　简述了超高速磨削的概况。对自行研制的超高速实验磨床的主轴径向间隙与轴向间隙、主轴加工精度和表面粗糙度以及轴承供油系统进行了合理的调整。适当加大轴向间隙和径向间隙,且后轴承径向间隙略大于前轴承径向间隙,可保证主轴在超高速运转时正常工作,减少振动,防止抱轴。采用工艺轴刮研轴承获得均匀的径向间隙。超高速磨床主轴与动静压轴承之间相对滑动速度较高,选用粘度较小的L-FD2主轴油,可使主轴得到良好的润滑,减少发热量。提高主轴的加工精度和降低表面粗糙度,可提高主轴的旋转精度和减少主轴的磨损。试验证明合理的选择主轴径向间隙和轴向间隙是改装超高速磨床的关键技术之一。

The 7th International Conference on Computer-Aided Industrial Design and Conceptual Design (CAID&CD’2006)

作者： YAN Tai-shan 1 2 CUI Du-wu 1 (1. Institute of automation science Xi’an university of technology Xi’an Shaanxi 710048) (2.Department of Computer science Hunan Institute of technology Yueyang Hunan 414000)

The technique of automated visual inspection is a new development in computer inspection. It has many advantages such as no touching with inspected objects, high speed, high efficiency and good flexibility, etc.. So it has extensive applied foreground in the modern automatic inspection of product quality. This paper introduces the general structure of the computer vision inspection system, expounds the realization method of an on-line crack inspection system of glass bottles, which combines with neural network principle. The system’s ability to learn itself and adapt itself is very powerful, it has realized a quick and exact inspection of the on-line glass bottles’ crack successfully.

作者： Chenqian Jiang Jinian Bian Kang Zhao Kun Tong Department of Computer science and technology Tsinghua university

Resent years, IP reuse has become a key factor for SoC design productivity improvement. A standard component library with a certain scale is crucial to the whole process of IP reuse. In this paper, we present a complete design and implementation of a component library which supports the system level design automation. The main contribution of this paper contains two aspects: first, it establishes the data structure for the reusable component, and the data structure contains the data needed in system level design;second, it describes the design and realization of the tool to manage the component library.

急性淋巴细胞白血病(ALL)图像数据集中有着类间形态学相似、数据不平衡的问题。文中设计了一种包含多尺度空间注意力和通道注意力的卷积模块,可以更好地提取不同类别图像的细颗粒特征信息,用于分类器的预测分类。使用加权交叉熵损失函数惩罚样本数量多的类,让模型学习不会偏向多数类。在此基础上引入累积学习策略,随着训练进程动态地调整正常损失函数和加权损失函数的比重,避免了加权损失函数对表征学习的损害,保持了对分类器的促进效果。最终在开源白血病细胞图像数据集C-NMC验证该设计方法的可行性,实验结果表明,测试集F1分数达到96.2%,对白血病细胞图像有着良好的识别效果。
