lunar exploration satellite.The satellite was successfully launched on 24th October 2007.There are 8 kinds of scientific payloads onboard,including the stereo camera,the laser altimeter,the Sagnac-based interferometer image spectrometer,the Gamma ray spectrometer,the X-ray spectrom-eter,the microwave radiometer,the high energy particle detector,the solar wind plasma detector and a supporting payload data management system.Chang'E-1 opened her eyes to look at the moon and took the first batch of lunar pictures after her stereo camera was switched on in 20th November 2007.Henceforth all the instruments are successfully switched on one by one.After a period of parameter adjustment and initial check out,all scientific instruments are now in their normal operating phase.In this paper,the payloads and the initial observation results are introduced. | SUN Huixian WU Ji DAI Shuwu ZHAO Baochang SHU Rong CHANG Jin WANG Huanyu ZHANG Xiaohui REN Qiongying CHEN Xiaomin OUYANG Ziyuan ZOU Yongliao | 2008 | 空间科学学报2008，28，5： | 4 |

| 4 | Propagation of elastic waves in a plate with rough surfaces显示文摘Abstract The characteristics of Lamb wave propagating in a solid plate with rough surfaces are studied on the basis of small perturbation approximation. The Rayleigh-Lamb frequency equation expressed with SA matrix is presented. The Rayleigh-Lamb frequency equation fora rough surface plate is different from that for a smooth surface plate, resulting in a small perturbation Δk on Lamb wave vector k. The imaginary part of Δk gives the attenuation caused by wave scattering. An experiment is designed to test our theoretical predications.By using wedge-shape pipes, different Lamb Wave modes are excited. The signals at different positions are received and analyzed to get the dispersion curves and attenuations of different modes. The experimental results are compared with the theoretical predications. | DAI Shuwu ZHANG Hailan(Institute of Acoustics, The Chinese Academy of Sciences Beijing 100080) | 2003 | Chinese Journal of Acoustics2003，22，3： | 0 |
| 5 | Elastic ware scattering from rough free surfaces of solids显示文摘Elastic wave scattering by a rough free surface of solids is analyzed. The analysis is based on the concept of scattering amplitude (SA) and perturbation approximation. The SA method is very convenient for rough surface scattering problems. By solving the boundary equations, the first and the second order solutions of approximate scattering amplitude are obtained. The general solutions are used for, as an example, the wave scattering by rough surfaces with Gaussian distribution. The mean field and variance are given. Finally, an experiment is designed to verifv the theoretical predications. | DAI Shuwu ZHANG Hailan(Institute of Acoustics, Chinese Academy of Sciences Beijing 100080) | 2003 | Chinese Journal of Acoustics2003，22，3： | 0 |
