实际

In 1999, we began to sort out the research results and carry out the second-round experiment. The original aim of this research project is to resolve the problems in actual situation and sets up a bridge between problems and experience, so that educational research can play a particular role in the teaching practice. It is a dynamic process of practice—problem settling---reparctice---problem resettling.

本课题的研究本身是一项行动研究，是由实际工作人员和研究者合作进行的，将实际工作者的实践活动与研究者的学术性探究活动相互联系的一种研究活动，具体而言是在上海市实验学校领导的支持下，由学校老师共同参与共同进行的一项研究。1997年度和1998年度学校连续两年将小学和初中阶段进行的综合模块课程研究立为学校的科研项目，1999年度课题进入研究成果的整理阶段并开始进行第二轮实验。

The author particularizes its four manifestations.firstly,only accepting that practice tests theory,and not accepting that theory tests practice;secondly,simply and unilaterally understanding the theory originated from practice;thirdly, simplifying and vulgarizing the theory innovation;lastly,simplifying and vulgarizing applying theory to practice.

本文认为在我国理论界和实际工作者中存在着一种片面强调实践的重要性、忽视或不能全面理解理论对实践的能动作用的惟实践主义倾向，从理论与实践关系复杂性的角度并列举了其四种表现：(1)只承认实践检验理论，不承认理论检验实践；(2)对理论来源于实践作简单片面的理解；(3)把理论创新简单化、庸俗化；(4)把理论联系实际简单化、庸俗化。

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。
