Cubic non-uniform trigonometric polynomial curves with multiple shape parameters are presented in this paper. They are C^2-continuous for a non-multiple knot vector and C^3-continuous for a uniform knot vector respectively. The ellipses can also be represented by them.

In Basilidianism it is the Third Filiation that is captive in matter, and is gradually being saved, now that the knowledge of its existence has been brought to the first Archon and then to the Second Archon, to each by his respective Son; and the news has been spread through the Hebdomad by Jesus the son of Mary, who died to redeem the Third Filiation.

在Basilidianism这是第三次亲子关系是圈养的问题，并正在逐步被保存，现在的知识，它的存在，已提请第一执政官，然后给第二执政官，每个由他各自的儿子；和新闻已传播到Hebdomad由耶稣的儿子，玛丽，谁丧生赎回第三次亲子关系。

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。

For more upgrade aluminium oxide yield, optimize indices, energy conservation and save cost, it is necessity to desilicify steps reconstruction.In order to overcome the shortcoming of the desilication used in Shangdong Alumina Corpotation,three technology such as indirect heating, continious desilication,deep desilication by separation of the sodium-silicon residue.

Back in my kidhood music was kind of luxury in my isolated mountain village and one of my neighbors, who had got some relative in the town who had passed a used recorder onto him, wired a thundering loudspeaker to this recorder and proudly and loudly, played some out-of-date tapes regularly, 3 times a day, and 3 hours each time.

回首我的童年时代，在我们那个与世隔绝的小山村里，音乐似乎是一种奢侈品。我的一个邻居从城里的亲戚那里得到了一个用过的录音机。他用电线把它与一个音量很大的扩音喇叭连在一起，自豪并且大声地定期播放一些过时的带子，一天三次，一次三小时。
