针对机场延误预测过程中难以提取延误传播时空特征、预测结果受天气扰动大的问题,提出了基于气象因素的时空图卷积网络(meteorology-based spatio-temporal graph convolutional networks,MSTGCN)机场延误预测模型.该模型使用图卷积神经网络(graph convolutional neural network,GCNN)与门控卷积神经网络(ga-ted convolutional neural network,Gated CNN)挖掘机场延误的时空特征,同时加入气象特征提取模块对机场延误时间进行预测.实验结果表明,该模型在中短时预测上的表现均优于其他对比模型;相较于不考虑气象因素的模型,MSTGCN对未来1 h、4 h和12 h预测的平均绝对误差分别降低了 7.03％,7.93％,11.54％,对预测结果起到了极大的修正作用.

Abstract ：

With the emergence of various intelligent applications,machine learning technologies face lots of challenges including large-scale models,application oriented real-time dataset and limited capa-bilities of nodes in practice.Therefore,distributed machine learning(DML)and semi-supervised learning methods which help solve these problems have been addressed in both academia and indus-try.In this paper,the semi-supervised learning method and the data parallelism DML framework are combined.The pseudo-label based local loss function for each distributed node is studied,and the stochastic gradient descent(SGD)based distributed parameter update principle is derived.A demo that implements the pseudo-label based semi-supervised learning in the DML framework is conduc-ted,and the CIFAR-10 dataset for target classification is used to evaluate the performance.Experi-mental results confirm the convergence and the accuracy of the model using the pseudo-label based semi-supervised learning in the DML framework.Given the proportion of the pseudo-label dataset is 20％,the accuracy of the model is over 90％when the value of local parameter update steps be-tween two global aggregations is less than 5.Besides,fixing the global aggregations interval to 3,the model converges with acceptable performance degradation when the proportion of the pseudo-label dataset varies from 20％to 80％.

Abstract ：

T-jointtitanium alloy structures are commonly used in aircraft manufacturing, and their laser welding process is relatively ma-ture, but due to the strict requirements of the airplane production, the angular deformation caused by uneven heat input across the sheet is still not negligible, so active control needs to be imposed. In this paper, an active deformation control method based on programmable multi-point flexible support is proposed and validated. In response to the problem that the traditional rigid clamping and pre-stressing are not adap-ted to the T-structure thin sheet, this study has designed a multi-point flexible support with microcontroller and electric actuators, which can monitor the stress state of the current support position in real time during the welding process and make dynamic adjustment,so that the weld deformation could be effectively reduced in this way.

Abstract ：

The current researches on microorganisms in anammox system were mainly focused on anaerobic ammonium oxidation bacteria. The microbial community structure and the key kinetic parameters of anaerobic ammonium oxidation bacteria (AnAOB), ammonia oxidizing bacteria (AOB), nitrite oxidizing bacteria (NOB) and denitrifying bacteria (DNB) in anammox filter were measured and analyzed in this study. Moreover, the effects of DO concentration in the range of 0.2~1.5mg/L on the activity of AnAOB, AOB and NOB were investigated. The results showed that the anammox filter of long-term stable operation was still a mixed system with multiple bacterial groups, in which anammox bacteria was the main function bacteria. The activity of AnAOB with 5.3mgN/(gVSS•h) was the highest among the functional bacteria in the filter; whereas DNB and AOB had a certain activity. When DO concentration increased from 0.2mg/L to 1.5mg/L, the activity of AnAOB almost kept stable; whereas, the specific ammonia oxidation rate of AOB increased from 0.76mgN/(gVSS•h) to 1.08mgN/(gVSS•h). The obtained oxygen half saturation constant (KO2, AOB) of AOB was (0.106 ± 0.010) mg/L, which indica ted that AOB has high affinity for oxygen. During the entire experiment, the activity of NOB was not detected. Therefore, in the anammox system, the main functional bacteria coexisted and competed each other for substrates. © 2021, Editorial Board of China Environmental Science. All right reserved.

模糊限制语在日常言语交际中的运用十分普遍,恰当地使用模糊限制语能够准确表达言语内容以及缓和人际关系.Spencer-oatey打破传统的人际语用学的面子论为核心的传统,提出了人际和谐管理模式,一定程度上促进了模糊限制语在语用学领域研究的深入.该研究以Spencer-oatey的人际和谐管理模式为理论依据,采用Prince对模糊限制语的分类模型,自建小型语料库,探索研究了TED演讲中模糊限制语使用的频率和分布特点,并举例探讨了模糊限制语在TED演讲中的语用功能.结果发现,在该语料中使用最多的模糊限制语的类别是范围变动型模糊限制语.各类模糊限制语如直接缓和语,间接缓和语和程度变动语分别起到维护说话者素质面子、社交身份面子、维护听众的平等交往权的作用.
