通过调制温度式差示扫描量热技术(MDSC)测定了玻璃纤维/环氧树脂预浸料在固化全过程不同方向上的比热容和热导率,并建立模型来描述比热容和热导率随温度和固化度的变化。未固化和完全固化时,预浸料的比热容和热导率随着温度的增大线性增加;在固化过程中受温度和固化度的双重影响,在固化反应前期,比热容和热导率有一个突变,在温度和固化度的作用下表现出先增大后减小的趋势。此外,通过混合定律和分段线性关系来描述比热容和热导率随温度和固化度的变化关系,结果有助于提高数值模拟中参数的准确性。

Increasing cases of human infections with the high pathogenic avian influenza virus H5N1 have raised great concern on potential human flu pandemics caused by H5N1. The two viral surface glycoproteins, the hemagglutinin (HA) and the neuraminidase (NA) proteins, are major antigens o H5N1. Introducing new mutations on these two pro teins is the major strategy used by H5N1 to expand host range and to avoid the recognition of host im mune systems. We analyzed the two surface proteins of H5N1 from Asian human patients and identified many new mutation sites, including a few that were unique to certain lethal strains. We also analyzed the distribution of mutations on different epitopes of the two surface proteins. A receptor-binding site tha might involve in the determination of host specificity of H5N1 was also found. Results reported here pro vided information for better understanding of the evolution trend of H5N1 genome in human.

This study investigated the occurrence,species,infectivity and removal efficiency of Cryptosporidium *** typical wastewater treatment *** from different process units were collected seasonally and synchronously from four wastewater treatment plants(WWTPs)in Northeastern *** Cryptosporidium oocysts were identified in most samples from both influent(97.50%)and effluent(90.00%)wastewaters of the four WWTPs,at an average density of 26.34 and 4.15 oocysts/L,*** overall removal efficiency was 84.25%,and oocysts were mainly removed(62.01%)by the modified secondary sedimentation *** Cryptosporidium species were identified in the effluent ***,***,and *** were the three most prevalent *** viability assays indicated no reduction of excystation rate during the primary and secondary wastewater treatments(varied in the range of 63.08%–68.50%),but the excystation rate declined to 52.21%in the effluent after ***,the Cryptosporidium oocysts showed higher infection intensity in the cold season(winter and spring)than that in summer and *** influences of environmental temperature on virulence factors of Cryptosporidium were further *** was observed that more extracellular secretory proteins were bound on the oocyst surface and several virulence genes were expressed relatively strongly at low temperatures,both of which could facilitate oocyst adhesion,invasion,and host immune *** research is of considerable interest since it serves as an important step towards more accurate panoramic recognition of Cryptosporidium risk reduction in WWTPs,and especially highlights the potential health risk associated with Cryptosporidium in cold regions/seasons.

Chinese Physics B 2022年第8期31卷 547-551页

作者： shiheng Cui Huashan Liu Hailong Peng School of Materials Science and Engineering Central South UniversityChangsha 410083China

We report computer simulations on the oscillatory of Cu Zr metallic glasses at zero temperature with different shear amplitudes. In small system a homogenous shear deformation is found, while in large system an inhomogeneous shear deformation is found with a shear band formed. Concomitantly, spatial correlation of irreversible displacement exhibits an isotropic and exponential decay in the case of homogeneous deformation, whereas a mixed power-law and exponential decay in the case of anisotropic and inhomogeneous deformation. By projecting the azimuthal-dependent correlation function onto the spherical harmonics, we found a strong polar symmetry that accounts for the emerged shear band, and a weaker quadrupolar symmetry that accounts for the elastic filed generated by Eshelby inclusions. By this, we conclude that the anisotropy and decaying formula of the plastic correlation are dominated by the homogeneity or inhomogeneity for the deformation in the metallic glasses.

传统控制系统研究都是基于阶跃响应的控制曲线进行分析。针对这种情况,提出一个更加有效、直观的对比分析方法来分析不同控制算法(普通PID和模糊PID)的控制效果。采用机电联合仿真方法,建立虚拟平台使得SolidWorks中的机械模型在运动时,LabVIEW的控制平台可实时监测控制系统的控制效果。结果表明通过LabVIEW和SolidWorks的联合仿真,既能实现控制算法对三维模型精准的运动控制,又实现了不同算法的运动效果对比。三维模型的运动曲线很直观地表明,模糊PID控制系统具有更少的控制响应时间和更好的运动速度稳定性。
