The theory of electromagnetic wave propagation on multiconductor overhead lines presented in this paper mainly deals with the study of propagation of power line carrier,and other low and high frequency signals on power lines. It is an important part of the theory of electromagnetic wave propagation. The mathematical model for calculating propaga- tion characteristics of a line can be derived. In this paper, a general solution to the electromagnetic field equations of signals propagation along a line is obtained by using a more strict method.Carson's method as well as some other methods are also discussed.We first consider a z directed infinite horizontal wire located at (xc,yc)abovethe multilayer earth,as shown in Fig.1. The current in the conductor is assumed to have the form I = I0e-rz. According to the theory of electromagnetic fields,the six components of the total electromagnetic fields in any one of the" regions can be expressed by eq. (8),in terms of two vector potentials A and F. The fields on every interface surface of these potentials satisfy the continuity constraints of eq.(9).Therefore the z component of the electric field above the ground is obtained in eq.(10). In a multiconductor system, the electromagnetic-fields in any region are the summation of the fields produceed by currents in every conductor.The solution to the axial component Ezo above the one-layer earth is obtained in eq.(24).In the derivation above, the only approximation made is that the wire is thin, i.e. rc< yc. Carson in his paper made two other approximations, eqs. (27)and(30).If these approximations are applied to eq.(24), we can obtain Carson's formula(31). In this case a multiconductor line above the earth can be treated as a transmission line.Inother methods,fewer approximations and two-or three-layer earth are assumed, so that the results obtained are more precise than those by Carson's formula, but they are more complicated, and therefore Carson's formula is still more populary used.Under conditions of very high frequency and extraordinary earth condition and line construction, there will be serious errors in Carson's formula, and the other formulas have also limited application. The method presented in this paper is generally applicable.

Enstatites formed in different geological environments have been studiedby means of high resolution electron microscopy. The [010] and [012] struc-tural images clearly show the intergrowth of CLEN and OREN polymorphswhich is in agreement with the rules suggested by Buseck and Iijima. A meteoritesample was also examined to show a very high frequency of intergrowth ofthese two polymorphs in response to rapid cooling. The transformation ofOREN to CLEN induced by shear stress and Burgers vector the partial dislo-cation between them have been studied in great detail and the 13.3° transfor-mation mechanism put forward by Coe is favored.

利用高分辨电子显微镜(HREM)研究了不同地质条件下生成的顽火辉石。[010],[012]取向结构象清楚地显示出单斜顽火辉石(CLEN)和正交顽火辉石(OREN)共生现象,其特征与Buseck和Iijima总结的规律相一致。陨石中的顽火辉石由于经受急冷,所以多型体共生现象出现频率最高。本文还详细地研究了在切应力作用下引起的OREN向CLEN转变及它们间的部分位错Burgers矢量,结果符合Coe提出的13.3°转变机制。
