This paper presents an adaptive scheme that USES both frequency and rate-of-change of frequency measurements to dynamically set ULFS relays if more than one generation outage is experienced.

介绍一种自适应型低频减载装置的方案，它依据频率和频率的变化率，动态的确定减负荷装置的动作情况。

The non-linearity increases with the increase of the frequency change rate, which does not depend on the thickness of the resonant beam.

频率相对变化量与梁的厚度无关，增加频率的相对变化量也同时增加了输出信号的非线性度。

The results show that the deposit rate, composition and properties of coating change with the variation of duty ratio and pulse frequency.

结果表明，镀层的沉积速率、镀层成分及镀层的性能都随脉冲频率和占空比的变化而变化；
