摘要：
There have been considerable studies on 'fractals' and their properties. Most of themare concentrated on the properties of sets and measures in R~d. Recently there hasbeen some interest in fractal subsets of Z~d.

摘要：
The combined effect of several noises has been proposed recently. It has displayed that the presence of the correlation between noises can change the properties of the stochastic processes. In this paper, a general effective Fokker–Planck equation (FPE) with correlated noises is derived. The stationary distributions and the moments of two kinetic models under two correlated noise sources are obtained. The effects of the interference of additive and multiplicative noises are analyzed.

摘要：
It is shown through theoretical analysis and Monte Carlo simulation that when the translational invariance of semi-inclusive density function is destroyed the bin-wise and strip integrals of this function are inequivalent. The different experimental results about the anomalous scaling behaviour of factorial moment in the variables (y, p perpendicular to, phi) and that of strip integral in the variable Q(2) is discussed briefly.

摘要：
By developing the ''tadpole graph method'' including the resummation of the hard thermal loops in the tadpole diagrams, a self-consistent method is proposed in the calculation of effective potential. It is shown that the calculated effective potential at finite temperature in the Higgs model is more self-consistent than the naive calculation. The two difficulties encountered in the naive calculations of the effective potential disappear naturally, The calculated results indicate that the symmetry restoration transition is of the first order.
摘要：
Charged particle pseudorapidity density distributions in Au induced reactions in nuclear emulsion at 10.7 A GeV have been measured. In peripheral events the shower particle distribution exhibits a two peak structure while in central collisions it has a Gaussian shape. The spectator protons appear in the second peak in the pseudorapidity spectra and exhibits a broader momentum distribution than expected from Fermi motion. The produced particle yield in central collisions is not substantially different from phenomenological descriptions based on data from O and S induced reactions.

摘要：
A novel, generalized correlation of the characteristic stretching frequencies with the atomic hybrids and net charges is employed to give a new, explicit relationship for calculating the P=S stretching frequencies by the use of the maximum bond order hybrid orbital procedure together with the extended Huckel molecular orbital calculation. The calculated numerical results show that the new relationship obtained in the present paper is quite satisfactory for the calculation of the characteristic P=S stretching frequencies for organophosphorus compounds.

摘要：
The ligand, ortho-bis[N,N-bis(2’-benzoimidazolyl methyl) amino]-trans-cyclohexane (CTB), is prepared by condensation of ortho-phenylene diamine and ortho-diamino-transcyclohexane-N,N,N’,N’-tetraacetic acid. The ligand reacted respectively with appropriate copper(1) salts to give binuclear Cu(1) coordination compounds, which have a general formula Cu<sub>2<sub/>(CTB)X<sub>2<sub/> (X=CIO<sub>4<sub/><sup>-<sup/>, Сl<sup>-<sup/> and BF<sub>4<sub/><sup>-<sup/>). The complex ion [Cu<sub>2<sub/>(CTB)]<sup>2+<sup/> in dimethyl formamide (DMF) take up oxygen in a 1:1 molar ratio when bubbling O<sub>2<sub/> or exposed to air. Moreover, the complexes undergo a quasi-reversible change with bubbling O<sub>2<sub/> and adding ascorbic acid (AA) and oxy-deoxy-cycles can be repeated more than six times. The electronic, fluorescence and ESR spectra of deoxy- and oxy-complexes show a strong resemblance to that o f deoxy- and oxy-hemocyanin (He) respectively. The oxygen adducts have been isolated.

摘要：
The ab initio maximum bond order hybrid orbital (MBOHO) procedure has been performed with an STO-3G basis set in order to study the correlativity between the ab initio MBOHO calculation results and the nuclear spin-spin coupling constants. The generalized relationship which involves the contributions of not only the hybrid orbitals, but also the net atomic charges has been applied with the calculated s-character of the MBOHOs including only the valence atomic orbitals and the net atomic charges to obtain concrete relationships for calculation of the nuclear spin-spin coupling constants of various CH, CC, CN and CF bonds. The coupling constants evaluated by use of these concrete relationships are in good agreement with the experimental data, which shows that the ab initio MBOHO procedure and the generalized relationship including also the net atomic charges are feasible for elucidating the nuclear spin-spin coupling constants between the directly bonded atoms.

