Energy dissipation techniques, widely used in solid physics previously, are proven to be sensitive also to changes in liquid structure. It has been suggested fr
A method simplifying the exteal force term for the Boltzmann equation is proposed, using the Chapman-Enskog asymptotic expansion technique. The relationship bet
We study the effects of welding speed, Marangoni convection and natural convection on heat transfer and melt flow in a laser full-penetration welding using a th
We report a diode-pumped cw Nd:YAG laser operating on the 4F3/2-4I9/2 transition at 946nm, for which a maximum output power of 4.5 W with a slope efficiency of
We describe a PVK-based photorefractive polymer composite doped with disperse red 1, poly-butylacrylate and TNF. Using the two-beam coupling experiment, we inve
Diamond films with [100] texture were prepared by a hot-filament chemical vapour deposition technique to fabricate particle detectors. The response of detectors
Based on a scalable and universal quantum network, quantum central processing unit, proposed in our previous paper [Chin. Phys. Left. 18 (2001)166], the whole q
We propose a quintessence model with a cosine-type potential, in which the scalar field φa possesses an O(N)inteal symmetry. The most prominent feature of this
