There is difficult of joining coupling box of driving system of section mill ,so a mill jigger equipment was developed by Jiaozuo Iron and Steel Co which has simple structure,and can shorten the shafts changing time from 6 hours to 4 hour

由于型材轧机主传动系统中轧机与齿轮箱、轧机与轧机间梅花接轴联接困难，焦作钢铁公司研制出一种轧机盘车装置，该装置结构简单，可使更换工装时间从 6h缩短为 4

In order to achieve the setting up angle should be monitored and debugged, a new approach is brought up. With the CCD receiving the focusing spot of parabolic mirror, while rotating the parabolic mirror, collecting the focusing spot location information, the eccentric angle between the optical axis and the structural central axis could be found. System principle and design have been studied.The experimental results meet the need to test and monitor to the setting up angle of the discal parabolic mirror.

为了实现对抛物面反射镜的装配角度进行监控和调试，提出了一种通过CCD接收回转抛物面镜的聚焦光斑，同时旋转抛物面镜，采集光斑重心位置信息，从而计算出光轴与结构中心轴之间的偏心角的实现方案，并从方案原理和设计上对其进行研究和实验，实验结果证明该系统能应用于对盘状抛物面反射镜装配角度的测试和监控。

Revolved around the following questions, the part analysis systematically which kinds of ritual is prevailing in the different stages of Shang and Zhou: the standard of classification of rituals recorded by oracle bone inscription, the kinds of rituals in oracle bone inscription, textual and bronze inscription, the degree of factualness recorded in lishu of Eastern Zhou.

围绕殷墟卜辞中祭祖仪式分类的标准，卜辞、文献、金文中所见商代后期、西周春秋时代祭祖仪式的种类，东周礼书中常祀的历史真实性等问题展开论述，并对殷代（本文中"商代"与"殷代"代表两个不同的历史阶段，后者指从盘庚迁殷到武王克商之间的历史时期）前期、西周春秋时代等历史阶段贵族经常举行何种祭祖仪式作了系统分析。
