摘要
收敛计恒张力控制精度是直接影响测量精度的主要因素，通过理论计算与测量精度分析，为确定收敛计恒张力参数提供了可靠的依据，且提出了提高收敛计测量精度的主要技术途径。
The precision of tape- extensometer′ s constant tension is the main factor to affect measure precision. Through theoretical calculation and measure precision,it provides a reliable basis to determine the parameter of tape- exten- someter’ s constant tension.Lastly,a technical approach to advance tape- extensometer's measure precision is pointed out.
