在中亞细亞沙漠地区,伸展着苏联第二大湖——咸海。从帕来尔和天山山脉奔流而下的成千条小溪匯合成兩条大河——锡尔河和阿姆河。它們在沙漠上流过很长一段路后,帶着大量的泥沙和鹽質注入咸海。科学家們計算出,它們每年流入咸海的水达到500亿吨以上。在太陽的热力下,湖水大量蒸發,而鹽留下来。这样,每年大約有2,400万吨鹽蓄积在咸海里。但是咸海現在总共只有105亿吨鹽,算起来这只是440年间蓄积下来的,这与咸海在历史上和地質上的資料完全不符合。其余的鹽哪里去了? 这个問题多年来吸引了科学家們对咸海的兴趣。最伟
In the Central Asia Desert, the second largest lake in the Soviet Union, the Aral Sea, is stretched. Thousands of small streams running from Paler and the Tien Shan mountains merge to form two large rivers, the Syr Darya and Amu Darya. After a long way in the desert, they inject large amounts of silt and salt into the Aral Sea. Scientists have calculated that their annual water flow into the Aral Sea reaches more than 50 billion tons. In the heat of the sun, the lake evaporates a lot, leaving the salt behind. In this way, about 24 million tons of salt accumulates in the Aral Sea every year. However, the Aral Sea has a total of only 10.5 billion tons of salt, which is only 440 years old. This is totally inconsistent with the historical and geological data of the Aral Sea. Where did the rest of the salt go? This problem has attracted scientists for years to interest Aral Sea. The most
