| 摘 要： | 近二十年来,由于超声波设备的普及,超声波在化学中得到广泛的应用.声化学也于80年代被科学界承认是一门与光化学、热化学、高压化学等地位相当的新兴交叉学科1] ,超声波对化学反应的影响目前被认为是来自其声空化作用2].所谓空化作用是指在超声波作用下,液体中空气泡的快速形成和突然崩溃的过程,在这瞬间,在空气泡周围极小的空间能产生5000K以上的高温3]和约5×107Pa的高压4],产生高速射流5],使得在普通条件下难以发生的化学反应有可能实现.

| Abstract: | To prepare the adherent and high active platinum black plated titanium electrode,ultrasonic agitation technology was adopted during the electrodeposition.Ultrasonic agitation technology enhanced the activity of electrode,improved the cohesion between coatings and substrate,changed the microscopical surface shape and increased the real surface area of electrode.The enhancement of the activity of electrode was in large due to the electrode rugosity. |
