在<国务院关于大力推进职业教育改革与发展的决定>及教育部在2003年3月发出的<关于开展高职高专院校人才培养工作水平评估试点工作的通知>颁布后,全面推进了公安高职高专院校的建设工作.许多省市的人民警察学校相继升格为警官高等专科学校或职业警官学院,成为我国公安学历教育和在职民警培训的主要院校和基地.同时,我们也发现公安院校办学中的一些问题,如教育理念、模式、途径、方法相对滞后,理论与实践距离圈套,职业化教育特征不突出,教师队伍水平不一,科研成果量少质弱等.因此,从宏观上分析、研究、解决公安高职院校发展中的问题,推进高职院校的职业化步伐,就必须注意这样几个问题. 相似文献

To study the influence of slenderness on the axial compressive performance of autoclaved fly ash solid brick masonry columns, compression experiments were conducted on 12 samples of autoclaved fly ash solid brick masonry column and 4 samples of fired clay brick masonry column. The damage patterns and compressive performance were compared and analyzed. The experimental results indicate that the compressive bearing capacity decreases as slenderness increases from 3 to 18, and the compressive bearing capacity of the autoclaved fly ash solid brick masonry columns is lower than that of the fired clay brick masonry columns. The formulae for the axial compressive bearing capacity of autoclaved fly ash solid brick masonry columns were derived based on the experiments. The nonlinear FEA program ANSYS was adopted to simulate the behaviors of masonry columns. By comparing the simulation results and experimental results, it is shown that the simulation results agree well with the experimental ones. The rationality and applicability of the simulation results were verified. 相似文献

随着互联网和新媒体的发展,期刊的数字出版被业内专家和广大学者所关注,对于其的研究应运而生.与之相对应的传统期刊面临着改变自身适应新的产业形势的挑战.虽然传统期刊有着无法被取代的自身优势,即在内容的可信度、权威性、原创性等方面的优势,但无法避免承载着海量信息的新媒体,在时效性与信息量上对传统期刊造成冲击.传统期刊的数字出版业务是期刊在适应新的发展环境势在必行的举措.笔者以浙江省期刊为例,深入分析近五年浙江省期刊数字出版业务的发展现状,以此探索数字出版在传统期刊领域主要的影响因素、所遇到的困境及未来的发展前景. 相似文献

CFD Analysis of Gas Distributor in Packed Column--Prediction of Gas Flow and Effect of Tower Internals Geometry Structure 总被引：1，自引：0，他引：1
Computational fluid dynamics (CFD) simulations were carried out on the gas flow patterns of twin-tangential annular deflector gas distributor in the absence of liquid flow in a packed column (6.4 m in diameter), and the gas flow field in the column was presented close to reality on the whole. Furthermore, after ame-lioration of this gas distributor frame, turbulence energy and turbulence energy dissipation rate were both decreased greatly.Simulation results showed that the flow pattern and the distribution of gas flow were strongly affected by the column bottom frame; the proper column bottom frame could decrease the flow pressure drop greatly. Multifold factors, such as the column bottom geometry structure and distributor structure which affects the distribution capacity, must be considered. 相似文献
