It is proved that both the positive generalized renewal sequence semigroup and the tame semi-p-function semigroup are Hungarian semigroups and possessed of the fundamental Delphic properties. Then the arithmetic properties of these two classes of the special semigroups are studied respectively.展开更多
In his paper (Phys., Lett., 94A(1983), p. 340),Tu Guizhang, based on a linear spectral problem, discussed the following hierarchy of coupled nonlinear evolution equations:

The characteristics of its erystal lattice are beneficial to dating of the formation age of Malan loess by using the TL technique. However, in doing so, abundant experimental facts must be possessed and a theoretical basis established.展开更多

INTRODUCTION Since it was discovered that cis-platin inhibited the cell division of E. coli and possessed antitumour activity, much study has been made on the relationship between the structure and the antitumour function of the platinum complexes. It was found that the cis-configuration of diacidato diammino platinum complexes possessed antitumour activity, but the trans-isomers did not, showing the dependence of展开更多
