| 1 | Recursive formulations for the method of reverberation-ray matrix and the application显示文摘A recursive formulation is proposed for the method of reverberation-ray matrix (MRRM) to exactly analyze the free vibration of a multi-span continuous rectangular Kirchhoff plate, which has two oppo- site simply-supported edges. In contrast to the traditional MRRM, numerical stability is achieved by using the present new formulation for high-order frequencies or/and for plates with large span-to-width ratios. The heavy computational cost of storage and memory are also cut down. An improved recursive formulation is further proposed by modifying the iterative formula to reduce the matrix inversion op- erations. Numerical examples are finally given to demonstrate the effectiveness and efficiency of the proposed recursive formulae. | ZHU Jun CHEN WeiQiu YE GuiRu Lü ChaoFeng | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，2： | 3 |

| 3 | ON THE FREE VIBRATION OF A SUBMERGED FGM HOLLOW SPHERE显示文摘The free vibration of a functionally graded material hollow sphere submerged in a compress-ible fluid medium is exactly analyzed.The sphere is assumed to be spherically isotropic with material consta-nts being inhomogeneous along the radial direction.By employing a separation technique as well as thespherical harmonics expansion method,the governing equations are simplified to an uncoupled second-orderordinary differential equation,and a coupled system of two such equations.Solutions to these equations aregiven when the elastic constants and the mass density are power functions of the radial coordinate.Numericalexamples are finaUy given to show the effect of the material gradient on the natural frequencies. | Ye Guiru Chen Weiqiu Cai Jinbiao Ding Haojiang | 2000 | Acta Mechanica Solida Sinica2000，13，3： | 1 |
| 4 | The Space Environment Monitors of Shenzhou Manned Spacecrafts显示文摘For the purpose of ensuring normal operations of Shenzhou (SZ) series of manned spacecrafts and cosmonauts' safety, Space Environment Monitors (SEM)are mounted on board SZ-2, 3, 4, 5. SEMs aim to detect the high energy particles, the low energy particles, charging potential, atmospheric desity and composition. Detection of SEMs enable us to understand better the space environment in the manned spacecraft's orbit, and to provide a good space environment services for the spacecraft and cosmonauts. In addition, by using the data from SEMs, we have achieved some scientific accomplishments, such as the energy spectra of precipitating electrons, the abnormal variety of atmospheric density and composition during geomagnetic disturbances, the electron angle distribution in the low orbit and so on. | XU Ying ZHU Guangwu WANG Shijin QIN Guotai LIANG Jinbao SUN Yueqiang HUANG Xiuying YANG Xiaochao WANG Yue WANG Chunqin YE Haihua JING Guiru | 2004 | 空间科学学报2004，24，z1： | 1 |
| 5 | Steering CO_(2)electrolysis selectivity by modulating the local reaction environment:An online DEMS approach for Cu electrodes显示文摘Electrochemical CO_(2)reduction is a typical surface-mediated reaction,with its reaction kinetics and product distributions largely dependent on the dynamic evolution of reactive species at the cathode–catholyte interface and on the resultant mass transport within the hydrodynamic boundary layer in the vicinity of the cathode.To resolve the complex local reaction environment of branching CO_(2)reduction pathways,we here present a dif-ferential electrochemical mass spectroscopic(DEMS)approach for Cu electrodes to investigate CO_(2)mass trans-port,the local concentration gradients of buffering anions,and the Cu surface topology effects on CO_(2)electrolysis selectivity at a temporal resolution of~400 ms.As a proof of concept,these tuning knobs were validated on an anion exchange membrane electrolyzer,which delivered a Faradaic efficiency of up to 40.4%and a partial current density of 121 mA cm^(-2)for CO_(2)-to-C_(2)H_(4)valorization.This methodology,which bridges the study of fundamental surface electrochemistry and the upgrading of practical electrolyzer performance,could be of general interest in helping to achieve a sustainable circular carbon economy. | Ke Ye Guiru Zhang Baoxin Ni Liang Guo Chengwei Deng Xiaodong Zhuang Changying Zhao Wen-Bin Cai Kun Jiang | 2023 | eScience2023，3，4： | 0 |
