This circuit is more simple, convenient connectivity, the choice of its parameters with the speaker impedance has a direct relationship, and the speaker impedance is a function of frequency, with larger deviation from the nominal value, so the error is also large, is not conducive to adjust.

此电路较为简单，连接方便，它参数的选择与扬声器阻抗有直接的关系，而扬声器的阻抗又是频率的函数，与标称值偏离较大，因此误差也大，不利于调整。

Fault condition includes the descent of cable force, sinkage of bridge tower and structure change of the main girder. Data recorded are cable force, girder stress, girder linetype, frequency response function, mode shape and etc.

其中损伤的形式有索力下降、主梁局部刚度变化以及桥塔不均匀沉降等，监测的参数主要有拉索索力、桥面线型、主梁应变等静态参数以及主梁固有频率、频响函数和振型等动态参数。

It is a new tool to detect and observe the structure and status of underground media by accurately measuring its transfer function through sinusoidal elastic wave accurately controlled in frequency and stable in phase.

它是使用一种精密控制频率和相位稳定的弹性波，对发射和接收两点间的传递函数进行精密测定从而监视和观测地下构造和状态的一种新型手段。

While for the sinusoidal approximation method, a detail derivation of the amplitude of each sinusoidal function is re-derived for completeness.

为完整性，文中亦详细推导正弦函数近似法中各个频率之振幅。

Finally, applying the current basis function of three-term sinusoidal expansion, the radiation characteristic and input impedance of the vertical and horizontal antennas above lossy ground are analyzed by the method of moments with the variation of frequency, height from the ground and ground parameters.
