stand-alone capability meaning in Chinese

独立能力

Conventional dc electric propulsion system always takes up dominant station in submarine propulsion . due to dc motor inherent limitation that machine commutation and brush results in stand - alone capability ' s limit low reliability , big noises , people manage to explore more quiet , high efficient and reliability , big stand - alone capability propulsion motor
传统的直流电力推进系统一直在潜艇推进中占据主导地位，但由于直流电机本身固有的缺陷即有机械换向器和电刷从而导致单机容量有限和可靠性不高、噪音大，迫使人们探索更加安静并且高效可靠、单机容量大的推进电机。
These years along with the development of power - electronics technique and micro - control technique , permanent magnetic brushless dc motor is characterized by small volume , light weight , high efficiency , low noises , big stand - alone capability and reliability appeared and matured . so it is hopeful to become new generation submarine propulsion motor
近年来随着电力电子技术和微控制技术的迅猛发展而成熟起来的永磁无刷直流电机具有体积小、重量轻、高效低噪、单机容量大且可靠性高的特点，从而极有希望成为新一代潜艇推进电机。
