The design of image fountain signal, imaging technique and data processing are three key technologies to carry out CCD torsional oscillation measurement method. By analyzing the design principle, the paper devised an image source signal alternated with black and white strip and it has a good effect. Meanwhile, the system demand of imaging link was analyzed, such as light source, lens and camera etc. In addition, the principles of both the correlation algorithm and generalized correlation time delay estimation based on adaptive technology were studied, and a comparison between them was made as well.

If, on the other hand , we just continue to do our best in spite of wekness and hard work, we very often find that, with all our delaying and tacking about, we achieve more than others with their sailing and rowing-and-it gives us a true feeling of our worth if we keep pace with others or even overtake them.

反之，如果我们不顾自身弱点和世事艰难，尽力而为，坚持不懈，我们通常会发现，尽管有诸多的耽搁延宕、三心二意，我们的成就还是超过了那些奋力张帆摇桨的人，并且在我们能与他人并驾齐驱或超过他们时，我们就能获得对自身价值的真实感受。

I thank the gods for giving me such a brother, who was able by his moral character to rouse me to vigilance over myself, and who, at the same time, pleased me by his respect and affection; that my children have not been stupid nor deformed in body; that I did not make more proficiency in rhetoric, poetry, and the other studies, in which I should perhaps have been completely engaged, if I had seen that I was making progress in them; that I made haste to place those who brought me up in the station of honour, which they seemed to desire, without putting them off with hope of my doing it some time after, because they were then still young; that I knew Apollonius, Rusticus, Maximus; that I received clear and frequent impressions about living according to nature, and what kind of a life that is, so that, so far as depended on the gods, and their gifts, and help, and inspirations, nothing hindered me from forthwith living according to nature, though I still fall short of it through my own fault, and through not observing the admonitions of the gods, and, I may almost say, their direct instructions; that my body has held out so long in such a kind of life; that I never touched either Benedicta or Theodotus, and that, after having fallen into amatory passions, I was cured; and, though I was often out of humour with Rusticus, I never did anything of which I had occasion to repent; that, though it was my mother's fate to die young, she spent the last years of her life with me; that, whenever I wished to help any man in his need, or on any other occasion, I was never told that I had not the means of doing it; and that to myself the same necessity never happened, to receive anything from another; that I have such a wife, so obedient, and so affectionate, and so simple; that I had abundance of good masters for my children; and that remedies have been shown to me by dreams, both others, and against bloodspitting and giddiness...; and that, when I had an inclination to philosophy, I did not fall into the hands of any sophist, and that I did not waste my time on writers of histories, or in the resolution of syllogisms, or occupy myself about the investigation of appearances in the heavens; for all these things require the help of the gods and fortune.

我感谢神明给了我这样一个兄弟，他能以他的道德品格使我警醒，同时又以他的尊重和柔情使我愉悦；感谢神明使我的孩子既不愚笨又不残废，使我并不熟谙修辞、诗歌和别的学问，假如我看到自己在这些方面取得进展的话，本来有可能完全沉醉于其中的；我感谢神明使我迅速地给予了那些培养我的人以他们看来愿意有的荣誉，而没有延宕他们曾对我寄予的愿我以后这样做的期望（因为他们那时还是年轻的）；我感谢神明使我认识了阿珀洛尼厄斯、拉斯蒂克斯、马克西默斯，这使我对按照自然生活，对那种依赖神灵及他们的恩赐、帮助和灵感而过的生活得到了清晰而巩固的印象，没有什么东西阻止我立即按照自然生活，然而我还是因为自己的过错，因为没有注意到神灵的劝告（我几乎还可以说是他们的直接指示）而没有达到它；我的身体置于这样一种生活之外如此之久，我从未达到本尼迪克特或西奥多图斯的高度，但在陷入情欲之后，我还是被治愈了；虽然我常常达不到拉斯蒂克斯的那种气质，但还是没有做过使我悔恨的事情；虽然我母亲不能尽其天年而终，但她最后的年月是与我在一起的；在我希望帮助任何需要帮助的人的时候，或在任何别的场合，我都不感到我缺乏这样做的手段；而对我自己来说却不会有同样的需要：即需要从别人那里得到的东西；我有一个十分温顺、深情和朴实的妻子；我有许多优秀的教师来教育我的孩子；通过梦和其他办法，我发现各种药物来治疗咯血和头昏……当我有一种对哲学的爱好时，我没有落入任何诡辩家之手，没有在历史作品上，或者在三段论法的解决上浪费时间，也没有专注于探究天国的现象；而上面所有这些事情都要求有神灵和命运的帮助。

The computational complexity has been reduced about 5 times over against the original one. Moreover, the interpolation and quantization processing of CW is more reasonable; 2. A secondary power normalization algorithm is proposed in this dissertation. This normalization algorithm ensures that the energy sum of SEW and REW is 1. So, the energy ratio of SEW and REW can be achieved only by using SEW energy. This ratio is applied in REW quantization and CW composition; 3. For more efficient quantization for Slowly Evolving Waveform magnitude, Rapidly Evolving Waveform magnitude and power parameters, firstly, by applying the Equivalent Rectangular Bandwidth theory, classifiable multi-codebooks method, analysis-by-synthesis approach and so on, a predictive AbS multi-codebooks SEW magnitude quantization scheme is proposed. In the scheme, pitch information is exploited to determine which codebook is searched; secondly, for REW magnitude quantization, this dissertation proposed a DCT-matrix multi-codebooks quantization scheme. The classification in muti-codebooks is based on pitch and quantized SEW power. The multi-codebooks structure may offer more the information in quantization and solve the problem of the bit requirement limits in quantization by consuming some extra storage space; Furthermore, for the switch quantization of CW gain, a new classified parameter is proposed.

本文的主要贡献体现为如下几方面：一、为了减少WI模型的计算复杂度，提出了基于快速傅立叶变换、三次B样条插值和周期延拓技术的特征波形(Characteristic Waveform，CW)表示和对齐的快速算法，与原方法相比，计算量下降到原方法的1/5，同时也使得CW在插值和量化时更合理；二、为了严格保证SEW与REW的能量和为1，提出了一种特征波形的二次功率归一化算法，仅需要SEW能量就可以算出二者的能量比，并可应用到后续的REW的分类量化和CW合成中；三、为了对慢渐变波形(Slowly Evolving Waveform，SEW)幅度、快渐变波形(Rapidly Evolving Waveform，REW)幅度和特征波形功率进行有效量化，本文首先采用临界频带理论、分析合成技术、感觉加权技术以及预测式矢量量化技术，提出了一种基于基音周期分类的SEW分析合成预测式多码书量化方法；其次，本文根据基音和量化后SEW的功率信息对REW幅度进行分类，提出了一种基于离散余弦变换的REW矩阵多码书量化方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
