In this paper,the lemma on the logarithmic derivative of meromorphic functions in annulus is extended and the Milloux′s inequality of meromorphic functions of annulus is obtained.

In the scientific researches, the basic theories on the real logarithmic derivative and the logarithmic integral are established.

It is known that the model of the universal Teichmüller space by the logarithmic derivatives is the union of infinite many disconnected components.

Also we estimate the pre-Schwarzian derivative inner radius of univalency for the exterior of the triangle.

According to the actual demand of digital guidance for tracking telemetry and control (TT&C) equipment in missile flight test, functions and implement principle based on digital UNIX platform of digital guidance are introduced in this paper.

On the basis of introducing functions and implementing principles of the real-time digital guidance, adopting the key technology of variance statistic algorithms compared with accuracy and MATLAB platform, the central computer real-time digital guidance is analyzed.

A method used for disposing the theodolite′s guidance data is presented The method fuses guidance data by means of the algorithm of parameter estimation In this way it will make up for shortage of traditional method The disposition of the theodolite′s guidance data is carried out The results show that the theodolite′s guidance accuracy can be obviously improved Its guide errors is less than 0 50

The realtime guidance data which is produced by dynamic target is provided for testing external lead function of photoelectric theodolite,according to the need of indoor checking and testing of the dynamic characteristic of theodolite s tracking system.
