Key Laboratories of CAS


Laboratory of Cognitive Science (Beijing)

Director: Professor Chen, Lin

Established in 1988, this is the principal laboratory in the area of cognitive science in China. The Laboratory's founder, Professor Chen has advanced the hypothesis of the early perception of topological properties and is the Chief Scientist in the field. Research Areas: Visual perception; Perceptual organization; Selective attention; Memory and language with cognitive psychological, neuro-psychological and neutro-physiological (e.g. Brain mapping) approaches. Current projects: Computational complexity; Topological perception: a challenge to computational approaches to vision; Shape transformation in illusory conjunction; Illusion of inside/outside; The difference in roles of attention oriented with peripheral cues from that of attention oriented with central cues: a topological explanation; Early topological perception: evidence from EEG Brain mapping; Implicit and explicit memory of Chinese characters.


Laboratory of Internal Friction and Defects in Solids

Executive Director: Professor Hu, Jiankai

The laboratory was established in 1990 with three divisions: Low frequency internal friction, audio frequency internal friction, and Ultrasound divisions. Currently, the laboratory is developing international collaborations.

Research Areas: Defects in solids and their interaction; Microscopic mechanism of internal friction; Ultrasonic attenuation and velocity in solids; Dynamic behavior of internal friction; Acoustic microscopy; Ultrasonic nondestructive testing and evaluation. Current Projects: Internal friction and ultrasonic studies on high Tc superconductors; Al-Li alloy; Advanced composites; Nonlinear optical crystals; Nanosize materials.

Structure Research Laboratory

Director: Zhang, Yuheng, Professor of Physics
Deputy Directors:
	Zhu, Jingsheng
	Li, Xiaoguang
	Hu, Keliang

Founded in 1985, the laboratory has been equipped with large number of apparatus for investigating structure, and physical and chemical properties of materials. The lab has been available to Chinese and foreign scientists and scholars and started to receive the applications for research topics since 1985. Any valuable scientific cooperation from China and all over the world are warmly welcome.

Research Areas: New type high Tc super- conductors and super-conducting mechanism and micro- structures; Systems of Multi-layer films and Interface Physics; Condensed State Structure and Properties of Polymers; Information of Structures for Ancient Materials.
