应我司邀请，3月26日下午，宁波大学包经俊副教授在砺志楼105作了题为《Constructions of column-orthogonal strong orthogonal arrays》的报告。相关师生聆听了此次报告，报告由曹炜老师主持。

报告中，包经俊副教授主要介绍Strong orthogonal arrays have better space-filling properties than ordinary orthogonal arrays for computer experiments. Strong orthogonal arrays of strength two plus, two star and three minus can improve the space-filling properties in low dimensions and column orthogonality plays a vital role in computer experiments. In this talk, I will introduce some constructions of strong orthogonal arrays and column-orthogonal strong orthogonal arrays of strength two plus, two star, three minus and t by using difference matrices, generator matrices of linear codes and matchings of bipartite graphs.报告结束后，在座的师生就相关研究问题进行了探讨和交流。
