Based on the above, the impact of amplitudecoefficient ratio on amplitude-phase Double Differential Space-Time Codes is discussed, and an optimal selection scheme in amplitudecoefficient is given.
在此基础上，讨论了幅度系数比对幅度相位双差分空时码的影响，并给出了一种最佳的幅度系数选择方案。

Amplitude modulation coefficient is a parameter, by which the capacity of internal force redistribution in continuous composite beams is reflected.
弯矩调幅系数是反映连续组合梁内力重分布能力的参数。
