Statistics is a power.ul tool for.data measur.ment. Statistical techniques pr.per.y planned and executed give meaning to meaningless data. The difficulty some pr.ctitioner. encounter.hinges on the fact that though ther. ar. numer.us statistical methods available for.use in analysis, the extent of their.under.tanding and ease of using these tools for.analysis is limited. This study has twofold pur.ose: fir.tly, liter.tur. on categor.cal data commonly used in r.sear.h was reviewed; next, we reported the results of a survey we designed and executed. Categorical data was collected via questionnaire and analyzed to serve as a backbone of the robustness of categorical data. Several conjectures about the independence of the socio-economic variables and e-commence were tested. Some of the factors influencing patronage of e-commerce were identified. It is clear from the literature that as one’s academic qualification improves, there is an associated improvement in their preference for e-commerce, but the results revealed otherwise. Size of family was found to influence e-commerce. Both income and social status positively affected patronage in e-commerce. Gender also appeared to affect patronage in e-commerce. 62.3% of staff had patronized e-commerce.r.ana;"> This shows that e-commer.e patr.nage was gr.dually incr.asing. It is ther.for. o

Singer.人（1993）的研究表明通过仔细选择一个特异的底物有可能改变一个多步反应的动力学轨迹；pH跳跃能提供一个有效的，依赖于扩散的方法在整个晶体范围内触发一个慢催化事件。在这个例子中，丝氨酸蛋白酶胰蛋白酶在亲核反应残基Ser.95处被p-胍基苯甲酸（GB）酰化。在这个底物很容易形成一个酰基化酶中间物，但进行水解和再生游离酶却很慢。

在解除管制的市场环境中,上游燃料市场和下游电力市场存在博弈关系。从长期来看,上下游市场的博弈关系反映了各市场主体的发展趋势,厘清关系能够为制定合理政策提供科学依据。在无容量约束的理想情况下,博弈关系较为简单,认识较清楚,但当存在发电容量约束,特别是容量约束发挥作用时,博弈关系将变得十分复杂。为此,文中基于建立的上下游市场博弈模型,采用数学分析的方法,以具有低热耗率发电技术的高效率电力集团容量约束为例,对具有不同技术特征电力集团之间及与燃料集团的博弈关系进行了定性分析,并通过仿真方法反复模拟博弈过程,验证了分析结果。研究结果表明,发电容量约束将打破理想情况下上下游联合博弈市场的纯策略均衡状态,形成软约束和硬约束两种不同均衡状态。
