功的大小

结果表明，TATB与氟聚合物间界面张力及粘附功的大小主要由它们的极性匹配情况决定，极性越匹配，则界面张力越小，粘附功越大，粘接越牢固。

The results show the TATB has small interfacial tension and big adhesive work to fluoropolymer when their polarity is matching very well .

功的大小等于力和距离的乘积。

The amount of work is equalto the product of the force by the distance .

指出，用冲击力-位移曲线测出的裂纹稳定扩展功的大小，反映了材料的韧性好坏，弥补了用冲击总功作评估的不足。

It shows that the crack energy of stable propagation measured by the impact-displacement curve reflects the quality of the toughness of the material and remedies the disadvantage evaluated by the total impact work .

而影响土壤抗剪强度的因素很多，例如植物根系的符合作用、击实功的大小以及长期人为扰动对土壤力学性质的影响。

The effect of soil shear strength of many factors , such as plant roots , with effect of compaction as well as the size of the long-term effect of artificial disturbance on soil properties .

只要操作者掌握冲击能Ud和断裂功Ak的大小，就能比较可靠地进行井下解卡并打捞或往井下投放其它工具等作业。

The operator can accomplish the operations of retrieving the stuck tool or running some given tool in the hole reliably , so long as he has a good grasp of the impact energy U_d and the shearing work A_k .
