查询词典 inductive reactance

By adjusting the trigger angle of thyristor, TCSC can regulate the reactance from capacitive to inductive mode continuously.

TCSC通过调节晶闸管的触发角，可以实现电抗值从容性到感性的较大范围内连续调节，不仅可以控制系统的潮流分布、阻尼低频振荡，而且还可提高系统的稳定性。

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。

Experimental checks are made, Two types of circuit s are studied, the inductive and the capacitive reactance-tube circuit s.

本文即就两种基本调频电路，作理论之推引，得出两个基本方程式，表明其间之关系，并佐以实验之证明。

This simple definition ignores the fact that amplifier output impedance usually varies considerably across the audio band, increasing with frequency as the negative feedback factor falls; this indicates that the output resistance is actually more like an inductive reactance.

这个简单的定义忽略了功放输出阻抗通常是随着音频带而变化，负反馈因素降低的时候频率也增加这一事实。这就意味着输出电阻实际上更像是一个电感电抗。

This situation occurs because noise cancellation depends on the fact that the inductive reactance of the windings must be much larger than the impedance of the cable.

线圈的感应电抗必须远大于电缆阻抗，噪声抵消导致这个情形出现。

R where f = the frequency, Hz; L = the inductance, H; R = the dc resistance, X; and XL = the inductive reactance of the coil.

其中f =频率，赫兹；为L =电感艇与r =直流电阻，第十章；和XL =感应电抗线圈

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
