我们习惯于以海平面为准来测量海平面以上的物体的高度。但是,通常的涨潮与落潮、风暴、气压的高低都会影响这个基本“恒量”的数值。最近又发现一个新的因素。苏联“斯卡依列伯”宇宙站装上了雷达(无线电)高度计,它能够精确测量全世界各海洋海面高度。这个灵敏的仪器,在几秒钟以内就可以做七次准确的测量。经过一系列的测量分析,发现在大西洋海面,甚至在南卡罗里洲和波多黎哥岛之间比较小的海域内也存在高度差。在伯列依克水下高地海底降低地区,海面也比周围地区明显的低,特别是波多黎哥海下凹地的海面就更明显的低落。当“斯卡依列伯”的轨道通向巴西上空时,表示 We are accustomed to measuring the height of objects above sea level with sea level prevailing. However, the usual high and low tides, storms and barometric pressure all affect this basic “constant” value. Recently discovered a new factor. The Soviet Union “Sarkozy” space station is equipped with a radar (radio) altimeter that accurately measures the sea surface height of all seas around the world. This sensitive instrument can make seven accurate measurements in seconds. After a series of measurements, it was found that there was also a height difference in the Atlantic Ocean, even in the relatively small waters between South Carolina and Puerto Rico. In the area beneath the Burilside submarine heights, the sea level is also significantly lower than in the surrounding area, especially when the sea level in the lower reaches of Puerto Rico is even more pronounced. When the track of “Sarkar-Lieber” leads to Brazil, he said
