宇宙温度

大爆炸最初那一刻，宇宙温度极高，密度极大，蕴含了巨大的能量。

In the earliest moments of the big bang , the universe was so hot and dense . There were great amounts of energy .

将温度概念推广到均匀各向同性的辐射场，导出了辐射场温度与辐射能密度的关系，并对宇宙背景温度给出解释。

Extends the concept of temperature to the uniform and isotropic radiative field , deduces the relation between radiative field temperature and radiation energy density , and interprets the cosmic background temperature .

整个宇宙的最低温度是多少呢？

How cold is the lowest estimated temperature in the entire universe ?

对于科学家，她要讲的可能是技术细节问题。例如宇航服是如何保护宇航员免遭宇宙致命极端温度的侵害。

To scientists , she might provide technical details on such topics as the design of spacesuits that protects spacemen from the deadly temperature extremes of space .

宇宙中存在着温度为3K的背景辐射，故在宇宙中太阳的电磁辐射不会无穷远。

The range of the electromagnetic radiation from the sun is not infinite as the background radiation of the cosmos is 3K .

然而，对宇宙微波背景辐射温度的测量显示宇宙的结构也许有某种系统的规律。

However , measurements of the cosmic microwave background radiation temperature suggest that its structure may have some systematic order .

通过比较宇宙大爆炸的温度和负温度的概念，对自然界中热平衡态下可能达到的最高温度和负温度的物理意义进行了讨论。

By making a comparison between the concepts of temperature and negative temperature in the cosmic explosion , this paper discusses the physical meaning of the maximum temperature and the negative temperature which can be achieved in the natural thermal balance condition .

采用共形平直方法，确定了黑洞内外视界和宇宙视界的准确位置，得到了黑洞外视界和宇宙视界的温度。

The exact locations of the cosmological , outer and inner horizons of the black hole and the radiation temperatures of the first two horizons are determined by using conformal flat method .

X射线将光子散播在宇宙微波背景中，结果在一种被称为“运动学SZ效应”的作用下改变了宇宙微波背景的温度。

The X-rays scatter photons in the CMB , shifting its temperature in an effect known as the kinematic Sunyaev-Zel'dovich ( SZ ) effect .
