Impact on capability of military aviation surveillance due to performance of our existing navigation star is f

通过飞行试验，验证了基于双星系统进行军事航空监视的可行性，证明了在低空空域和地基雷达覆盖不到的区域有可能利用双星系统为飞机提供位置服务、精确授时和短报文通信联络。

In the latter part, we discuss some classical algorithms of conventional AMTI and STAP and present a new method to combine space conventional beamformer with the maximum improve factor AMTI filter.

在自适应动目标指示部分，讨论了常规AMTI处理和空时联合自适应处理的各种算法，提出一种将空域常规波束形成与最大改善因子AMTI滤波器相结合的处理方法并进行了仿真验证。

The ability to put combat aircraft, or support helicopters, into the air over international waters or inland during coastal operations is likely to be a key factor in determining success.

在沿海军事行动中将作战飞机和支援直升机投入国际海域上空和内陆空域的能力，仍旧是决定行动成功与否的关键因素。

The correlation coefficient of weak correlated random error is calculated using least squares method, so the random errors ultimately are classified as correlated errors and misrelated errors.

然后进行了目标运动模型假定及命中点和误差的坐标平移，并对未来空域窗体制下的毁伤概率进行了数学分析与数字仿真。

The algorithm first makes motion estimation in spatial/temporal domain and obtains motion vectors for each prediction block.

该文提出的算法先在时空域进行运动估计，得到预测块的运动矢量。

NATS is the UK's largest provider of airport, oceanic and en-route air traffic control.

英国国家航空交通服务有限公司，简称&NATS&，是英国最具规模的航空交通管制服务提供者，专责提供机场，太平洋上空及英国空域的空管服务。

The function of the control tower is to issue clearances and information to aircraft and vehicular traffic operating on runways, taxiways, and other designated areas of the airfield and to aircraft operating in assigned airspace areas.

塔台管制的作用是为航空器和在跑道、滑行道和其他指定的小机场上运行的交通工具以及在指定空域运行的航空器发布许可指令和情报信息。

The algorithm suppresses background and enhances targes by morphological Tophat transform in spatial, and the image sequences are processed with the 1-D wavelet transform in order to separate the target from background in temporal.

在空域上，通过灰度形态学Tophat变换抑制背景、增强目标；在时域上，对红外图像序列连续四帧进行沿时间轴一维小波变换，实现目标和背景的分离。

In the meanwhile, the TS characteristics of a scattering particle and their relationship are studied when it is passing through the scattering area, In addition to this, the distribution function of particles' shape is defenited in terms of math's method and a new method is putout of which the distribution of particles' shape is captured in according to the power spectrum and spectral distribution characterist of light scattering and finally, the utility of the perturbation ameliorating method and the effect of the particles' shape is modified, so far, the accuracy of measurement of the particles' size is improved effectively.

对此，本文在以Mie散射理论为原理，依据前向接收器接收的前向散射光信息以获取微粒大小信息的测量基础上，对微粒穿越光敏区时的时域与空域的特征以及相关性开展了研究，从数学上定义了微粒的形体分布函数，提出了一种依据光散射功率潜和频谱分布特征来获取微粒形体分布信息的方法，完善了微扰修正理论的应用性，有效地改善了形体的影响问题，从而可提高微粒粒度分布测量结果的准确性。

For example, in the research of the space distributing structure of a certain pollutant in the atmosphere, space variation of the pollutant in the soil, design of pollution monitoring net of groundwater, and the v...

首先概述了研究的目的及意义，阐述了克里格方法在水环境系统中的应用情况，然后介绍了克里格方法的基本理论和方法，进而重点讨论了纯时间域和时空域克里格的性质和建模方法，最后将纯时间域克里格方法应用到地表水评价中，预测了某湿地未来几年的水质变化趋势，验证了该模型方法在地表水评价的水质预测方面是可行的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
