试验结果表明：减小浆网速比， 增强了纤维定向作用，裂缝纵向分布增加，导致纸张中纵横向断裂韧性差异增加。
The results indicate that the difference of fracture toughness between MD and CD increases with a decrease in jet_wire speed ratio, and the main reason is stronger fibre orientation.
同时采用陀螺定向系统有效地抑制了导线横向误差积累。
At the same time, the accumulated error of traverse measurement is effectively controlled by use of a gyro orientation system.
模拟结果表明，在L型定向风帽流化床中，颗粒存在顺时针方向的循环流动，因此床料的横向混合特性较好。
The simulation result indicates that there is clockwise particles circulation in fluidized beds with L-type wind caps.
