Research on event-related functional magnetic resonance imaging of motor preparation and execution;

Purpose:To study the deaf and normal brain response various stimulus frequency rates using event related functional magnetic resonance imaging (ER fMRI), and to describe the rules of response and find the best stimulus frequency rate.

The occurrence of event related fMRI is a revolutionary progress.

Aiming at RFID-related application characteristics,a composite subscription language was designed,the composition and use of subscription language were studied,and a matching algorithm for detecting composite events was proposed based on the time event,matching graph of composite subscription as well as con.

Uniaxial ratcheting of SiC_P/6061Al alloy composites and its time-dependence at high temperature;

A series of experiments were carried out to observe the cyclic deformation behaviors of LY12CZ aluminium alloy and its time-dependences at room and high temperatures.

It is shown that the ratcheting behavior of the composites is similar to that of the un-reinforced matrix in macro-scale,namely,the ratcheting also occurs in the composites under asymmetrical stress cycling,and the ratcheting strain increases as the stress amplitude and mean stress increase;the ratcheting has great time-dependence,i.
