Research on transverse sensitivity of the piezoelectric accelerometers;

The transverse sensitivity of piezoelectric accelerometers was studyed for a long time, a great deal of the calibrated datas were analysed and contransted.

With the enhancement of modern weaponry s hit precision,the transverse output error of accelerometer brings about an effect to inertial navigation system,so study the accelerometer transverse sensitivity can enhance the weaponry s navigation accuracy.

Sensitivity coefficient in measurement uncertainty components of surveying instruments;

It intends to clarify the variation rule of NCF by calculating sensitivity coefficient of project NCF from operating activities,thus providing evidence to the c.

However, it s necessary in advance to obtain the sensitivity coefficient of magnetic measurement.

Results show that the resistance of carbon fiber increases during the tensile test,the gauge factor(fractional change in resistance per unit strain) of continuous carbon fiber monofilament is 1.

The sensitive characteristics of the Ru-based resistor for thick-film piezoresistive sensor is summarized and how to increase the gauge factor is discussed.

This paper has put forward a proposition that the sensitive coefficient is equal to the ratio between the standard deviation of sendout and the standard deviation of input value,and we have proved it to be true by mathematic logic.
