**Abstract:**

On the basis of the straton model

^{[1]},using the general groundstate wave functionsof mesons and baryons given in ref.[2],we have constructed under some specific as-sumptions the meson and baryon wave functions without

*SU*

_{6}symmetry.We applythese wave functions to explain the mesonic and baryonic properties of the electroma-gnetic and weak interactions;many results obtained are in agreement with the experi-ments.By using the 1/2

^{+}-baryon wave functions without

*SU*

_{6}symmetry,we obtain ananomalous magnetic moment for the proton.There is no need to introduce an ano-malous magnetic moment for the straton in the effective Hamiltonian of electromag-netic interaction between stratons.Similarly,the magnetic moment of the neutroncan also be explained.

_{(1;k)}denotes the normalized invariant inclusive cross section of

*k*closely neigh-boring particles.It follows that the inclusive the spectra of nearby particles arequalitatively different from the usual ones.The generalized form of the Feynman-Yang scaling for the case of

**Abstract:**

In this paper,we describe a proposal for solving the tracking problem in power supplies for separated function magnet systems of fast cycling synchrotrons.Formulas for calculating the tolerances of the parameters which influence tracking accuracy are given.

**Abstract:**

In this paper a new bag model of hadrons,the“Rubber Bag”model,is proposed.This model treats each hadron as a bag system in the centre-of-mass frame.The bag,with its outer radius

*R*and inner radius（

_{e}*R*-D）,is characterized by its“averagesurface tension”

_{c}*T*and the quarks are confined in it“temporarily”.This model isa field theoretical model which can also be used for quantitative calculations.Thus,ithas the merits of the SLAC bag model as well as those of the MIT bag model.

**Abstract:**

Using Glauber theory including the nucleon spin effects,the proton-

^{4}He elastic scattering differential cross section and polarization at energies in the region 0.35—23.1 GeV are calculated.The results show that,after including the spin-flip terms,we can explain the differential cross section data and describe qualitatively the polarization.

**Abstract:**

Assuming that the nuclear binding is dominated by a real scalar meson field,the mass of this meson is calculated to be 472 MeV from the nuclear surface tension coeffici-ent,by Thomas-Fermi method and Van der Waals approximation.The agreement between this value and the mass of a chief scalar meson in the OBEP theory of nuclear force indicates that a more serious investigation of above assumption should be valuable.

**Abstract:**

In the width fluctuation correction calculation of compound nuclear reaction,we have made a unified treatment of the reaction processes of particle emission,gamma emission and fission processes,in which the residual nuclei can be in discrete states or in the continuum.The calculated results of inelastic cross sections and the cross sec-tions for particle emission,gamma emission and fission processes are self-consistent.

**Abstract:**

In this paper we have applied the field-current relations in the weak form to a series of processes of the radial excited states.After assuming some properties for thematrix element we may obtain the proportional relations for the processes of the radial excited states.These relations agre with experiments reasonably.

**Abstract:**

It is shown that there exist some simple relations among the moments of inertia of multi-quasi-particle excitation bands,provided the blocking effect is neglected.Systema-tical discrepancy exists between the experimental result and the quasi-particle prediction.

In this note,we discuss the cross-sections of the production of

**Abstract:**

In this paper,the photoproduction of the relativistic para-positronium and muonium,similar to the Primakoff effect,is calculated using the perturbation expansion of the quantized composite field theory and relativistic B-S wave functions.A new term multiplied to the form factor is obtained,which makes the amplitudes different from what one obtains from the point-model calculation usually used in this kind of processes.It suggests that the same effect mentioned above may occur in the ordinary primakoff effect too.

**Abstract:**

A statistical quark model is proposed which combines the quark model with the statistical thermodynamical model.The relative multiplicity of different mesons produced in the small longitudinal momentum region is calculated.The result is in agreement with the experimental data.

**Abstract:**

In this note the spectra of leptons and stratons are conjectured and some interes-ting results are obtained:If the number of the generations of leptons are four,then the next lepton mass is about 4.2 GeV,and if the number of the leptons are five,then the fourth lepton mass is about 5.6 GeV.For stratons,if the number of flavour is six,then the mass of the meson with(tt)as a bound state is about 15 GeV,and if the number of flavour is eight,then it is about 23 GeV.
