Thermal Diffusivity of Film/Substrate Structures Characterized by Transient Thermal Grating Method被引量：1
《Chinese Physics Letters》2008年第1期176-179,共4页徐晓东 马頔 张淑仪 罗爱华 KIYOTAKA Wasa 
Supported by the National Natural Science Foundation of China under Grant No 10574073.
Transient thermal grating method is used to measure the thermal diffusivity of absorbing films deposited on transparent substrates. According to periodically modulated dielectric constant variations and thermoelastic ...

Phase Shifts during Interaction between Two Solitons in Two-Dimensional Dusty Plasma
《Chinese Physics Letters》2007年第8期2312-2315,共4页栗生长 吴利华 林麦麦 段文山 
Supported by the National Natural Science Foundation of China under Grant Nos 10575082 and 10247008, the Scientific Research Foundation （SRF） for the Returned 0verseas Chinese Scholars （R0CF）, State Education Ministry （SEM）.
The dust acoustic solitary waves propagating in two different directions in two-dimensional dusty plasma are investigated. In order to study the soliton interactions in multi-dimensional systems, we extend the reducti...

Homogenization of Three-Dimensional Periodic Solid-Solid Elastic Composites
《Chinese Physics Letters》2007年第3期747-750,共4页倪青 程建春 
Supported by the Ministry of Education of China under Grant Nos 705017 and 20060284035, the Excellent Youth Science Foundation of China under Grant No 10125417, and the State Key Basic Research and Development Programme of China under Grant No 51315.
We develop an approach to homogenize three-dimensional periodic solid-solid elastic composites with cubic lattice at low frequencies, by using plane wave expansion and perturbation theory with respect to the long wave...

Liquid-Solid Interface Waves with Laser Ultrasonic and Mirage Effect被引量：1
《Chinese Physics Letters》2005年第12期3104-3106,共3页韩庆邦 王浩 钱梦騄 
Support by the National Natural Science Foundation under Grant Nos 10234060 and 10134020.
We experimentally investigate the transparent-liquid/solid （water/aluminum or steel） interface waves generated by laser pulses and detected by the Mirage effect, it is shown that nearly all kinds of liquid/solid int...
