monotonic curve meaning in Chinese

单调曲线

The fabrication of specimens , the program and phenomenon of the experiment are described in detail , and the phenomenon of the experiment is interpreted also . experimental hysteretic curves are compared with calculation results utilizing integral method , and agree well . the effects of these parameters on hysteretic behaviors , monotonic curves , elastic rigidity and ductility are analyzed according to p - a monotonic curve from the experiment
文中具体地介绍了试件的制作，试验过程以及试验现象；详细分析了试验现象；将试验所得的p -滞回曲线与数值计算结果进行比较，吻合良好；通过包络线分析各参数对构件滞回性能、单调曲线形状、弹性刚度、延性等的影响。
