In this work, nanostructure samples of La1-xCaxMnO3（x=0.2、0.3、0.4、0.5）were prepared by hydrothermal-precipitation method . The structural characterization of the powder samples were done by X-ray diffraction. XRD patterns showed that all the samples ate single perovskite-type phase withoutother impurity or secondary phase. The shape and size of samples were performed on Scanning Electron Microscopy. SEM photographs investigated that temperature of hydrothermal effects the phase of samples and alkalinity of the reaction mixture by ΔTad-T curve measurement device at low magnetic fielded

本论文采用水热共沉淀退火法制备了La1-xCaxMnO3（x=0.2、0.3、0.4、0.5）系纳米结构，用X射线衍射仪确定产物为单相钙钛矿结构，无任何杂峰及第二相；用扫描电子显微镜与透射电子显微镜分析了产物的大小和形貌，发现水热温度对产物的形成起决定作用，随着温度的升高，产物由薄膜状向丝状转变，而溶液的碱度可控制产物的形貌和大小，当碱度为6.35mol/L，水热温度为240 C时，La0.6Ca0.4MnO3的主要形貌为纳米丝并有少量纳米颗粒，纳米丝平均直径为40nm；最后测量了粉末样品在低磁场（1.4T）下的磁热效应，发现水热共沉淀退火法制备样品的最大绝热温度明显高于球磨法制备样品的最大绝热温变。

This dissertation fistly introduces appearance, definition, development process, functions and status of MES, also analyses methods and existent problems of MES production scheduling; as follow, in the background of CY_MES (a enterprise's Manufacturing Execution System), introduces main function and buildup of its support platform– SIMATIC IT, and whole structure of CY_MES; afterwards, for special production instance of the enterprise, designs production scheduling system software structure, function structure, data structure of order and entry and realization of silk production and packing production scheduling based on SIMATIC IT; finally, after contrast of many modeling methods and careful research of silk production flow of the enterprise, selects Petri net to model the silk production scheduling, for the sake of avoiding many error chromosomes, improves on the basic genetic algorithm, uses sigle unit genetic algorithm to optimize the Petri net model, lists the contrast of scheduling results.

本文首先介绍了MES的产生、定义、发展历程、功能及其发展现状，同时也分析了MES生产调度问题的各种解决方法及其存在的问题；接着以CY_MES为背景介绍了其支撑平台——SIMATIC IT平台的功能及其各组成部分，以及CY_MES的SIMATIC IT整体解决方案；紧接着在SIMATIC IT平台基础上，针对该烟厂的生产实际情况，设计了CY_MES生产调度系统的软件结构、功能结构、工单和子工单的数据结构和制丝与卷包生产调度的实现方式；最后，在比较了各种生产调度建模方法的利弊和对该烟厂制丝生产工艺流程深入研究后，利用Petri网建立了制丝生产调度模型，为了避免大量无效个体的出现，对基本遗传算法进行了改进，采用单个体遗传算法对这个Petri网模型进行了优化，并给出了调度结果的对比。

The van Dyck reference gave her the idea for playing with lace in pale wool embroideries, laser-filigree cuffs, and buttons—all elements that contributed to her redrawing of the outlines of Valentino's classic suitings with curved, slightly space-age volumes.

Van Dyck的作品给她带来了一丝灵感，素色刺绣上的蕾丝，激光金银丝袖口，精美的纽扣以及流线的体积感让她重现了Valentino经典服饰的风采。
