空中交通管制

According to this model, the capacity evaluation system of Xi'an Xian Yang International Airport was developed by utilizing the programming method of Object Orientation; comparing the results of former evaluation system and that of this one, the correctness of the proposed model was verified; the airport's running status and flight delays were researched through statistics of the system, providing airport ground controllers with reasonable advices.

根据这一模型，以西安咸阳国际机场为背景，采用面向对象的程序设计方法，开发机场地面容量评估系统；将系统评估所得结果与原有理论容量评估结果进行比较，验证了评估模型的准确性和优越性；对评估结果进行统计计算，分析机场不同空中交通流量下的运行情况及延误分布情况，为机场地面管制提供参考性意见。

It also brought leaps in air-traffic control and cargo handling. It even featured a primitive but effective electronic data interchange, jury-rigged from telex machines.

空中运输大量煤炭，还给航空交通管制和货运管理带来了飞跃，甚至还用电报机临时搭建起了简单粗糙，但行之有效的电子数据交换系统。

The airlift was not just the only time in history when large quantities of coal have been delivered by air. It also brought leaps in air-traffic control and cargo handling . It even featured a primitive but effective electronic data interchange, jury-rigged from telex machines.

这次空运，不仅仅在历史上首次空中运输大量煤炭，还给航空交通管制和货运管理带来了飞跃，甚至还用电报机临时搭建起了简单粗糙，但行之有效的电子数据交换系统。

The distributed fusion algorithm was applied to process the fusion tracks from local ATC center,and solve the problem of the poor quality of the track on the fusion edge.

为实现全国范围内的空中交通动态监视，必须将分布于全国各地的管制中心的雷达融合数据经通信线路传送到全国空情融合中心，常用的办法是进行动态雷达数据拼接，在拼接边界存在航迹平滑度差，航迹易跳变等问题。

Air traffic was so dense that afternoon that air-traffic control could hardly cope.

那天下午的空中交通太密集了，所以空中或航空交通管制差点无法应付

What about the next generation of air-traffic control systems that promise to use GPS satellites and radio transponders to warn all aircraft in a given area about the presence of others?

下一代的空中交通管制系统将会在一个指定区域中使用全球定位系统和无线电应答器来警告所有飞机关于其他飞机的位置。那么这个系统能做到吗？

It also points out that an airline's safety record is not a criterion for renewal of its licence. Nor is the maintenance of airports and air-traffic control systems keeping pace with the industry's expansion.

同时他们指出，航空安全记录并不能作为重新注册许可证的标准，同时维修养护费用和空中交通管制系统能够与航空业的扩张保持一致也不能成为判断的准则。

The pilots had reportedly contacted air traffic control a short distance from their destination of Manaus to say they were turning back.

这些飞行员据报道与空中交通管制联系距离他们的Manaus的目的地不远说他们折回去。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
