研究了电阻性介质中有限长全等体链沿着直线的运动。本研究的主要目的是调查这样的系统的基本属性，特别是，他们的能力，从一个静止的状态，并保持在恒定的平均速度在介质中的运动具有不同的阻力特性和控制策略的影响的运动。通过改变链体之间的距离来激励和控制运动。对于给定的摩擦定律，建立了系统能够从静止运动的充分必要条件。
The motion of a finite chain of identical bodies along a straight line in a resistive medium is studied. The major aim of this study is to investigate the fundamental properties of such systems, in particular, their ability to move from a state of rest and sustain the motion at constant average velocity in media with different resistance properties and the influence of the control strategy on the motion. The motion is excited and controlled by changing the distances between the bodies of the chain. For a given friction law, the necessary and sufficient conditions for the system to be able to move from rest are established.
