The dynamic gate trigger voltage critical fall time for triggering CMOS latch effect under different supply voltage was tested by changing the output capacitor load and fitted the critical fall time under 0 pF output capacitor load.

This paper puts forward the thought to recognize the radar emitter by means of rising/falling edge of radar pulse signal.

Study of critical gradient of piping for various grain sizes in sandy gravels

According to the flume tests and basic theovetical analysis, several important formulas describing nonuniform muddy flow transportation,such as nondepositing velocity,critical gradient and ditch phase factors are deduced.

A brief analysis is carried out on the resulting conditions of sand gravel seepage deformation, on this basis, the modes of seepage deformation are assessed briefly and the calculation method of critical gradient for seepage deformation is presented.

Based on the full hydrodynamic model,a new approach is proposed to calculate the distributed threshold rainfall for flash flooding,which constitutes the basis for effective flash flooding warning.

Based on the simulating results,we analyses the influence of the bias circuit of power amplifier on the rise time and fall time of pulse.
