The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

Penguin dropping soil enriched fluorine, whilst deadly fluorine concentration was also detected in penguin bone. However, radiographs of Adelie penguin bones show no symptoms of fluorosis .

企鹅粪土中富集元素 F ，在企鹅骨骼中也发现 F 元素的富集，但经过 X 光鉴别并未发现企鹅患有氟骨病。

By using AAS and XRF, the contents of Cr, Pb, Mn, As, Se, Hg, Cd, Zn in raw coal, bottom ash and fly ashes are measured quantitatively in a 220 t/h pulverized coal boiler. Factors affecting the distribution of trace elements are investigated, including fly ash diameter, furnace temperature, oxygen content and trace elements' characters. The coefficient of Meij is also improved to more directly show element enrichment in combustion products. Elements may be classified into three groups according to volatility features of trace elements.

采用原子吸收分光光度计和X射线荧光光谱仪，定量测定了电厂煤粉炉中原煤、底渣、飞灰中Cr、Pb、Mn、As、Se、Hg、Cd、Zn等微量元素的含量，分析了飞灰粒径、炉膛温度、炉内含氧量、微量元素自身性质对微量元素赋存、挥发特性的影响，并根据元素的挥发特性将元素进行分类，得出表征微量元素排放特性的3种数值，并与我国和欧盟垃圾焚烧微量元索排放标准相对照。
