发射地

Pyongyang keeps trying to launch a satellite which the US and Japan perversely insist is some kind of long-range missile but it has not managed to get one into orbit. It tried in 2006 but, far from reaching Alaska as the Americans claim it can, it disintegrated 35-40 seconds after launch, plopping harmlessly into the sea.

朝鲜政府一直试图发射一颗卫星--美国和日本执迷不悟地坚持认为这是某种远程导弹--但尚未成功将卫星送入轨道。2006年朝鲜进行了试射，然而，卫星非但没有像美国人声称的那样到达阿拉斯加，反倒在发射升空35至40秒后便爆炸解体，落入大海，没有造成任何破坏。

Transmitter is composed of 555 core multivibrator, by changing the oscillator frequency to adjust the frequency of infrared emitter, and can adjust the resistance to reduce the infrared signal duty cycle to increase as much as possible infrared the scope of protection.

详细说明：发射电路是以555为核心组成多谐振荡器，通过改变振荡器的工作频率来调节红外发射器件的工作频率，且可以通过调节电阻来减小红外信号的占空比，从而尽可能地增加红外防护的范围。

The specific content of man-made earth satellite motion theory, power of observation and owned satellite operator, observation equipment and the establishment of such a number of observation points the content of .20 century, 60-70 years, have been used as a weather observation satellite launched high-altitude balloon, as the satellite observed the law of geometric measurement objectives of the United States launched TRANSIT .80 era satellites, it has several flights along different directions through the ring of satellites to address at any time, there will be a satellite-observable problems.

具体的研究内容有人造地球卫星运动理论、动力式卫星的观测及归算、观测仪器和观测点的设立等多项内容。20世纪60—70年代，曾用为气象观测发射的高空气球卫星，作为卫星几何测地法的观测目标。80年代美国发射子午仪卫星，它有几个沿不同经圈方向飞行的卫星，以解决任何时候都会有一颗卫星可观测的问题。

By designing the mould to change the propellants model frame, selecting differentmaterials as propellant seal layer agents, studying the preparation technics, we havepreferably solved the PSS seal layer pressurize and combustion disciplinarian problem, andobtained the remarkable increasing burning surface effect.The practical increment ofΓvalue reachs 3.2 upwards conducting closed bomb firings, comparing with 19 holepropellants—the best progressivity burning in the present, whose practical increment ofΓvalue is 1.2, the PSS amplitude ofΓvalue exceeds 2.5 times.

通过药型结构和模具的设计、端面密封材料的选择和制备工艺的研究，较好地解决了PSS发射药的端面密封和燃烧规律控制问题，获得了显著的增面性燃烧效果，密闭爆发器实验中燃气生成猛度的实际增量达到了3.2以上，与目前增面性最好的19孔发射药实际增量的1.2左右相比，增幅超过了2.5倍。

This reporter's visit to Shah-e-Nehru, with Hazara tribal elders and a few local police, ended in headlong flight under a volley of rocket-propelled grenades and sustained gunfire from mountains held by the Kuchis.

笔者前往Shah-e-Nehru村时，同行者里有哈加拉族的长者，还有一些当地的警察。我们轻率地选择了坐飞机，结果遇到了火箭发射器发射的榴弹与炮火组成的枪林弹雨。

This model builds up the relationship between the levitation capabilities and the geometric parameters of a single-axis acoustic levitator, and proves to be successful in predicting resonant modes, Hm ( m =1, 2, 3, 4), and in explaining the axially symmetric deviation of the levitated samples near the reflector and emitter.

该模型揭示了声悬浮性能和以声波长为参考的悬浮器几何参数之间的本征关系，成功地预测声场的谐振模式 Hm ( m =1， 2， 3， 4为模式数， Hm 为反射端-发射端谐振间距)，并解释了反射端和发射端附近的悬浮样品偏离对称轴的实验现象。

The enhancement of the field emission ability is attributed to the fact that the field-induced screening effect can be effectively avoided due to the widely spaced intervals that exist between the unoriented nanowires.

非取向生长ZnO纳米线薄膜场发射能力的增强归因于其所具有的稀疏结构避免了强场作用下屏蔽效应的产生，有效地提高了薄膜场发射的电流密度。

First of all, it is worth noting that the United States could undoubtedly destroy the missile now that it is being fueled in plain view on the launching pad, but America has disavowed any interest in doing so. It has also decided not to intercept the missile during launch either; when asked if U.S. would consider doing so, the American defense secretary dismissed the idea earlier this week, explaining "I would say we're not prepared to do anything about it".

首先，当导弹无遮无掩地在发射台上加注燃料的时候，美国无疑是能摧毁它的，可美国却对这一做法没有兴趣，而且还决定，即使在发射期间也不对其进行拦截；本周早些时候，当被问到美国是否有考虑采取此类行动时，美国国防部长反驳了这种提法，他解释道：其实我要说的是，我们不准备为其采取任何行动。
