This proves that the idea of separating different building components with different material frequency works.
这也充分证明了不同的建筑材料组成不同的分离式的建筑元素是很可行的。
As the doohickey hummed away at a very high frequency-a whopping 6 billion cycles per second-the "piezoelectric" material in it produced a warbling electric field that was easy to detect.
当这个小装置以每秒60亿周的高频速度振荡时，它表面的“压电”材料会产生一个很容易被检测到的振动电场。
With high frequency, it is suitable for some metal material marking in high speed.
激光频率高，更适合一些金属材料的打标，打标速度更快。
