1、The attenuation of the sound waves leads to a negative exponent pressure gradient.───随着波长的增大或介质黏度的减小，声波的衰减减缓，压力梯度越小。
2、The experiment showed that in the melon slices there were some points where the sound pressure attenuation coefficient were negative value or zero.───实验表明额隆内有若干点声衰减为负值及零值、意味着声波沿这些点传输时、声压非但不减小反而增大了。
