niti-sma meaning in Chinese

镍钛形状记忆合金

2 ) based on the method of hysteresis element , the a - e relation of niti - sma has been obtained for tensile tests , and numerical simulations are in good agreement with experimental results
2 )基于滞后元方法，对niti合金的拉伸-关系进行表征，建立了物理模型，并将数值模拟结果与实验结果相比较，两者吻合较好。
The novel researches done in this dissertation include : 1 ) experimental methods for niti - sma are proposed based on the sma material evaluation technology and requirement of adaptive structures , and experiments on niti wires have been performed
本文主要创新点： 1 )对niti合金性能进行了系统的实验研究，得出了一些有价值的结果。
