Introduction:All countries face the potential threat of imported polioviruses,including both wild type and circulating vaccine-derived *** response,we conducted a province-level assessment in China to evaluate the risk of importation and transmission of type 1 wild poliovirus(WPV1)and type 2 vaccine-derived poliovirus(VDPV2).Methods:Distinct risk assessment tools for WPV1 and VDPV2 were employed,incorporating three primary indicators—population immunity,poliovirus surveillance,and importation ***1 was assessed using 13 secondary indicators,whereas VDPV2 utilized 21 secondary *** used comprehensive provincial data from the preceding five ***(S-values)were derived from the secondary indicators’criteria and ratings,and used to classify the provincial-level administrative divisions(PLADs)into three risk categories:high,medium,and *** top 10%of PLADs were designated as highrisk,with the remaining provinces equally distributed into medium-and low-risk ***:In 2023,Xizang,Qinghai,and Xinjiang PLADs faced the highest risk of WPV1 importation and transmission;Xizang,Shaanxi,and Hainan PLADs were at the greatest risk for VDPV2 importation and ***:Risk assessment for VDPV2 importation and transmission has identified a distinct set of high-risk provinces compared to those identified by WPV1 risk *** and proactive response measures tailored to the specific risks should be implemented to maintain China’s polio-free status.

This article introduces biodenittification rule of several operation in SBR system. Theresults show that sequencing aeration in SBR meets the needs of oxic and anoxic conditions ofbio-denitrification, and it is a promising bio-denitrification technique. It is the first discover thatduring the treatment of brewery wastewater, when the brewery wastewater is added in the activatedsludge, its denitrinfication rate is faster than methyl alcohol added. This experimental result has greatsignificance. It is suggested that adding original brewery wastewater shall be first considered inbio-denitrification of several kinds of wastewater. Altenlative operation of aeration and mixation,namely nitnfication and denitnfication, has high denitnfication efficiency.

针对火电厂石膏旋流器分级效果不理想的问题,设计具有分离块和隔板的新型入口,以改善石膏旋流器的工作性能。采用Fluent软件,应用Reynolds应力模型（RSM）与离散相模型（DPM）模拟新型入口中不同粒度颗粒的运动情况,模拟结果表明：随颗粒粒径增大,颗粒的运动半径与运动距离均增大,不同粒径颗粒在新型入口内能实现初步分级。对普通入口与新型入口石膏旋流器分别进行性能实验,获得不同工况下生产能力、出流浆液密度以及旋流器分级效率等指标参数,经比较可知,采用新型入口后,石膏旋流器底流质量浓度明显增大,10~30μm石膏颗粒的分级效率有显著提高,最大增幅可达15%,同时,6μm以下石膏颗粒的底流夹细现象也有一定程度的改善,但由于入口段流动阻力增大,生产能力略有下降。

采取对比的方法将Si IGBT/Si FRD模块与Si IGBT/SiC SBD模块静态及动态特性进行了测量与分析。测试表明,将Si IGBT模块中Si FRD替换为SiC SBD后开关损耗减小明显,提升效率的同时可大大提高功率模块的工作频率,降低系统体积。为了解释Si IGBT/SiC SBD混合模块开通过程中电流电压振荡现象,本文对模块开通与关断过程中电流的流通路径进行了对比,用以解释产生开通振荡的原因。分析中发现,开通振荡主要来自于模块封装杂散电感与IGBT输出电容及SiC SBD结电容产生的LC谐振。SiC SBD由于结电容较大而导致开通振荡较为明显。因此,为了提高SiC器件系统的可靠性,需要找到一种低电感封装技术,满足SiC器件封装要求。
