1) Double wave speeds
双速度
1.
Double wave speeds analyse for low-strain foundation pile integrity test;
桩基低应变完整性测试的双速度分析
2) dual rate-loop
双速度环
1.
For the lack of single rate-loop servo control composed of rate gyro of two-dimensional observation instrument stabilized platform,a dual rate-loop cascade control structure was presented,the DC tachometer was used to constitute the analog inner loop,and the rate gyro was used to constitute the digital outer loop.
针对二维观瞄仪稳定平台采用由速率陀螺构成的单速度环伺服控制的不足,提出了采用以直流测速机为测量反馈元件构成模拟内环,利用陀螺的"空间测速机"功能组成数字稳定外环的双速度环串级控制结构。
