It finds that the sensitive port to ESD is CB junction and the sensitive parameter is V_(BRCEO) when the device damaged;and then the square-wave injection is adopted in t.

Second harmonic injection for restraining third-order intermodulation in traveling wave tube

In this paper,we propose two effective methods,namely the method of overmodulation and harmonic injection,to increase the voltage transfer ratio.

In order to compress the second harmonic and the third-order intermodulation, and improve the linear, harmonic injection is come up in twenty century 70s, but get detailed investigation recently along with the widely used computer simulation.

Sensorless control of salient - pole permanent magnet synchronous motor based on carrier signal injection;

This paper presents an approach to sensorless control of salient-pole permanent magnet synchronous machine (PMSM) using a high frequency carrier signal injection to estimate the rotor position at cow and zero speed.

4 oilfield and an investigation on literatures in China and abroad, the ECLIPSE100 software,a black oil model simulator,is used to make numerical simulation for several immiscible gas injection schemes.

This paper studies the factors including injection pattern, injection procedure and slug size which influence the displacement efficiency of loam flooding.

First, we had done the research on the injection pattern and measurement of viscoelasticity of the ternary compound systems with each kind of polymer, respectively, from which concluded that resistance factor and residual resistance factor increased as the increasing of the concentration of polymer, and so the viscoelasticity did.
