The Fourth method: Definition a dictionary will give you two different definitions of the word definition: ( \a statement of what a thing is\and(2)a\a statement or explanation of what a word or phrase means or has meant. \ In the strict sense a definition as we shall use the word here is not of a thing. but of a word or of a process The process of making a definition is not, however, a mere game of words. It is clear that we cannot make a usefu

Almost all research papers are expositions. The word exposition quite literally means to set forth a subject. It appeals to the understanding and it is the most common kind of writing, for it is applicable to any task that challenges the understanding--the definition of a word the way to a street address the structure of a plant, the mechanism of a watch, the cause of a historical event the meaning of a philosophy

一、名词解释(6题共30分,每题5分) (1).塑性:外力作用下,材料发生不可逆的永久性变形而不破坏的能力 (2).刚度:外应力作用下材料抵抗弹性变形能力。 (3).抗蠕变性:材料在恒定应力(或恒定载荷)作用下抵抗变形的能力

Surface quality is another aspect of machining accuracy. It consists of the surface finish and the physic mechanical state of the surface layer. It affects the proper functioning and service life of the parts Surface Finish Machining accuracy is expressed quantitatively in machining error. Surface finish is expressed quantitatively in surface roughness. The surface roughness on a machined workpiece surface is caused primarily by the geometrical factors(cutting tool geometry and cutting

不确定性分析 一、项目投资决策中收益与风险的权衡 收益 风险 投资 目标 二、主要的不确定性分析方法 盈亏平衡分析:确定盈利与亏损的临界点 一敏感性分析:分析不确定因素可能导致的后果 一概率分析:对项目风险作直观的定量判断

The manufacturing(or production) process of a factory, in a broad sense, is the sum total of separate processes involved in the conversion of sum total raw materials or semi-finished products into final as far as products. AS far as a factory is concerned, its blank products can be blanks, finished parts
