英专综合教程6册课文翻译及课后答案Answer to unit 5

IV. Chinese Translation of Paragraphs引言中文译文本文“为迷信辩解一二”最初发表在1978年11月20日的《新闻周刊》上。

为了分析迷信这个复杂的话题,戴维斯将其作了分类,然后详细探讨了为何有人会相信法术和机缘。

尽管人们对他划分的四类迷信现象并不陌生,但是很少有人花费心思进行界定。

戴维斯理性地分析了许多人认为是个非理性的话题,对人性提出了一些非常有趣的看法。

1. 在我们当代有关“非理性复兴”的严肃讨论中,迷信并未对理性和科学形成严重挑战。

超心理学、不明飞行物、神奇治疗、超脱禅定法以及所有瞬间彻悟方式都遭人谴责,但是人们对迷信却只有一声哀叹。

难道这是因为我们当中许多人依然受制于它吗?虽然我们不公开承认。

2. 很少有人承认自己迷信,因为那意味着幼稚或愚昧。

但我生活在一个很大的大学里,发现在那些无疑是头脑理性、满腹经纶的学者中间,迷信仍以四种方式大行其道,香火旺盛。

3. 你不知道迷信有四种存在的方式吗?神学家使我们确信它们确实存在。

他们称第一种方式为镇邪压魔,如切忌在梯子下面行走等。

我看到一位知识渊博的人类学教授不小心弄撒了盐后,撮了点盐撒向自己的左肩膀后方。

当我问起他缘故时,他眼睛一眨,回答说那是“用来击中恶魔的眼睛。

”我没有继续问他有关恶魔的迷信,但我留意到在我问他之前,他脸上没有笑容。

4. 第二种是占卜,即求神问卦。

我认识的另一位渊博的教授对抛硬币解决问题(这是对命运之神谦卑的请求方式)嗤之以鼻,但有一回他却认真地告诉我,他通过拜读《易经》解决了一件本校的事务。

为什么不呢?这块大陆上有成千上万的人求助于《易经》,而他们普遍的知识水平很高,似乎不至于盲从迷信。

几乎如此,但并非完全如此。

令理性主义者难堪的,《易经》往往会给出绝佳的忠告。

5. 第三种是盲目崇拜,大学里面这种情况司空见惯,举不胜举。

你如果在大教室里当过监考,就会知道在课桌上放护符、幸运币等其他祈运物件的考生有多少。

5-4 A lump of copper having a mass of 10(kg) at a temperature of 540(℃) is dropped into a well-insulated bucket containing 100(kg) of water at a temperature of 21.1(℃). If the specific heats of copper and water are 0.095 and 1.000, respectively, calculate the resulting changes in entropy of the water and copper, and calculate the total entropy change resulting from the process.
5-5. What is the thermal efficiency in thermodynamics? Answer: The thermal efficiency refers to the ratio of work obtained to the heat absorbed.
5-6. Please indicate in which condition that the thermal efficiency can approach to 1 or 0? Answer: The only conditions under which the efficiency of a heat engine can approach unity are those for which T1 approaches infinity or T2 approaches zero.
Solution a. Heated by the saturated steam is at 0.7 MPa 1). The entropy change of water: Δ S1 = 10(S65.6 – S 15.6) =10(0.900-0.233) =6.677 kJ/K
2). From heat balance, the steam needed is: ms = 10(65.6-15.6) 4.186/(Hv - HL) = 500 (4.186) / (2762 – 697) = 1.014 kg The entropy change of saturated steam at 0.7 MPa: Δ S2 = 1.014 (SL – Sv) = 1.014 (1.992 - 6.705)= 4.784kJ/K 3).Δ Stotal =Δ S2+Δ S1 =- 4.784+ 6.677= 1.893 kJ/K
Solution Because the amount of heated and heating air are the same, and heat losses are negligible, assuming the Cp is a constant value in this problem, then the difference of temperature for both air must be the same. 93 – 21 = 180 – t’2 , t’2 = 108℃
parallel countercurrent 1) 21℃(t1) 93℃ (t2) 2) 93℃ (t2) 21℃ (t1) 180℃(t’1) 108℃(t’2) 180℃(t’1) 108℃(t’2) Change in entropy also is the same, no matter whether it is parallel or countercurrent flow in the exchanger.
5-5 A heat exchanger is to be constructed in which air (assume Cp = 7/2 R) is to be heated from 21.1 to 93.3(℃) by another stream of air, originally at 182.2(℃). Equal amounts of heated air and heating air are to be used. Assume that heat losses from the exchanger are negligible. a. Calculate the entropy changes of the heated air and the heating air for both parallel and countercurrent flow in the exchanger. b. What is the total entropy change in each case? c. Repeat parts a and b for countercurrent flow if the heating air enters at 108(℃).
5-6 Calculate the entropy changes for the heated water and the heating material, and the total entropy changes, when 10(kg) of water is heated from 15.6 to 65.6(℃):
5-7. How do you increase the thermal efficiency of actual heat engines? Answer: A significant increase in the efficiencies of actual heat engines can be made by increasing the temperature T1 at which heat is absorbed by the engine.
5-3. Please indicate which cycle is the Carnot refrigeration cycle from Fig. 5-3. Answer: A D C B A
5-4. What is the Carnot’s theorem? Answer: The Carnot’s theorem is that the efficiency of converting heat into work in a reversible heat engine must depend not upon the medium employed to run the engine, but only upon the temperature levels θ1 and θ2.
a. Change in entropy of heating air(one mole): ΔS1 = ∫dQ/T = ∫Cp(dT/T) = 7/2(8.314)ln(381.15/453.15) = -5.035 J/K Change in entropy of heated air(one mole): ΔS2 = ∫dQ/T = ∫Cp(dT/T) = 7/2(8.314)ln(366.15/294.15) = 6.371 J/K
b. Total: ΔS = 6.371 – 5.035 = 1.336 J/K c. If heating air entered at 108℃ for countercurrent flow and the exchanger were infinitely large, then the temperature of heating air in the exit would be 35.8℃, for the difference of the temperature of the heating air is identical with that of the heated air
5-1. What is the restriction on the direction of energy transformation? Answer: The second law, which can be described by many general statements, is the restriction on the direction of energy transformation.
Change in entropy of heating air(one mole): ΔS1 = ∫dQ/T = ∫Cp(dT/T) = 7/2(8.314)ln(308.98/ 381.15) = -6.111 J/K Change in entropy of heated air(one mole): ΔS2 = ∫dQ/T = ∫Cp(dT/T) = 7/2(8.314)ln(366.15/294.15) = 6.371 J/K Total: ΔS = 6.371 – 6.111 = 0.26 J/K
5-2. What are the two statements of the second law of thermodynamics? Answer: 1. No apparatus can operate in such a way that its only effect (in system and surroundings) is to convert heat absorbed by a system completely into work. 2. Any process which consists solely(单独) in the transfer of heat from one temperature to a higher one is impossible.
Solution From heat balance: 0.095(10)(540-t2) = 1(100)(t2 – 21), t2 = 25.88℃ Change in entropy of copper: by Eq.(5-28), ΔS =∫dQ/T =∫CpdT/T = 0.095(10)ln(298.15/813.15) = - 0.9507 kJ/K
