学生公寓寝室防盗系统的设计与实现

针对学生公寓宿舍防盗需要,设计一款远程遥控智能防盗系统。该系统使用51单片机和PIC单片机组网,以菲涅尔镜感应信号作为触发信号,发出警报预警、以及短信通知宿舍人员及公寓管理员,进而达到实时报警。系统利用单片机节点组网,可进行多房间的同时监控。     

导数光谱法同时测定污水中微量铜和锌

本文研究了以５－Ｂｒ－ｐＡＤＡＰ作显色剂，利用三阶导数光谱法，在碱性介质中同时测定铜和锌。该法测得铜、锌的表观三阶导数摩尔吸光系数分别为１．０×１０￣５和３．０×１０￣５，同时解决了谱带相互重叠干扰的问题。对石油化工厂污水进行测定，得到满意结果。     

二阶导数光度法同时测定微量镍和铜的研究

用２－（２－噻唑偶氮）－５－二甲氨基苯甲酸作为显色剂，在ｐＨ５．６，波长在６２０ｎｍ和５９０ｎｍ处，用于阶导数光度法，同时测定微量镍和铜。回收率镍为１００％￣１０２％，铜在９２％￣１０５％，Ｎｉ＾２＋、Ｃｕ＾２＋在０￣１６μｇ／２５ｍｌ均呈线性关系。     

电生溴库仑滴定法直接测定渣油中硫醚硫的研究

本文提出了在甲苯－冰乙酸－乙醇－ＮａＢｒ电解液中电生溴库仑滴定电位法指示终点直接测定渣油中硫醚硫的新方法。该电解液对渣油样溶解性能好，终点电位突跃大，结果准确。     

Continuous Order Homomorphism and bi-continuous Mapping

The relation of LFtopology on set X to the classical topology is always important for us to understand LFtopology. In this paper, we construct a bitopological space from a LFtopologial space,and we show that for a continuous order homomorphism between two LFtopological spaces there is a correspondent bicontinuous mapping between the constructed bitopological spaces.Let X be a set,L be a fuzzy lattice,use L~x denote all the fuzzy subsets of X use π_x denote set X×{L\{ O, 1} }, P(πx) is power set of π_x. Now we first define mapping, a of π_x into itself as following:
