By means of further investigation of solid codes, the problem "Is every fd-domain uniformly dense" proposed by Yuqi Guo, C. M. Reis and G. Thierrin in 1988 is s
The MxHyTi3O7 (M=K, Fe, Zn, Co, Na, Ag) nanotubes were prepared by ion-exchange reactions, in which H2Ti3O7 nanotube reacted with salts of K2SO4, Na2SO4, Fe(NO3
The boundary element theory together with the optimization method is used to calculate the driving voltage weighting vector of a conformal array of underwater a
This paper discusses two problems: one is some important theories and algorithms of affine bracket algebra; the other is about their applications in mechanical
Two-dimensional (2D) self-assembly of two 1,3,2-dioxaborine derivatives was investigated by STM. The molecules consist of π system and steric end groups. A dro
High-pressure mafic granulites occurring as lenticular bodies within garnet-amphibolites in Kangxiwar Fault have been first reported in this paper. The P-T cond
Biorthogonal multiple wavelets are generated from refinable function vectors by using the multiresolution analysis. In this paper we provide a general method fo
