发射

After all, a Katiusha completely unmasks itself when firing, it raises a large pillar of smoke. That's why we tried to fire only during the dark time.

毕竟，&喀秋莎&发射时是完全暴露的，且产生很多烟，这就是为什么我们只在黑暗中发射。

The 7AM launch of the four stage Air Force Minotaur I rocket took place at NASA's Wallops Flight Facility on Virginia's eastern shore.

这座在早上七点发射的四节式美国空军牛头人一型火箭，发射地点是位在维吉尼亚州东岸的美国太空总署Wallops飞航基地。

2009.7.8早晨6：26，弗吉尼亚州的瓦勒普岛、美国宇航局的瓦洛普飞行中心，NASA成功演示了用于未来太空发射任务的替代性系统——最大发射失败救援系统，简称MLAS。

The first, flight test FTV-3, was performed on 6 March from the Wallops Flight Facility Test Range in Virginia; it was followed on 28 March by FTV-4, launched from the Leahy-class cruiser USS Richmond K Turner.

首次飞行试验FTV-3，于3月6日从位于弗吉尼亚的沃洛普斯飞行研究所实验场发射；然后于3月28日进行了代号FTV-4实验。从莱希级驱逐舰'特纳号'上发射。

Both crystal and ceramics show typical Ce3+ absorption bands at 230,340 and 460 nm and a 540 nm emission peak.

Ce：YAG晶体和陶瓷都具有位于230，340和460 nm波段的Ce3+离子的特征吸收带和540 nm附近的发射峰，但Ce：YAG晶体同时存在296和370 nm的色心吸收，其发射峰位于398 nm，而透明陶瓷中不存在。

Ablation-controlled arc plasma generator is a critical component of energy transition in electrothermal -chemical launch system. Systematic research on piccolo injector is carried out in the dissertation. The main points are as follows: 1 The nature of discharge of piccolo injector is discussed.

本文以国防科技重点预研项目&电热化学炮总体与发射技术研究&为背景，对电热化学炮中电热转换的核心部件—中心电弧等离子体发生器，进行了理论分析、工程设计和实验研究，将中心电弧式等离子体发生器成功地应用到电热化学发射实验中，主要内容包括以下几个方面： 1。

Firstly, this paper gives a brief introduction on the principles and the form of GPS system; On the base of the demand of the moving bi-static/multi-static radar measuring real-time position of the transmitter and the receiver, separately the application of GPS in the radar is discussed; Formulas of the distance and the azimuth the receiver relative to the transmitter are ...

论文首先简单介绍GPS的工作原理及其系统组成；根据在运动平台上的双/多基地雷达需要对发射站和接收站位置进行实时定位的要求，研究GPS在该雷达中的应用；根据GPS提供的接收站经纬度信息，推导了接收站相对于发射站的距离和方位角的计算公式；讨论了GPS定位误差对接收站定位和对目标定位精度的影响，结果表明GPS可以满足该雷达系统的要求。

The experiment shows that CSELF is potentially valuable for earthquake research and prediction. It is also found that the recorded electric and magnetic component amplitude of CSELF signal varies depending on the distance and azimuth of the observatories relative to the transmitter. These amplitudes decline with increasing distance between observatory and transmitter faster within some space extent than those outside the extent. It may be easier for magnetic components to have higher ratio of signal to noise than for electric component.

试验还发现，各地震台站和流动测点观测的CSELF信号的强度，与台站或者测量的电、磁场分量相对于发射源的距离、方位有明显的关系；发现在离开发射源的相对近区，场强随距离的衰减，比在相对远区更快；发现接收磁场信号比电场信号较易获得更高信噪比的数据。

In order to evaluate aiming error of missile on the warship or on the submarine, including the error of warship position, the error of reference azimuth and the error of transfer measurement given by the navigation system, and try to divided them from the general error, it is highly important that we estimate and evaluate missile system of mobile bedding launching.

为了评估从舰船／潜艇上发射导弹的瞄准误差，包括舰船导航系统给定的船位误差、基准方位误差及其传递测量误差，并试图把它们从总的瞄准误差中分离出来，这对于动基座发射导弹武器的瞄准精度的评价极为重要。

The previous week, they passed close to the rocket base in Sichuan province where China had launched its first lunar probe - part of the country's ambitious space programme.

在先前的一个星期，他们经过了靠近位于四川省境内的火箭发射基地的地区，在那里中国发射了第一个月球探测器——这是中国雄心勃勃的空间计划的一部分。

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％。
