    In this paper, we discuss the problem of the local energy content in gravitational fields. A new total energy-momentum density pseudo-tensor of gravitational field is given In this paper. The energy content in any part of a gravitational field given by the new pseudo-tensor is an invariant under arbitrary purely spatial transformation, hence the local energy content in the gravitational field has a well-defined physical meaning.

    In this paper, we discuss the problem of the local energy content in gravitational fields. A new total energy-momentum density pseudo-tensor of gravitational field is given In this paper. The energy content in any part of a gravitational field given by the new pseudo-tensor is an invariant under arbitrary purely spatial transformation, hence the local energy content in the gravitational field has a well-defined physical meaning. For the energy and momentum of a Schwarzschild gravitational field, the results given by the new pseudo-tensor are more reasonable than those given by other pseudo-tensors pro-posed in the literatures of the general theory of relativity.

    In this paper the existence of solvability for the following generalized boundary value problems is discussed.Let be the parabolic differential operator defined in the region Ω×[0,T] in a n+1 dimensional space and Ω be the bounded region with a bound S in a n dimensional Euclidean space En The problem of whether there exists a regular solution for the second order parabolic equationon Ω×[0,T] satisfying the following initial and boundary conditions is taken into consideration.If ψ(P) is continuous at point P,thenIf P∈Ω (or P∈Ω) and approaches to the point Q∈S along the conormal of S,thenalmost everywhere over S,where L is refered to as the operator in 1.Of the functions above-mentioned,ψ(P) is piecewise continuous on Ω,and ψ(Q,t)and ψ1(Q,t) are the arbitrary Lebesgue integrable functions with respect to Q over S and also continuous with respect to t With the aid of both the double layer and the single layer potential functions,these problems can be reduced to the linear integral equations solved with definite conditions including Lebesgue integrable free terms As a consequence,the existence of regular solutions for the problems with interior and exterior boundary values is proved. Here the first interior boundary value problems are emphatically discussed in detail The main results are expressed asTheorem 1.If1° aij(P,t)∈C2(Ω)(i,j=1,...,n) with respect to x1,...,xn(the coordinates of point P) and is of Holder's continuity with respect to t×λ[0,T];3° let S be the boundary surface of the bounded region Ω,S∈A1+λ;then,for any Lebesgue ψ(Q,t),which is integrable with respect to Q over S and continuous with respect to t∈[0,T],there exists the regular solution u (P,t) for (u)=0 satisfying the initial condition u(P,0)=0 and the interior boundary condition shown as form(3)Theorem 2.If1° S∈A1+λ,f(P,t)∈C(Q) (Q=Ω×[0,T)) and also satisfies the Holder's condition with respect to P;2° aij(P,t),bi(P,t),c(P,t) satisfy their relevant conditions respectively and aij(P,t) is of Holder's continuity with respect to t∈[0,T] then,for any ψ(P) which is piecewise continuous on Ω and any Lebesgue integrable ψ(Q,t) with respect to Q over S which is continuous with respect to t∈[0,T],there always exists a regular solution of the nonhomogeneous equation(1) satisfying the initial condition (2) and the interior boundary condition (3).The regular solution u(P,t) may be expressed as

    A generalized dispersion relation for electromagnetic two.stream instabilitieshas been obtained and analyzed.The results show that there is an electromagetictwo.stream instability that is sensitive to the thermal velocity spread of particles.The dispersion relation for cyclotron wave instability is computed and the regionin which the instability is to take place and the optimal value for excitinginstability are obrained.The main results are as follows:1)The regions in K-space for the electro.magnetic cyclotron(R—c or L—c)wave instabilities areand K_ZV_D/ω(Bi)>K_Z~2V~2/ω_(Bi)~2≥0 when K_ZV_D/ω_(Bi)≤4K_ZV_D/ω_(Bi)>K_Z~2V_A~2/ω(Bi)>K_ZV_D/ω_(Bi)-4,when K_ZV_D/ω_(Bi)>4where V_A=cω_(Bi)/_ω(Bi)is the Alfvén speed,V_D is the relative speed between ionsand electrons,ω_(Bi)=eBo/Mc is the cyclotron frequency of ions.2)The optimal value of K_ZV_D/ω_(Bi),at which we can obtain the largest region and the growth rate γ for the instabilities is 4,that is K_ZV_D/ω_(Bi)≈4.3)The solution of the dispersion relation for the ordinaty wave instabilitywith K⊥B_0 can be expressed as follows:(ω/ω_(pe))~2=(ω_(Be)/ω_()pe)~2+K_x~2V_(the)~2/ω_()pe-2(V_o/c)~2/1+2(ω_(pe)/K_xc)~2,from which we can obtain such a condition that the electromagnetic two-streaminstability occurs,(V_o/c)~2/1+2(ω_()pe/K_xc)~2>ω_(Be)~2/2ω_(?)~2+K_z~2V_(the)~2/2ω_(?)~2,that is,the magnetic field B_o and the temperature of the plasma areunfavourable for this instability.
