Landing strings equipment are heavy-duty thick wall drill pipes, which are used for oil and gas well drilling purposes in offshore areas. These are also used for landing heavy equipment on the seabed and landing heavy casing strings in wells. In subsea wells, landing strings allow well intervention or completion activities to be performed safely from floating vessels by interfacing with the subsea wellhead on the seabed. Landing strings are thick-walled steel tubes that are used to connect offshore drilling rig surface equipment with the bottom hole assembly.

Trolleys are used in industrial, airports, hospitality, and other applications to move goods from one place to another. Vendors manufacture different types of trolleys depending on the needs of the target industry.

无框力矩电机是一种无框架式永磁电机（永磁电机属于一种直流伺服电机），只有转子、定子两个部件（没有轴、轴承、外壳或端盖等）。转子是内部部件，由带永磁体的旋转钢圆环组件构成，直接安装在机器轴上。定子是外部部件，齿轮外部环绕钢片和铜绕组，以产生紧密攀附在机器壳体内的电磁力。无框力矩电机让机器结构设计不再受制于电机壳体的束缚，利用机器的自身轴承支撑转子，将电机无缝内置于机器设计中。

托卡马克是当前最具商业化潜力的核聚变技术路径之一，也是各个大国开展聚变实验时重点聚焦的技术路径。随着高温超导技术的突破，民营资本大量涌入可控核聚变赛道，“洪荒 70”（能量奇点）、“SUNIST-2”(星环聚能)等托卡马克装置运行进程提速。在这篇报告中，我们主要梳理了托卡马克的运行原理及构成、其长达 50 年的发展史、目前面临的技术上的挑战，以及各国科学界对于托卡马克未来发展的展望。
