摘要：
Numerical results are presented for the photoproduction of two-jet via resolved quasi-real photon at HERA in next-to-leading order (NLO) QCD. It shows that the NLO contribution is important and reliable in the two-jet invariant mass region M(JJ) is an element of [15,45] GeV and rapidity region y(jjlab) > -2 This may be used to explain the ZEUS results with an uncertainty of 20%. The dependences on renormalization and factorization scales are also investigated.

摘要：
The Levy stable analysis for tandem cascade model is performed. The Levy stable index mu of alpha-model is obtained by both Monte-Carlo simulation and analytical calculation. It is found that mu is increasing when the fluctuation becomes weaker, and vice versa, just as expected. It is shown that the Levy stable index of alpha-model depends mainly upon the model parameter alpha. Its weak dependence on the number lambda of branches in each elementary splitting is due to the normalization of probability in each step. The possible reason of the Levy stable index greater than 2 found experimentally is briefly discussed.

摘要：
The highly anisotropic phase space (known as longitudinal phase space) of multiparticle final states in high energy hh collisions is studied in detail. It is pointed out that the anisotropy of phase space should manifest itself not only in the dramatic difference in magnitude between the average transverse and longitudinal momenta, but also in the anisotropy of dynamical fluctuations in the two directions. It means that the particle distribution in phase space has the property of selfaffine fractal. A method for experimentally testing the selfaffine fractality and measuring its characteristic parameterHurst exponent is given. In addition, the correlation between the degree of longitudinal fractality and the magnitude of average transverse momentum is discussed. A new characteristic quantity- average transverse momentum per event- for de scribing the dynamical property of an event (hard, soft or ultrasoft) is proposed. A comparison of the results with experimental data is given.

摘要：
Sound pressure transformation properties at the pinna of laboratory mice Mus domesticus were studied by measuring the sound pressure level of a continuous tone at a series of frequencies at the tympanic membrane as a function of the position of a sound source under free-field stimulation conditions. The spectral transformation, the interaural spectral difference, the isopressure contours and the interaural pressure difference contours were plotted. Sound pressure transformation functions showed some prominent spectral notches throughout the frequency range tested (10-80 kHz). However, the notch frequency did not appear to be systematically related to sound direction. The study of interaural pressure difference demonstrated that, when delivered from some angles within the ipsilateral frontal hemisphere, the sound pressure at the tympanic membrane of certain frequencies may be lower than that determined at the corresponding contralateral angles. For each sound frequency tested, there was an angle (the acoustic axis) within the ipsilateral frontal hemisphere from which the delivered sound reached a maximal pressure level at the tympanic membrane. However, the acoustic axis often changed to a new angle after removal of the ipsilateral pinna. In addition, sound delivered from the acoustic axis did not always generate a maximal pressure transformation. The isopressure contours determined within 2-5 dB of the maximal pressure were circumscribed, and their contained angular areas were found to decrease with increasing sound frequency. The 2 dB maximal pressure area may appear at more than one angular area for some test frequencies. Removal of the ipsilateral pinna or modification of pinna posture expanded isopressure contours irregularly and split the 2 dB maximal pressure area into several parts. The sound pressure difference determined between the angles of maximal and minimal sound pressure (the maximal directionality) increased with sound frequency regardless of pinna posture. Acoustic gain of the pinna at the acoustic axis reached 6-12 dB, depending upon sound frequency. However, the pinna gain was not always maximal at the acoustic axis for a given frequency.

摘要：
Recent experimental data on the negative correlation between forward energy and transverse energy, which have been reported for the interactions of 14.6A GeV Si28 with Al, Cu, Au, and Pb, 60A and 200A GeV O16 and S32 with S, Cu, Ag, and Au, are investigated by a model based on the description of geometrical properties of nucleus-nucleus collision processes. A parameter, ellipticity e, which might describe the conversion of initial energy into that of radiated final-state hadrons is proposed.

摘要：
The novel generalized correlation of the nuclear spin-spin coupling constants with the atomic hybrids and net charges is employed to give a new relationship for calculating the directly bonded phosphorus-carbon coupling constants by use of the maximum bond order hybrid orbital procedure together with the extended Huckel molecular orbital calculation. The calculated coupling constants of phosphorus-carbon are all in good agreement with the experimental data, which shows that the new relationship obtained in the present paper is quite satisfactory for calculation of the phosphorus-carbon coupling constants.

It is shown that non-Abelian and non-linear effects in a quark-gluon plasma (QGP) can be considered by using the multiple time-scale method to investigate kinetic equations for a quark-gluon plasma, and the expression for the non-linear eigenfrequency shift due to non-linear and non-Abelian effects in a spatially uniform QGP is determined.

摘要：
The mechanism for producing slow, target associated particles in high energy heavy ion collisions is investigated. It is shown that the same mechanism which was proposed for hadron induced interactions is likely to appear also for heavy-ion reactions. The results indicate however a much weaker correlation between impact parameter and yield of slow particles.
