Design and Implementation of Party Construction Management System for a Railway Development Company

在国民经济中，铁路具有举足轻重的作用，而铁路企业的党建工作是企业管理中的一项重要内容。对于铁路企业来说，铁路具有线长、点多、人员散的特点，造成了党员地域分布散、工作时间差异大、党组织设置呈高度分散状态的局面。在此背景下，建立基于现代网络信息技术，构建面向大众开放、满足个性化需求的党建管理系统已成为现代铁路企业党建的趋势。一个设计合理、功能完善的铁路党建管理系统，有助于铁路企业整合党建信息资源，强化组织建设，增强组织活力和凝聚力，规避党建工作的随意性，增加党员的能动性，从而确保党建工作的正规化和科学化建设。 论文首先从系统目标、功能需求、性能需求、可行性这四个方面进行了需求分析；其次，从设计原...Railway plays an important role in the development of national economy. And the party construction is a key job in the railway company. For the railway company, it features long lines, many stations and scattered people, which lead to dispersed geographic distribution of parties, large difference of work time, and highly decentralized party organization. In the context, party management system, wh...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201323182

A Study on the First Logistics Loading Problem of Petroleum Company B

B石油公司是石油行业领导者，世界500强企业，也是最早进入中国市场，参与中国经济建设的外资成品油公司之一。目前，B公司成品油的一次物流包括货品由工厂成品仓配装发运至二级仓库，以及二级仓库库间配装转仓两个部分。当前一次物流的成本约占到B公司总物流成本的70%，并在未来仍有大幅上升的趋势。B公司的一次物流包括到诸多环节，配装是其中的重要组成部分，涉及从获取订单信息到车辆离库的全部操作。因此，挖掘B公司现有一次物流配装流程中的缺陷并做以改进，对提高B公司一次物流的整体效率具有积极的现实意义。 B公司一次物流的配装流程作业比较复杂，涉及的操作较多。本文对B公司当前一次物流配装的操作流程进行了分析，归...Company B is leader in the field of petroleum industry, Global 500, and also one of the first international petroleum companies entering Chinese market. The first logistics of petroleum company B contains two parts, including the distribution from first-level warehouse to second-level warehouse and the delivery among second-level warehouses. The cost of the first logistics,which is expected to sho...学位：工程硕士院系专业：管理学院_物流工程学号：1772010115111

Investigation of Species diversity of Cestodes of Fishes in Taiwan Strait and Preliminary Studies on Molecular Phylogeny of Cestodes

目前世界上已报道的绦虫有4000余种，有近半数种类的绦虫寄生于鱼类。大量海洋鱼类尚未被调查，同时许多绦虫之间的系统发育关系亦尚不清楚。本文作者正是针对这些问题而开展研究的。全文共分为两部分： 第一部分:台湾海峡鱼类绦虫物种多样性调查。作者于2003年4月至2005年3月调查了厦门市场常见的海洋鱼类，对检获的绦虫进行仔细的光学显微镜形态观察结合扫描电镜照片比较鉴定。本文共描述11种，分别隶属于三个目，五个科，七个属。其中有两个种类，经作者形态比较鉴定它们为新种，并建议建立一新属来容纳其中一种。具体结果名录如下： 1．日本副棘叶绦虫（ParaechinophallusjaponicusYama...There are nearly 4000 kinds of cestodes that have been reported from all over the world, and close to half of them have been found parasitizing in fishes. Presently many cestodes of marine fishes haven’t been investigated, and the phylogenetic relationships among them are still unascertained. The author try to contribute to solving these problems. The work can be wholly divided into two parts: Fi...学位：理学硕士院系专业：生命科学学院生物学系_动物学学号：20022602

An Empirical Research on Gender Differences of University Students' Entrepreneurial Motivation——Taking Xiamen University as an Example

文章采用问卷调查法,以厦门大学420名本科生为调查对象,从性别视角切入,对大学生创业意向进行简单统计,进而对阻碍无创业意向男、女大学生创业的重要因素,有创业意向男、女大学生的创业动机特征做了深入分析。Based on the data on entrepreneurial intention collected through a survey of 420 undergraduate students at Xiamen University by questionnaires,the author makes an in-depth analysis of the key factors that hinder entrepreneurship of male and female university students,and the features of male and female students' entrepreneurial motivation.吉林省社会科学基金项目(项目编号:2006069

catena-poly[di-μ(2)-chloro(1,10-phenanthroline)cadmium(II)]

The crystal structure of the 1/1 adduct of cadmium dichloride with 1,10-phenanthroline, [CdCl2(C12H8N2)](n), is based on an infinite chain of Cd2Cl2 parallelograms sharing their Cd corners. The chain propagates in a zigzag manner along the c axis of the monoclinic unit cell. The Cd atom and the phenanthroline molecule both lie on special positions of 2 symmetry

Peroxomolybdate(VI)-citrate and -malate complex interconversions by pH-dependence Synthetic, structural and spectroscopic studies

The reaction of potassium molybdate(vi) with biologically relevant ligands, citric and malic acids, in the presence of H2O2 was investigated for the effect of pH variations on the product pattern. That with citric acid led to the formation of the monomeric complex K-4[MoO(O-2)(2)(cit)].4H(2)O (1) in the pH range 7-9, and dimer K-5[MoO(O-2)(2)(Hcit)H(Hcit)(O-2)(2)OMo].6H(2)O (2) (H(4)cit = citric acid) at pH 3-6 through carboxylate-carboxylic acid hydrogen bonding. The relation with the previously identified K-4[MoO3(cit)].2H(2)O (4) and K-4[Mo2O5(Hcit)(2)].4H(2)O (5) were shown. These and other intermediates were shown to react in the pH range 3-6 to give a more stable species 2; the reaction sequence was demonstrated either by the protonation from 1 or the deprotonation of [MoO(O-2)(2)(H(2)cit)](2-)(8). Evidence that 2 exists as a dimer in solution is presented. The reaction with (S)-malic acid afforded Delta-K-2n[MoO(O-2)(2)((S)-Hmal)](n).nH(2)O (3) (H(3)mal = malic acid) that was oxidized further to oxalato molybdate (11) by H2O2. The three complexes 1-3 were characterized by elemental analysis, UV, IR and NMR spectroscopies, in addition to the X-ray structural studies that show citrate and malate being coordinated as bidentate ligands via alpha-alkoxyl and alpha-carboxylate groups. The formation of these complexes is dictated by pH and their thermal stabilities varied with the coordinated hydroxycarboxylate ligands
