植被覆盖度(Fractional Vegetation Cover,FVC)是刻划地表植被覆盖程度的一个重要参数,也是指示生态环境变化的重要指标之一。中国-东盟1km/5day的FVC数据集,采用像元二分模型和NDVI数据,按照不同气候类型、不同土地和植被类型分别采取不同的归一化植被指数(Normalized Difference Vegetation Index,NDVI)到FVC转换系数开发完成。与基于SPOT-VEGETATION数据生成的植被覆盖度产品GEOV1-FCOVER对比分析显示,本产品在时空连续性方面优于GEOV1FCOVER产品。利用甘肃黑河流域等实验区地面观测数据进行直接验证显示,本产品与地面实测数据一致性较好。

目的该文探讨超声侵入性操作检查患者的医院感染情况,并对其控制措施进行分析与干预。方法选取2015年2月—2016年2月在该院住院的患者4120例,将其中未接受超声侵入性操作的1980例作为对照组,另2140例接受超声侵入性操作患者为观察组,观察组患者采用全自动血培养仪对标本进行培养,对细菌的鉴定应用ATb系列半自动细菌鉴定仪,同时观察两组患者的医院感染率。病原菌的分布、相关医护人员对此操作管理制度的控制。结果选取的2140例行超声侵入性操作的患者中发生医院感染率为26例,占比例为1.21%,阴道b超的感染率为1.37%,行宫腔镜的感染率为1.32%,腹腔镜检查感染率为0.57%,行阴道b超及宫腔镜的感染率均高于行宫腔镜的感染率,差异具有统计学意义(P<0.05)。结论相关医护人员应对超声侵入性操作医院感染采取针对性控制措施,加强抗感染意识,进行控制措施教育,最大限度降低医院感染率。

A novel microstructural architecture consisting of Cr23C6 carbide spatial columns was created in solid components of Co-26Cr-6Mo-0.2C fabricated from powder by additive manufacturing using electron beam melting. These columns of carbides extended in the build direction and are formed by the x-y rastering of the electron beam to pre-heat and melt powder layers using CAD models. These microstructural architectures are similar to rapidly solidified/unidirectionally solidified structures created by heat extraction in the direction perpendicular to the build plane. These columnar carbide architectures were observed by optical metallography and transmission electron microscopy (TEM) and compared with intrinsic stacking fault microstructures observed in annealed components. The TEM analysis allowed the details of the carbide crystal structure and corresponding cubic morphology to be observed.

Nano-composite, perovskite ba(1- x - y)Sr(x)TiFe(y)O3, denoted as (bSTFe) in powder form was derived via sol-gel (SG) method followed by sintering at fixed temperature 750℃ for one hour. The chemical composition, morphology and structure of the powder samples were investigated by using X-ray diffraction (XRD), transmission electron microscope (TEM) and scanning electron microscope (SEM). The XRD characterization indicates formation of a cubic crystalline phase in the pure bST. A well defined perovskite phase with nano-crystallite sizes equal to about 34 nm was achieved from XRD for b10ST3F sample, while TEM study confirmed the obtained XRD results giving the following crystallite size value about 33.75 nm for the same sample. The dielectric A.C. conductivity was evaluated as a function of temperature and frequency ranging from 42 Hz up to 1 MHz.

以改进的KRC模型决定AGγ→α的方法,计算了Fe-C合金贝氏体相变可能机制:γ→α+γ1,γ→α+Fe3C以及γ→α（浓度相同）和α′→αb″（贝氏体铁素体碳浓度）+Fe3C的相变驱动力和长大（形核）驱动力.相变驱动力以γ→α+Fe3C为最大,γ→α+γ1次之,γ→α最小.由奥氏体转变成同成分铁素体（γ→α）的长大驱动力远小于γ→α+γ1的长大驱动力.在贝氏体形成温度范围内,γ→α的驱动力远小于切变机制所需的驱动力.0.1—0.55wt,%C合金在bs温度时γ→α+γ1的相变驱动力仅约—45Jmol-1.0.8wt %C合金在贝氏体形成上限温度（823K）时γ→α的相变驱动力为137Jmol-1,而α→α+Fe3C的相变驱动力为-527Jmol-1;两者相加,即在贝氏体铁素体析出渗碳体的情况下,相变总驱动力也仅有约-390Jmol-1.上述结果表明,贝氏体铁素体很难以切变机制形成和长大.
