In view of this point, Lu Ling's novels are of value, because strong intellectual complex is embedded in his novels describing either workers or peasants, in which the character's spiritual dynamics receives utmost concernViewing from the perspective of the intellectual quality-freedom, enlightenment and reflection, this dissertation seizes up the traits of intellectual character of Lu Ling's novels in 1940's, in an attempt to reproduce the sheen of his novels, and also to take a glimpse at the psychological journeys of the youth generation at that ageThose characters in Lu Ling's novels behave unbridledly all the way through their life journeyo They rebel against all the absurd things, declare war on tradition, family and newly rising authority, also anatomize themselves They resort nowhere Their life is closely linked to tramp It is right during the course of tramp and rebellion that they realize themselves, look for freedom and luminosity, and achieve real contact with people; they have enjoyed the unrestraint to their heart's content as well as experience torture from various forces in heartLu Ling's novels are affluent in connotation This dissertation only studies from the perspective of intellectual, the topics among which like: freedom, tradition, individual and collective are still worthwhile studying up to now.

从这一点出发，路翎的小说很有价值。他的小说不管是描写工人还是农民，都带有浓重的知识分子情结。他的关于知识分子的小说，更是极力关注人物的精神动态。本文从现代知识分子品质的角度——自由、启蒙与反思，打量路翎四十年代小说中的知识分子人物的特质，企图在这种论说中使路翎小说的光彩重现，也从中窥视那一代青年在那个时代的心路历程。他小说中的那些人物，在人生的道路上一路狂飙过去。他们反叛一切不合理的东西，对传统、家庭、新生的权威开战，也对自己身上旧的、暧昧的因子毫不留情。他们在哪里也停留不下，他们的人生和流浪紧密地联系在一起。在这个不断的流浪和叛离中，他们认识自己，追寻自由、光明，力求与人民的真正接触。也正是在这个背叛—寻找的过程中，他们享受了狂飙的酣畅淋漓，也体会到了内心各种力量撕裂的痛苦。路翎小说的内涵很丰富，本文只是抽取了知识分子这个角度进行研究。当中的一些命题：自由、传统、个人与集体在今天还是很有研究价值的。

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.
