| 1. | It consists of three parts : accurately controlled signal source , time signal stacker and " sompi " cepstrum method
它包括三部分：精密可控震源、信号叠加器和“存否”倒谱方法。 |
| 2. | When using a line feed , telescope operators produce a unified signal by adding up the different parts of the signal , but the results are never as strong and clear as they are with a parabolic dish
使用线形馈源时，操作者产生一个标准信号叠加到信号的不同部分，但是结果从不会像使用抛物面碟面得到的那样强大、清晰。 |
| 3. | If the message is encoded into the total intensity , the transmission method that works quite well in single - mode laser system cannot be extended directly to the multi - mode laser system due to the delay effect of the transmitted message
当把信号叠加在总强度上时，由于信号有延迟效应，所以用原来在单模激光之间传输信号的成功办法就出现了问题。 |
| 4. | It produces the i and q signals , limits their pass bands , uses them to modulate the subcarrier in a quadrature and adds the moduled subcarrier to the luminance y , blanking and synchronizing signal waveform
它首先分离出i信号和q信号，指定了它们的传输频带，并用它们对副载波进行正交调制，然后将调制过的副载波信号叠加到亮度信号y和同步信号波形上。 |
| 5. | When the transmitted message is encoded into the intensity of each mode in a multi - mode laser system , it is possible to achieve multi - signal and multi - channel communication due to the chaotic synchronization of the total intensity is based on the synchronization between each corresponding mode
当把信号叠加在多模激光中每一个模式的强度上时，由于多模激光之间总强度的混沌同步是建立在每个对应模式的强度的混沌同步的基础上，所以这就给利用每一个模式的强度进行多通道信号传输带来可能。 |
| 6. | One method is that the message is encoded into the total intensity output of the multi - mode transmitter laser . the other is that the transmitted message is encoded into the each mode intensity of the multi - mode transmitter laser . then the multi - channel communication between two identical multi - mode chaotic lasers can be achieved
在多模激光的混沌同步通讯中，通常有两种方法，一种是把信号叠加在多模激光的总强度上，另外一种是把信号叠加在多模激光中每一个模式的强度上，从而实现两台多模激光之间的多通道信号传输。 |
| 7. | The accurately controlled signal source generates sinusoidal elastic wave accurately controlled in frequency and stable in phase to " illustrate " underground media . time signal stacker receive signal by stacking and doing fft to measure the transfer function of media . " sompi " cepstrum method retrieve group velocity travel times and decayed factors of wave element from observational data of transfer function in a limited frequency window
精密可控震源用于产生频率精确相位稳定的正弦弹性波以照射地层内部，信号叠加器通过对接收信号进行叠加和进行傅立叶变换的方式实现对介质传递函数的精密测量， “存否”倒谱方法能够根据一段窄带频域传递函数数据获得时域上各个波成分的群速度传播时间和介质衰减因子。 |
