Chinese researchers say they have built an artificial intelligence (AI) robot that can carry out chemical reactions to produce oxygen from water on Mars. 

中国研究人员表示，他们已经建造了一种人工智能（AI）机器人，可以在火星上进行化学反应，从水中产生氧气。 

The system could be another way for space travelers in the future to make much-needed oxygen on Mars. Humans visiting the Red Planet will need oxygen to support life. The gas could also be used to make rocket fuel, which is difficult to transport to space. 

该系统可能成为未来太空旅行者在火星上制造急需氧气的另一种方式。 访问这颗红色星球的人类需要氧气来维持生命。 这种气体还可用于制造难以运输到太空的火箭燃料。 

Scientists have already established from multiple studies that Mars contains large amounts of water. Most of the water exists in the form of ice. Developers of the new robot system in China say it can be used to release oxygen from the planet’s water supply. 

科学家通过多项研究已经确定火星含有大量水。 大部分水以冰的形式存在。 中国新型机器人系统的开发商表示，它可以用来从地球的供水中释放氧气。 

Scientists at the University of Science and Technology of China in Hefei led the research. The team explored whether an AI robot could use materials found on Mars to produce catalysts to break down water and release oxygen. A catalyst is a substance that permits certain chemical reactions to happen. 

合肥中国科学技术大学的科学家领导了这项研究。 该团队探讨了人工智能机器人是否可以使用火星上发现的材料来生产催化剂来分解水并释放氧气。 催化剂是一种允许某些化学反应发生的物质。 

Experiments were carried out on meteorites that either came from Mars or contained materials similar to the Martian surface. The researchers said the “robot chemist” first used an acid and chemical mixture to separate and examine materials contained in the meteorites. It identified several different metallic elements, including iron, nickel, magnesium and aluminum. 

对来自火星或含有与火星表面类似物质的陨石进行了实验。 研究人员表示，“机器人化学家”首先使用酸和化学混合物来分离和检查陨石中所含的材料。 它鉴定出了几种不同的金属元素，包括铁、镍、镁和铝。

The machine then worked to identify different molecules that could be produced from meteorite materials. The team said the system found more than 3.7 million possible molecule combin
