“卓越培养计划”背景下设施专业CAD课程改革

指出了CAD是青岛农业大学设施专业一门重要的基础核心课程,但目前教学中存在着理论课与实践课分开、理论教学单调、与设施专业结合较少等问题。针对上述问题,基于教育部系列卓越教育培养计划及青岛农业大学2020版本科培养修订指导方案提出了融合混合式教学与案例教学的教学改革建议:根据课程重点及教学要求,重新编写课程大纲;进行线下与线上的混合式教学,其中线下教学将理论课与实践课合并,线上结合“翻转课堂”形式授课;采用案例教学法,带领学生完整设计温室设施并绘制CAD图纸;期末考核形式改革。经过以上改革,学生对CAD软件的操作熟练度及技巧明显提高,且增强了温室设施的设计及绘图能力,为日后从事相关工作奠定了基础。

PAYING ATTENTION TO USE SIMPLEX METHOD FOR OPTIMAL MULTIPARAMETER IN THE DESIGN OF CONTROL SYSTEM

In the design of control system using simplex method for optimal multi-parameter,if the difference in number between the greatest and the smallestparameters is very great,the optimization process converges very slowly.Evenoptimal parameters can't be found at all.This paper studies the problem,analyses its cause and poses a resolution means.A testing example shows thatthis means can solve the above problem well.     

The Storage of Tree Data Structure by Gradation and Classification and Application in CAD for Engineering Structure

The traditional storage of tree data structure is according to the relation of the elements' frant-and-back. Since it is difficult to define the frant-and-back relation of graphics units in CAD for Engineering structure, the application of the tree structure becomes inconvenient. The authors change the storing method for the tree structure into gradation and classification. And a graded equivalence relation of graphics units is brought forward, which grade the graphics units with the equivalence relation. By using this storing method, we can easily accomplish some operations, such as picking up the subtree with a certain character, deleting a node, insert a graded and classified node, etc. The example provided indicates that the storage by gradation and classification can speed up searching and process the data of the subtree by gradation and classification expediently. This kind of storing method for the tree structure is applicable for data which contain the graded equivalence relation.
