The drum,screw, screen changer and die head are made of high quality alloyed steel (38CrMOAIA) with high hardness, strong corrosion resistance and long operating life after nitrogen treatment.

螺杆、料筒、换网器、模头均选用优质合金钢（38CrMoAIA），经氮化处理，硬度高、防腐能力强、使用寿命长；模头为衣架式支管递减型，流道利于熔料流动、无滞留现象，片材厚度均匀；压光琨内采用螺旋往复式水槽，水循环冷却，效果极佳；模头、换网器、料筒温度分段控制，整机传动同步运行。

This paper establishes cubic spline function, analyzes subsection curve function and curve slope and curvature, at last decides to place the curve especial points which can be obtain easement curve length and other line parameters, such as the ZH point (end of line and beginning of transition curve), the HY point (end of transition curve and beginning of circular curve), the QZ point, the YH point (end of circular curve and beginning of transition curve), the HZ point (end of transition curve and beginning of line).

针对公路平面线形的8种组合类型，其线形元素特征则由最基本的直线、圆曲线、缓和曲线组成的特点，解析三次样条函数模型，得分段曲线函数、曲线斜率、曲率，从而确定曲线特征点（直缓ZH点、缓圆HY点、曲中QZ点、圆缓YH点、缓直HZ点）位置，进而得到曲线缓和曲线长度及其他线形参数。

This heating is done in steps with rest periods of about 30 min between each temperature increment, this stepwise heating permits specific amylases and proteinases to function before they are heat inactivated.
