Simulation results show that compared with clipping and the traditional companding techniques, threshold-based companding scheme can effectively improve the performance of PAPR with low complexity.

仿真结果表明，与削波技术和传统的压扩技术相比，门限压扩以较小的系统复杂度获得了峰均比性能的改善。

As filter Banks are used to simulate the contrast sensitivity function (CSF) in these models, the complexity of visual threshold obtainment and real-time (assessment) algorithms are increased.

由于这些模型采用滤波器组模拟对比度敏感函数(CSF)，增加了视觉阈值获取和实时评价算法的复杂度。

The second experiment found 17.27 minute was the threshold of comfort viewing, and the complexity of background and Chinese Characters (or not) didn't affect the threshold.

实验二的结果显示，17.27分是视力正常被试能够不费力看清宋体汉字细节的视角，且背景复杂度和（非）汉字对舒适角度大小无显著影响。

The second alarming point is that when the complexity of a system reaches its corresponding critical threshold (critical complexity) the system in question becomes very fragile and therefore vulnerable.
