在仪器标定中, 测试设备的稳定性直接关系整个测试结果是否准确可靠, 因此仪器的稳定性指标对测试系统而言是相当关键和重要的.针对实验中由测试系统对应变敏感元件的压力所产生的电压不稳定性及时进行分析，并对常见的几种影响系统稳定性的因素做了介绍，重点对如何改善与提高系统稳定性的方法进行了分析.

In the process of instrument demarcating, the stability of test system is directly connected with whether the whole test result is correct and reliable. Therefore, the stability of instrument is quite crucial and important for the test system. The instability caused by sense organ of the library system was analyzed in time, and several common factors influencing on the stability of the system were introduced, but the way to improve and increase the stability of the system was mainly analyzed.
