光行差

The specific research contents include: celestial coordinates The establishment of the Department; Sunday apparent motion of celestial bodies and the anniversary of the apparent motion; celestial parallax, atmospheric refraction, optical aberration, precession, nutation theory and applications; astronomical time measurement principles and time systems; depending on the location of celestial bodies return calculation methods.

具体的研究内容有：天球坐标系的建立；天体的周日视运动和周年视运动；天体的视差、大气折射、光行差、岁差、章动的理论及应用；天文时间计量的原则和时间系统的建立；天体视位置的归算方法等。

Aberration and retardation effects are also taken into account when calculating pulse phase, colatitude angle and position angle.

在计算辐射的相位、余纬角和偏振位置角过程中考虑了光行差效应和延迟效应。

Full quanta theory was used in analysis the working principle of laser, educed the photon states of single pattern radiate in two energy-step system, and simulated the establishment of laser mode and statistical distribute of photon.According to elf consistent equations of RLG; build the simulated program with LabWindows/CVI and do some simulation experiments,The result of simulation matched the theory perfect perfectly and conform to the experiments, the locked-in and pattern competition coursed the periodic light intensity.

在激光陀螺自洽场方程组的基础上，运用LabWindows/CVI软件建立了灵活方便的激光陀螺仿真平台，并进行仿真试验，仿真试验结果与理论分析很好的相符合，且能够较好地说明陀螺试验现象，即在闭锁阈值附近，由于闭锁效应和模竞争相互影响，使得激光腔中两行波相互关联，光强差随时间呈周期性变化。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
