Numerical results show that the acoustic radiation power of the plate is effectively reduced by the optimized additive mass loading.

In this paper, the additive mass technique is also proposed for correcting the truncation error of higher order modes without using the residual compliance matrix.

本文还提出了一种附加质量法来修正高阶模态的截尾误差而不采用剩余柔度矩阵，从而使本法能简易地获得高精度。

The sign reversal applies only to quantum numbers (properties) which are additive, such as charge, and not to mass, for example.

举例来说正负号只适用于附加量子数，例如电荷，而不是质量。
