ccw怎么记

the cw and ccw light which propagate in the imperfect single-mode fiber in fiber-optic depolarized gyro must generate a nonreciprocal phase error associated with magnetic field, because of faraday effect, when the magnetic field is perpendicular to the fiber loop surface.

去偏光纤陀螺的非理想单模光纤，在垂直于光纤环面的轴向磁场作用下，由于Faraday效应，在其中传播的正反两束光会产生一个与磁场有关的非互易相位差。

the second and third stages of magmatism occurred before the main orogenic episodes in the end of mid-jurassic and late-jurassic, respectively; therefore, the main orogenic episodes have counterclockwise ( ccw) p-t-t path.

其中，第二、三岩浆活动阶段分别早于燕山造山带在中、晚侏罗世末的两次主造山幕发生的时代，所以燕山地区主造山幕的P-T-t演化为逆时针轨迹。

the electrical activity in surface ecg closely correlates with conduction in specific parts of the atria in ccw-afl, but it is not a frequent phenomenon in cw-afl.

CCW-AFL时FL波与心房内特定部位激动时间有一定对应关系，但在CW-AFL时这种对应关系并不常见。
