Its working principle is introduced here: when a gas or powder starts a flame or explosion, the ultraviolet sensor will acquire the signal and sent it to the controller to produce the trigger voltage, and then the explosive suppressor will release a great number of gas promptly spraying dry powder extinguishing agents, which thereby form extinguishing agent smoke and effectively extinguish explosion flame. It is rapid and of strong antiinterference ability, high reliability and can be fixed easily. It is capable of effectively suppressing natural gas explosion in the simulative gas explosion test. It can be applied in CNG stations or other site where has explosive and combustible gas whereby to enhance the overall accident control ability.

当发生气体燃烧、爆炸时，紫外传感器接收火焰信号，传送至控制器，控制器产生触发电压，使抑爆器的产气剂释放出大量气体，驱动快速喷撒出干粉灭火剂，形成足够浓度的灭火剂粉雾体，有效扑灭爆炸火焰，具有动作速度快、抗干扰能力强、可靠性高、安装使用方便等优点，在天然气模拟爆炸试验中能有效抑制天然气爆炸，可用于CNG加气站或其他燃烧爆炸性气体场所，提高其整体防灾抗灾能力。

Direct shot can shoot most of times, movement shot and fill shot cannot shoot at that much. The most shooting happened at normal position. The gap between normal position and non-normal position is closer and closer. The percentage of non-direct confrontment shot far more than direct confrontment shot, and also this percentage is close to each other year by year.

直接射门的进球数量最多，运球突破射门和补射进球数量较少；绝大多数的进球是在正常状态下打入的，正常状态和非正常状态进球占全部进球的比例差距越来越小；非直接对抗射门进球数所占的比例远远大于直接对抗射门进球的比例，但直接对抗和非直接对抗的比例成逐年接近趋势。

It is the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.

镜头边界的检测是把视频自动地分割为一个个镜头，作为基本的索引单元，因此它是视频分析重要的第一步，直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题：渐变与镜头运动难以区别；渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测；自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上，指出使用单一的特征难以取得很好的检测效果，提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响，本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念，并根据帧间差的统计分布自适应地确定隶属度，以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频，并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测，研究了淡入／淡出、慢转换和扫换的模型。

The tracked shot-blast machine is with simple operation. Put the work-pieces into tracked rubber roller and close the shot-blast chamber door. Then setup shot-blast time and push the RUN button. Now, the shot-blast cleaning is beginning. The track circumrotates in the forward direction. The work-pieces can be equably and completely cleaned with equal emission of high-speed shots from the impeller of shot-blaster.

I'll describe a shot from the Exterior Brookfield sequence of an exterior of a row apartment on fire with an explosion blasting out the third story windows. The shot was composited on an Inferno by Bob Wiatr. We started with a live plate of the street scene. Our first task was to remove a foreground chainlink fence and camera crew. We recreated the fg matching the flashing ambulance lights. To create a snowy, misty look we used a number of logic ops of the bg with a mist plate which was basically the bg heavily blurred and multiplied back onto itself, graduating to create a sense of dimensionality. Glows were added around lights and flames using Sapphire plug-ins and light beams were added to streetlights. Four or five layers of 3d particle snow created in Maya were combined with practical elements varying in size and focus depending on distance from the camera.A miniature explosion element was incorporated into the comp, also with added glows, interactivity with the building, and rotoscoping of foreground objects. The entire comp was then time warped for editorial matching with the subsequent cut.

我可以描述一个Exterior Bookfield的几个镜头，那是一排的公寓着火，在三楼窗户引起爆炸，这个镜头是Bob Wiatr用Inferno合成的，我们用一个现场的街道镜头开始，我们的第一个任务是删除一个在前景中的链条状的篱笆和摄像人员，我们重新制作了前景以期与前景中的闪烁的救护车灯匹配，为了制作一个下雪的雾蒙蒙的效果，我们用了大量的logic ops，用了一个雾层，这个层基本上就是把背景尽量模糊然后再把它重新加到背景上面，渐变式的制作出一个层次感，自发光用Sapphire插件加在灯光和火焰的周围，而光线被加到路灯上，在maya中制作的四到五层的三维的粒子雪用来和不同大小的真实的素材混合在一起，焦距则依赖镜头的景深，同时在楼房爆炸的地方加入了一个缩小了的爆炸素材，以及爆炸的辉光效果，和重新放置的前景物体，整个的镜头接着匹配时间用来做最后的剪辑制作。

Regarding the general industrial dust aluminite powder, the firing delay time and the most tremendous pressure rise speed influence is very obvious to its maximum explosion pressure; Its maximum explosion pressure and the maximum pressure rise speed reduces along with the dust granularity increases: And increases the tendency to be obvious; Has a best dust loading, causes its maximum explosion pressure and the maximum pressure rise speed maximizing.

Using this theory, the flame structure of gas explosion in a horizontal pipe were studied, and the results show that: the gas explosion flame in a horizontal pipe is much thicker than that calculated from the former explosion theory, the intermediate products in the flame region are in separated state between the higher and lower level, and the cohesive force of the luminous body at lower level is bigger than that of the nonluminous body at higher level, there is a negative pressure region in the flame, and the flame splits easily in its propagating process.
