宽度循环 meaning in Chinese

repeat in the width

To estimate the influence of the flatness ratio on hydrodynamic performance , a group of torque converters with different widths were investigated by cfd simulation to improve the power diversity and reduce the mass based on the variable - width circulatory circle torque converter design method
摘要在变宽度循环圆设计方法的基础上，为提高液力传动系统功率密度，减轻质量，对几组不同宽度比循环圆的变矩器进行了cfd （计算流体动力学）数值模拟，借以评估对其整体传动性能的影响。
