针对在筛查新型冠状病毒感染肺炎患者时核酸检测假阴性率较高的问题,提出了一种DRPL-ViT计算机辅助诊断网络。在Vision Transformer的基础上首先引入知识蒸馏机制,使Transformer结构在小数据集上训练取得更好的拟合效果;然后,在patches的位置信息编码上,通过更适合视觉任务的相对位置编码方式,使tokens之间的依赖关系能够被更好地捕捉;为了关注到更多的局部特征,在Transformer Encoder模块中引入了传统的卷积模块提取局部特征。实验在四分类测试集上平均分类准确率达到92.11%,对新冠肺炎分类准确率达到97.85%。实验结果表明,所提出的网络对新冠肺炎及其他肺部病变分类准确率较高,有一定的临床应用价值。

In this paper, the operation strategy of thermal power units after the configuration of phase change heat storage station is put forward, and the mathematical model for calculating the peak-shaving capacity of thermal power units after the allocation of phase change heat storage stations is established. Based on the analysis of frequency requirements of electric power system, puts forward the analysis of high frequency and low frequency demand method by using the discrete Fourier transform, and the actual system all day long the proportion of high frequency components are quantitatively analyzed. Analyzes the effect of two typical 300 MW and 200 MW heating units in Northeast china on improving peak shaving capacity after installing heat storage stations. The results show that the peak shaving capacity of the two units can be increased by 21% and 14% at a given heat load level in the middle heating period. And based on the actual system data, the paper simulates and analyzes the FM strategy of energy storage participating in automatic generation control（AGC）. The results show that the flexible allocation of energy storage resources based on area regulation requirement（ARR） has a better FM effect.

采用目前常用的AA8030铝合金作为电缆导体,利用ABAQUS有限元软件对电气线路接续的压接过程进行模拟,分析压接处材料的应力分布特征。结果表明:电气接续的压接界面处,金具所受的径向应力明显高于铝合金电缆导体的径向力(高出5～25 MPa),更易发生蠕变变形。另外,通过短时蠕变试验建立材料的蠕变本构模型,利用ABAQUS有限元软件对该过程进行模拟,得到了与试验数据相吻合的蠕变曲线,并可推算出该材料在不同应力下的长期蠕变性能,为抗蠕变材料的定量评定提供了一种准确快捷的方法。
