尺度

This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

本博士论文主要由如下几部分组成，首先对锋面结构、地形和非绝热加热对锋的影响、锋生环流及锋面附近中尺度系统动力学问题的历史与现状进行了综述，在此基础上提出需要进行研究的若干问题：(1)、半地转锋生理论直到今天仍是解释锋生过程的最合适的理论框架，但是通过与观测事实比较，人们发现半地转理论不能对许多锋面观测特征给出令人满意的回答，新的观测事实使问题更加突出，这就向人们提出：是什么原因导致半地转理论与实际观测的不符？

To enhance the accuracy of prediction of the futurology, it was necessary to capture the constant factors in the human society in order to clarify the positioning of a host of future variables in the time scale.

Thehigh-density array has threshold energy of about 2TeV. With the YangbajingAS γ array, upper limits of γ-ray fluxes from many high energy galacticcelestial objects including Crab Nebula and active galactic nuclei weremeasured at the energy around 10TeV, and the possible evidence of existing10TeV cosmic gamma ray burst was looked for. The Sun's shadow of cosmicrays has been observed and shift of the Sun's shadow resulted from the solarinterplanetary large scale magnetic field was found. And the ultra high energyspectrum of primary cosmic ray around the 'knee' was reached.
