| 摘 要： | 电阻应变计通过应变过渡区传递应变到敏感栅丝，而此过渡区的范围大小与所测结构的应变有关，使得电阻应变计的灵敏系数发生变化，而非通常测量中使用的常数灵敏系数。本文讨论了灵敏系数变化对测量结果造成的误差，并给出了降低此影响的方法。

| Abstract: | 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. This issue analyzes the test aberration due to the variations of the sensitivity coefficient, and offers some methods to reduce its influence. |
