Abstract］ Objective In order to observe the curative effects that black jade dipsacus cream cure bone fracture. Methods 568 cases of fracture patients that including conservative treatment and surgical treatment were divided stochastically into the treatment group and the control group with soliciting the informed consent. The treament group used the black jade dipsacus cream was spread extermally on the skin,the control group did not apply drags.We observed two groups of patients in local pains,swelling, the tenderness and the joint activity improvement situation and carried on the comparative analysis to two groups of curative effects.

目的 观察黑玉续断接骨膏治疗骨折的疗效方法将收治的568例骨折保守治疗及手术治疗后的患者，在征得知情同意后，随机分治疗组和对照组，治疗组采用院内制剂黑玉续断接骨膏外敷，对照组不用药，观察两组患者局部疼痛、肿胀、压痛及关节活动的改善情况并对两组疗效进行比较分析。

Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.

经摩擦搅拌制程改质后，硬度提升，晶出相细化且均匀分布，降低脆性龟裂的现象发生，有助於改善A384铝合金的磨耗性质，其中，亦发现在冲蚀沟槽附近有残留和脆性破裂之共晶Si颗粒和nvAl3CuNiw晶出相，推测此两相为A384铝合金中有助提升磨耗阻抗的第二相；而τ1(Al9FeNi)晶出相则容易受到冲蚀颗粒的切削而被冲蚀颗粒移除，增加材料的重量损失，推测τ1(Al9FeNi)晶出相为A384铝合金中较不耐磨耗的晶出相。
