For avoiding confusion, the vibration period of simple pendulum is discussed in two levels, first, the resultant forces of equilibium poison and equilibium state in the intertialess reference system are obtained, then, teh differential equation of simple pendulum is given and the period is obtained in the inertial reference system by "space transformation".

The author analyzes two kinds of the transformation models which can convert the location result of GPS to the plane coordinate,the models are the plane transform mode and the space transformation mode,compares their conversion accuracy through the examples,and draws a beneficial conclusion,so as to extend the application of the technology.

These techniques help students improve their modeling techniques by observing and analyzing in reality,as to build up the capability of space transforming and total analyzing;while the practice will lead the students to form three-dimensional concept and be aware of creating space model between object and space,bulk and weight as well.

This paper combines the exterior criticism with the textural criticism and tries to organize the text as a comprehensive solid structure from the perspective of female space transforming.

Focusing on the dynamic derivation of the Wh-questions from narratives between English and Korean,the paper studies the issue in the relation between wh-substitution rule and the transformation space.

Therefore′ this paper proposes a new method based on basis space transformation to solve ear pose problem.

To decrease number of samples for the implementation of color space transformation, a method for modeling the chromatic characterization of video cameras was proposed.

Error study on color space conversion using Taylor's theorem

In color management process,the color space conversion is necessary.

A modified model of color space conversion is presented based on analyzing the color rendering principle of scanning object and the causes of color error.
