大面积

For a variety of quadrochromatic téléphoner, transmission, equipment many out of, this requires the operator has a definite students'aesthetics, should be such that the overall color picture, and the color is closer to its true effect, given a picture of the black and white, a very small area of the hihglights Department may, in part, in the vast network of public interest on a large area, mediation should be retained.

由于各种原稿受时间、传输、设备许多出素的影响，这就要求操作者具有一定的审美观，应使彩色图片整体不失真，颜色接近其真实效果，设定好图片的黑白场，小面积的极高光处可以绝网，但大面积部分切忌绝网，暗调处应保留层次。

An additional consideration is that such spaces are often located at the perimeters of buildings; frequently have large areas of glazing; and also experience significant air exchange with the outside environment.

另一个考虑因素是，这种空间往往设在周边的建筑物；经常有大面积的玻璃幕墙；和经验还显着空气的交流与外部环境。

Windows are positioned to provide visual breaks in the public spaces of the museum, and to draw attention to the surrounding context at different scales, from closeup views of the historic facades and pediments of the adjacent Lillian Massey and Margaret Addison buildings to framed sequences of the ROM's heritage building and new Crystal expansion across the street.

博物馆的公共空间设计了大面积的窗户，在这里，人们的视觉将得到放松，并被周围不同尺度的建筑背景所吸引。视线从博物馆邻近的历史上著名的Lillian Massey and Margaret Addison建筑群那美丽的正立面及山墙开始，延伸到ROM的传统建筑、新建的水晶建筑，再扩展至街道对面。

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。

In October 2004, the power outages in large area of United States and Canada have caused tremendous loss in economy.

2003年8月发生在美国和加拿大的大面积停电事故造成了巨大的经济损失。

Focusing on all these functional traits, 13 functional groups were identified by TWINSPAN (two-way indicator species analysis), and their change with different environmental factors, disturbance types and recovery time was ordinated by DCCA(detrended canonical correspondence analysis).

本文以海南岛霸王岭林区作为海南岛热带林的典型区域，以反映不同环境因子、干扰类型和恢复时间的热带山地雨林为研究对象，在大面积(15hm~2)样地调查的基础上，依据物种的7个功能特性(喜光性、潜在高度、板根大小、木材密度、种子生物量、传播方式和落叶／常绿性)，分别把物种划分为不同类别的功能群，应用NMS分析了各功能群随不同干扰类型和恢复时间热带山地雨林群落的变化规律。

Results: Among 140 patients with cerebral infarction, 32 patients suffered vascular dementia (22.9%, 32/140). Freguent onsets (≥2), large areas and multiple infarction are the risk facto for the vascular dementia following cerebral infarction.

结果：其中32例患者发生血管性痴呆，脑梗死后血管性痴呆的患病率为22.9%(32/140)，发病次数≥2次、大面积及多发性梗死是脑梗死后血管性痴呆发生的重要危险因素。
