Nonlinear magneto-electric response of a giant magnetostrictive/piezoelectric composite cylinder

引用

Acta Mechanica Sinica 2012年第2期28卷 385-392页

作者： yuan-wen gao Juan-Juan Zhang Key Laboratory of Mechanics on Western Disaster and Environment Ministry of Education and College of Civil Engineering and MechanicsLanzhou University730000 LanzhouChina

In this study, we investigate the nonlinear cou- pling magneto-electric （ME） effect of a giant magnetostric- tive/piezoelectric composite cylinder. The nonlinear consti- tutive relations of the ME material are taken into account, and the influences of the nonlinear material properties on the ME effect are investigated for the static and dynamic cases, respectively. The influences of different constraint conditions on the ME effect are discussed. In the dynamic case considering nonlinear material properties, the double frequency ME response （The response frequency is twice the applied magnetic frequency） is obtained and discussed, which can be used to explain the experiment phenomenon in which the input signal with frequency f is converted to the output signal with 2f in ME laminated structures. Some calculations on nonlinear ME effect are conducted. The obtained results indicate that the nonlinear material properties affect not only the magnitude of the ME effect in the static case but also the ME response frequency in the dynamic case

The Crystalline Changes of Starch from Rhizoma Dioscorea by Acid Hydrolysis

引用

Chinese Chemical Letters 2006年第9期17卷 1255-1258页

作者： Shu Jun WANG wen yuan gao Jing Lin YU Pei Gen XIAO College of Pharmaceuticals and Biotechnology Tianjin University Tianjin 300072 School of Science Tianjin University Tianjin 300072 Institute of Medicinal Plant Chinese Academy of Medical Sciences and Peking Union Medical College Beijing 100094

The changes in crystalline properties of starch from Rhizoma Dioscorea by acid hydrolysis was characterized by X-Ray diffractometry （XRD）. The results revealed that the crystalline type of Rhizoma Dioscorea starch changed from C-type to A-type after 16 days of the acid hydrolysis. This phenomenon was different from that of other starches subjected to the acid hydrolysis. The results revealed that the B-polymorphs of C-type starch constituted the amorphous regions while the crystalline areas were mainly composed of A-polymorphs. The degree of crystallinity of the acid-thinned starch increased gradually with the time of acid hydrolysis.
