辐射的

About 4,000 light-years from planet Earth toward the nautical constellation Puppis, the nebula spans over a light-year and is energized by ultraviolet light from the central star.

这个星云位在航海星座的船尾座内，离地球约有四千光年远，大小略高於一光年，在中心星紫外辐射的激发下发光。

You may know that the sun is the principal source of radiant energy that we experience daily.

你可知道，太阳辐射的主要来源能源我们每天的经验。

Of these, the only quantity that can be measured is that which is radiated through the earth.

当然， 地层中弹性辐射的能量是唯一可以被测量的。

However, it is important to put the risks from radiation into perspective.

不过，这是很重要的，把风险从辐射的角度来看。

In addition, the radiative lifetime decreases while the excitation power was increased.

另外，当激发光强度增加时，辐射的生命周期呈现减弱的趋势。

With the help of special radio telescope, the intensity of radiation can be measured in different parts of the sky.

借助于专门的射电望远镜，就可以测量天空中任何地方辐射的强度。

Treatment of disease with radiation,especially by selective irradiation with x - rays or other ionizing radiation and by ingestion of radioisotope s.

放射疗法用放射进行的疾病治疗，尤指用X射线或其它电离辐射的有选择放射和吞下放射性同位素

Secondly, the method of calculation of stray radiation in well-baffle optical system of space remote sensor is presented, and the software is established.

其次，给出了航天遥感器完善遮光光学系统的杂散辐射的计算方法，并形成了软件。

It could stimulate the growth of animals and plants, prolong the life of organisms, promote the reproductive capability, excite the immunological system, and also have an antitumor effect.

低剂量电离辐射的"Hormesis"现象可以在许多方面观察到，包括刺激动物、植物生长发育、延长生物体的寿命、提高生育力、免疫刺激作用和抗癌作用。

In this article the properties of resonance cavity, operating condition, and radiation output of optical pumping laser are discussed.

本文讨论了光量子放大器的谐振腔、振荡过程和输出辐射的性质。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
