查询词典 concave curve

The maxima of low-temperature internal friction peaks plot a symmetrical peak-like curve at logarithmic frequency spectrum and the peak-like curve shifts toward high frequencies with the increase of heating rate, indicating that phase transition relaxation time decreases; the maxima of high-temperature internal friction peaks exhibit a linear relation to the reciprocal frequencies, and as the heating rate increases its slope rises, which implies that the heating rate drives the normal movement of phase interface further in low-frequency measurements.

低温内耗峰峰值与对数频率呈现峰形函数关系，随升温速率的增加，频率峰向高频方向移动，相变弛豫时间减小；高温内耗峰峰值与倒数频率成直线关系，随升温速率的增加，直线斜率变大，表明低频测量时升温速率对相界面法向运动的驱动作用更强。
