单词 Dyson Spheres
释义

Dyson Spheres

原声例句
双语版 TED-Ed 演讲精选

The key to harnessing this power may lie in a structure devised by physicist Freeman Dyson, known as the Dyson sphere.

开发利用这一能量的关键,也许就在于一个由物理学家弗里曼·戴森设计的,被称为“戴森球”的结构。

传说之境

And one of the more interesting theories was that we were witnessing the construction of a giant alien megastructure called a Dyson sphere.

其中一个更有趣的猜测理论是,我们正见证着一个巨大的外星巨型结构的建造——戴森球。

传说之境

So, the logical end step for maximum energy harvesting is to harvest it directly from the Sun from one of three different types of Dyson spheres.

因此,为了获取最多的能源,按逻辑推理的最终步骤是,直接从太阳上收集能量,从三种不同类型的戴森球体中选择一种。

图为戴森球的一种变体。这种大规模人造物会大幅度改变恒星的光谱。

戴森环是戴森云最简单的结构。图中轨道半径为1天文单位,太阳能收集器的直径为1.0×107千米(约25倍地月距离),收集器中心围绕圆形轨道分隔3度均匀分布,图像观测点距离中心恒星2天文单位。图按照比例绘制。
多戴森环是戴森云的一个相对简单的结构。图中轨道半径为1天文单位,太阳能收集器的直径为1.0×107千米(约25倍地月距离),环上收集器中心分隔3度均匀分布,环与环之间分隔15度均匀分布。图像观测点距离中心恒星约2.8天文单位。图按照比例绘制。

戴森球英语:Dyson Sphere)是弗里曼·戴森假想出的包围母恒星的巨大球形结构,它可以捕获大部分或者全部的恒星能量输出。戴森认为戴森球是长期生存技术文明对于能量需求增长的必然需求,并认为寻找其存在的证据可以引导发现的先进和智能的外星生命。不同类型的戴森球和它们的能量收集能力将对应于在卡尔达肖夫指数水平上的技术进步。

自从该概念提出以后,诸多科幻作品里提出的包围恒星的人工建筑都被冠以“戴森球”之名。后续的设想认为戴森球上不仅有太阳能电站,还有人类殖民地和工业基地存在。

Dyson sphere 戴森球

(重定向自Dyson Spheres)
A Dyson ring — the simplest form of the Dyson swarm — to scale. Orbit is 1 AU in radius, collectors are 1.0×107 km in diameter (10 Gm or ~25 times the Earth–Moon distance), spaced 3 degrees from center to center around the orbital circle.
A relatively simple arrangement of multiple Dyson rings of the type pictured above, to form a more complex Dyson swarm. Rings' orbital radii are spaced 1.5×107 km with regard to one another, but average orbital radius is still 1 AU. Rings are rotated 15 degrees relative to one another, around a common axis of rotation.
A Dyson bubble: an arrangement of statites around a star, in a non-orbital pattern. As long as a statite has an unobstructed line-of-sight to its star, it can hover at any point in space near its star. This relatively simple arrangement is only one of an infinite number of possible statite configurations, and is meant as a contrast for a Dyson swarm only. Statites are pictured as the same size as the collectors pictured above, and arranged at a uniform 1 AU distance from the star.
A cut-away diagram of an idealized Dyson shell, a variant on Dyson's original concept, with a radius of 1 AU.

A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures most or all of its power output. The concept was first described by Olaf Stapledon in his science fiction novel, Star Maker (1937), and later popularized by Freeman Dyson in his 1960 paper, "Search for Artificial Stellar Sources of Infrared Radiation". Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival. He proposed that searching for such structures could lead to the detection of advanced, intelligent extraterrestrial life. Different types of Dyson spheres and their energy-harvesting ability would correspond to levels of technological advancement on the Kardashev scale.
