The fuzzy flow-awareness with the load state information can identify different services congruously in path. And the dynamic priority fairness scheduling algorithm based on fuzzy flow-awareness will adjust the priority of forwarding dynamically between streaming flows and elastic flows by changing the threshold of priority queue. The algorithm emphasizes the fairness of scheduling under the light load and the priority of real-time applications under the heavy load for their delay requirements.

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。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

The major works are as follows: 1 The 3-D numerical model of U-sharp flow passages is set up. The single-phase fluid flow and heat transfer are simulated for the U-sharp smooth and rib-roughened flow passages with FLUENT software. Their performance curves, temperature field and velocity vector are obtained and the local heat transfer and flow pressure-drop distribution along flow passage are analyzed. It is revealed that the ribbed flow passages can enhance heat-transfer and make the temperature more uniform, but it increases the pressure-drop to more extent. 2 The influences of diaphragm depth, channel width and board spacing on the performance are investigated.

My son 5 years old, when two-year-old on the occasional nosebleeds, small, 4-year-old when more than three months on the stream once every 10 days for half a year and a half months ago on the flow time, and also more than the original, to the hospital, said blood tests are normal, the point of medicine at the children do not love the beginning of .8 month almost 32 days on stream, but also very large, went to the hospital check, blood test or normal, open points syrup, and eat Chinese medicine granules, not a week, drug use is also a day on the 15 o'clock a sudden nose bleeding out, exhausted all the methods normally used only finally stopped, six o'clock in the morning and a stream, though not at night, and also have more than the original (the child was afraid I worry that the deal did not tell my own, I was based on the many large blood on the ground and pumping his college paper used judgments), or normal blood, the cream of the point that no matter, I was pleased, but the children come back again every day flow, and sometimes more than once or twice a day, which is a headache for two days and asked him if he do not understand how that specific pain law, is not the teacher the past two days that he said he did not love school is really a headache or a headache, I was to determine if a teacher said he does not love the child's school is a small trick.

5岁男宝宝经常流鼻血，最近两天又说头痛怎么办我的宝宝5岁了，两岁多的时候开始就偶尔流鼻血，量少，4岁多的时候开始三两个月就流一次，半年前开始隔十天半月就流一次，并且也比原来多，到医院验血说都正常，开点上的药水宝宝不爱点。8月分开始几乎三两天就流，还非常多，又去医院查，验血还是正常，开了点药水，和吃的中药颗粒，没到一周，还正用药，一天夜里3点就突然鼻子向外大量流血，用尽了平时用过的所有方法才好不容易止住了，早上六点又流了一次，虽没有夜里多，也是比原来都多(宝宝怕我着急，这次没告诉我自己处理的，我是根据地上的许多大血滴和他用过的纸抽团判断的)，血还是正常，开了点药膏，说没什么事，我挺高兴的，可是宝宝回来又是每天都流了，有时一天还不止一两次，这两天说是头痛，问他又说不明白具体怎么疼法，是不是老师这两天说他他不爱上课就说头痛还是真的头痛，我正在判断中，如果是老师说的他就不爱上课当然是宝宝的小把戏。
