| 1. | This value has been confirmed by observation with an accuracy of perhaps 20 percent .
这个数值已为观测所证实，准至百分之二十。 |
| 2. | Inside the observatory a team of scientists closely follow the debris
在观测所里，科学家正紧盯著残骸物。 |
| 3. | Those calculations have been corroborated by measurements of primordial hydrogen , helium and lithium in the universe
那些计算结果已经由对宇宙最初阶段氢、氦及锂含量的观测所确认。 |
| 4. | As clouds may obstruct the observation , the image is usually constructed from a number of satellite observations over the same region
由于云层阻碍观测，图像一般是由数次同范围卫星观测所合成的。 |
| 5. | As clouds may obstruct the observation , the image is usually constructed from a number of satellite observations over the same region
由于云层阻碍观测，图像一般是由数次同范围卫星观测所合成的。 |
| 6. | Separating rfi from true signals from the sky is a persistent challenge for all radio - telescopic observations , including seti
将真实信号从频率干扰中分离出来是包括seti在内的所有射电观测所面对的长期挑战。 |
| 7. | The estimate is derived from elementary probability and does not even assume speculative modern physics , merely that space is infinite ( or at least sufficiently large ) in size and almost uniformly filled with matter , as observations indicate
这项估计甚至无需用到深奥的近代物理，只需假设空间是无限大（或至少要够大） ，而且物质几乎均匀地分布其中（一如我们的观测所见） ，然后再用基本的机率，就可以导出来了。 |
| 8. | The signal / data obtained by measurement or observation usually contain two parts : one part is useful which has a direct or indirect relation to the research object , called information . and the other part is interferential has no relation to the research object , called noise
通过测量或观测所获得信号或数据通常包含两个部分：其一是与所研究的对象存在直接或间接关系的有用部分，称为信息；另一部分是与所研究的对象无关的干挠部分，称为噪声。 |
| 9. | The possible influence of the global warming to storm surge frequency has been one of the concerned questions at present for researchers . some of them consider that the frequency will increase according to the results of observation and simulation , but some others do n ' t agree to it . to verify the speculated conclusions , the coastal storm surge frequency in middle jiangsu province during the warm period of middle holocene is discussed in this thesis
风暴潮频率在全球气候变暖后的可能变化已引起了广泛的关注，而目前研究者们通过模拟与观测所获得的结论并不一致，基于此，本文从地质时期气候冷暖变化与热带气旋频率变化之间的关系对这一问题作了验证与探讨。 |
| 10. | Prof . sun kwok , chair professor and dean of science at the university of hong kong , believes that the rings seen in hubble 12 are related to the shaping of the nebula : " a series of fast , directional , periodic pulse ejections from the star carve out the remnants of previously ejected material and create the hourglass shape
郭教授相信，这些从哈勃12号星云观测所见的层圈，和星云的形成不无关系。一连串高速周期性有方向性的爆发，将哈勃12号星云雕刻成这漏斗形状。 |