Reactions of phosphorus trichloride (PCl3), thiophosphoryl trichloride (PSCl3) and tris(dialkylamino)phosphine (P(NR(2))(3)) with substituted thiohydrazides (<(1a)under bar>-(1) under bar) under a variety of conditions led to thirty one substituted 2,3-dihydro-1,3,4,2-thiadiazaphospholes (<(2a)under bar>-(1) under bar, <(3a)under bar>-(c) under bar, <(4a)under bar>-(1) under bar). The side-reactions leading to <(4h)under bar> and (5) under bar also are discussed. The elimination of HCl from 2-chloro-5-methylthio-2,3-dihydro-1,3,4,2-thiadiazaphosphole (<(2b)under bar>) by 1,8-diazabicyclo-[5,4,0]-undec-7-ene (''DBU'') gave rise to 5-methylthio-1,3,4,2-thiadiazaphosphole dimer ((6) under bar). The Staudinger reaction and sulfuration of 2-diethylamino-3-N-phenyl-5-methylthio-2,3-dihydro-1,3,4,2-thiadiazaphosphole (<(4a)under bar>) with Me(3)SiN(3) and S-8 result in the formation of 2-(trimethylsilyl)imino-((7) under bar) and 2-thiono-((8) under bar) substituted counterparts respectively. The structures of the above products were confirmed by elemental analysis, IR, MS, and H-1-NMR, C-13-NMR and P-31-NMR.
摘要：
The phase diagrams of four binary systems (C10H21NH3)2CoCl4−(C16H33NH3)2CoCl4, (C12H25NH3)2CoCl4−(C16H33NH3)2CoCl4, (C10H21NH3)2ZnCl4−(C16H33NH3)2ZnCl4 and (C12H25NH3)2ZnCl4−(C16H33NH3)2ZnCl4 were investigated by means of DSC. These six compounds and their binary mixtures can retain energies between 74 and 115 J/g during solid-state transformations at temperatures between 70 and 105°C, and they are therefore being considered for potential use in solar energy systems.

摘要：
The transient properties of a single-mode dye laser with correlations between additive and multiplicative white-noise terms are investigated theoretically. The mean, variance, and skewness of first-passage-time distributions for the white-noise-loss model and the white-noise-gain model are obtained. We find that (1) the mean first-passage time for the two models is not affected by the strength λ of the correlation between additive and multiplicative noise terms; (2) as λ is increased, the magnitudes of the variance and skewness of the two models are increased; and (3) under the same λ and the same pump level, the variance and skewness of the white-noise-gain model are larger than those of the white-noise-loss model.
摘要：
By means of adiabatically eliminating the upper level or levels of a Λ-configuration atom coupling to a two-mode quantized field, we have studied the influences of ac Stark shifts on the atomic coherent population trapping in two important atom-field coupling systems via nondegenerate Raman two-photon processes. The states of the field that trap the atom in its two nondegenerate lower levels are obtained, and the important roles of ac Stark shifts and properties of the atomic upper level or levels in the states of the trapping field in two Raman-coupling systems are also analyzed.

摘要：
A possible universal description of rapidity dependence of multiplicity distributions in high energy e(+)e(-), mu p, hh, hA and AA collisions is proposed based on a cluster mechanism, local charged compensation and its violation. It appears that there exist a statistical connection between multiplicity distribution in a full longitudinal phase space and that in a selected rapidity window with limited size.
摘要：
Early in the 1970s, some authors suggested that the electroweak gauge symmetry should be restored at high enough temperature and density. Recently the electroweak phase transition has attracted much attention, because it is of crucial importance for the baryon asymmetry of the universe. So it is required to discuss the electroweak phase transition in detail. The basical tool for studying the phase transition is effective potential, and naive calculation of the effective potential has two difficulties. Here we will propose a self-consistent calculation of the effecitve potential by the resummation of hard thermal loops, and use this improved method to discuss the symmetry-restored transition in the Higgs model.
