理论分析与实验结果证明了该方案的有效性。

In the end-to-end path capacity measurement based on packet pair algorithm, there are some inference factors with effects on the measurement result, such as cross traffic, packet pathology and clock precision. The influence of these inference factors was discussed based on theoretical analysis and experiment data.

The method to configure RED parameters based on network properties is also presented. Simulations show that the modified Random Early Detection algorithm really performs better than the original Random Early Detection algorithm and can work for a much wider range of traffic. Finally, whether the assured service mechanisms i. e. an edge router tags every arriving packet of a TCP flow based service profile and core router drops packets differently at congestion using active queue management scheme is possible to provide a throughput consistent with target rate, is investigated under different network scenarios. Different factors including target rate tagged algorithm, RIO algorithm and TCP congestion control mechanism how to affect the throughput of an assured service TCP flow are examined. Based on a fluid model. we then derive a model of an assured service TCP flow, which is the function of round trip delay, packet loss rate and token bucket parameters. Based on this model, we observe that in some cases it is possible to regulate the token bucket parameters to gain a consistent throughput with the target rate, while in other cases there exist ranges of values of the achieved rate for which the token parameters have no influence. With the latter, some modified TCP congestion control mechanisms to assure TCP throughput are proposed.

最后，在区别服务网络结构内，研究了当前提出的一种边缘路由器根据服务合同标记、分类数据包，结合内部路由器采用主动队列缓冲管理机制区别处理数据包的确信服务机制是否可在不同网络情况下使TCP连接获得同目标速率相一致的、公平的吞吐量问题；指出影响TCP连接获得同目标速率相一致吞吐量的主要因素是目标速率大小、标记算法参数和TCP连接的拥塞控制算法；对此，基于流模型假设，首次推导出一个以端到端时延、数据包丢失率、漏桶参数为变量的确信服务TCP连接吞吐量模型；利用这个模型进行分析，得到主要结论是在一些情况下可通过设置合适的漏桶参数得到同目标速率更一致的吞吐量，而在另一些网络情况下不管如何设置漏桶参数都不能使TCP连接获得同目标速率一致的吞叶量；对于后一些情况，还初步讨论了改进TCP拥塞控制算法来改善TCP连接性能的方法。

Thereinto, Yunnan Tobacco Machinery Plant manufacture main machine (Model YB22A soft packet packing), Kunming Tobacco Machinery Group NO.3 Machinery Co., Ltd. manufacture auxiliary machine (Model YB52A Cellophane Wrapper For Packet/Model YB62A Carton Packing Machine/Model Cellophane Wrapper For Carton), each machine can finish each packing process individually.

Wavelet packet decomposition can decompose high-frequency part of signal. In order to obtain the energy rate index of each node this paper advances apply wavelet packet decomposition method to node response of pipe. And then use statistics method to analysis the energy rate index indicator of various nodes in pipe. Results show this method not only can detect the locations of damage in pipe, but also can get a preliminary study for quantify the damage degree damage of pipe.

本文提出将小波包分解方法应用于管道的节点响应，得出各个节点的能量率指标，并利用数理统计方法对管道上各个节点的能量率进行统计分析，结果表示该法不仅能确定管道的损伤位置，而且还能对管道损伤程度的定量分析作一个初步的研究。

Dantès obeyed, and commenced what he called his history, but which consisted only of the account of a voyage to India, and two or three voyages to the Levant until he arrived at the recital of his last cruise, with the death of Captain Leclere, and the receipt of a packet to be delivered by himself to the grand marshal; his interview with that personage, and his receiving, in place of the packet brought, a letter addressed to a Monsieur Noirtier--his arrival at Marseilles, and interview with his father--his affection for Mercédès, and their nuptual feast--his arrest and subsequent examination, his temporary detention at the Palais de Justice, and his final imprisonment in the Chateau d'If.

于是唐太斯开始讲他自己的身世了，实际上只包含了一次到印度和几次到勒旺的航行，接着就讲到了他最后这次航行；讲到了莱克勒船长是如何死的；如何从他那儿接过一包东西并交给了大元帅；又如何谒见了那位大人物，交了那包东西，并转交了一封致诺瓦蒂埃先生的信；然后又如何到达了马赛，见到了父亲；他还讲了自己是如何与美塞苔丝相爱，如何举行他们的婚宴；如何被捕，受审和暂时押在法院的监牢里；最后，又如何被关到伊夫堡来。
