NL：负大

“Negative Large”在学术和科学领域，尤其是数学相关文献中，常被缩写为“NL”，以提升书写和使用的效率。它对应的中文含义是“负大”，通常用来描述一个数值或变量在数轴上趋向于负无穷大的情况。这种简写方式既简洁又便于交流，是专业术语中常见的表达习惯。

Numerical results show that the group velocities of the second and fourth branches are negative at large wavelength region and only the phase velocity of the second branch approaches the Rayleigh wave speed at the short wavelength region.
计算结果表明，在长波区域，第二和第四分支的群速度小于零；在短波区域，只有第二分支的相速度趋近于Rayleigh波的波速。
