The result show that the N elements curbed the transition from anatase phase to rutile phase , Doped-N was in the structure of the TiO2 as the form of Ti-O-N and formed a new bond energy level;N-doped changed the paramagnetic of the characteristics. The paramagnetic resonance spectrum of TiO2 showed anisotropic and showed hyperfine splitting, The Lande factor of Ti3 + combined with the N is 1.956. UV-Vis absorption spectra showed that the photocatalytic ability of photocatalyst TiO2-xNx to expand to the visible region, the sample (3.84wt %) has the highest photo catalytic activity, the adsorption edge extend to 520nm and degradation is 55.54% under the visible light for 1.5h.

研究结果显示，N元素抑制了锐钛矿相向金红石相的转变，阻止了晶粒的长大，掺杂的N元素以O-Ti-N的形式存在于光催化剂结构中，形成了新的能级结构；N掺杂改变了催化剂的顺磁特征，使TiO2的顺磁共振谱线呈现各向异性，发生了超精细分裂，其中g2=1.956，是与N结合的Ti3+的朗德因子；紫外可见光吸收谱表明，催化剂TiO2-xNx的光响应能力拓展到可见光区，光吸收带发生红移；光催化测试结果显示，掺杂量为3.84的TiO2-xNx在可见光区的响应能力最高，吸收波长延伸至520nm，其光催化活性最大，1.5h降解率达到55.54%。

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。
