A 2D velocity field of the eruptive prominence (EP) of 1991 March 5 is obtained from its spectral data observed at the Yunnan Observatory and the velocity distr
In Phys. Lett. A 313 (2003) 343 we have found that the self-reciprocal Hankel transformation (HT) is embodied in quantum mechanics by a transform between two en
The viscoelastic properties of melts of nanocomposites with partially exfoliated structures, which were composed of low-density polyethylene (LDPE) , ethylene v
The reaction mechanisms of HNCS with NH(X3∑) were theoretically investigated. The minimum energy paths (MEP) of the reaction were calculated by using the densi
A series of heterogeneous catalysts with Cp2TiCl2 supported on palygorskite were prepared and evaluated by ethylene slurry polymerizations. The so-called direct
The effects of Zr on the microstructures and mechanical properties of microalloyed steels have been investigated by mechanical tests and microstructural observa
A series of piperazine-based Gemini and Bola surfactants were synthesized. Gemini 1and 5 have well surface activities. Their critical micelle concentrations (cm
