2.(4) The model of competence substitution in the evolution of DCCC—Conditioned emergence model could be used in management of competence substitution process. It includes three stages: conditions for competence substitution,creating conditions states far from existing equilibrium,and managing feedback.

设计特异性细小病毒引物扩增VP2基因的两个片段,并进行测序,分析结果表明,该毒株是在CPV-2a的基础上其VP2的第297位氨基酸发生A→S突变,第300位氨基酸发生G→S突变,第301位氨基酸发生T→A突变。
4.In order to estimate an appropriate housing production function and to estimate related elasticity of substitution between land and capital, we estimate two traditional production functions, namely constant elasticity of substitution (CES) and variable elasticity of substitution (VES), by applying a firm-level data set in Taiwan from 1981 to 1992.
为正确的查找适当的住宅生产函数，以及其中对应的土地与资本之间的替代弹性，本文分别对常规的固定替代弹性模型(CES)与可变替代弹性模型(VES)加以估计。
5.The aromatic electrophilic substitution reaction was studied using NMR for the first time.On the base of substituents effects on the benzene,the orientation effect and reactivity was analysised quantitatively.This method may mostly predict the aromatic electrophilic substitution reaction.
首次采用NMR研究芳基亲电取代反应.依据取代基对苯的影响，定量分析了定位效应和反应活性.此法对芳基亲电取代反应有一定的预见性.
6.The substitution of one metrical unit for another, especially the substitution of two short syllables for one long syllable in quantitative verse.
长音节的拆分或替换一个韵律元素替代另一个，尤指在数量韵文中用两个短音节替代一个长音节
7.By the accurate measuring to the voltage across the standard resistor,it can be known whether the DC substitution power of each range of the 1805B RF control unit meets our demands. Finally,the range of DC voltage corresponding to DC substitution power is provided.
通过对标准电阻两端直流电压的准确测量,就可判断1805B在各档的直流替代功率是否满足要求,本文最后给出了直流替代功率所对应的直流电压范围。
