首先，采用ResNet18作为主干网络提取特征，引入分组卷积减少ResNet18的参数量；利用倒残差结构增加网络深度，优化了图像特征提取效果。
其次，将CBAM（Convolutional Block Attention Module）通道注意力模块中的共享全连接层替换为1×3的卷积模块，有效减少了通道信息的丢失；在CBAM空间注意力模块中添加多尺度卷积模块获得了不同尺度的空间特征信息。
最后，将多尺度空间特征融合的CBAM模块（Multi-Scale CBAM，MSCBAM）添加到轻量的ResNet模型中，有效增加了网络模型的特征表达能力，另外在引入MSCBAM的网络模型输出层增加一层全连接层，以此增加模型在输出时的非线性表示。
该模型在FER2013和CK+数据集上的实验结果表明，本文提出的模型参数量相比ResNet18下降82.58%，并且有较好的识别准确率。

Firstly， ResNet18 is used as the backbone network to extract features， and group convolution is introduced to reduce the parameters quantity of ResNet18. The inverted residual structure is used to increase the network depth and optimized the effect of image feature extraction.Secondly，the shared fully connected layer in the channel attention module of CBAM is replaced with a 1×3 convolution module，which effectively reduces the loss of channel information.The multi-scale convolution module is added to the CBAM spatial attention module to obtain spatial feature 文章编号：1007-2780（2023）11-1503-08收稿日期：2023-02-08；修订日期：2023-03-18.基金项目：国家自然科学基金（No.61971272，No.61601271）；陕西科技大学博士启动经费（No.2019BJ-27）Supported by National Natural Science Foundation of China （No.61971272，No.61601271）；DoctoralStart-up Fund of Shaanxi University of Science and Technology （No.2019BJ-27）*通信联系人，E-mail：2427135900@第 38 卷液晶与显示information at different scales. Finally， multi-scale CBAM module （MSCBAM） is added to the lightweight ResNet model， which effectively increases the feature expression ability of the network model. In addition，a fully connected layer is added to the output layer of the network model introduced into MSCBAM， so as to increase the nonlinear representation of the model at the output. The experimental results of the model on FER2013dataset and CK+ dataset show that the parameters quantity of the model proposed in this paper is reduced by 82.58% compared with ResNet18，and the recognition accuracy is better.Key words： lightweight resnet network；multi-scale spatial feature fusion；facial expression recognition；attention mechanism1 引言面部表情是人类交流和传达情感的普遍信号之一，能够直观表达人类对外界事物的情绪反馈。

NX75 同步建模Synchronous Modeling目的目的NX 提供你用于修改模型的工具, 不管是否有参数存在。
同步建模命令用于修改一模型, 不不管它的由来、相关性或特征历史。
基于本课程完成, 你将能够o:•使用历史和非历史模式。
•作用同步建模约束。
•移动和代替一个模型的面。
•使用抽壳体, 代替面, 抽壳面和改变壳厚度。
•在独立于历史模式冲利用横截面编辑功能。
•利用拖拉面和移动面修改一个模型的面。
•利用线性, 角度和半径尺寸去修改模型的尺寸。
•利用考贝面, 偏置区和粘贴面去改模型。
综述综述同步建模命令用于修改一模型, 不不管它的由来、相关性或特征历史。
模型可以是从其它CAD 系统读入，非相关的, 设有特征的, 或一本地包括特征的NX 模型。
通过直接用任一模型工作, NX 消除浪费在重构或转换几何体的时间。
同步建模主要适用于在由解析面如平面,柱面,锥面,球面和环面组成的模型上。
这不必要意指”简单”部件,因为有几千面的模型是这这些类型面组成的。
用同步建模, 设计师使用参数化特征而没有特征历史的限制。
综述下例仅利用了三个同步建模命令。
它们是在一非参数化模型上做的。
但同样可以由参数化特征来完成。
1.原来的非参模型2.用于移动前面与后面增宽皮带轮的拖拉面3.用于移动皮带沟槽的移动面4.用于添加一附加皮带沟槽的考贝面。
基于历史与独立于历史的建模模式当工作在建模应用中时, 你可以是在下列两种模式之一中:•基于历史的模式•独立于历史的模式基于历史的模式在基于历史的模式中, 你利用一显示在Part Navigator中有序的特征建立与编辑模型。
这是传统的基于历史的特征建模模式和在NX中主要的设计模式。
对于高度工程部件这种模式是有用的。
对利用基于设计意图构入草图，特征中预定义参数修改的设计部件, 和特征序用于模拟部件也是有用的。
独立于历史的模式在独立于历史的模式中, 你建立与编辑模型基于它的当前状态, 没有一有序的特征。
