Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.

程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。

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。
