the author of this paper holds that the conflict between law and morality at the turning moment of the present society will bring serious social problems.
in hydraulic transmission system, turning moment and rotational speeds of pump impellers and turbines have to be kept steady in order for the normal operation of the system.
在液力传动系统中,泵轮和涡轮的转矩及转速应保持稳定才能使系统正常运行。
but since independently rotating wheels have no turning moment resulting from longitudinal creepage, independently rotating wheels lack guiding ability and can but basically depend on flange to guide.
