The risk of total systems failure was equivalent in the X-29 to the risk of mechanical failure in a conventional system.

失败的总系统的风险是在传统系统中的X - 29相当于机械故障的风险。

Not disturbing it is the quantum-mechanical equivalent of not really looking.

ECONOMIST: Physics and philosophy

To fully emulate the human leg will involve motors, the mechanical equivalent of muscles, and electrical sensors that gather the same input as the human nervous system.
