Her next project , trial and error 1997 , surfaced briefly before disappearing with nary a trace , but the subsequent mighty joe young 1998 netted theron more positive notices . her ascent was confirmed with her casting in celebrity , woody allen s 1998 cameo - fest that also featured turns from everyone from kenneth branagh to winona ryder to leonardo dicaprio to isaac mizrahi . in her portrayal of a perpetually aroused supermodel , theron shone in a role seemingly designed to allow her to flaunt her natural attributes and little else 自此与多位炙手可热的男明星合作,如与johnny depp合作的"太空异种"与tobey maguire合作的"心尘往事"与joaquin phoenix合作的"惊爆地铁" .值得一提的是莎莉在"怒海潜将"中与劳勃迪尼洛培养了好情谊,于是在"千钧一刻"中特别不挂名演出一位应召站的老鸨,并以浓妆出现
Otherwise , a bi - stable nonlinear system can be connected to the matched filter , and by adjusting the system parameters , the system will keep in single state for the detection of binary or multi - nary code , so that the detection performance can be remarkably improved in a wide range of sampling period 如果匹配滤波器的采样周期没有达到理想情况，则在它之前连一个双稳势的非线性系统，然后选择合适的参数使此系统始终处于单稳态，再对二进制或多进制码元信号进行检测，即使采样周期变化程度较大，检测性能也会得到显著的改善。
