基于Bang-Bang模糊自适应PID的干燥窑温度控制

为解决产品干燥窑温度控制过程中温度参数不易及时、准确调整的问题,该文提出了一种Bang-Bang(时间最优控制)模糊自适应PID复合控制器,利用Bang-Bang控制能最大限度的提高干燥窑温度的快速性和模糊自适应PID能提高干燥窑温度控制的准确性,使系统静态、动态都有比较理想的性能。建立干燥窑温度模型,并对该模型进行Bang-Bang模糊自适应PID控制和PID控制的仿真,两者比较结果:表明:Bang-Bang模糊自适应PID的响应明显比PID控制的响应效果优越。     

多用途化学实验信息化教学平台建设

随着实验教学示范中心建设进程的推进,各级各类化学实验室均承担了多类别的教学任务,同时信息化技术在化学实验教学中的应用也日益普遍,多用途化学实验信息化教学平台成为了迫切需要。在这种形势下,华东理工大学化学实验教学中心开发了相应的信息化教学平台,区别于常见的虚拟化学实验系统,该平台淡化对多媒体技术手段的过分追求,注重贯彻实验前预习、实验中帮助、实验后测试的全过程跟踪的实验教学理念,尤其是实验操作过程中每一步操作的跟踪记录,强调对多类别教学任务的适应性。

Volatiles from Ficus hispida and Their Attractiveness to Fig Wasps

Volatile compositions of receptive (ready to be pollinated), postpollinated, and postparasitized figs, and leaves of Ficus hispida were analyzed. Differences among them were examined, and the specificity of fig wasp attractiveness was investigated. Linalool was the major constituent of steam-distilled oil of either male or female receptive figs, while dibutyl phthalate was the major compound of the oils of postparasitized and postpollinated figs. In petroleum ether extracts, palmitic oil, and 9,12-octadecadienoic acid were the main constituents of male and female receptive figs, while hexadecanoic acid ethyl ester was the major compound of postparasitized and postpollinated figs. In dichloromethane extracts, linalool was the major constituent of male and female receptive figs, 1-hydroxylinalool was the major component of male postparasitized figs, and 1-hydroxylinalool and benzyl alcohol were the major constituents of female postpollinated figs. Bioassays with sticky traps showed that Ceratosolen solmsimarchal was attracted to dichloromethane extracts of male and female receptive figs and to petroleum ether extracts of female receptive figs, but was not attracted to dichloromethane and petroleum ether extracts of male postparasitized and female postpollinated figs. Figs were attractive to pollinating wasps only at the receptive stage. The volatile constituents of receptive figs were different from those of postpollinated or postparasitized figs. From a receptive to a postpollinated state, figs changed in their volatile composition. Some compounds disappeared or decreased in amount. These include linalool, linalool oxide, -terpeneol, and 2,6-dimethyl-1,7-octadiene-3,6-diol, which may act as the attractants of the wasps. Others increased in amount, or several additional chemicals appeared. These include dibutyl phthalate, 1-hydroxylinalool, and benzyl alcohol, which may be repellents of the wasps. That dichloromethane extracts of male and female receptive figs showed similar activities in attracting fig wasps indicates that receptive figs of both sexes are similarly attractive to fig wasps, which is further supported by their similar volatile composition. Leaf extract was not attractive to the wasps.

钕对AZ91镁合金组织及机械性能的影响

采用微观分析、机械性能测试及断口分析等方法研究了钕对AZ91-Nd镁合金(w(Nd)=0,0.1%,0.3%,0.5%,1.0%,1.5%)的微观组织和机械性能的影响。结果表明:Nd以固溶和金属间化合物(A l11Nd3)的形式存在时具有细化晶粒、抑制二次β相析出、使不完全离异共晶转化为离异共晶的作用;Nd通过固溶强化、析出强化和细晶强化增加了合金强度和硬度,并改善了塑性;加入Nd后合金的断裂机制从脆性解理断裂转变为准解理断裂。
