Active control with absolute acceleration feedback;

It is showed by analytical result that the basic reason of these problems is caused by absolute acceleration′s mutation of mechanism.

Dynamic characteristics of ATMD control are discussed in two complete-feedback modes based on absolute acceleration of the structure and ATMD (Because,in fact,the acceleration sensor detects the absolute acceleration).

Using the documentary datum and comparative method, the author studies some technology factors of Chinese-foreign long jumpers at the absolute speed, run-up speed, rate of the speed usage, take-off ability, etc, and analyses the existing diversity, based of these, the author makes some proposal for solving questions and increasing achievement.

A query algorithm with a high absolute speed costing low I/O based on set theory is given, and a query algorithm of high response speed based on parallel process is presented.

The paper expounds briefly the absolute speed of ru n -up rhythm etc ,and attempts to improve sportsmen s long jump marks.

This paper discusses how the dynamic points and the dynamic reference system are selscted in composite movement and how the relative motion paths influence the computational points absolute velocity and absolute acceleration.

It was found that apart from his absolute velocity obviously lower than his opponents’, Huang Geng s velocity of the last 10m run up was also lower because of the influence of the absolute velocity.

We obtain the absolute acceleration response spectrum,then a new attenuation relationship,which is between the small and moderate earthquakes on bedrock site in Fujian region,is given.
