To improve the pointing accuracy of the telescope mount and the capability of daylight tracking, it is necessary to do more study on the error of telescope axes. The present thesis analyses many kinds of factors that cause the pointing error of telescope mount, and discusses the method for correcting the pointing error by setting up telescope mount model in detail.

本文详细分析了望远镜机架指向产生偏差的各种因素，讨论了通过建立望远镜机架指向误差模型的方法来修正望远镜机架指向误差的方法，通过使用CCD观测恒星来求解望远镜机架指向误差模型参数。

GPS surveying based on GPS reference station network can improve the reliability and veracity, eliminate and weaken the infection of atmosphere error and orbit error which is relative to time and space in the observation of GPS surveying, which makes the rapid static pointing and RTK dynamic pointing of medium and long distance into reality, and has virtues of acquirable WGS84 coordinate directly.

采用基于GPS基准网的GPS测量可以提高GPS测量的可靠性和准确性，可以消除和减小GPS测量观测值中与时间和空间相关的大气误差和轨道误差的影响，使中、长距离快速静态定位和RTK动态定位成为现实，还具有可直接得到WGS84Z坐标等优点。

In the intersatellite coherent optical communication, the vibration of a satellite will lead to a pointing error of transmitting and receiving antennas, which will decrease the signal-to-noise ratio and increase the bit error rate. In this paper, the Rayleigh distribution is taken as the pointing error model caused by satellite vibration, and PSK homodyne communication scheme is used as an example to analyze the influence of the satellite vibration on the system instantaneous BER and average BER. The simulation calculation result of BER is given.

针对星间相干激光通信中卫星平台的振动造成发射天线和接收天线的瞄准角误差，使系统信号信噪比下降，误码率增加，该文以瑞利分布作为振动造成的瞄准角误差模型，结合高斯本振光和艾里信号光外差检测模型，以PSK零差通信体制为例分析卫星振动对系统的瞬时误码率和平均误码率的影响，给出误码率仿真计算结果。

In this paper, the theoretical expression of addition pointing error based on an optical path is derived and the effect of the misalignment of the spheric centers on inside and outside surfaces on the pointing accuracy of a sight axis is analyzed.

本文根据光路图推导出了产生这种误差的数学表达式，分析了内外球心偏离对视轴指向精度的影响，进行了相关实验并对实验数据进行处理。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
