Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.

由于信元抖动的复杂性，非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能，以及在目的节点的源定时恢复问题作了较为全面的研究。首先，文中描述了CBR业务流的信元抖动，并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后，采用了精确的数学模型和分析方法，有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法，在性能分析中，我们成功地完成了CBR业务流信元抖动的功率谱分析，使得不但可以从频域定性地认识信元抖动的能量分布特性，而且还可以定量地求出信元抖动的均方根值(rms：root-mean-square)，以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中，我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流，并基于这一模型进行了CBR业务流中间节点的初步排队分析。
