虚拟现实技术及其在高校化工教学中的应用

虚拟现实（简称VR）是以沉浸性、交互性和构想性为基本特征的计算机高级人机界面。目前,作为一种全新的立体化教学手段,虚拟现实技术已应用于化工机械、化工工艺等课程的辅助教学。它可以逼真地向学生展现那些采用传统教学手段难以描述的内容,如设备内部构造、化学反应过程等,学生也可以自主地对虚拟对象进行观察和操作。教学内容生动,教学场景逼真,教学效果突出。实践表明,虚拟现实技术可解决当前化工教学面临的诸多问题,应用前景广阔。     

数字地图制图中居民地和道路关系处理

为了解决数图转换过程中要素之间的关系,基于国家基础地理信息,根据现有居民地分类情况,总结了数字制图环境下居民地与道路之间的关系,主要包括依比例尺、半依比例尺及不依比例尺居民地和道路之间的关系;结合国家1:250000和1:50000基础地理信息及不同比例尺数据采集成果,详细给出了不同情况下居民地和道路之间关系的处理方法,主要包括调整图层显示顺序、删除重复采集数据及移位等;基于Vc++和Oracle数据库,就国家1:250000和1:50000中居民地和道路之间关系的自动处理进行了实验。实验表明,利用此方法,对同类问题的解决具有一定的参考价值。     

阿托伐他汀对无症状性脑梗死二级预防的疗效观察

目的研究阿托伐他汀对无症状性脑梗死二级预防的临床疗效。方法将300例经头颅CT或MRI证实有梗死的无症状性脑梗死病人随机分为治疗组和对照组。治疗组用阿托伐他汀10 mg qn,对照组不用阿托伐他汀,采用其他治疗,如生活方式调整、控制血糖、血压等。进行双盲对照治疗3 a,观察两组病人症状性脑梗死的发生率和不良反应,并作统计学分析。结果治疗组症状性脑梗死3 a发生率(5.3%)明显低于对照组(14.7%),P0.05。结论阿托伐他汀对无症状性脑梗死二级预防的临床疗效确切。

Chaotic Genetic Algorithm-Based Forest Harvest Adjustment

Forest harvesting adjustment is a decision-making, large and complex system. In this paper, we analysis the shortcomings of the traditional harvest adjustment problems, and establish the model of multi-target harvest adjustment. As intelligent optimization,chaotic genetic algorithm has the parallel mechanism and the inherent global optimization characteristics which are suitable for multi-objective planning the settlement of the issue, Specially in complex occasions where there are many objective functions and optimize variables. In order to solve the problem of forest harvesting adjustment, this paper introduces a genetic algorithm to the Forest Farm of Qiujia Liancheng Longyan for forest harvesting adjustment firstly. And the experimental result shows that the method is feasible and effective, and it can provide satisfactory solution for policy makers.     

Using Acoustic Emissions to Detect Damage in Three-Dimensional Braided Composites

Three-dimensioual(3D)braided composites with better properties have been used in some particular industries.Some have had obvious signs of crack when they are braided.Others have had catastrophic failures occuring without warning.A new methodology for the analysis of failure modes in composite materials by means of acoustic emission techniques has been developed.The occurrence of fiber-breakage during tensile loading tests has been observed by the acoustic emission technology.Using acoustic emission technology is investigated as a means of monitoring 3D braided composites structures,detecting damage,and predicting impending damage.Stone of the findings of the research project were presented.     

The Synthetic Effect of Magnetorheological Finishing Technology: Analysis,Modeling,and Control

The controllable key factors in magnetorheological finishing device were studied to determine their influence on efficiency of magnetorheological finishing (MRF) and surface of MRF,as well as interaction between efficiency and surface. Based on theoretical and experimental research,the law of material removal was explored and a new process variable based material removal model (PVMR) was proposed. The experimental findings demonstrate that PVMR reveals the law of the material removal with introduction of three concepts and makes a material removal function z (yi) where the magnetorheological finishing process parameters are considered since they are easy to control and adjust. So the material function of this model is quadratic curve function which is readily suitable for stability and online control magnetorheological finishing.     

黄柏黄连素的压液提取和纯化

研究了压液提取法提取黄柏中的黄连素,并与常规冷浸法进行比较.用0.3%稀硫酸水溶液在压液和冷浸条件下分别提取20 min和24 h,将提取液过滤,滤液先用石灰乳调pH至12,过滤,滤液再用盐酸调pH至2-3,滤液中加入10%的固体氯化钠搅拌溶解,得黄连素粗品,再将所得粗品放入20倍量沸水中,加热溶解,放置过夜,制得黄连素精品.结果表明:压液提取所获产品收率高,纯度较低,而冷浸法所获产品收率低,纯度较高,综合看来,压液法提取黄柏黄连素经济可行.
