two-valley model

Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workplace health and safety issue.

几十年来过瘦模特一直是争论的焦点，两个研究人员称模特的体重应该是职业健康的安全问题。

Finally, according to a special ( IEEE 802.16) test channel model, the performance of two equalization algorithms LMS and RLS is simulated, and it is found that the RLS algorithm is superior to LMS algorithm.

最后分别就两种自适应均衡算法（LMS、RLS），结合一种具体IEEE802.16单载波调制系统推荐测试信道进行了仿真，得出RLS算法优于LMS的结论。
