113 年國立清華大學動力機械工程學系碩士班丙組《科技英文》考古題與詳解

Question 1

Carbon dioxide is a of carbon and oxygen. (A) compound (B) compounds (C) compounding (D) compound in (E) compounded

Accepted Answer

本題考查單數與複數名詞的用法，以及名詞與介詞的搭配。
句子的主語是 "Carbon dioxide"，謂語動詞是 "is"，後面需要一個名詞來解釋 "Carbon dioxide" 是什麼。
選項 (A) compound 是單數名詞，意為「化合物」，符合語意。

Question 2

The new machine the engineers attracted many possible sponsors. (A) production (B) produced (C) produced by (D) producing (E) producing by

Accepted Answer

核心觀念：分詞片語修飾名詞 句子主幹為： The new machine attracted many possible sponsors. 主詞是 The new machine，動詞是 attracted，受詞是 many possible sponsors。 空格位於名詞 machine 後方，功能是修飾這部機器，因此需要填入分詞片語： produced by the engineers 其完整形式可還原為關係子句： The new machine which was produced by the engineers attracted many possible sponsors. 其中 which was produced by the engineers 修飾 machine。省略關係代名詞與 be 動詞後，變成過去分詞片語 produced by the engineers。 解題方法 判斷名詞後的分詞形式，先確認名詞與動作之間是主動還是被動關係： - 機器是「被工程師製造」的，屬於被動關係。 - 被動語態使用過去分詞 $p.p.$。 - 若要表示「由某人……」，搭配介系詞 by。 因此： $$ 	ext{machine} + 	ext{produced by the engineers} $$ 意思是「由工程師製造的新機器」。 完整句意為： 由工程師製造的新機器吸引了許多潛在贊助者。 選項分析 (A) production production 是名詞，意為「生產、製造」。填入後為： The new machine production the engineers attracted many possible sponsors. 名詞 production 無法直接接在 machine 後面形成合理的修飾結構，且 the engineers 也缺乏適當的句法功能，因此錯誤。 (B) produced produced 是過去分詞，表示被動或完成的概念，但此處若單獨使用： The new machine produced the engineers attracted many possible sponsors.

這裡的 "novel functional devices" (新穎的功能設備) 是前面的主語 "unique aspects of nano-spaces" 所能實現的對象。
空格處需要連接 "novel functional devices" 和 "difficult to obtain using conventional bulk spaces"。
這是一個修飾語從句，用來描述 "novel functional devices"。

選項分析：
(A) are - 如果是 "novel functional devices are difficult to obtain..."，這是一個完整的句子，但前面已經有 "can be used to realize"。

Question 32

32. What is equal to 1000 nm? (A) 10^3 m (B) 10^-6 m (C) 10^9 m (D) 10^-12 m (E) 10^-15 m

Accepted Answer

本題考查長度單位的換算。 奈米 (nm) 是長度單位，1 奈米等於 $10^{-9}$ 公尺 (m)。 所以，1000 nm 等於 $1000 	imes 10^{-9}$ m。 $1000 = 10^3$。

Question 33

33. What is the volume of the cubic with 100 nm width, 100 nm height, and 100 nm length? (A) 10^-6 liter (B) 10^-9 liter (C) 10^-12 liter (D) 10^-15 liter (E) 10^-18 liter

Accepted Answer

本題考查體積計算與單位換算。
立方體的體積計算公式為：體積 = 長 × 寬 × 高。
題目給定的尺寸是：寬 100 nm，高 100 nm，長 100 nm。
體積 $= 100 \text{ nm} \times 100 \text{ nm} \times 100 \text{ nm} = (100)^3 \text{ nm}^3 = (10^2)^3 \text{ nm}^3 = 10^6 \text{ nm}^3$ 。

接下來需要將體積單位從 $nm^3$ 轉換為公升 (liter)。
我們知道：
1 m = $10^9$ nm
所以，1 $m^3$ = $(10^9 \text{ nm})^3 = 10^{27} \text{ nm}^3$ 。
同時，1 m $^3$ = 1000 liter。

Question 34

34. When 1 nN is applied to the area with 1000 nm width and 1000 nm height, what is the pressure value? (A) 1 mPa (B) 1 Pa (C) 1 hPa (D) 1 kPa (E) 1 MPa

