查询词典 muff joint

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。

Methods : The defect of bone, skin and vessel in the bone and joint of limbs was treated by microsurgical method and the bone and joint injury was repaired by the external fixation supporter of odjustment cross joint with three Kirschner wires, keeping the free motion of every joint.

在四肢关节部位有骨缺损或骨折伴有血管损伤、皮肤缺损等病例，应用带血管的骨关节块移植、游离血管移植或各种皮瓣移植等显微外科方法修复后的同时，用三针可调外固定器跨关节外固定治疗骨关节损伤，保持各关节的自由活动。

"Go back to your work, Becky," Miss Amelia had said; but she had stopped to pick up reverently first a muff and then a coat, and while she stood looking at them adoringly, she heard Miss Minchin upon the threshold, and, being smitten with terror at the thought of being accused of taking liberties, she rashly darted under the table, which hid her by its tablecloth.

"干你的活儿去，贝基，"虽然阿米莉亚小姐已经斥责过她了，但她还是留在了那里，先是无比敬仰地拣起了一只皮手套，随后是一件外套，就在她站在那儿羡慕地欣赏时，听见铭钦女士已经到门口了，这才想起自己如此随意的举动务必会遭到责斥，禁不住开始感到害怕，情急之下她冒险钻到了桌子下面，桌布把她给遮蔽了。
