1.Updated and expanded faction following: - Carthage, Barbara, Greeks, Macedonians.
3.The 13C and 119Sn NMR spectra of CDC13 solutions of aliphatic and aromatic tricyclohexyltin (IV) carboxylates have been recorded.
4.SYNTHESIS AND REACTION OF BIS(CYCLOPENTENYLCYCLOPENTADIENYL) Ⅳ B GROUP METAL DERIVATIVES
6.any of a series of univalent groups of the general formula CnH2n+1 derived from aliphatic hydrocarbons.
7.A Native American people formerly inhabiting the southern Great Plains, with a present-day population in southwest Oklahoma. The Kiowa migrated onto the plains in the late17th century from an earlier territory in western Montana.
8.The recent advances of the synthesis of alkeny l substituted metallocene complexes (Ti，Zr，Hf)， the chemical reactions in the double bond of the substituted group， and the application of these complexes in polymerization of α-Olefins are reviewed.
9.In this paper the bond-parameter function, size factor ,and therefore theparabola method proposed by one of the authors(Zhang Bangwei) are used to predict thesolid solubilities for binary alloys based on Pm and Tm metals. It is believed that theprediction is reliable because the theoretical research resuults based on 18 non-transitionmetals ,23 transition metals,13 rare earth metals and 3 actinide metals are in good a-greement with the experiments.
