在运动

The equipment has crept forward in its technology since Robin and his merry men had the run of Sherwood Forest, but the sport of archery remains essentially unchanged.

与罗宾汉和他的手下在舍伍德森林中占山为王的时代相比，射箭运动的器材装备在技术上已经逐渐进步了不少，但是这项运动在本质上并没有改变。

Hydraulic planer the advantages of a smooth drive, theintroduction of hydraulic drive, ram a uniform velocity,and canachieve variable speed; load capacity than the general mechanicaltransmission large Shaper;ram can be in any position toimmediately stop or start;Stage movement to apply the hydraulicdrive,feed rate can be in a certain range without adjustments;Machine done by hydraulic valve protection, are not too easy todamage the machine parts;Part of the oil is not easy to workwear, so long machine life;manipulating simple andconvenient.

液压刨床的优点是传动平稳，由于采用液压传动，滑枕的运动速度均匀，且可实现无级调速；负荷能力比一般机械传动的牛头刨床大；滑枕可以在任何位置上立刻停止或起动；工作台的进给运动也采用液压传动，进给量可以在一定范围内无级调整；机床由液压安全阀做保护，过载时不容易损坏机床的零部件；零件在油里工作不易磨损，因而机床寿命长；操纵简单，使用方便。

Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seals to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean's surface and last for over 70 minutes.

在实验室对于海豹的研究已经能够描述出与无氧情况相适应的海豹身体的运动机理，这样的运动能使海豹在最长的一冲中，深入到海下500米处，且能够在水下呆上70分钟。

The difference is that the relay-like plunger is composed by two separated plungers in different size and reciprocate in corresponding tube in the process of lifting, and the two separated plungers automatically dock with each other when the relay-like plunger is in the process of up stroke and separate in the process of down stroke and constitute the process of the relay plunger lifting.

所不同的是，组合油管接力式柱塞举升系统的卡定器下到下部小油管中，柱塞由大、小两个分体式柱塞组成：小柱塞在下部小油管内运动并实现在小油管中的举升，大柱塞在上部大油管内运动，上行程时小柱塞可与大柱塞自动对接并完成举升的接力，下行程时小柱塞可与大柱塞自动脱离。

According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.

论文根据多传感信息融合实验系统中的分布式飞行仿真系统、光学信号处理器和图像多目标跟踪系统三个子系统的功能要求，具体完成了以下三方面的工作：首先利用建模软件Creator创建分布式飞行仿真系统中的大面积地形、场景中的地面雷达模型和峡谷地形，并在仿真过程中实时驱动雷达模型的扫描，同时为后续雷达仿真模块提供实时地形编码；其次利用仿真软件Vega，在分布式仿真系统中为光学信号处理器设计实现了光学通道，模拟飞行器的光学摄像机的功能，并且对由此通道获得的目标二维光学信息进行转化处理，作为光学信息源发送给后续的多传感信息融合器；最后针对图像多目标跟踪系统，在研究图像分割运动估计算法的基础上，通过分析影响块匹配算法速度和精度的因素，改进了块匹配运动估计算法，结合差分法可应用到目标跟踪系统中。

Notice near the center that in traveling from 66 to 7 you strike the angle of 180* or 90*, but when the stock gets out to 162,it can travel up to 169 before striking another strong angle . That is why fast moves occur up and down as stocks get higher and as they move from a center of time.

注意在中心附近从66滑到7，你将撞击180度或90度，但是当股票跳过162去，在撞上另外一个强的角度之前他们可以达到169 ，这就是股票从时间的中心开始运动并为什么在比较高的价格上发生快速上下运动的原因。
