9 月 26 日，拉脱维亚银行将发行一枚纪念币，致力于纪念科学在我们生活中的作用以及科学家们坚持不懈地寻求人类未来问题的答案。

The "Energy Coin" tells us about the biggest challenge of the modern world – the search for an inexhaustible source of energy to protect natural resources and achieve a balance between the whims of our age and the interests of future generations.

“能源币”告诉我们现代世界面临的最大挑战——寻找取之不尽、用之不竭的能源来保护自然资源，并在我们这个时代的突发奇想和子孙后代的利益之间取得平衡。

When developing the design of the coin, world-renowned designer Germans Ermičs consulted scientists to find the visual solution for depicting the fundamental laws of physics that allow for the existence of an almost limitless source of energy – the nuclei of light chemical elements. When smaller nuclei combine to form larger ones, a tremendous amount of energy is released in the form of heat, but to start and maintain this fusion reaction, a temperature of millions of degrees and the pressure to hold the matter together for a long enough time are needed. In nature, such extreme conditions occur in stars.

在设计硬币时，世界著名设计师德国人埃尔米奇斯咨询了科学家，寻找视觉解决方案来描绘基本物理定律，这些定律允许几乎无限的能源——轻化学元素的原子核的存在。当较小的原子核结合形成较大的原子核时，大量的能量以热的形式释放出来，但为了启动和维持这种聚变反应，需要数百万度的温度和将物质长时间保持在一起的压力需要。在自然界中，这种极端条件发生在恒星中。

It is the fusion of hydrogen nuclei that powers the Sun and thus indirectly drives all the renewable energy sources on Earth. Nuclear fusion energy has two major advantages: virtually inexhaustible fuel resources and a neutral impact on the climate.

氢核的聚变为太阳提供动力，从而间接驱动地球上所有的可再生能源。核聚变能源有两大优点：几乎取之不尽用之不竭的燃料资源和对气候的中性影响。

Turning the principle of nuclear fusion into a practical and widely available technology is a major scientific and engineering challenge that tens of thousands of researchers around the world have already been working on for a long time. Their task is the mission of Prometheus – to bring down the spark of the Sun from the heavens to serve people. The Treaty of the European Atomic Energy Community is one of the oldest European cooperation frameworks. Latvian scientists also participate in it with their contribution to the creation of the prototypes of the world's largest nuclear fusion reactors – ITER and its successor DEMO.

将核聚变原理转化为实用且广泛可用的技术是一项重大的科学和工程挑战，全世界数以万计的研究人员长期以来一直在致力于这一挑战。他们的任务就是普罗米修斯的使命——从天上带下太阳的火花来服务人类。 《欧洲原子能共同体条约》是欧洲最古老的合作框架之一。拉脱维亚科学家也参与其中，为世界上最大的核聚变反应堆原型的创建做出了贡献——ITER 及其后继者 DEMO。

The silver collector coin issued by Latvijas Banka depicts the particles involved in the hydrogen fusion reaction. The beads depicted on the coin represent elementary particles that make up nuclei: the silver hollows are neutrons, while the gold-plated beads are protons. Hydrogen nuclei with one proton are the raw materials, while a helium nucleus with two protons and a free neutron are the products of the fusion reaction.

拉脱维亚银行发行的银质收藏币描绘了参与氢聚变反应的粒子。硬币上描绘的珠子代表构成原子核的基本粒子：银色空心是中子，而镀金珠子是质子。具有一个质子的氢核是原料，而具有两个质子和一个自由中子的氦核是聚变反应的产物。

The main conditions for nuclear fusion are high temperature and pressure. In stars, the conditions for nuclear fusion are ensured by a strong gravitational field, while in nuclear fusion reactors, the hot plasma is held together by special magnetic fields. The arrangement of lines on the coin resembles both the magnetic fields of large space objects and the stylised cross-section of a toroidal fusion reactor – the so-called tokamak. The relief of the coin with a recess in the centre also echoes the gravitational potential near a star or a black hole.

核聚变的主要条件是高温和高压。在恒星中，强大的引力场保证了核聚变的条件，而在核聚变反应堆中，热等离子体由特殊的磁场结合在一起。硬币上的线条排列类似于大型太空物体的磁场和环形聚变反应堆（即所谓的托卡马克）的程式化横截面。硬币中央凹陷的浮雕也与恒星或黑洞附近的引力势相呼应。

Honouring the contribution of Latvian scientists to the research of nuclear energy, the University of Latvia, in cooperation with Latvijas Banka, is organising a lecture dedicated to nuclear fusion "How to Tame the Energy of the Future" and the presentation of the Energy Coin. At the event, the lecture will be delivered by researcher of the Europe's largest nuclear fusion experiment project ITER (France) Bertrand Roques, while the author of the Energy Coin and artist Germans Ermičs will delve into the process of creating its design. An expert discussion moderated by quantum physicist and Professor of the University of Latvia Vjačeslavs Kaščejevs is also to be held at the event to address the future of Latvia's nuclear fusion and the synergy of science and art. Anyone interested is invited to attend the event free of charge at 14:00 on 26 September, at the House of Nature of the University of Latvia in Riga, Jelgavas iela 1.

为了表彰拉脱维亚科学家对核能研究的贡献，拉脱维亚大学与拉脱维亚银行合作，正在组织一场专门讨论核聚变的讲座“如何驯服未来的能源”并介绍能源币。活动中，欧洲最大核聚变实验项目ITER研究员（法国）Bertrand Roques将主讲，能源币作者、艺术家Germans Ermičs将深入探讨其设计过程。活动中还将举行由量子物理学家、拉脱维亚大学教授 Vjačeslavs Kaščejevs 主持的专家讨论会，讨论拉脱维亚核聚变的未来以及科学与艺术的协同作用。欢迎感兴趣的人士免费参加 9 月 26 日 14:00 在里加拉脱维亚大学自然之家举行的活动，地址：Jelgavas iela 1。
