对能源的需求和对环境的关切促使人类探索新的途径.在诸多新能源中以核聚变较为理想,因其燃料几乎是取之不尽的而且其产物无污染问题.为了达到可控核聚变所需的高温高压,50年代设想“行星式”装置与磁镜装置,60年代建成托克马克,70年代80年代又有激光核聚变与冷核聚变此起彼伏。在这些技术中,以托克马克的进展最快(见表1),欧洲联合环流器自1991年9月起的聚变实验已实现2秒的约束时
The need for energy and environmental concerns have led to the search for new ways for mankind. Fusion of nuclear energy among many new energies is ideal because of its almost inexhaustible fuel and its pollution-free products.In order to achieve controlled fusion The high temperature and high pressure required in the 1950s envisioned “planetary” devices and magnetic mirror devices. The so-called Tokemark was built in the 1960s and another laser fusion and cold fusion took place in the 1970s. Among these techniques, the fastest progress has been made in Tokemark (see Table 1) and the fusion experiment of Euroccluster since September 1991 has achieved a 2-second constraint
