Chapter 1b

对于语言学的研究可以追溯到古希腊时期。

公元前五到四世纪,希腊著名哲学家苏格拉底、伯拉图、亚里斯多德在他们的研究中对语言的研究就站和大地位。

伯拉图的一篇《对话》,《克雷特里斯》(Cratylus)讨论到词为什么具有意义。

克雷特里斯认为:一个对象的名称是由于它的性质而产生的所以语言自然而然地具有意义。

赫莫吉尼斯:反对这种观点,认为名称之所以能指称生物是由于惯例的原因,也就是语言使用者达成的协议。

然后苏格拉底论述两种观点的有缺点。

他说,一个句子分成两部分,名词部分和动词部分。

亚里斯多德是古希腊最著名的哲学家、思想家。

他在《解释篇》、《修辞学》、《诗学》等著作中讨论了有关语言的问题。

他认为:由于形成于惯例,因为名称没有天然产生之理。

语言的词汇只是这些思想的标记。

他进一步讨论名词部分和动词部分,指出名词没有时间成分,而动词有时间成分。

斯多噶派是盛行于公元前四世纪的一批哲学家和逻辑学家。

(他是亚里斯多德的反对者)他们区分了五大词类:名词、动词、连词、冠词和关系代词。

提出“白板说”“自然说”。

亚历山大大帝建立了两个殖民地:埃及亚历山大、土耳其帕加马,亚里斯多德将自己的藏书都赠给了亚历山大,许多学者来此定居从事科学研究成了有名的亚历山大学派、帕加马学派。

辩论的开始围绕:自然界是如何构成的,自然界的运动情况如何反映到人类语言之中?(公元300--146)斯拉克思《语法科学》总结了亚历山大派的语法研究工作,在第一部中进行了语音研究语法部分他认为词汇分8种。

名词、动词、冠词、代词、介词、副词、连词,分词。

文艺复兴前只是对古希腊和拉丁语的研究,14,15 世纪开始将语言学范围扩大。

开始对希伯来语阿拉伯语的研究。

因为《圣经》原文是希伯来语。

古罗马与古希腊来往已久,公元前三世纪罗马帝国征服希腊城之后,希腊科学文化直接影响罗马的发展。

罗马帝国西部拉丁语是官方语言,东部希腊语事官方语言。

希腊的文化科学乘机而入。

著名语言学家瓦罗将语言研究分为三大部分:词源学、形态学、句法学。

流体力学与传热(英文版)chapter1b
the shear stress is proportional to the shear rate du (1.2-3)

dy
(the proportionality constant μ is called the viscosity, unit of μ is kg/(m.s) ) Eq. (1.2-3) is called Newton’s law of viscosity. It is good for Newton’s fluids and laminar flow. Gases and most liquids belong to Newtonian fluids
Chapter 1
1.2 Fluid-flow phenomena
• Ideal fluid
which has zero viscosity. Without friction or resistance when fluid flows through the channel.
• Potential flow
The velocity field
• If the wall is at rest in the reference frame, the velocity of the fluid at the interface is zero, but there’re variations in velocity from point to point in the flowing stream at distances away from the solid . • The velocity field exists in the space occu pied by the fluid.
