The researchers first made a patterned template containing holes that were just tens of nanometres deep. They then coated the template with ink made of flecks of gold just 60 nanometres in diameter suspended in an aqueous solution. The ink was kept deliberately thin and exposed to air at a precisely controlled temperature, which concentrated the gold particles at the curved upper surface of the fluid. As the liquid evaporated, the ink became richer in gold, the fluid flowed over the holes, and a single nanoparticle of gold dropped into each one.

随着液体的蒸发，墨水的含金量也就随着增多，而当流体流过模板上的小孔时，一个单一的黄金纳米颗粒就会进入小孔内。
In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it.
相反，上面的液体表面蒸气变成密集的蒸发分子加入其中。
At this point, as freon heater heating, so that the partial liquid again evaporated into gas, then re-entering the latter part of the interior heat exchanger.
此时经氟利昂加热器的加热，使该部分液体再次蒸发成气体，然后再进入室内换热器的后半部分。
