In addition, we proposed a new approach to implement a descrambler. The security problem of speech communication has always been a demanding problem in military and business areas. A common approach to realizing end-to-end security is the use of a scrambler. Most of the scramblers are based on the permutation of speech signals in the time domain and/or frequency domain. On the other hand, descramblers are used to eavesdrop information from scrambled speech signals. We treated the descrambling problem as a puzzle solving problem. Some speech signals were used to demonstrate the performance of the proposed methods.

接著我们将此演算法应用於语音通讯保密的语音解搅拌器上，语音通讯保密已经被广泛应用在军事与商业领域，一般的作法是将语音搅拌器使用在端点对端点的保密上，而大部分的语音搅拌器都是以时域与频域为基础来进行排列搅拌，另一方面语音解搅拌器也必须防止窃听者盗取搅拌后的语音讯号，在此实验上，我们将语音解搅拌的问题视为解拼图的问题，并且利用我们所提出的解拼图方法来实作其应用，最后我们采用一些范例来展示其结果。

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch.
