A new lithology identification method based on axial amplitude modulation signal of drill string is proposed. 提出了一种利用钻柱轴向振动调幅信号实现岩性识别的方法。
We add amplitude modulation onto the CW laser and measure the modulation amplification between seeding and output laser. 我们对注入的连续波激光进行幅度调制(AM)并且测量了输入输出光之间调制信号的放大倍数。
This system of modifying the carrier waves is called " Amplitude Modulation(AM)," or " AM ". 这个改变载波的系统称为振幅调制或缩写为AM。
