In this letter, a mathematical model for structure of ideal quasicrystal lattices, which is similar to that obtained by Peng Zhizhong (Dec. 1985), has been set up. This model describes very beautifully the following p...
The important progress of the superconductivity in R-Ba(Sr)-Cu-O system (R=La, Y)made by Zhao Zhongxian, Bednorz and Cava et al. has interested the science and technology circles greatly. In order to understand the me...
In the nineteenth century, scientists discovered that the tadpole-like larva of ascidian had a unique tail which has a central supporting rod and along the dorsum of which there is a tubular nerve cord, i.e. the centr...
With respect to the relation between the changes of clay mineralogy in the cores of marine deposits and the paleoclimatic vicissitudes, two completely different viewpoints prevail in the international circles today. O...
The effects of thermodynamics on the Qinghai-Xizang Plateau is a problem that has for years received much attention from the meteorological circles in China as well as in other countries. It has been verified by many ...
We have determined the solubilities of m-nitrobenzoic acid in aqueous solutions of LiCl, LiBr, NaCl, NaBr, KCl, KBr, SrCl2, and BaCl2 (from Cs = 0 to Cs = 1n) at 15°, 25°, 35°, and 45℃ (in the case of KBr an ad...
