acoustic load

When the acoustic resistance of the load is fixed, oscillating frequency, heating temperature and input power to RC load will increase along with the increase of the length of the pressure amplifier in a certain range.

在负载的声阻固定的情况下，一定范围内振动频率、加热温度、负载入口声功随着压力放大器长度的增大而增大；

Under cycling loading, rock damage and AE events in unload phase is increasing more quickly than load phase with load increasing. The Y value of acoustic emission load/ unload ratio descending gradually.

随着载荷的增加，岩石在卸载过程中的损伤和声发射事件较加载过程增加更快，声发射数加卸载响应比Y值逐渐减低。

The Y value of acoustic emission load/ unload ratio descend to 1 when rock reach final elastic deformation can be seen as precursory characteristic for rock failure.

声发射数加卸载响应比在岩石弹性变形阶段后期下降到1，可以作为岩石失稳破坏的前兆。
