Especially, it pointed out that the design of modern steel-making electric arc furnace short net should base on three-phase balance, delta connection should be implemented inside the transformer, the section of conductor should be selected according to the density of economy electric current and the number of connected points of short net should be reduced.

围绕现代电弧炉供电及工艺方面的改进，提出短网设计与改造要点，特别指出：现代炼钢电弧炉短网的设计要以三相平衡为主，变压器的二次出线三角形封口要在变压器内实施，短网导体截面要按经济电流密度选取，以及尽量减少短网导体联接处。

It is considered that link wear speed on seal surface is proportional to the contacting pressure. The impacting of valve disk on valve seat is the important reason of abrasive wear, and the relative motion of disk is a main reason for errosion wear of pump valve. The cycles per minute is an important factor to influence the valve motion and the impact force.

结果表明，泵阀密封面联接磨损的磨损速度与密封面上的接触比压成正比，泵的冲次是影响阀盘运动规律及对阀座产生冲击的重要因素，泵阀产生磨粒磨损和疲劳磨损的主要原因是泥浆、阀盘和阀座的冲击，冲蚀磨损导致泵阀的刺蚀。

This system can realize the automation drawing respectively of thread standards and keys and pins.

Electronic map of MapInfo is introduced into the environment of object oriented by the use of Map X 4.0 module. The operations such as dynamic add, delete and edit of objects can be done real-time dynamically by operators in the environment of object oriented on the present diagram of polder region. At the same time, the spatial-data and attribute-data of irrigation district are managed separately. The spatial-data is used by the file system, whereas, the attribute-data exist in the relevent database. The figures and database are related through the only ID number in order to realize two-way inquiry, so that, the polder region river system planning data are collected automatically. Moreover, this system make the great use of GIS advantage in storing and annalising data to automatically organize files needed in river network calculation , adopt one-dimensional unsteady flow model , so as to lay out height of river levee .

把GIS技术引入水系规划，通过MapX4.0组件把MapInfo电子地图调入面向对象编程环境，使操作人员能在面向对象环境中对圩区现状图进行实时动态操作，包括对操作对象的动态添加、动态删除、编辑等；同时，将空间数据和属性数据分开进行管理，空间数据用文件系统管理，属性数据采用数据库管理，通过建立唯一ID号进行数据联接，将图形与数据库进行关联，实现属性到图形或图形到属性的双向查询，从而实现了圩区水系规划部分数据的自动采集；另外，本系统充分利用GIS存储与分析数据的功能，自动生成河网水力计算所需的文件，采用一维非恒定流模型进行河网水力计算，为确定沟道堤顶高程提供依据。

This programming includes the routing at branchings and the sequencing of goods flows at junctions.

这一个规画在分岐包括工作路线排定而且在联接包括货物的序列人流程。
