实验表明，无铅锡膏在钢网上的流动性很差，导致沉积面积，体积和高度的最大值和最小值的波动变化十分明显；

Experimental results show that lead-free solder paste in the poor mobility of steel line, resulting in deposition area, volume and height of the maximum and minimum fluctuation is obvious;

举例来说，1972年袭击了图瓦卢的飓风比比在东部礁岩上沉淀了140公顷的沉积碎屑，将主岛的面积扩大了10%。

For instance, when hurricane Bebe hit Tuvalu in 1972 it deposited 140 hectares of sedimentary debris onto the eastern reef, increasing the area of the main island by 10 per cent.

另外一个解释是，暂时沉积的水会结成大面积的薄冰，有助于风力的反射和集中，更容易推动石头前进。

Another explanation offered is that the temporary deposit of water, chilled to form extensive sheets of ice, might help to reflect and focus the winds, making it easier for the rocks to move.
