In this paper, thermodynamics of irreversible processes has been applied for investigating the plasma in a uniform magnetic field. The current equations are derived and the effect of the magnetic field on the current is discussed. Effects of the magnetic field, diffusion and thermal diffusion on the current of a partially ionized plasma as well as the effect of the magnetic field on the diffusion arc discussed also.

In this paper we studied the Maxwell's equations in imhomogeneous and anisotropic media as an operator. It is defined in a bounded region, which can be comprehended as a resonant cavity in micro-wave technique. But these cavities are filled with ferrite, plasma or other gyrotropic medium, all these new media become more and more important in practice. We proved that under some concrete conditions imposed on μ, e and restrictions on the boundary value, the operator of Maxwell's equations becomes a symmetric...

In this paper we studied the Maxwell's equations in imhomogeneous and anisotropic media as an operator. It is defined in a bounded region, which can be comprehended as a resonant cavity in micro-wave technique. But these cavities are filled with ferrite, plasma or other gyrotropic medium, all these new media become more and more important in practice. We proved that under some concrete conditions imposed on μ, e and restrictions on the boundary value, the operator of Maxwell's equations becomes a symmetric one. The symmetry and self-adjoint property give much convenience in eigenfunction expansion problems. Besides, we derived the orthogonality of characteristic oscillation and reciprocity theorem in general.

在本文中,把在不均匀各向异性介质中的麦克斯韦方程看作算符,它定义在一个有界区域,可以被理解为微波技术中的谐振腔。但在这腔中充填着铁氧体,等离子体或其他各向异性介质,这些介质在应用中日益重要。文中证明了在某些、边界条件下,算符成为对称。而对称性和自伴性在本征函数展开中带来很多方便;此外我们推导了本征振动的正变性和互易定理。 如果不满足对称性,引入伴谐振腔的概念,所谓伴谐振腔在几何形状上和原来的腔相同,但、和边界条件不一样。它和自伴谐振腔在正交性和互易定理上有某些相似之处。

In this paper, we suggest one method of finding the Green tensor functions in whole space, which are defined in formula (3). Some times it is also called the elementary solution of the corresponding differential equation. All this method is based on Fourier transform. Owing to complexity, we are obliged to make some simplifications. Magneto-gyrotropic media and electric-gyrotropic media are considered separately. For magneto-gyrotropic medium, such as ferrite, μ, is a tensor while s remains scalar. Conversely,...

In this paper, we suggest one method of finding the Green tensor functions in whole space, which are defined in formula (3). Some times it is also called the elementary solution of the corresponding differential equation. All this method is based on Fourier transform. Owing to complexity, we are obliged to make some simplifications. Magneto-gyrotropic media and electric-gyrotropic media are considered separately. For magneto-gyrotropic medium, such as ferrite, μ, is a tensor while s remains scalar. Conversely, for electric-gyrotropic medium, such as plasma, e is tensor and μ remains scalar. Taking advantage of the smallness of matrix μp (defined in (15)) we make an expansion in power series of μp, and carry out the calculations in first order approximation. The concrete results are expressed in formulae (23)、(25)、(28)、(32) and (33). The physical meaning of Γ and the effective region of the asymptotic expansions are discussed.

本文提出一个方法,来推求在(3)式中所定义的、在全空间中的格林张量函数。它有时亦称为对应微分方程的基本解。这个方法是以富氏变换为基础。由于问题的复杂性,我们不得不作某些近似。首先,把各向异性介质分为两类,一类是磁迴旋介质,另一类是电迴旋介质。对于磁迴旋介质,如铁氧体,取为张量而ε为标量。而对电迴旋介质,如等离子体,取为张量而μ为标量。其次,由于矩障非常小(在(15)式中定义),我们可以把解展为的冪级数,并计算出一级近似。具体结果在式(23)、(25)、(28)、(32)和(33)中表示。最后对Г函数的物理意义和它的渐近展开式的有效范围作了讨论。
