Our digital communication network has been engineered so that copies flow with as little friction as possible.
我们的数字通信网络被打造成让拷贝流尽量畅通无阻。
"There is just too much friction in getting capital to flow," he says.
他说：“获得这些用于周转的资金真是太难了！”
Low friction-the coefficient of friction between the chip and tool should be low. This would allow for lower wear rates and better chip flow.
低摩擦系数—切屑与刀具间的摩擦系数应当较低。这会使磨损率较小及切屑流动更好。
