Treatment options for symptomatic lymphoceles include percutaneous drainage, percutaneous aspiration combined with the installation of a sclerosing agent (bleomycin, doxycycline, povidone iodine, alcohol, or talc),13,15,17 or surgical drainage via open or laparoscopic surgery.1214 Open surgical internal marsupialization of a lymphocele has long been the historical gold standard therapy.

有症状的淋巴管瘤处理选择包括经皮引流、经皮抽吸合并注入硬化剂（博来霉素、多西环素、聚维酮碘、酒精或滑石粉）或通过通过开放或腹腔镜手术术中引流。长期以来，开放性内部袋形缝术一直是治疗淋巴管瘤的金标准。

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.

通过对复合材料耐磨性能研究表明：复合材料的摩擦系数随载荷的增加而逐步下降，且磨损表面有明显的塑性变形；从能谱分析结果来看，复合材料表面有Fe的存在，表明PAM微纤承受了部分载荷，并阻止了基体的进一步塑性变形及粘着转移；在高速高载时，PAM1/尼龙6磨损表面处于粘流态，并在钢环表面形成了连续的转移膜，表现出较好的耐磨损性能，且在高温和强剪切力的作用下，材料基体发生了少量的α晶体向γ晶体的转移。
