Analyzed the structure characteristics of the perfume cover outer shell plastics piece, described the piece's structure and work principle which model a craft and inject a mold, its principle :adopt and certainly be apart from bolt and spring coil and carry on two cents type, use inclined lead a side outside the pillar and take out heart, type the heart crest spare parts, while entering and anticipating adoption incubate the type sprinkle into anticipate a form, while opening a mold, with the ball head pull and anticipate a pole sprinkle and note system and anticipate, then make use of and take out and push plank and release a plastics piece inside a heart,use spring coil and reset first while matching a mold, then carry on willing model a beginning next time.

摘要分析了香水盖外壳塑件的结构特点，叙述了该塑件成型工艺、注射模的结构和工作原理，其原理是：采用定距螺钉和弹簧进行二次分型，用斜导柱外侧抽芯，型芯顶出零件，进料时采用潜伏式浇口进料形式，当开模的时候，用球头拉料杆把浇注系统凝料顶出，然后利用型芯内抽推板推出塑件，合模时用弹簧先复位，然后进行下一次成型开始。

These three internal fixations of femoral peritrochanteric fracture were differ. For example, Gamma nail is less harmful, better clinical treatment, shorter in shape and stronger in anti-hip inversion. DHS, DCS have a better treatment and are stronger in anti-hip inversion but more harmful and excessive bleeding, and HCS, which is named Minimally Invasive Surgery, is the least harmful, less bleeding, suitable for old patients and the patients of tolerance of poor operation, but poor in anti-hip inversion.

3种不同方法内固定治疗转子间骨折具有各自的特点，Gamma钉具有手术损伤小及良好的临床疗效力臂短对抗髋内翻的能力强；滑动加压鹅头钉具有良好的临床疗效及相对坚强的抗内翻能力，但手术损伤相对较大，失血量较大；空心加压螺钉固定的手术损伤最小，属于微创手术方法，可经皮完成，手术出血少，适用于高龄及手术耐受性差的患者，但抗髋内翻的能力最差。

Atechnique of low-profile fixation using obliquely oriented screws from the radial head into the shaft has been developed to avoid distal dissection of the soft tissues and placement of hardware in an already-constrained area adjacent to the annular ligament and lateral ligamentous structures.
