In a severe accident of a nuclear power reactor,coolant channel blockage by solidified molten core debris may significantly influence the core degradations that follow.The moving particle semi-implicit(MPS)method is one of the Lagrangian-based particle me
The reliable operation of flexible display devices poses a significant engineering challenge regarding the metrology of high barriers against water vapor.No reliable results have been reported in the range of 10-6g·(m2·d)-1,and there is no standard ultra-
Analysis of molten metal spreading and solidification behaviors utilizing moving particle full-impli
To retrieve the fuel debris in Fukushima Daiichi Nuclear Power Plants(1F),it is essential to infer the fuel debris distribution.In particular,the molten metal spreading behavior is one of the vital phenomena in nuclear severe accidents because it determin
为了控制石灰石生产加工过程中岩粉的产生及分析其成因,利用邦德功指数和研磨性分析了石灰岩的主要特性,结合灰岩粉的主要来源,提出了针对性的岩粉控制措施,并通过灰岩矿爆破试验进行了验证.研究结果表明:石灰石相较于其他岩石更易产生岩粉,其主要来自于爆破形成的粉碎区,机械破碎中的矿石整形,钻孔岩屑及软弱夹层;通过优化爆破破碎过程,采用空气间隔不耦合装药、现场混装装药和合理优化爆破参数等方式,可以控制粉碎区大小,使爆破级配更为均匀,从而减少爆破岩粉.
Clinical Characteristics and Outcomes of Severe or Critical COVID-19 Patients Presenting No Respirat
It is difficult to identify suspected cases of atypical patients with coronavirus disease 2019(COVID-19),and data on severe or critical patients are scanty.This retrospective study presents the clinical,labora-tory,and radiological profiles,treatments,and
A comparative computational fluid dynamics(CFD)study was conducted on the three different types of pressurized water reactor(PWR)upper plenum,named TYPE 1(support columns(SCs)and control rod guide tubes(CRGTs)with two large windows),TYPE 2(SCs and CRGTs w
The Sichuan-Tibet Railway is facing extra-ordinary challenges in terms of construction,operation,and maintenance because of its extremely complicated natural environment and geological conditions.Conse-quently,countermeasures are necessary and urgent to e
为了解决爆破振动信号的处理精度极易受到噪声信号的干扰的问题,在局部均值分解法(LMD)和总体平均局部均值分解法(ELMD)的基础上,提出了利用自适应互补集合局部均值分解方法(CELMDAN)分解原始信号,然后采用小波阈值法对获得的乘积函数(PF)分量进行去噪,提高了爆破振动信号去噪的精度.结果表明CELMDAN-WT方法有效地识别破振动信号中的噪声信号,实现了信号与噪声的分离,具有良好的自适应性,在爆破信号去噪中有良好的效果.
Optical deep learning based on diffractive optical elements offers unique advantages for parallel process-ing,computational speed,and power efficiency.One landmark method is the diffractive deep neural net-work(D2NN)based on three-dimensional printing tec
Effects of Three-Dimensional Platform Stiffness and Layer Dimensions on Separation of Carcinoma Cell
Cancer cell separation is highly desirable for cancer diagnosis and therapy.Besides biochemical methods,engineered platforms are effective alternatives for sorting carcinoma cells from normal cells based on their unique properties in responding to the phy
