Research on the System of Administration Accountability and Governmental Executive Power

从对行政官员的问责开始，到行政问责法规的陆续出台，我国的行政问责制经历了一个逐步规范化的过程。社会各界对行政问责给与了极大的关注，希望这一新兴的制度能对政府的工作起到重要的监督作用。政府执行力是政府工作的生命力，政府执行力的提高是建设人民迫切需要的服务型政府的需要。加强对行政权力的监督是提高政府执行力的关键，而行政问责制是对行政权力进行监督的重要方式。 本文首先对现有的关于行政问责制和政府执行力的研究做了系统的综述，在此基础上作了简要的评论。 接着对西方发达国家的行政问责实践与政府执行的关系作了探索，立法机关和司法机关的问责、公众和新闻媒体的问责、行政机关内部的问责、在野党和利益集团的问责...Started form the accountability of government officials, some local governments have promulgated regulations about administration accountability, the system of administration accountability has undergone a gradual standardization process. The great concern has given to the system of administration accountability by different communities who hope this new system can play an important role in influe...学位：管理学硕士院系专业：公共事务学院公共管理系_行政管理学号：2005130063

油菜籽微波预处理的干燥动力学及模型研究Drying kinetics and model of rapeseed by microwave pretreatment

为了探明油菜籽微波预处理过程中的水分变化情况，建立油菜籽微波预处理干燥模型，对油菜籽在料层厚度12 mm、不同微波功率（1.0、1.5、2.0 kW）以及微波功率1.5 kW、不同料层厚度（6、12、18 mm）下预处理后的含水率、水分比和失水速率的变化情况进行了研究，并以常用的3种干燥模型指数模型、单项扩散模型和Page模型进行了数据拟合。结果表明:微波功率越高、料层越薄，油菜籽水分流失越快，微波预处理时间越短；微波预处理过程中油菜籽水分变化情况与Page模型拟合度最好。 In order to clarify the moisture changes during rapeseed microwave pretreatment process and establish rapeseed microwave pretreatment drying model, the changes in moisture content, moisture ratio and water loss rate of rapeseed after microwave pretreatment were investigated at a layer thickness of 12 mm and different microwave powers (1.0,1.5,2.0 kW), and at a microwave power of 1.5 kW and different layer thicknesses (6,12,18 mm), and data fitting was carried out with the common drying models of exponential model, single diffusion model and Page model. The results showed that the higher the microwave power and the thinner the material layer, the faster the moisture loss of rapseed and the shorter the pretreatment time. The changes in moisture of rapeseed during the microwave pretreatment process fitted best with the Page model

中国高等植物受威胁物种名录

2008年,环境保护部和中国科学院联合启动了《中国生物多样性红色名录——高等植物卷》的编制工作。通过这项工作,我们依据IUCN濒危物种红色名录标准对中国野生高等植物的濒危状况进行了全面评估,编制了中国高等植物红色名录。2013年9月,该名录以环境保护部、中国科学院第54号公告形式发布,即《中国生物多样性红色名录—

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
