声软化现象是发现于矿物岩石等材料中的现象，表现为在恒定的压力下（包括常压）升温，其弹性波速度在某一点上开始突然下降，这一点的温度称为物质的软化点温度。该现象的特征是：软化点温度明显低于物质在相同压力下的固相线温度；有些物质中软化点温度随着实验压力的不... Acoustic softening phenomenon is found in mineral rock and other materials phenomena, manifested as constant pressure (including atmospheric pressure), the elastic wave velocity at a certain point began to suddenly decline, the temperature at this point is called the softening point of the material temperature. The phenomenon is characterized by: the softening point temperature was significantly lower than the substance under the same pressure in the solidus temperature; some softening point temperature with the experimental pressure is not ...
