The first step is to eliminate all kinds of noises generated in the process of collecting traffic video by means of median filter; Then we finish image sharpening with Laplace operator to clarify edges of the video images; finally, image contrast is enhanced with the help of the second-developing packet SDK-2000, which is provided by our video-collecting card. This way, much more satisfactory images are obtained, and preparation is already made for the following work, thats image analyse.Thirdly, according to the characteristics of our system, mobile objects are distinguished by means of image difference. Then some features such as regional area, length and width of traffic objects are selected and extracted. After processing of scale filter, we successfully recognize those moving vehicles appearing in the monitoring regions.Fourthly, some corresponding algorithms are brought forward to automatically identify those familiar traffic peccancies of many sorts, such as red light violation, yellow-line covering, parking in prohibited spots, over-speed running and converse running. Then we find means to snap pictures and to intercept videos of the spot, and collect a lot of relevant information such as the time, the block, the running direction and the weather conditions and so on. According to this information, our traffic management departments could make correct decisions on punishing those drivers who have broken the traffic rules.Considering the complexity of traffic environments on particular blocks, in order to monitor other traffic peccancies effectively, we also have designed the scheme to carry out traffic monitoring by manual.

首先运用中值滤波法对视频图像进行去噪处理，然后采用二阶差分法进行图像锐化，再通过视频捕获卡携带的二次软件开发包SDK-2000进行对比度增强，从而得到比较理想的图像，为后续的图像分析工作做准备；第三，根据系统特点，通过背景图像差分法，分割出监测区中的运动目标，然后对交通目标的区域面积、长度和宽度等进行特征提取，再经过尺度滤波处理，从而自动识别出机动车辆目标：第四，分别设计相应的算法，实现对闯红灯、压黄线、违章停车、违章超速及违章逆行等常见的交通车辆违章行为的自动识别，并自动抓拍违章现场，截取违章视频，采集其它相关违章信息，为交通执法部门进行交通违章处罚提供有力依据：考虑到特殊路段特殊环境下的交通复杂性，为了有效监控其它类型的交通违章行为，本文还设计并实现了对交通违章的手动监控模式。

Further, a vapor discharge opening and a vapor discharge valve mechanism are provided in that part of the pump channel which is between the air discharge opening and an inlet section of the pump channel. The vapor discharge valve mechanism is closed in the start of the pump, preventing negative pressure at a fuel suction opening from being reduced, and the mechanism is opened in the start of fuel pressurization, discharging fuel containing vapor to the outside of the pump channel.

另外，在上述空气排出口和泵流路的入口部之间的泵流路上设置蒸汽排出口，此外设置蒸汽排出阀机构，其在燃料泵启动时闭阀而防止燃料吸入口的负压降低，如果燃料加压开始则开阀，从而将含有蒸汽的燃料向泵流路的外部排出。

When they were close up with one another, the son of Atreus missed his aim, and Iphidamas hit him on the girdle below the cuirass and then flung himself upon him, trusting to his strength of arm; the girdle, however, was not pierced, nor nearly so, for the point of the spear struck against the silver and was turned aside as though it had been lead: King Agamemnon caught it from his hand, and drew it towards him with the fury of a lion; he then drew his sword, and killed Iphidamas by striking him on the neck.

现在，他将在此迎战阿伽门农，阿特柔斯的儿男。他俩相对而行，咄咄逼近，阿特柔斯之子出手投枪，未中，枪尖擦过他的身边，但伊菲达马斯却出枪中的，打在胸甲下，腰带的层面，压上全身的重量，自信于强有力的臂膀。尽管如此，他却不能穿透闪亮的腰带，枪头顶到白银，马上卷了刃尖，像松软的铅块。阿伽门农，统治着辽阔疆域的王者，抓住枪矛，抵捅回去，狂烈得像一头狮子，把枪杆攥出他的手心，然后举剑砍进脖子，松软了他的肢腿。
