When the component (501) is on a printed circuit (500) and passed through a reflow operation, the adhesive melts forming a physicalbond between the component (501) and the printed circuit (500).
What the researchers observed, they reported online in the Journal of Physical Chemistry b, is that water molecules bond with one another in a surprisingly complex and dynamic way.
研究者曾在物理化学期刊b (The Journal of Physical Chemistry B)在线公布他们观察到的现象:水分子与其他水分子以一种令人惊讶的复杂动态的方式结合。
