空域

To Image pretzels and Gaussian noise, and the spatial filter!

给图像加椒盐和高斯噪声，以及空域滤波！

4 To prevent undesirable ACAS TA/RA triggering in RVSM airspace and since most civil aircraft use FEET as the primary altitude reference with a minimum selectable interval of 100 feet.

2.4 为防止在RVSM空域内触发TCAS虚警，大多数飞机使用英制单位且高度表设置最小刻度为100英尺。

Synchronization markers limit the propagation of spatial errors within video frames.

同步标记可限制空域差错在视频帧之间传播。

The model was simulated by Matlab. The control sequences of different flow proportionality factor with feedback gain were compared. Through comparing sample data, the result reveals that air traffic flow in the airspace unit has been improved.

利用Matlab对系统进行了仿真，对不同流动比例系数下得到的控制序列和反馈增益进行比较，通过采样数据的比较，得出的结果显示，空域单元的飞行流量得到改善。

In 1960, the FAA began successful testing of a system under which flights in certain positive control areas were required to carry a radar beacon, called a transponder, that identified the aircraft and helped to improve radar performance.

1960年，联邦航空局进行了一项成功的试验，在特定管制空域内的航空器安装了一个称作应答机的雷达信号装置。它能够用于航空器识别并增强雷达的性能。

On the base of the theory, phenomenon of optical diffraction from a single slit, round aperture, grating, and so on are analyzed according to the ideal of wave-front filtering.

在此理论基础上，根据波前滤波思想，对单缝、圆屏、光栅等衍射现象进行了分析；同时也分析了空域滤波、空频域滤波、光学成像系统。

The area is in the warm temperate continental climate zone; the sleety weather is little, so there are about 310 days suitable for flying every year.

处于北京、青岛、济南三大航空港的中间地带，华东、东北地区最重要的三条航线都避开了航空产业园的空域，20公里范围内无高大空中障碍物；属暖温带大陆型气候，雨雪天气少，无霜期短，年适合飞行日可达310天。

There are various fast algorithms of calculating diffraction integral in space range and frequency range.

对衍射积分的计算，可以采用空域数值计算及频域的多种快速算法。

Based on the decomposition of the space time eigenstructure of signals,a novel wideband spectral correlation space time DOA matrix method is proposed in this paper to estimate the 2 D DOA of wideband signals .

该方法利用信号的循环平稳特性实现了对宽带信号的有效处理，同时通过空时变换将传统的一维空域处理拓展到了二维空时处理，更充分地利用了信号的时域特征，从而大大简化了阵列结构，提高了算法的性能。

In this method,edges are preserved and interpolations are performed within each subregion to avoid smear across edges.

笔者提出了一种新的结合边缘检测的空域内插办法，能在保留边缘的情况下根据边缘对图像的划分对图像进行分区内插。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
