简介：纸介绍一个词法模型和它的申请的发展给试验性的模型河。模型考虑隧道移植的关键进程，包括床变丑，河岸失败并且弄湿并且弄干。在拐弯的第二等的流动在侧面的沉积运输起一个重要作用，它进一步影响隧道移植。一个新公式被导出预言近床的第二等的流动速度，速度的大小在被连接到侧面的水水平坡度。因为仅仅非连贯的沉积在当前的学习被考虑，河岸失败基于休息的沉没角度的概念被建模。弄湿并且弄干的过程用一个存在方法被建模。在为各种各样的分泌物的数字模型预言和试验性的观察之间的比较被做了。模型预言隧道平面形状和代表性的形状与实验室观察通常同意很好，这被发现。情形分析也被执行在隧道迁居过程上调查第二等的流动的影响。它证明如果第二等的流动的效果被忽略，在侧面的方向的隧道尺寸将严重被低估。

简介：土壤侵蚀，包括土壤分开，运输，和免职，是重要动态土地表面过程之一。磁性的tracer方法是为学习土壤侵蚀过程的一个有用方法。在这研究，磁性的tracers的五种类型用磁盘使成粒状的方法与好土壤，苍蝇灰，水泥，火山灰成胶状黏土，和磁性的粉末(减少的铁粉末)被做。tracers一致地与土壤被混合并且用模仿的降雨和流入实验在实验室测试了模仿interrill和土壤侵蚀的小河部件，为了选择能被用来由雨点和表面的腐蚀力量学习分开和免职的至少一tracers，在一个斜坡上水流动。结果证明有高磁性的危险性和大量尺寸的磁性的tracers的五种类型有0.99-1.29gcm−的一个范围；3大批密度。在interrill和小河实验，分别地，由组成了的tracersFC1和FC2在1:1和2:1的比率飞灰和水泥自从沉积的磁性的危险性接近了，与土壤粒子在阶段被搬运是uneroded和在沉积和磁性的tracersFC1和FC2的分开之间的回归方程的斜坡的土壤的离20的期望的价值很靠近，它是原来的土壤/踪迹比率。斜坡上的分开和免职能被磁性的危险性差别精确地反映。在磁性的危险性的变化取决于免职或分开是否发生了。然而，分别地，在1:1和2:1的比率由苍蝇灰和火山灰成胶状黏土组成了的由好土壤组成了的tracerFS和tracersFB1和FB2都是为土壤侵蚀学习不合适自从在沉积和tracer之间没有一致关系，为增加的分开流量总计。因此，tracersFC1和FC2能被用来走水路学习土壤侵蚀。

简介：AbstractBrucellosis is an important zoonotic infectious disease and is an important public health problem that causes serious economic consequences to the livestock industry. Brucella spp. comprise one of the most common pathogens causing laboratory-acquired infections (LAIs) and are becoming an increasingly important biosafety issue. To understand the significance of Brucella LAIs in China, related papers were search based on three Chinese databases (CNKI, Wanfang, and VIP), as well as PubMed. After assessment, 37 total cases were evaluated, including 27 students, seven laboratory technicians (one pregnant), two housekeeping staff, and one instructor. The age, sex, incubation period, pathogen detection results, and potential routes of infections were collected and analyzed. All LAIs occurred due to improper operations, inadequate biosafety training, and substandard laboratory safety conditions. Therefore, it is urgent to establish a comprehensive and systematic biosafety prevention/control system in laboratories to protect staff members from accidental exposures and LAIs; further, possible risks and control measures for the management of such infections were proposed.
