Study on thermal explosion delay time of NiAl(Fe) system;

Also,this paper suggests the curves of the real and imaginary parts of the first three order dimensionless complex frequencies varying with dimensionless flow speed in the case of different dimensionless delay times and mass ratio and obtain the range of dimensionless speed of the occurrence of divergence instability and coupled-mode flutter of the cylinde.

The effect of dimensionless delay time of the viscoelastic material on the curves between dimensionless flow velocity, and real and imaginary components of dimensionless complex frequencies of the pipe conveying fluid in the first two modes are also analyzed.

In this paper,a novel method for the analysis of switching time and dynamic be- havior of the electrostatic driven RF MEMS capacitive switches applied to microwave distributed MEMS phase shifters is presented.

The calculated switching times for typical MEMS shunt switches are about 1～40μs,depending on the thickness of the membrane,cons.

Focused on the resistance device\'s opening time of the one-dimensional trajectory correction projectiles was difficultly determined and the calculation time was long,find out the relationship berween the resistance device\'s opening time and the correct distance,to found the algorithm model for determine the resistance device\'s opening time.

This paper analyses and describes opening time of a large flow safty valve for the hyolraulic roof support,sinking speed of coal bed roof and relationship among support parameters.
