A slim azimuth 20 independent-arm caliper logging tool;

Design of TFY-1 universal azimuth jointer with a restrained gyroscope;

The pit shaft parameters of the elevation angle,the azimuth angle,the tool of facial angle and so on are obtained after the computation.

Climate Orientation and Building Surface Energy Efficiency——Research on Building Surface s Climate Resources Utilization Technology Strategy;

Design of Orientation Sensor based on Fluxgate Technique;

Influence of Orientation of Wollaston Prism on Accuracy of Laser Interference Measuring System;

Distribution of Reflecting Energy Varying with Different Position of Cube-corner Prism;

In a measuring angle of laser interferometer,the different positions of the cube-corner prism make the range of the measuring angle of this instrument changed.

These regulations are explained in three aspects, respectively of space, position and shape, which form the basic architectural regulations.

Research of underwater passive target motion analysis algorithm using both bearing and time-delay measurements;

In this paper,the question of how to track underwater target using bearings and time-delay is presented and analyzed.

Qualitative Spatial Reasoning about Topology and Cardinal Direction;

In this paper,we study three groups of direction discourse in Peotry,they are"left and right","four direction"and"south mountain".

Subjects read narratives describing directions of objects around an upright observer, who was periodically reoriented, and given a description of the objects in different positions around his body.
