Design and Implementation of School Blog System Based on B/S

随着互联网的发展，动态网页技术也已经广泛应用。本文主要研究如何运用ASP.NET动态网页技术进行校园博客系统的设计和开发。 博客是一种网络媒体的载体，最早的博客也被称为网络日志。相较于以往的网络载体如BBS、论坛等，博客更带有个人色彩，可由博客主人自由支配。相对于以往的个人主页，博客自由度更高，更简单的操作，使得其进入的门槛降低，这也就为其发展带来了较大的优势，大大提高了其普及速度和广度，并成为网络媒体相当重要和不可分割的一部分。 作为年轻人为主体的当代大学生，思想日趋活跃，不少同学都有属于自己的博客。针对当代大学生的状况，不少高等院校都在思考如何运用博客做好教育工作,而利用博客对大学生进...With the wide application of Internet, dynamic webpage technology has been widely used. This paper mainly described how to use ASP.NET dynamic webpage technology to design and develop campus blog system. The blog is a kind of network media carrier, the earliest blog also known as web log.

Effects of heating rate on fast pyrolysis of cut filler of cigarette

为考察升温速率对卷烟烟丝快速热解行为的影响,采用热重-质谱联用技术对卷烟烟丝在不同升温速率(200 K·min~(-1)~800 K·min~(-1))下的热解特性进行研究,并建立了不同升温速率下卷烟烟丝的快速热解动力学模型。结果表明:(1)随着升温速率的升高,烟丝各主要成分热分解温度区间的叠加程度、热解速率以及释放特性指数均呈递增趋势,且有不同程度的热滞后现象。(2)引入升温速率校正因子的动力学模型能够克服热滞后所引起的动力学参数偏差,可以更好地预测不同升温速率下卷烟烟丝的快速热解行为。(3)高升温速率下,热解烟气产物中质荷比(m/z)为56(丙烯醛)、79(吡啶)、84(烟碱)、94(苯酚)和117(吲哚)的化合物释放量减小。在高升温速率下卷烟烟丝的快速热解特性与卷烟燃烧的真实状态更为接近,建立的卷烟燃烧数学模型更加准确。In order to study the effects of heating rate on fast pyrolysis of cut filler of cigarette, TGA(Thermogravimetric Analyzer) combined with QMS(Quadrupole Mass Spectrometers) was applied to investigate the pyrolysis characteristics of cut filler of cigarette at different heating rates(200 K·min~(-1)-800 K·min~(-1)), and a kinetic model for the fast pyrolysis of cut filler at different heating rates was developed. The results showed that: 1) With the increase of heating rates, thermal decomposition overlap region, mass loss rate and devolatilization index of each main component in tobacco were raised. Meanwhile, thermal lags of different extents were also observed. 2) The kinetic model overcame the deviation of kinetic parameters caused by thermal lag via introducing a heating rate correction factor, and predicted the fast pyrolysis behaviors of cut filler at different heating rates more accurately. 3) The release of pyrolysis products, such as acrolein(m/z=56),pyridine(m/z=79), nicotine(m/z=84), phenol(m/z=94) and indole(m/z=117) decreased with the increase of heating rate. The fast pyrolysis characteristics of cut filler are closer to the real state of cigarette combustion and the developed mathematical model for tobacco pyrolysis kinetics is more accurate at high heating rate.福建省中烟工业有限责任公司科技创新项目“卷烟燃烧数学模型的建立及其在卷烟减害中的应用”(FJZYJH2013025

Improvement of Segmentation Correction Model Based on Local Features

基于局部特性的分割校正模型能够在图像分割的同时实现对非均匀场的校正,从而对灰度不均匀图像有较好的分割效果,然而,该模型具有局部特性,且采用多相分割,使得活动轮廓曲线对初始位置较为敏感,且分割速度较慢。针对该不足,通过引入自适应距离保持水平集算法,采用分割校正模型与自适应距离保持水平集相结合的方法,提出一种新的快速分割算法。实验结果表明,该算法可摆脱初始轮廓的限制,避免在分割灰度不均匀图像时边缘泄漏和分割不足现象,并且具有分割快速的特点。Segmentation correction model based on local features can implement the correction of intensity inhomogeneity images,for which has better segmentation effect,but with the local features of the proposed model,and using multiphase segmentation,so that it is sensitive to the initial position of the active contour curve and the segmentation is slow.Aiming at the shortage,a new fast segmentation algorithm is proposed by introducing Adaptive Distance Preserving Level Set(ADPLS) algorithm,combining the segmentation correction model and adaptive distance preserving level set method.Experimental results show that the improved algorithm not only gets rid of the influence of the initial contour,but also avoids the edge leakage and segmentation shortage phenomenon,maintains the fast segmentation.福建省自然科学基金资助项目(2008J0312
