| 1 | Simulation of molecular dynamics of silver subcritical nuclei and crystal clusters during solidification显示文摘Molecular dynamics simulation is carried out to investigate the effects of cooling rate on the final configurations of silver after rapid solidification. The cooling rate for the formation of a silver amorphous phase is determined by analyzing its pair distribution function, H-A bond index, and the largest crystal cluster. Further, the equilibrium structures of the subcritical nuclei and crystal clusters are studied. The results show that the solidified microstructure is composed of a mixture of crystal clusters and amorphous phases at a certain cooling rate range. The size of the largest crystal cluster decreases with the increasing cooling rate, and it completely disappears when the cooling rate exceeds a critical value. The structures of the subcritical nuclei and the largest crystal cluster are composed of lamellar structures of fcc and hcp atoms, indicating that the lamellar structure of fcc and hcp atoms in the silver crystal originates from nucleation, and not from the growth of crystals. | JIAN ZengYun1, CHEN Ji1, CHANG FangE1, ZENG Zhao1, HE Tan1 & JIE WanQi2 1 School of Materials Science and Engineering, Xi’an Technological University, Xi’an 710032, China 2 State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi’an 710072, China | 2010 | Science China(Technological Sciences)2010，53，12： | 3 |

| 6 | Three New Saikosaponin-like Compounds from Polycarpon prostratum显示文摘Three new saikosaponin-like compounds (named prostratoside F-H) were isolated from the whole plants of Polycarpon prostratum (Forssk.) Aschers. et Schwein. ex Aschers. By detailed spectroscopic analysis, their structures were determined as 13β, 28-epoxy-16-keto-22α, 23-dihydroxyolean-11-en-3β-yl-α-L-arabinopyranoside, 13β, 28-epoxy-16-keto-23-hydroxy-ole- an-11-en-3β-yl-α-L-arabinopyranoside and 13β, 28-epoxy-16-keto-22α-hydroxyolean-11-en-3β- yl-α-L-arabinopyranoside, respectively. | Zhong Tao DING1,2, Jun ZHOU1*, Ning Hua TAN1, Shi Ming DENG1 1Laboratory of Phytochemistry, Kunming Institute of Botany, Academia Sinica, Kunming 650204 2Department of Chemistry, Yunnan University, Kunming 650091 | 2001 | Chinese Chemical Letters2001，12，8： | 1 |

| 8 | A Class of Iterative Formulae for Solving Equations显示文摘Using the forms of Newton iterative function, the iterative function of Newton's method to handle the problem of multiple roots and the Halley iterative function, we give a class of iterative formulae for solving equations in one variable in this paper and show that their convergence order is at least quadratic. At last we employ our methods to solve some non-linear equations and compare them with Newton's method and Halley's method. Numerical results show that our iteration schemes are convergent if we choose two suitable parametric functions λ(x) and μ(x). Therefore, our iteration schemes are feasible and effective. | Sheng Feng LI1,2,3, Jie Qing TAN1,2, Jin XIE1,2,4, Xing HUO1,2 1.
