The arm modules actively support the wearer's arms, taking the load, so it feels only a tenth of its real weight.
手臂模块积极支持佩戴者的手臂，走的负载，所以感觉其实际重量只有十分之一。

The shearer's ranging arm is a multi-body system and the load characteristic is very complicated, so it brings many difficulties to research dynamic property with traditional computational method.
采煤机截割部是一个复杂的多体系统，其负载特性非常复杂，采用传统的计算方法研究其动态特性非常困难。

Alternatively, the load reacting unit (9) may be connected between the arm (4) and the lower portion (3) of the shock absorber strut to act as a pitch trimmer.
