Regional variation difference was very large with more ice in the eastern Antarctic, obviously less ice in the west Antarctic, both sides of the Antarctic Peninsula, especially in the Weddell Sea and the Bellingshausen Sea. The sea ice variation trend in the eastern and western Antarctic is always in opposite phase.

研究表明20世纪70年代后期是多冰期；80年代是少冰期；90年代南极海冰属于上升趋势，后期偏多，区域性变化差别大，东南极海冰偏多，西南极海冰即南极半岛两侧尤其是威德尔海区和别林斯高晋海的冰明显偏少。

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。
