And a fast-reconstruction algorithm for aircraft ascending trajectory based on the advance correction of the state value is detailed.

但是，实际飞行过程中，航天器在一些干扰的情况下也很难

Further reflective type measurement can be implemented by THz-TDS. Interface information is obtained from the measured THz waveform reflected from stacked burned and normal porcine skins for simulating partial burned skin. Reflective wave from surface, interface between burned and unburned, back surface of unburned porcine had been correctively and clearly observed. Waveform and time of flight matched well with the original reflected waveform of normal and burned porcine skin.

我们进一步应用兆赫光谱技术来作样品反射式讯号的量测，可以观察到用来模拟部分烧伤的皮肤的由一层烧烫伤以及一层正常的猪皮样品堆叠成的结构中的界面，经由这个模拟结构表面以及内部界面和背面反射的讯号波形都可以正确清楚地判别，所得到反射的波形以及表面和界面间的飞行时间和个别量测正常及烧烫伤样品的结果吻合。

The application of the corrector proposed in a flying simulator shows its validity.

通过某飞行仿真器上的实际应用例子，验证了该方法的可行性和实用性。

Then,the cosine value of central angle between the spacecraft and the descending node is solved by using cosine theorem of spherical geometry to avoid the cumbersome solving process by judging the flight direction of a satellite and the latitude of sub-satellite point in an original calculation model of image motion speeds.

通过球面几何的余弦定理直接求解航天器与降交点相对地心夹角的余弦值，避开了原像移速度计算模型中通过判断卫星飞行方向和星下点纬度来求解航天器与降交点相对地心夹角余弦值这一过程。

Flight crews also face chronic exposure to cosmic radiation, which is a hazard for pregnant women as well.

飞行全体机员也面临着长期暴露在外层空间幅射的危险，这对孕妇也一样是有害的。

Even people on Earth are exposed to cosmic radiation, but the amount is negligible.

大型太阳风暴产生时，不在地球大气保护中的太空人就会暴露在致命剂量的辐射下，搭乘商用客机飞行在高纬区的人们也会暴露在较高的辐射中，即使是在地球上的人们也是暴露在宇宙辐射中，只不过这些辐射量已经是微不足道的。

"I think it's great," says cosmologist and Nobel laureate John Mather of the Goddard Space Flight Center in Greenbelt, Maryland.

来自哥达德宇航飞行中心的宇宙学家、诺贝尔奖得主 John Mather 说：我认为这真是太好了。

Cosmonaut Yury Gagarin becomes the first man in space just 20 days before Shepard is scheduIed to fIy.

宇航员尤里加加林成为进入太空第一人，只比谢泼德的计划飞行时间早了20天。

April 12, 1961, Soviet cosmonaut driving "Vostok 1" spacecraft completed the first ever space flight, the first time in human history, Earth observation from space, the first time in outer space to see the moon looks like.

1961年4月12日，苏联宇航员驾驶"东方1号"飞船完成有史以来的首次太空飞行，在人类历史上第一次从太空观察地球，第一次在外太空看到了月球的模样。

The three astronauts spoke to the press from behind a glass screen at the Hotel Cosmonaut in Baikonur as they are being held in quarantine for fear of being contaminated ahead of their space flight.

当天的记者招待会在拜科努尔的宇航员宾馆举行，三位宇航员在一个玻璃屏幕后回答了记者的提问。为了防止在太空飞行前被感染，目前他们正处于隔离状态。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
