FATIGUE CRACK GROWTH BEHAVIOR of 0Cr18Ni9 STAINLESS STEEL AT HIGH TEMPERATURES

研究奥氏体不锈钢0Cr18nI9在高温(550℃)下的疲劳裂纹扩展规律。测试采用标准CT(COMPACT TEnSIOn)试样,最大载荷范围为6.5 kn~14 kn,应力比为0.1(室温)和0.05(550℃)。裂纹扩展过程通过QuESTAr长焦距显微镜直接观测,同时采用COd(CrACk OPEnIng dISPlACEMEnT)规记录加载线位移。由于在高温条件下,测试终止时试样的裂纹前缘呈明显弧形,故此给出实测表面处裂纹长度有效值的修正方法。对高温疲劳裂纹扩展问题,采用应力强度因子范围Δk作为裂纹扩展驱动力参数,同时考虑高Δk和低Δk值对裂纹扩展规律的影响,得到0Cr18nI9不锈钢在550℃下的疲劳裂纹扩展规律表征模型,给出裂纹扩展率的上限结果。For austenitic stainless steel 0Cr18Ni9,fatigue crack grow law are studied at 550 ℃.The crack growth tests adopt the standard compact tension(CT) specimens.The applied maximum loads are from 6.5 kN to 14 kN and the stress ratios are 0.1(at room temperature) and 0.05(at 550 ℃).The crack growth length is directly measured by QUESTAR long focus microscope system and the load-line displacement is simultaneously recorded by using crack opening displacement(COD) gauge.Because of the good ductility of 0Cr18Ni9 at high temperatures,the crack front curves on fracture surface of the specimens are complex.In order to get an effective crack size,a modified method for crack length inspected on the surface is proposed.The stress intensity factor range ΔK is used as the driving force parameter of fatigue crack growth.Considering the high ΔK and the low ΔK effects on the fatigue crack growth law,the fatigue crack growth law is obtained for stainless steel 0Cr18Ni9 at room and high temperatures and the upper bound to the crack growth rate is given.国家自然科学基金(50605039);福建省新世纪优秀人才支持计划资助项目---

深度学习在电力负荷预测中的应用

针对电力负荷预测中存在的随机性、不确定性的问题,结合深度学习算法具有很强的自适应感知能力等特点,采用目前较为主流的深度学习方法,如长短时记忆(LSTM)网络、门循环单元(GRU)神经网络和栈式自编码器(SAE),分别研究其应用于电力负荷预测时的效果。研究发现,将历史负荷数据作为三种深度学习预测模型的输入时,三种预测模型的负荷预测精度指标评估结果各有不同。因此,为了全面评估三种预测模型的预测效果,提出将不同时间段内的相同历史负荷数据作为预测模型输入对比各模型的负荷预测精度,从中找出最佳的预测模型。仿真结果验证了三种预测模型在电力负荷预测应用中的可行性,且发现在单输入因素时LSTM模型的预测精度相对较高。因此,在后续研究中,可以考虑以LSTM预测模型作为基础预测模型,结合更多的负荷影响因素进行改进,以提高负荷预测精度

Advances in Studying the Sea-Air Dimethysulphide Exchange Process in the Southern Ocean

二甲基硫(dMS)是一种重要的海洋生源硫化物,通过海—气交换进入大气后生成生物源硫酸盐气溶胶从而对气候产生影响。海洋是大气dMS的主要源地,海洋大气中约90%的dMS来自海洋。南大洋占世界大洋面积的20%,是全球dMS重要的源之一。相较其他海域,南大洋表层海水dMS存在显著的时空变化。由于南大洋复杂的水文环境、多变的海冰情况和受多种生物活动作用的影响,完全了解这一区域dMS海—气交换过程及其控制因素变得更加复杂、困难。此外,开展dMS的冰—气交换过程及其控制因素的研究也很有意义。为了便于今后在极区开展dMS海—气交换过程的研究,深入探究极区dMS的生物地球化学过程。因此,对南大洋dMS海—气通量的估算方法进行讨论,分析南大洋表层海水dMS的分布特征及南大洋dMS海—气输送通量,对南大洋dMS海—气交换过程的控制因素进行探讨。Dimethylsulphide(DMS) is an important marine biogenic gas and can be released into atmosphere through sea-air gas exchange.The oxidants of DMS in atmosphere are the main compounds of pristine marine sulphate aerosols and would affect the global climate change finally.Almost all the atmospheric DMS,about 90%,comes from the ocean.The southern ocean,which consists about 20% of the whole ocean area,is one of the largest atmospheric DMS sources.In contrast with the other oceans,the Southern Ocean appears great spatial and temporal variability of surface seawater DMS.In addition,there are the complex hydrography system,variable sea ice condition and various biologic activities in the Southern Ocean as to make survey and understand DMS as well as its controlling factors most difficult.Moreover,it is significant to integrate the DMS sea-ice exchange processes and its controlling factors studies.In order to develop survey and research on the sea-air DMS exchange and biogeochemistry processes,estimate methods of the sea-air DMS fluxes will be reviewed,characteristics of the spatial and temporal distribution of surface seawater DMS will be discussed and the sea-air DMS flux in the Southern Ocean will be assessed.Finally,major controlling factors of DMS sea-air DMS processes will also be analyzed.南北极环境综合考察与评估专项项目“十二五”极地专项项目——专题4“南极周边海域海洋化学与碳通量考察”(编号:CHINAER2012-01-04); 国家自然科学基金重点项目“南大洋N2O源汇格局:驱动机制及其对海洋N2O收支的影响”(编号:41230529)资

