摘　　要：提出一种新颖的基于双恒流源法六端比例测量原理的应变测量自动调零与自动校准技术,介绍了其实现原理。测试及实际离心载荷试验运行表明,测量精度高,稳定性、抗干扰性和可靠性好,在工程应用中具有很好的实用价值。In this paper, auto - balance adjusting and auto - calibration technology for a novel high - accuracy strain measuring technology based on the method of dual invariable - current, six end connecting and proportional measurement are proposed. The principles of implementation are described in detail Lab test and practical centrifugal load experimentation indicate that accuracy, stability, anti - influence and reliability are excellent. The auto - balance adjusting and auto - calibration technology are worthwhile in practical engineering applications.
