We introduce a broader range of channels enhancing growth either by external diffusion of knowledge from technology advanced countries to late-comer countries or by experiential diffusion of knowledge brought about by the interaction between venture capitalists and start-up entrepreneurs.

传统的内生成长理论著重在人力资本及研究发展的重要，我们则进一步将另外两类的知识长成管道纳入现有的理论模型：一是来自技术先进国家对技术落后国家的知识外溢效果，包括衡量以出口及外人投资为管道的技术吸收能力，与国家间技术发展的差异；二是来自创业投资者对新进公司企业家的经验传递效果。

Especially the colossal magnetoresistance manganates La1-xCaxMnO3 , one of interesting materials in our lab, exhibited strongly CAPO at various doping concentrations (x=0, x=0.3 and x=0.58). However, several mechanisms about the generation and detection of CAPO have been proposed and disputed each other.

特别是在本实验室感兴趣的La1-xCaxMnO3庞磁阻材料，在几个掺钙含量x=0、x=0.3、x=0.58，也都呈现明显的同调声子振荡，虽然形成同调声子振荡的机制有几种不同的理论模型，但互相仍有所争议。

The simulation model consists of a sub-wavelength aperture and a metal-coated fiber probe scanning in constant height mode. Influences of the scanning height and the aperture size of the fiber probe on optical field detection are discussed.

选择纳米孔径的隐失场光场和镀金属膜光纤探针建立了近场光探测的理论模型，讨论了探针孔径尺寸、扫描高度等因素对光场探测的影响，以及测量光场与初始光场之间的关系等。

As a nondestructive technique to measure the inner fine structure of the cathode, the ICT has the uniqueadvantage.We discussed the emission mechanism of thermionic cathode, and tried to explain the excellent performance of mixed metal cathode by Richardson formula and Mullers computational model.

4就当前钡钨阴极发射机理的两个主要理论模型作了自己的探讨，并初探了钡钨阴极中钡的供应机制及发射寿命预测的问题，而且用理查逊公式的推导和Muller计算机模拟法解释了混合基钡钨阴极的优良性能。

Theoretical model of N×N dielectric slab star coupler.

The mentioned theoretical models of avoidance condition, tax solution and tradeable permits work under this principle.

所述避免条件的理论模型、税赋方案和可交易的许可都在此原则下工作。

The experimental results agree well with that of the theoretical analysis. The results also show that during the liquid injection, a hollow swirling jet is formed in the shape of an olive with a thin shell.

应用质量守恒定律和动量守恒定律，本文首创性的建立了用于描述旋流喷嘴射流初始阶段所形成的空心旋转射流的运动的理论模型，并采用数值方法进行求解。

Summing up the results of theoretical models and empirical analyses in the thesis, the thesis shows that the increasing liquidity is the primary motivations which drives banks to securitize, and the liquidity enhancement and efficiency improvement are the effects of bank asset securitization. And the gains to securitize bank's assets are from the optimization of bank's capital structure.

概括本文研究得出的理论模型结果和经验分析结果，本文的结论是：银行进行资产证券化的主要动因在于增加流动性；资产证券化为银行带来的效果是流动性提高和效率改善；资产证券化的收益来源于银行利用资产证券化所进行的资本结构优化。

Although many researchers have studied the synthesis of allyl phenyl ether by phase-transfer catalysis, no studies have used it in membrane reactor up to now. The purpose of this paper is to combine the studies of membrane reactor and phase-transfer catalysis. The membrane was used to stabilize the aqueous/organic interface at a fixed position, also the quaternary ammonium ion in the membrane was used as the catalyst to partake in the reaction system directly, and so it can also separate the product and reactants at the same time. A theoretical model is also presented.

中文摘要对於利用相间转移触媒催化技术来合成丙烯基苯基醚的反应，已有不少专家学者研究过，而至今还无在薄膜反应器中进行此反应之研究，本研究则是要结合薄膜反应器与相间转移触媒两者之特性，固定水油两相之界面，并且利用薄膜上的四级铵离子为触媒，直接在反应系统中参与反应，并同时分离产物及反应物，进而推导出相关之理论模型。

According to the classical theoretical model of the conversion of dual economic structure that was introduced by Lewis and completed by John C. H. Fei and Gustav Ranis, if agricultural productivity of labor is not raised correspondingly in the process of industrialization, there will be a time that is short of agricultural products in the country, and it is very possibly to result in food crisis.

根据由刘易斯提出，经过费景汉、拉尼斯等人进一步发展完善而成的二元经济结构转化的经典理论模型，在一个国家工业化过程之中，如果农业劳动生产率没有相应提高，就可能出现一个农产品的短缺时期，而农产品的短缺极有可能导致粮食危机。
