1. To fully exert the advantage of that Antarctic Zhongshan Station is located within polar cusp region and dayside auroral zone, we study the characteristics of cusp region convection and dayside auroral motility by the data of advanced instruments installed in Zhongshan station and HF Radar data from Syowa station, and investigate the relationship between them.
充分发挥我国南极中山站地处极隙区和日侧极光带的优越位置,利用站上已有的先进观测设备和日本昭和站HF雷达观测数据研究极隙区对流特性、日侧极光的运动特性,探明两者之间的相互关系。
2. In general, biological effects will become as a main driving force in the seasonal ice zone in austral summer, for example, it is strongly controlled by biological factor inside of Prydz Bay in austral summer as a strong sink of atmospheric 〓. In other regions, however, hydrological processes are still dominate distributions of 〓, for example, in the Antarctic Divergence waters outside of Prydz Bay, due to a upwelling of the Circumpolar Deep Water, they present as a source more than as a sink because of their containing much enriched 〓. Thus, the feature of distributions of 〓 in ice zone are dominated by biological driving force in general, but in special regions the hydrological process would still be dominating.
在海冰区夏季的高生产力季节,生物影响通常都能够发展成〓的主要调控因子,比如,夏季普里兹湾湾内地区全部被生物过程影响所主控,并成为〓的一个强汇区;但在一些海区,水文物理过程依然可以主控着〓的变化,比如普里兹湾外的南极辐散带,由于绕极深层水的向上涌升,本来是强汇的普里兹湾一下子变成大气〓的源区,这是由于受到富含〓的深层水影响的原因,所以,虽然整体上,夏季海冰区〓的分布特征主要由生物影响所主控,但在一些局部的海区水文物理过程仍然产生控制作用。
3. By analyzing the above characteristics of movements of plates globally, we can deduce the following understandings on the kinematics and dynamics of plate tectonics:(1) the mantle flows which result in the movement of plates at the global scale can be divided into sub-flows in the directions of the longitude and latitude, which lead to the oblique movement of many plates; (2) the outer shell of the Earth with characteristics of the double-asymmetry of the Earth shown by lower order geoid is the mechanical precondition to the developments of the oceanic ridges and subduction zones; (3) the complicated phenomena of transpression and transtention along the equatorial disharmony zone maybe result from the velocity difference of rotation between the Southern Hemisphere and the Northern Hemisphere and non-superposition of the centroid of the Earth with its geometrical center; (4) further study on the movement away from the pole of the Antarctic Plate related to the Peri-Antarctic oceanic ridge is needed.
分析上述运动的分区展布,可推论以下几点运动动力学的认识:①拖动全球板块一级运动势态的地幔流可分解为由南极区向北的径向流与由大西洋洋脊和东南太平洋洋脊的东西两侧纬向流的二元动力联合作用,从而造成全球性指向北东和北西的斜向运动;②以重力大地水准面所展现的低阶双重非对称的地球,是引导表壳发育张裂洋脊带和汇聚俯冲带的力学条件;③沿赤道两侧不协调运动带呈现压扭、张扭的复杂变动除了南半球与北半球地幔流在运动指向和速度的差异而造成之外,还可能与地球质心的偏心和南、北半球自转速度的差异变化有关;④南极洲相对环南极洋脊的偏极分流运动还有待进一步研究。

6. The global change appears to affect the Arctic and Antarctic regions such as the events of ozone hole in the Antarctic atmosphere and north moving of permafrost zone in the Arctic region.
同时,南极上空臭氧空洞的出现,北极地区冻土带的北移等都表明全球变化也在明显地影响着两极。
