Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs

5、 up and out the side of the hole.,为了建造一个工作的蒸馏器,使用锋利的棍子或者石块挖一个四英尺宽三英尺深的坑。为了增加这个接水器(太阳能蒸馏器)的产量,尽量把坑挖在潮湿的地区。把杯子放在坑的最深处。然后把管子放在合适的位置,使得管子一端一致延伸到杯子中,剩余的管子一直朝上,外出延伸到坑的外面。,Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheets center down with a ro

6、ck. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.,下一步,用塑料薄板把坑覆盖住,塑料板的边缘用泥土加固,用一块石头把薄板的中心部位压低。现在塑料薄板能够形成一个45度倾斜面的圆锥体。薄板的最低端必须直接居中,距离杯子至多三英尺的距离。,The solar still works by crea

8、e you need a drink.,太阳能蒸馏器通过在塑料板下创造一个温室工作。地下水蒸发,而且会在薄板上聚集直到小的水滴形成,水滴从薄板的底部往下流,直到水流到杯子内。等盛水的容器装满的时候,你就可以通过管子把让人神清气爽的水吮吸出去,而不需要每一次需要喝水的时候损坏这个太阳能蒸馏器。,32.
