The variation Characters in space of coalbed thickness is a chief element in determining the degree of exploration of coalfield, but it has not been solved sufficiently in the past when people intends to solve the problem quantitatively. In this paper the writer introduced the variation-function theory in geostatistics and presented to application in determining the thickness stability and the variation characteristics in space of coalfield quantitatively with systematic and complete discussions....

By using the fundamental equations describing the evolution of an acoustic gravity wave (AGW) packet in an ambient wind,the variation characteristics of AGW's essential parameters in a region of wind shear are studied.It is shown that the variations of wavelength,phase velocity and propagation direction depend on the vertical structure of the wind and also on the direction of the wave with respect to the wind.The variation manner of AGW kinetic energy is related to the variation in the...

By using the fundamental equations describing the evolution of an acoustic gravity wave (AGW) packet in an ambient wind,the variation characteristics of AGW's essential parameters in a region of wind shear are studied.It is shown that the variations of wavelength,phase velocity and propagation direction depend on the vertical structure of the wind and also on the direction of the wave with respect to the wind.The variation manner of AGW kinetic energy is related to the variation in the spatial scale of AGW.For the upgoing gravity branch,an increase of kinetic energy of the wave packet is accompanied by an increase of the wavelength,while a decrease of the kinetic energy is accompanied by a decrease of the wavelength.For the upgoing acoustic branch,the situation is just opposite.It is also discussed that an AGW wavetrain propagates in the region of wind shear.It is shown that an increase of AGW energy density is accompanied by a decrease of intrinsic frequency,while a decrease of AGW energy density is accompanied by an increase of intrinsic frequency.

本文根据时空变化风场中声重波演变的基本方程,详细讨论了声重波的基本参量在垂直切变风场中的变化方式。结果表明,沿群路径上波长、相速和传播方向的变化取决于风场的垂直结构以及波风之间的相对方位。声重波扰动动能的变化与波空间尺度的变化存在一定的关系。对于上行重力波分支,波包动能的增加伴随着波长变长,波包动能减小伴随着波长变短;对于上行的声波分支,情况则相反。文中还讨论了常定的声重波波列在垂直切变风场中的传播问题,分析表明,声重波能量密度增加伴随着本征频率减小,能量密度减小伴随着本征频率增加。

This paper provides a statistical study of the variation of the Atmospheric Vorticity Area Index (VAI) during geomagnetic storms for 1966-1978. The results show that the influence of geomagnetic storms on VAI is very obvious. VAI increases evidently when geomagnetic storms occur, then VAI decreases, and the maximum decrease occurs on the fourth day after geomagnetic storms. But the variation characteristic of VAI during each type of geomagnetic stoms is different, and there is obvious season effect in...

本文分析了1966—1978年间地磁暴期间地球大气气旋的变化。在地磁暴发生后,大气涡度面积指数(VAI)出现明显的扰动。在磁暴发生后第2天VAI有一个明显的增加,然后下降,到第4天VAI下降到最小值。但是,不同的磁暴类型发生时,VAI的扰动特征是不同的,而且具有明显的季节效应。
