Advanced portable and dynamic parameter test system for vehicles;

Quasi-dynamic measurement technology for grain moisture content based on DSP and MPU;

Taking natural frequency and motion track of the Shale Shaker as the examples,the application of VI based on VIC in dynamic measurement of Shale Shaker is given at last.

The gas sensing behavior of a single SnO_2 sensor was investigated in detecting carbon monoxide gas based on a dynamic measurement method in which temperature was modulated by heating waveform and frequency.

JZD-1 locomotive dynamic detection system;

Dynamic detection for the height of contact wire;

A new dynamic detection technique for locomotive bearings;

Data collecting design of pilling foundation dynamic testing system based on USB2.0;

On the basis of the requirement of dynamic testing for a airborne optoelectric platform,the tracking errors and acquiring characteristics of the airbome optoelectric platform were tested simulatively in a lab and the possibility of application of new deigned equipment to dynamic testing was analyzed.
