Then the flow in the curved pipe and reducing pipe was simulated through using CFD software, know that fluid passing curved pipe, reducing pipe can form secondary flow, vortex shedding, circumfluence, occur separation of boundary layer and periodic circulation flow, make the fluid pulsant, then cause the pipe vibrancy.

然后再应用通用CFD软件对具有弯曲和变径的热风炉管内流场进行模拟，得到当流体流过弯管、文氏管后形成了二次流、环流，并发生边界层分离和周期性旋涡脱落，它们会使后面的管流处于脉动状态，脉动状态的流体在管内流动时，会引起管道系统产生振动。

In comparing the floral morphogenesis with that of other genera with T-type chromosomes in the family, we considered that Coptis contains some primitive characters. The results are consistent with molecular systematic studies showing Coptis as one of the basal groups of Ranunculaceae.

通过与其它具T-型染色体类群在花形态发生上的比较，认为黄连属表现出了某些原始的性状，这一结果与分子系统学研究认为黄连属为毛茛科的基部类群的结论一致。

The longer the virus circulates the way it does in poultry production systems and in ducks, the higher is the probability of exposure of humans and if we are indeed unlucky and have human influenza at the same time, there is increased likelihood of reassortment and therefore of the generation of pandemic.

病毒在禽类生产系统和鸭子中传播的时间越长，人类接触到病毒的可能性越大。如果我们不幸同时患有流感，这两类病毒之间再组合的可能就会增加，因此发生流行病的可能性也会增加。

They are trying to repair a breakdown in the refrigerating system.

他们正在全力失修发生故障的冷却系统。

Protection of vertical and cross direction is proposed. The principle and installation of differential protection and directional over-current protection which applied to ringlike type power network is presented.

船舶电力系统的各种型式的电网均要设置相应的保护装置，以便在电网发生各种故障时保护装置能选择性地动作将故障切除并

The occurrence of social public events will affect the normal order of urban road transportation system. Analyzing the theory and course of the impact of the events to road traffic based on the scientifical classification of events is crucial to research how to improve the level of traffic management.

社会公共事件的发生直接影响到城市道路交通系统的正常运行，在对社会公共事件科学分类的基础上，分析事件对城市道路交通的影响机理及过程，对于提高城市交通管理水平具有重要的意义。

The invention discloses an elastic sectionalization ring address binding method in the network transmission technological domain, which is characterized by the following: realizing the binding of RRP ring node MAC address and IP address through ATD frame in the extended RPR protocol; without adding extra system resource consumption; converging rapidly for topology after the RPR looped network occurs switching; providing address binding information for over three layered report to transfer and utilize.

本发明涉及传输网络技术，公开了一种弹性分组环地址绑定方法，使得在不增加额外系统资源消耗的情况下实现RRP环节点MAC地址和IP地址的绑定，并且在RPR环网发生倒换后，拓扑可快速收敛。本发明中，通过扩展RPR协议中的ATD帧，在广播ATD帧的同时携带MAC地址和IP地址绑定的信息，实现所有RPR环节点的MAC地址和IP地址的绑定，该地址绑定信息可供三层以上报文转发使用。

Some conclusions are drawn which by analyzing the experimental data.There are seriate pores with continuous diameters in the coal, some of which are fracture-type.The pore volume of the coal is mainly...

分析表明，大同煤具有连续的完整的孔系统，且部分孔为狭缝毛细孔；孔体积主要由大孔和中孔构成，比表面积主要由小孔和中孔构成；随着颗粒粒度的减小，煤粉的孔隙结构发生变化，致使比表面积和孔容积均增大，平均孔直径减小。

Under this background,this paper refers to the concept of SISE and analyzes the world relevant research and practice state. Furthermore, this paper initiatively uses the theory of early-warning management in the field of SISE and builds up the function system, management organization, management object, operation procedure and the proces...

在此背景下，文章在提出社会重大事件的概念之后，分析了目前的国内外相关研究和实践应用现状，主张应将预警管理理论应用于系统防范重大社会突发事件领域，构建了重大社会突发事件预警管理模式的功能体系、管理主体与对象以及活动内容和运转模式，为降低社会重大突发事件的发生和不良后果提供了一个新的解决思路。

Be thinking about: the connections between this event and other events or sociotechnical systems (connections that might illuminate our understanding of what has happened).

同时思考：这一事件与其他事件的联系，或者这一事件与社会技术系统的联系（这些相互关联可能表明我们对已发生事情的看法
