Trace amounts of molybdenum in water and soil extract samples were determined using a dual column on-line ion-exchange preconcentration FIA-ICP system.
本文采用双柱在线离子交换预浓缩FIA-ICP系统，建立了水及土壤浸出液中痕量钼的测定方法。
But not only is there more ice than anyone suspected, it's also in a form - small crystals mixed with crumbly soil - that make it easier to extract than if it were in massive deposits.
但是不止是那里有比预想更多的冰，冰的形式也出人意料，即团块状土壤中混杂的小晶体，这使得当它们大量存在时更易提取。
To extract it would require digging up much of the moon's upper few feet of soil and baking the soil to release the solar wind-implanted gases.
为了提取它需要挖起大部分的月球表层几英尺的土壤并且烘烤土壤释放出太阳风注入的气体。
