太空

The six-hour spacewalk is the first of five planned for Discovery's mission.

六小时次太空行走是&发现&号此次飞行任务安排的5次太空行走的第一次

Nasa's next shuttle mission is a servicing trip to the hubble telescope due to lift off in may.

美国太空总署的下一个太空梭计划，是预计在五月升空，前往哈柏太空望远镜一游。

The mission promises to be very busy for the entire crew, as five spacewalks, two of which will have Good leaving the shirt-sleeved environment of the shuttle to perform work on the Hubble Space Telescope, are in the offing.

这次任务对整个乘员组来说会非常忙，在5次太空行走中，哥德将离开舒适的飞船环境进行2次太空行走，进行哈勃维修任务。

Through the project, domestic GPS receiver/chip manufacturers have been surveyed, GPS signal simulations for coverage, signal quality, tracking loop, and positioning accuracy have been performed, a GPS receiver prototype has been implemented to overcome limitations due to high altitude, high speed, rapid Doppler variations, and vehicle motions, performance tests with other receivers have been conducted, and, finally, a specification for the development domestic spaceborne GPS receiver has been recommended.

本计画之主要成果包括完成国内相关厂商之资料收集、访查、与分析建议，完成太空级GPS接收机之模拟分析包括讯号观测、讯号品质、追踪回路、定位计算等，完成GPS接收机工程雏形系统之建立并针对高度/速度限制、都卜勒变化、快速撷取、与轨道计算进行韧体发展，及进行GPS接收机工程雏形系统与现有GPS接收机之功能与性能测试，及完成国产太空级GPS接收机之规格建议。

Even before the Apollo programme fell to earth, we had managed to internalise much of the space age's outward?bound rhetoric.

即便在阿波罗登月计划制定之前，我们内心存有许多有关太空时代对于外太空的溢美之词。

The still, fixed colours of the stars; to watch from the outside as lightning forked through a weather front; tomeasure the spiders' webs of cities against the immense blue of ocean and the matt black of far space.

他们可以看到恒星寂静的固定的色彩，可以从外太空看到闪电交织着穿过大气层，地球上的城市星罗棋布，映衬着蔚蓝的海洋和其后更遥远深邃的太空。

It allowed them to observe the still, fixed colours of the stars; to watch from the outside as lightning forked through a weather front; to measure the spiders' webs of cities against the immense blue of ocean and the matt black of far space.

他们可以尽情欣赏繁星静若处子般不变的色彩，从外太空见识闪电如何刺穿锋面，在广阔无垠的蓝色海洋和一望无际的暗黑色太空衬托下历数各地城市所编织成的蛛网。

Two of the astronauts will enter the orbital module, put on EVA spacesuits and prepare for the spacewalk.

2名宇航员将进入轨道舱，穿上太空外活动宇航服准备太空行走。

And on this flight, one of those space travelers is to carry out China's first spacewalk, also known as extravehicular activity, or EVA for short.

此次太空飞行，1名宇航员将迈出中国太空行走的第一步，也称作太空舱外活动。

Most of these repairs could not be effected in deep space or even in low orbit without the constant threat of enemy sneak attacks and the overwhelming logistical problems that extended extravehicular activity would entail.

大多数修理无法在太空中有效的完成，甚至在没有敌人不断偷袭的低位轨道也无法很好的修理，毕竟，有些象太空外作业是受到限制的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
