光催化降解染料废水的研究

在光催化剂的固定化技术的研究中,通过化学反应将比表面积很小的TiO_2引入多孔硅胶载体颗粒的表面,并经过高温处理以提高其催化活性。通过BET比表面积测定发现,制得的光催化剂TSO具有比表面积大、分散性高和二次污染小等优点。而光催化降解实际染料废水的研究表明,制得的光催化剂对实际染料废水有较好的降解效果,强氧化剂H_2O_2的加入对染料废水的降解有利。利用钛醇盐水解法可以制备大量负载型TiO_2光催化剂,对于实际废水处理有一定的借鉴作用。     

Sketch2Photo图像合成技术在医学影像诊断上的应用

随着数字化医学影像设备在医院的普及,在医院影像系统中都保留着海量的患者病情影像资料,快速提取和匹配是一个瓶颈。搜索一张图往往脑子里有图的大概样子,却不知道该往搜索框里打什么字。而对Sketch2Photo技术来说,只需要用鼠标描绘出个轮廓就可以得到结果。本文探讨了在现代医学影像诊断上的应用价值。     

GIA: design of a gesture-based interaction photo album

This paper describes a gesture-based interaction photo album (GIA) device which stores and manages digital images. It provides a natural interface—as if you are turning the pages of a photo album using gestural input on a touch screen. We feel that emotional satisfaction is more important than efficiency in this kind of task and requires a more natural user interface that is easily learned by novices. GIA demonstrates an innovative convergence between the digital and the analogue in this respect.

不同氧气浓度下光引发剂对UV油墨体系固化速率的影响

氧阻聚作用是影响UV油墨体系固化反应的重要因素.本实验针对氧气浓度对UV油墨体系固化速率的影响,设计制作了可以改变氧气浓度的UV固化装置,制备了一系列UV油墨样品,探讨了不同氧气浓度下光引发剂种类及其含量对体系固化速率的影响.结果表明:在测试范围内,UV油墨体系的双键转化率与氧气浓度有很大关系.在氧气浓度较低时,双键转化率较高;随着氧气浓度的增加,双键转化率呈明显下降趋势.以体系ITX/EHA为例进行研究,当光引发剂ITX含量在1％～10％之间变化时,光引发剂的含量越高,双键转化率越大,固化速率越高.     

各向异性材料应力应变分析方法的研究

由于各向异性材料的弹性常数随方向而变化 ,这就使通常用于各向同性材料的光弹性贴片法的基本方程失效。本文从光弹性贴片法的基本原理出发 ,给出正交各向异性板内任一点的应力计算公式 ,同时也提出了正交各向异性板厚度效应的修正系数。文中对带圆孔正交各向异性板孔边应力分布做了光贴片实验并与文献 [2 ]中的有关数值解进行了比较 ,验证了本文工作的正确性

全球光伏产业的加速发展

伴随着经济的发展、人们环保意识的提高，寻找新能源成为当前面临的迫切课题。新能源具有蕴藏丰富不会枯竭，安全、干净，环境友好性强等特点。由于太阳能发电干净，无公害，因此被公认为最理想的新能源，从德国、埃及、美国韩国等国家太阳能发电来看，光伏产业的发展相当迅猛，而这与这些国家的积极扶持的政策是分不开的，当然，最根本的还在能源安全，保护环境的迫切需要以及开发的成本逐渐降低等原因。     

Authenticating corrupted photo images based on noise parameter estimation

Photo image authentication is an interesting and demanding field in the computer vision and image processing community. This research is motivated by its wide range of applications, which include smart card authentication systems, biometric passport systems, etc. In this paper, we propose a method of authenticating corrupted photo images based on noise parameter estimation. The proposed method first generates corrupted images by adjusting the noise parameters in the initial training phase. This set of corrupted images and the noise parameters can be represented by a linear combination of the prototypes of the corrupted images and the noise parameters. In the testing phase, the noise parameters of the corrupted photo image can be estimated with a corrupted image and an original image. Finally, we can make a synthesized photo image from the original photo image using the estimated noise parameters and verify it with the corrupted photo image. The experimental results show that the proposed method can estimate the noise parameters accurately and improve the performance of photo image authentication.     

Relations between needs of friends and fiancés.

This study was undertaken to investigate complementarity and similarity of needs in mate and friendship selection. The Edwards Personal Preference Schedule (EPPS) was administered to 29 clusters of 6 Ss each. A cluster consisted of an engaged couple and a male and female friend of each fiancé. Evidence for similarity of needs in mate and friendship selection, but no consistent evidence for complementarity was found. Engaged couples were significantly alike on 8 of the 15 EPPS needs. In friendship pairings, females select female friends who are like themselves, males select male friends with few similar needs. The male fiancé selects the same type of woman as a friend and as a future spouse, but the female fiancée picks a male friend and a fiancé who are dissimilar. These findings indicate that different processes are involved in the formation of like-sex and opposite-sex pairs fulfilling different interpersonal roles.
