work of cohesion meaning in Chinese

内聚功

The work of cohesion increased with the enhancement of wettability , but the bending strength of the welding specimens did not . when wc or mo was added the mode was adhesive rapture ( ii ) because of the difference between the thermal expansion coefficient of wc , mo and ni . the bending strength was high when iv rapture was occurred
研究发现粘附功随润湿性的改善而提高，但是焊接试样的抗弯强度并没有呈现明显的这种趋势；由于wc和mo与金属ni热膨胀系数相差较大，焊接试样断裂方式为内聚型断裂(型断裂) ，抗弯强度较低；以型方式断裂的体系具有较高的抗弯强度。
