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。

Two improvements measurements pointed to the errors to calculating b values have been proposed:(1) to adopt the uniform absolute magnitude scale, seismic moment magnitude MW,(2) to discard the magnitude points for which the earthquakes absent and lose, and then to compute the b value using least square method to fit the data.

针对过去计算b值的误差，提出了两条改进措施：（1）采用统一的绝对震级标度-矩震级标度MW；（2）舍弃缺失地震次数的点，然后用最小二乘拟合求得b值，使b值计算较准确。

与magnitude相关的网络解释 [注：此内容来源于网络，仅供参考]

magnitude：震级

虽然都是描述地震,强度和烈度两个完全不同的概念.强度用震级(MAGNITUDE)衡量,指的是地震时释放的能量.烈度(INTENSITY)则是指地震造成的危害.很明显,一个地震的强度是固定的,而同一强度的地震,

magnitude：大小

亚里士多德在>中不是说,悲剧应该有相当的"大小"(magnitude)吗?这正是鹏程兄上面所说的,一首五言绝句,怎能"具有>的磅礴与翻腾"?龚教授不是个形式主义者,然而,我和他有同感:管你是文雄诗杰,也难以不为形式折腰!

magnitude：数量

但是这些数量(magnitude)不能等同于的经济学概念的利润和亏损,千万不能混淆了它们. 如果一个税法把某个数量称为利润,那么实际上它就决定了应收税款的高度. 它把这个数量称为利润是因为它想在公众的心目中为税收政策而正名.

magnitude：量

比如在固定电话或者传统电话为主的时期,AT&T作为一个老牌的国家级的电信运营商,它的份量(magnitude)是够大的,但是在互联网、和无线通讯广泛应用的时代它在技术推动、创新的爆发力--"I" 方面就显得不足,更不用去谈像它的竞争对手那样"无处不在".

earthquake magnitude：震级

震级(earthquake magnitude)是表示地震本身大小的量度指标,是以地震仪测定的...震级(earthquake magnitude)是表示地震本身大小的量度指标,是以地震仪测定的每次地震活动释放的能量多少来确定的.
