| 1. | Natural space radiation 自然空间辐射 |
| 2. | Finally , transient temperature distributing is simulated . thermo - soakback phenomena , electrical heating efficiency of catalyst bed and outer space radiation are analyzed 分析了热回浸现象、催化床电加热效能以及外空间辐射换热等问题。 |
| 3. | Consequently , in addition to uv protection , what really matters is how resistant a microbe is to all components of space radiation and how quickly the life - bearing meteorite moves from planet to planet 于是,除了紫外线防护之外,真正的问题在于,细菌如何防御宇宙辐射中所有的成份,以及带有生命的陨石如何从某一行星迅速移动至另一行星。 |
| 4. | The space agency plans to save $ 344m ( ? 198m ) next year by halting research aboard the international space station into the effects of space radiation on humans , the design of life support systems , and advanced environmental controls 太空机构计画明年藉著停止登上国际太空站研究宇宙辐射对人的影响、维生系统的设计以及进阶环境控制,省下3亿4千4百万美元。 |
| 5. | The first man to walk on the moon noted that scientists must develop better onboard spacecraft technology and stronger protection shields from harmful space radiation before a manned flight to the red planet can be accomplished . " it will certainly be 20 years or more before that happens , " armstrong said during a global leadership forum 据美联社9月6日报道,阿姆斯特朗表示,在完成登陆火星的载人飞行之前,科学家们必须研发出更好的机载太空船技术以及更强的阻挡有害太空辐射的防护装置。 |
| 6. | The rate of single event upset ( seu ) for space - based missions has been predicted by means of ground - based particle accelerator test and simulation calculation based on models of space radiation environment and the interaction of ions with the microelectronic device 我们采用的方法是用地面重离子加速器模拟实验和计算机模拟空间辐射环境进行单粒子翻转率预估计算。引发单粒子翻转的空间高能带电粒子环境包括银河宇宙线,太阳宇宙线和地球辐射带中的高能质子及重离子。 |
