研究表明：交通流诱导负效应的产生主要是由于信息条件下的道路出行者路线选择行为的不确定性引起的，而且交通流诱导与控制同时进行是消除交通流诱导负效应产生的关键。

The flow pattern signal is approximated by convolution of standard singular function and Gaussian function on every scale, and singular exponential of signal local singular points can be worked out with least square method.

本文基于流型信号奇异性分析的结果得到了分层波状流和段塞流模糊判别的隶属度函数。

There are three kinds of fluid muds according to the dynamic conditions. The first one was formed at slack water during flood and ebb tides with a large scale but small thickness. The second was formed at area of grows saltwater wedge with small scale and thick depth.

在成因类型上分为憩流浮泥、盐水楔浮泥和风暴潮浮泥，第1种在涨或落潮转流期低流时形成，规模大，厚度薄；第2种在盐水楔发育时形成，规模较小，厚度较大；第3种在大风后形成，规模大，范围广；若三者相遇，则浮泥厚度和范围最大。

To all project practicality, the introduction is given to the operational characteristics, the methods for calculation and the researching actuality of the tail tunnels with sloping ceiling underground hydropower stations the Three Gorges. This paper has discussed in detail the characteristic method being the same with the compressive flow and the Priessmann solution being the same with the free-surface-pressure flow. And how to deal with boundary conditions has been expatiated. Also hydraulic transient process of tremendous load fluctuation in the tail tunnels with sloping ceiling has been numerical simulated and the Fortran program for numerical simulation has been given. The paper gain the maximal press for tail end of the shell, the maximal rising rate of rotational speed of generating set, the maximal vacuum degree for inlet of the tail tunnels and so on under 11 kinds conditions of tremendous load fluctuation. These conditions include the design conditions, the check conditions and the superposition conditions. Finally, the computing results have been analyzed and summarized. The end chapter is the general comment of the whole-length content and the describing of the intending view of researching.

The multimedia smart terminal (36) includes a smart terminal sub-stream switch (64) configured to switch among the plurality of secondary multimedia sub-streams in order to select a substantially optimum secondary multimedia sub-stream.

多媒体智能终端(36)包括智能终端子流(64)，它被配置为在多个次级多媒体子流之间切换以选择基本优化的次级多媒体子流。

There are three kinds of experiment have been finished: CMT no drain, CMT drain with sparger, CMT drain without sparger .

实验内容包括CMT无遮流板不排水、CMT无遮流板排水和CMT加遮流板排水三个方面。

After analyzing the radial and axial temperature distribution of CMT, the primary result has been concluded: With the same initial pressure of the CMT drainage with sparger, the higher the average temperature of CMT fluid is, the shorter the disturbing time, and the large the temperature difference of the top and bottom layer fluid.

对实验测得的CMT径向和轴向温度分布进行了分析，发现在PRZ初始压力相同时CMT无遮流板排水，其扰动时间随CMT液体平均温度的升高而减少，上下层液面温差随之变大；加遮流板后对凝结和温度平衡时间起主要影响的因素有两个，即遮流板以上液体的温度与PRZ的初始压力大小。

After analyzing the CMT drainage mass under different initial condition, the primary result has been concluded: The CMT drainage velocity is related to the change of CMT pressure, the drainage mass of CMT without sparger increase monotonously along with time, and has a obvious inflexion.

遮流板对减小凝结起着积极的作用，在蒸汽完全凝结和部分蒸汽快速凝结阶段下CMT加遮流板其凝结换热系数较无遮流板时减小了3—5倍。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
