查询词典 input signal

The main causes of the vibration in pipeline system are in two respects : The first is the vibrant force of the medium acted on pipeline system,i.e.exciting signal,such as the vibrant force caused by the gas flow at the compressor ′ s inlet and outlet and at the ramified and nodel points as well as the action of pig passing through pipeline bridge,etc.;The second is the response to the exciting signal,which is relating to the characteristics of the pipeline system,i.e.the rigidity,support,quality and equipments of the system besides the waveform of the exciting signal.

管道系统振动的原因主要有两方面，一是介质对管道系统产生的振动力，即激发信号，如气流在压缩机进、出口，分支节点部位产生的振动力，清管器通过管桥时对它的作用等；另一方面是对激发信号的响应，其响应除了和激发信号的波形有关外，还和管道系统本身的特征，即系统的刚度及支撑，质量及其配置等情况有关。

Through the interferencing light intensity under a sine-wave modulation signal analysis, the output signal of fiber-optic gyroscope is demodulated. And then the change of the output signal of gyro is gotten. Through the analysis of the change we know that the effect of residuary intensity modulation on the performance of Interferometric Fiber Optic Gyroscope is related with the precision and accuracy requirements of IFOG. The higher precision, the more obvious effect.
