The excellent agreements between simulated and measured results prove the accuracy of the established circuit model. Moreover, the varactor was added to the resonator to adjust its resonant frequency. As expected, the reactance introduced by the varactor indeed affects the net inductance and capacitance obviously. It is noted that, not only the shift with the center frequency, the inductive or capacitive of the reactance can also provide a parameter to switch its frequency toward the two directions away from the one without varactor. As a consequence, a wideband tunable band-pass filter is achieved. Although the bad quality factor with the diode strongly increases the insertion loss, this concept was proved to be available for effectively tuning the center frequency of such a class of band-pass filter.
另外,在共振器上的varactor是用来调整共振器的共振频率,如预期的,由varactor所造成的电抗确实的影响到共振器的总电感和电容值,值得一提的是,不仅滤波器的中心频率可以被改变,这电抗是电感性或是电容性也将决定滤波器的中心频率将大於或小於未加varactor时滤波器的中心频率,利用这个结果,我们也实现了一个宽的可调频率带通滤波器,虽然不理想之二极体的Q值增加了滤波器的介入损失,但这原理是被证明可有效的用於调变带通滤波器的中心频率。

The higher surface energy of substrate results in higher effective viscosity and thicker ordered molecular film.
从侧面证明了有序液体模型的正确性,即薄膜润滑的成膜性能与近固体表面润滑剂分子的有序度密切相关;足够大的外电压使无序流体膜有序化,生成较高的有效粘度和较厚的油膜,并且二者随着外电压的增加,逐渐趋于稳定;外电场作用下,摩擦系数增大,切断电源后,摩擦系数减小,但不能恢复到未加电压前的摩擦系数值。
