Regional coordination control for optimization of urban traffic

针对目前我国城市交通区域控制的研究现状,应用群决策理论和模糊控制理论,对整个城市区域交通建立协调二级模糊控制模型。以相邻交叉口之间的车流量信息和预测剩余时间周期为模糊控制器输入,由二级模糊控制器的输出控制下一时刻的绿灯相位,从而调整控制子区内相邻交叉口上下游之间的交通流和集散程度,最终实现对控制子区的宏观区域协调控制.In view of the present research status of urban traffic zone control in our country, by using the group decision theory and fuzzy control theory, to the whole city area, the secondary fuzzy control model is established.The adjacent intersections traffic information and predict remaining time period are used as the input of the fuzzy controller, the secondary fuzzy controller's outputs control the green light phase of the next moment, to adjust the control zone between upstream and downstream adjacent intersection traffic flow and distribution.Finally the macro regional coordination's control can be realized

TLR4的表达与急性胆道梗阻时内毒素致小鼠肝脏损伤的关系

目的探讨急性胆道梗阻时内毒素损伤小鼠肝脏的机制及其与TLR4表达的关系。方法雄性C57BL/10J(WT)小鼠42只,随机分为生理盐水组(NS组,n=21)、内毒素处理组1(LPS1组,n=21),C57BL/10ScnJ(TLR4-/-)小鼠21只,为内毒素处理组2(LPS2组)。3组均行胆总管结扎术,LPS1、LPS2组小鼠于胆总管内注射LPS(8ng/μL,10ng/g体重),NS组注射同等剂量的生理盐水,术后6、12、24h采集标本,RT-PCR检测肝脏组织TLR4mRNA的表达情况,全自动生化分析仪检测血清ALT、TBIL、DBIL水平,ELISA法检测血清TNF-α、IL-6的水平。病理观察肝脏损伤情况,免疫组织化学染色观察肝脏NF-κB的表达。结果 LPS1组与NS组比较肝脏组织TLR4mRNA在6h时表达已有升高,于24h达高峰,ALT、TBIL各时点均明显升高(P<0.01),TNF-α、IL-6表达亦增高(P<0.01),LPS1病理损伤程度较NS组重,免疫组化显示术后24小时NF-κB在LPS1组可见肝细胞明显的核表达。LPS2组与LPS1组比较各血清学指标均明显下降,病理损伤减轻,24h时肝细胞NF-κB核表达较少。结论在急性胆道梗阻时LPS可以加重肝脏组织损伤和机体炎症反应,可能与TLR4的表达增高及NF-κB的表达有关。阻断LPS-TLR4信号通路可以减轻LPS引起的机体损伤

[[alternative]]Metal surface adhesion promotion for corrosion control with organic/inorganic composites

碩士[[abstract]]本研究利用較具環保性且鐵片不需複雜的前處理過程的單寧酸(Tannic acid)能與鐵金屬形成穩定鐵之錯化合物的特性，將其應用在鐵金屬表面之防蝕塗佈上，底漆(Base coat)以自由基硬化型環氧樹脂(UV-Epoxy)添加鋅粉和三羥甲基丙烷三丙烯酸酯(Trimethylolpropane triacrylate, TMPTA) ，以不同比例混合後，使用旋轉塗佈(Spin-coating)塗佈在金屬表面上後，以照射紫外光來產生自由基使混摻的化合物產生交聯，其不僅是鋅金屬與單寧酸產生穩定錯化合物鍵結，且因加入的TMPTA和UV-Epoxy產生架橋，而在金屬表面上形成緻密穩定的表面塗層。接著再進一步塗佈具疏水性官能基的面漆(Top coat)，行紫外光交聯後，讓金屬、底漆與面漆產生緊密的結合，使得塗佈的底漆與面漆緻密覆蓋於金屬上達到相當好的抗腐蝕效果。[[abstract]]An aqueous tannic acid solution is used as steel surface coating primer; This characteristic can form black stablely complex with steel metal. In this experiment, we modify different ratio of UV-Epoxy, TMPTA and Zinc powder as base coat, then we use spin-coating method to spread them on steel metals’ surface. After that we add appropriate amount of Photo-initiator(e.g. 1173) to UV-curing. Exposing in UV light produce free radicals which lead compositions to crosslinking. Then a top coat resins consists of hydrophobicity of UV-reactive UV-PU and a tri-acrylate UV-reactive diluent (TMPTA) as a reactive diluent are applied on metal surface as a top coat. A photo-initiator are added and cured respectively with UV-radiation. The treated steel metal surface coating properties has been evaluated by salt spray to exhibit its anti-corrosion. The best results in our experiments are that the top coat containing PDMS-function which could put in salt-spray test without corrosion more than 750 hours.[[tableofcontents]]總 目 錄

教师道德心理一体化发展：挑战与应对

学生发展核心素养要求提高教师道德心理一体化教育水平，呼唤教师道德心理一体化发展。当前，教师道德和心理问题在社会认识上、伦理认知上还存在一定的偏差，制约着教师道德和心理发展，教师道德心理一体化发展本身在教育层次、教育阶段上也存在一些不足。在道德心理对立统一的理论指引下，重塑教师道德心理一体化发展的对立统一关系，从而探索建构教师道德心理一体化发展在职前、职中、职后三阶段的培训培养模式。</p
