The North-South Seismic Zone of China has been proposed only recently. There are many questions regarding this zone which need to be discussed. In this paper we try to describe the limits of this zone, and to show certain aspects of its activity from the point of view of the time, space and magnitude distributions of historical and contemporary earthquakes occured in this zone.We find that this zone extends nearly along the meridian 104° E, all the way from North to South; it is divided into two sections...

The North-South Seismic Zone of China has been proposed only recently. There are many questions regarding this zone which need to be discussed. In this paper we try to describe the limits of this zone, and to show certain aspects of its activity from the point of view of the time, space and magnitude distributions of historical and contemporary earthquakes occured in this zone.We find that this zone extends nearly along the meridian 104° E, all the way from North to South; it is divided into two sections at about the latitude 33° N. It seems that the locations of epicenters of large earthquakes have been migrating from the north toward the south section, since 1700 A. D. indicating possibly the two sec-tions of the zone can be connected as one. This point may be further evidenced by the unison of focal mechanism solutions of recent earthquakes occurring in this zone.

This paper reviews the phenomenological and microscopic theories of nematie liquid crystals. By using simple symmetry arguments, a phenomenological Landau free energy density expansion is derived in terms of the tensorial order parameter.The application of the Landau-de Gennes theory is then illustrated in three areas: the calculation of thermodynamic properties of the nematic-isotropic phase transition, the study of bulk nematie response to external disturbances, and the description of fluctuation and interfacial...

This paper reviews the phenomenological and microscopic theories of nematie liquid crystals. By using simple symmetry arguments, a phenomenological Landau free energy density expansion is derived in terms of the tensorial order parameter.The application of the Landau-de Gennes theory is then illustrated in three areas: the calculation of thermodynamic properties of the nematic-isotropic phase transition, the study of bulk nematie response to external disturbances, and the description of fluctuation and interfacial effects. The discussion on the microscopic theories of nematie liquid crystals is divided into two sections: one on theories based on steric repulsive interaction and the other on theories based on attractive interaction between the molecules. It is shown that whereas each type of theory illuminates some aspects of the physics underlying the existence of the nematie order, neither can give a comprehensive understanding of the nematie liquid crystalline state and its transition into the isotropic phase. The paper concludes by pointing out some unresolved problems and the probable direction for their solution.

In this article by applying the output equivalent circuit, a formula of input impedenceis deduced. With the typical data, curves of the real component Rin and the imaginarycomponent Xin of input impedence, which varies in accordance with the wavelength λare computed. The curve for Rin can be divided into two sections on the λ_H/4 point,thecurve to the left of this point appears to be a section of sharp uprising. The right portionof the curve has. a relatirely flat section of abput. 20% band width from the λ_H/4 point.It is better to choose the cutoff wavelength of H-section-guided transformer great thanλ_(CH)=(2λ~2_C-λ~2)~(1/2) When the length S of the transformer is chosen on the flat section ofcurve Rin, the broadband characteristics can be abtained. Hence, while desiyningbroadbanding magnetron H-section-guided transformer, we must take S=λ_h/4, whereλ_H is waveguide wavelength of a H-section-guided at the high frequency end of theband. This conclusion is confirmed by the magnetron practically designed.