虹鳟免疫诱导型基因Cathelicidin2启动子功能分析

本研究通过实时荧光定量PCR实验对虹鳟(Oncorhynchus mykiss)Cathelicidin2(Cath2)基因的转录模式进行了分析。结果显示,该基因在鳃、头肾等与机体免疫防御功能密切相关的组织内转录,在细菌和病毒感染后,转录水平均显著升高。对基因上游调控序列进行启动子和转录因子结合位点预测,发现该启动子具有真核生物典型的TATA盒和CAAT盒结构,基因上游直至第一内含子区域内,密集存在多个免疫相关转录因子结合位点,其中,2个核因子κB(Nuclear factor kappa B,NFκB)预测结合位点均位于核心启动子正链区域。在草鱼(Ctenopharyngodon idellus)肾组织细胞系内,绿色荧光蛋白和萤火虫荧光素酶基因都能够在该启动子驱动下表达,表明其具有启动子活性,且启动子活性在受到免疫诱导后增强,包括细菌脂多糖(Lipopolysaccharides,LPS)模拟的细菌感染和聚肌胞苷酸(Polyinosinic polycytidylic acid,Poly I:C)模拟的病毒感染。双荧光素酶报告基因检测显示,启动子活性在与NFκB转录因子表达时,增强至4.39倍,证明Cath2基因受NFκB通路调控。研究表明,虹鳟Cath2基因能够在多种免疫刺激诱导下表达,其启动子可以应用为免疫诱导型的基因工程元件,驱动外源免疫基因在鱼体内适时表达,抵御外界病原感染,同时,避免非必要条件下的过度表达形成生长负担。国家科技支撑计划项目(2015BAD25B01);;中国水产科学研究院基本科研业务费专项(2015C007)共同资助~

Ultimate Strength of High Strength Concrete Columns Reinforced with Concrete Filled Steel Tube Under Axial Compression and their Reliability Analysis

为了探求一个合理的设计公式来计算带圆钢管的劲性高强混凝土柱在轴压下的极限强度,完成了包含13个短柱试件在内的轴心受压试验以研究该类柱在轴压下的破坏模式和极限强度.试验结果表明,在荷载作用下,直到荷载接近极限值时,柱中钢管、纵向钢筋以及混凝土三者之间的纵向应变基本上是协调的,计算结果与试验结果吻合良好,因此可以采用叠加原理来计算带圆钢管的劲性高强混凝土柱在轴压下的极限承载力.此外,分析了该极限承载力计算公式的可靠度水平.分析结果表明,该承载力计算满足GB50068-2001对构件可靠指标的要求.This paper aims at developing a rational design formula to predict the ultimate strength of high strength concrete columns reinforced with concrete filled steel tube (HSCCRST) under axial compression. In order to investigate the failure mode and the ultimate strength of the columns under axial compression, experimental tests of 13 specimens under axial compression were performed. Test results showed that the longitudinal strain of the steel tube, the longitudinal reinforcement, and the concrete in the column were all compatible under loading until the load applied was close to the ultimate load. Therefore, the ultimate strength of HSCCRST could be calculated in the principle of superposition. In addition, the reliability level of the columns under axial compression designed following the proposed formula was investigated. Analysis results indicated that the reliability indexes of the columns designed following the proposed formula satisfied the demand of Unified Standard for Reliability Design of Building Structures (GB 50068-2001), National Standard of the People's Republic of China.国家自然科学基金资助项目(50378034
