An advanced genetic algorithm was used to make an optimization analysis on the solar thermal propulsion system condenser parameters for reducing the mass of system. Considering the sunlight collection efficiency and the mass of condenser as the optimization objective function, a mathematical model of condenser work was established and several related simulation researches were carried out. The simulation results show that the advanced genetic algorithm can be effectively used in the optimization analysis of the sunlight collection efficiency and the condenser mass.

Minchao Liao, Lili Fan
Open Journal of Business and Management (OJBM) , 2014, DOI: 10.4236/ojbm.2014.23028
Abstract: In the background of cut-throat competition in the FMCG industry, work behaviors of the salesman at the forefront of the business play an important role to achieve the marketing objectives. Based on the sales behaviors and related scale development theory, and following the logic of analyzing FMCG sales order work stages first, and then the sales order work contents of each stage, and the work behavior characteristics of sales order of each stage at last, the work behavior of FMCG salesman is discussed in this paper.

自动化学报 , 1997,
Abstract: An unsupervised hypersphere neural network that is used for pattern clustering is presented.Each clustered pattern set is a fuzzy set hypersphere with a corresponding membership function.A pattern class is the combination of the pattern sets.The center and radius of the hypersphere are determined using the fuzzy hypersphere learning algorithm,an expansion contraction process that can learn nonlinear pattern set boundaries in few passed through the data and provides the ability to incorporate new and refine existing pattern sets without retraining.The simulation of clustering demonstrates the superiority of the fuzzy hypersphere clustering neural network.

Abstract: 吸气式冲压推进技术是吸气式太阳能热推进技术的基础。如何设计一种性能理想的进气道是吸气式太阳能热推进技术研究的重点。应用稀薄气体动力学仿真常用的直接数值模拟蒙特卡洛算法对两种常见的进气道结构进行仿真分析,得到两种进气道工况下气体的温度、密度、流量系数和速度等参数的分布,并进行对比。通过比较,选择一种性能较好的构型作为吸气式太阳能热推进系统的进气道,从而为后续系统的设计、计算、分析和优化打下了基础。
Air-breathing scramjet propulsion is the basis of air-breathing solar thermal propulsion technology. How to design an ideal air-inlet is crucial for the propulsion system. By taking advantage of the common method, the DSMC(direct simulation Monte Carlo) on rare-field gas dynamics research, was made to simulate two kinds of air-inlets, which obtained a lot of air parameters such as temperature, density, coefficient of flow and velocity. Then it selected a better air-inlet shape from comparison and treated the shape as a basic air-inlet shape in air breathing solar thermal propulsion system. It lays a foundation for the design, computation, analysis and optimization on the whole system.
Wnt/b-catenin信号通路对靶基因转录的调控
,
中国科学 生命科学 , 2014, DOI: 10.1360/052014-138
Abstract: Wnt/b-catenin信号通路又被称为经典Wnt信号通路,在早期胚胎发育、成体组织稳态维持、干细胞干性调控和肿瘤发生等过程中均发挥重要作用.经典Wnt信号通路的核心信号转导因子b-catenin与核内转录因子TCF/LEF家族成员结合后,通过募集或替换一系列协同作用因子,诱导染色质结构变化,调控Wnt信号靶基因的转录.本文将从Wnt信号靶基因转录调控的基本模式、分子机制、表观遗传学调控和意义等方面,总结近年来有关Wnt信号靶基因转录调控的研究成果,方便读者更好地理解Wnt信号通路靶基因的转录调控.
广东南路地形

地理学报 , 1939, DOI: 10.11821/xb193901002
Abstract: 通称广东南路者,意即指广东西南部,东起阳江,西迄防城与安南接壤处。东西相距约四百公里,沿海分布,南北宽度约百数十公里,雷州半岛与海南岛亦属焉。广东南路地理之研究,从任何方面观察之,均极显明而单纯。以其位于我国最南端,故气候炎热而雨量丰富。物产表现热带性,除谷类外,以甘蔗,落花生蕃薯为最大宗。甘蔗及落花生为制糖及榨油之用。家畜有牛、猪、鷄、鸭。地广人稀,物产过剩,多向外输出,其主要销场为香港、广州、四邑,远至南洋一带。

团结沟斑岩金矿床多源成因的同位素地质学证据

地质与勘探 , 1984,
Abstract: 矿床地质特征团结沟矿床是我国著名的斑岩型金矿床.矿区内主要发育一套侏罗-白垩纪中酸性陆相火山岩及次火山岩.火山活动初期以中酸性熔岩为主,包括玄武安山岩、英安岩等;中期有次火山岩相的花岗闪长斑岩侵入,并带来该区的工业金矿化;火山活动末期以喷发活动为主,并生成各种中酸性火山碎屑岩,包括火山角砾岩、晶屑凝灰岩、凝灰质砂岩等;其底部火山岩中见有含矿斑岩体的角砾.钾氩法测定含矿斑岩体的年龄是100、102、112.6百万年,为燕山期产物.火山岩周围是元古界片岩,更远处往西15公里有混合
最佳现金持有量成本分析模式之错弊分析

财会月刊 , 2011,
Abstract: 最佳现金持有量的成本分析模式来自西方,被广泛引用于我国各种版本的《财务成本管理》教材之中。但笔者发现它是错误的,成本分析模式存在的错误主要表现在以下几个方面:  一、将无关的管理成本纳入计算分析之中企业持有现金产生管理成本,但管理成本属于固定成本,与现金持有量的大小无关,因此计算最佳现金持有量时没有必要将它计算在内,把它排除在外,并不影响最后的结论。现用2010年CPA考试《财务成本管理》教材中P392的例子来说明这一点(见表1,金额单位为“元”,下同):
合并商誉摊销方法管见
宗(教授)
财会月刊 , 2006,
Abstract: 2006年2月15日颁布的《企业会计准则第33号——合并财务报表(以下简称“新准则”)把“合并价差”改成“商誉”,并规定,商誉发生减值的,应当按照经减值测试后的金额列示。减值应如何进行账务处理新准则并无规定,笔者对此谈谈自己的看法。如果母公司对其子公司的长期投资采用简单权益法核算,则合并商誉减值的会计处理采用表摊法;如果母公司对其子公司的长期投资采用复杂权益法,则合并商誉减值的会计处理采用账摊法。
