Indeed, satellites can not only count such small bodies of water, they can measure their longevity, salinity and mud content-and thus how mosquito-friendly they are.

的确，卫星不仅可以计算这样小块的水，而且它们可以测量水池的寿命、盐浓度和泥含量——因此就可以测出它们被蚊子喜欢的程度。

When the content of water and temperature in the layers changes, the layers expand and contract and the measure mark of deformation is also moved.

当地层中水和温度的量值变化时，地层便膨胀或收缩，依附于地层的形变测量标志也就随之而被移动。
