phase lag

And the relation among the tidal parameters, such as tide factor and phase lag, as well as the lithology and the conditions of the boreholes is discussed in this paper.

同时，讨论了潮汐因子、相位滞后等参数与岩性及井孔条件的关系。

For the control action it's an adaptive PID controller without any phase lag, but there is an amplifier in the high frequency, an integrator in the low frequency, and a PID only in the medium frequency.

对控制信号而言，它是一个没有任何相位落后的PID控制器，R高频为一放大器，低频为积分器，中频段为PID。

Rom the analysis of solid tide recorded in Chuxiong seismic station, it is discovered that the reduction of 3-4 months for tide phase lag appears before earthquake.

根据楚雄台倾斜固体潮潮汐分析的结果，发现地震前潮汐相位滞后出现3&4个月的短期减小。

With the simulated cotidal chart of M2 tidal constituent, the distributing characteristics of the amplitude and the phase lag of M2 in the sea region near Zhanjiang are revealed.

根据模拟结果绘制的M2分潮的同潮图，揭示了湛江附近海域M2分潮振幅和迟角的分布特征以及M2分潮的传播和发展规律。

The results show that the parameters have no obvious differences between digital observation data and analogue observation in data form, observation precision, variance, median error of tidal factor and phase lag.

结果表明：①溧阳台数字化观测和模拟观测资料的形态、观测精度、方差、潮汐因子中误差、相位滞后等参数无显著差异；

Three main influence factors of the phase lag property were discovered.

得到了相位滞后的3个主要影响因素；
