Strain Transmit Research and Aberration Analysis of Electric Resistance Strain Gauge

The strain transmits to the sensitive grid through a transition area whose range is related to the test strain,which introduces variations to the sensitivity coefficient of the electric resistance strain gauge instead if a commonly considered constant.The test aberration is analyzed due to the variations of the sensitivity coefficient,and offers some methods to reduce its influence.
