针对深度神经网络用于滚动轴承故障诊断时,网络隐含层层数、各隐含层节点数、稀疏系数以及输入数据置零比例等超参数会直接影响网络诊断性能的问题,提出了一种优化改进堆叠降噪自编码器(SDAE)的滚动轴承故障智能诊断方法。使用学生心理优化算法(SPBO)对降噪自编码器(DAE)网络的超参数进行自适应选取来确定SDAE网络的最优结构和参数,据此提取具有更强表征力的故障状态特征表示,输入到soft-max分类器实现滚动轴承运行工况的精确诊断。使用3个开源数据集对所提网络的性能进行验证,实验结果表明,基于SPBO-SDAE网络的诊断方法在特征有效提取、诊断速度以及故障诊断准确率方面均优于支持向量机(SVM)、反向传播(BP)神经网络、径向基(RBF)神经网络、SDAE网络、SPBO优化后的深度置信网络(DBN)、遗传算法(GA)优化后的SDAE网络以及粒子群算法(PSO)优化后的SDAE网络。

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

The underground water testing over the years has found that the total dissolved solids, total hardness, chloride, nitrate(calculated in N) and many other factors in the underground water in Shijiazhuang exceed the limits specified in Sanitary Standard for Drinking Water GB 5749-2006 and are distributed in a point source pattern. Starting by introducing the hydrological and geologic characteristics of Shijiazhuang, this paper analyzes the chemical properties and pollution status of the underground water in the city and the effect of factors that exceed the standard on the human body. Based on the analysis, it further discusses the causes for pollution and cases of pollution treatment that absorbed tremendous manpower and resources in the past and thus resulted in huge economic losses to the state. The paper concludes that it is extremely important to make a serious commitment to the pollution control. Judging from the hydrological conditions, the southeast part shows stronger anti-pollution performance than the northwest under the natural state.

Background The effect of impaired glucose tolerance （IGT） on cardiac function during the chronic prediabetes state is complicated and plays an important role in clinical outcome. However, the molecular mechanisms are not fully understood. This study was designed to observe cardiac dysfunction in prediabetic rats with IGT and to determine whether glucose metabolic abnormalities, inflammation and apoptosis are linked to *** The IGT rat models were induced by streptozocin, and the heart functions were assessed by echocardiography. Myocardial glucose metabolism was analyzed by glycogen periodic acid-Schiff staining, and the pro-apoptotic effect of IGT was evaluated by TUNEL staining. Additionally, caspase-3 activation, macrophage migration inhibitory factor （MIF） and G-protein coupled receptor kinase 2 （GRK2） were detected by Western blotting in cardiac tissue *** Area-under-the-curve of blood glucose in rats injected with streptozotocin was higher than that in controls, increased by 16.28%, 38.60% and 38.61% at 2, 4 and 6 weeks respectively （F=15.370, P=0.003）. Abnormal cardiac functions and apoptotic cardiomyocytes were observed in the IGT rats, the ejection fraction （EF） being （68.594-6.62）% in IGT rats vs. （81.07±4.59）% in controls （t=4.020, P=0.002）. There was more glucose which was converted to glycogen in the myocardial tissues of IGT rats, especially in cardiac perivascular tissues. Compared to controls, the cleaved caspase-3, MIF and GRK2 were expressed at higher levels in the myocardial tissues of IGT *** IGT in the prediabetes period resulted in cardiac dysfunction linked to abnormal glycogen storage and apoptosis. Additionally, MIF and GRK2 may be involved in the pathogenesis of cardiac dysfunction in prediabetes and their regulation may contribute to the design of novel diagnostic and therapeutic strategies for those who have potential risks for diabetic cardiovascular complications.