Accepted Answer

本題考查壓力計算與單位換算。
壓力 (Pressure) 的定義是壓力 $P = \frac{F}{A}$ ，其中 $F$ 是力 (force)， $A$ 是面積 (area)。
題目給定的力 $F = 1 \text{ nN}$ 。
1 nN (nanoNewton) $= 1 \times 10^{-9}$ N。
面積 $A$ 是由寬 1000 nm 和高 1000 nm 組成的矩形面積。
$A = \text{width} \times \text{height} = 1000 \text{ nm} \times 1000 \text{ nm} = (1000)^2 \text{ nm}^2$ 。
$1000 \text{ nm} = 1000 \times 10^{-9} \text{ m} = 10^{-6} \text{ m}$ (根據上一題的換算)。

Question 35

35. What parameters were measured and controlled? (A) Voltage was measured with controlling pressure. (B) Current was measured with controlling pressure. (C) Voltage and current were measured with controlling pressure. (D) Pressure was measured with controlling voltage and current. (E) All of the voltage, current, and pressure were controlled and measured.

Accepted Answer

本題需要根據圖一的說明和圖表來判斷。
圖一的標題是 "Figure 1. Measured voltage and current value as functions of applied pressure..."。
圖表的橫軸是 "Applied pressure [MPa]"，縱軸是 "Voltage [V]" 和 "Current [pA]"。
圖表的說明文字提到 "...with controlling the pressure pump."。
這表示壓力是被控制的變量 (controlled parameter)，而電壓和電流是被測量的變量 (measured parameters)。

選項分析：
(A) Voltage was measured with controlling pressure. - 部分正確，電壓被測量，壓力被控制。

Question 36

36. Why current and voltage values on unmodified surface were increased with increasing the applied pressure? (A) Because the voltage increased the current. (B) Because the current increased the voltage. (C) Because the current and voltage induced the pressure. (D) Because the pressure induced the flow rate and flow rate induced the current and voltage. (E) Not mentioned.

Accepted Answer

本題需要根據圖一的說明文字來回答。
圖表的說明文字提到：
"The current and voltage were proportional to the applied pressure, which indicates that the flow rate inside the channels was increased according to the increase of applied pressures. Then, the increase of flow rate contributed to the increase of current and voltage."

Question 37

37. What is the relationship between the electric signal and surface charge? (A) The electric signal with a sign opposite to the surface charge was obtained. (B) The electric signal with a sign similar to the surface charge was obtained. (C) The electric signal was obtained by neutral surface charge. (D) The electric signal was obtained by surface charge only on the unmodified surface. (E) No relationship between the electric signal and surface charge.

Accepted Answer

本題需要根據圖一的說明文字來回答。 說明文字提到： "A positively charged surface was obtained by modification with amino group, which resulted in surface amino groups yielding negative current and voltage values. Therefore, information corresponding to the surface charge state was reflected by the electric signals obtained." 分析這段文字： - "A positively charged surface was obtained by modification with amino group" - 氨基修飾後得到正電荷表面。 - "...which resulted in surface amino groups yielding negative current and voltage values." - 氨基修飾後的表面產生負的電流和電壓值。

Question 38

38. Why did the fluorescent signal of the microchannel become stable after 4 minutes? (A) Because water was introduced to the microchannel after 4 minutes. (B) Because the introduced fluorescent solution was diluted by water in the microchannel. (C) Because water in the microchannel was replaced by the introduced fluorescent solution. (D) Because the fluorescent solution in the microchannel was removed from the nanochannel. (E) Not mentioned.

Accepted Answer

本題需要根據圖二的說明文字來回答。 圖二的說明文字提到： "The replacement of the liquid in the nanochannel was finished in approximately 1 minute because the fluorescent signal was saturated after 1 minute. Then, the fluorescent solution was continuously supplied to the microchannel, and the replacement of liquids in the microchannel was finished in approximately 4 minutes." 這段話解釋了為什麼 microchannel 的液體更換需要 4 分鐘。 "replacement of liquids in the microchannel was finished in approximately 4 minutes." 這意味著在 4 分鐘時，微通道中的液體更換完成。

Question 39

39. Choose the incorrect answer about the data in Figure 2. (A) The fluorescent solution was introduced from the microchannel to the nanochannel. (B) It took approximately 4 minutes to replace the liquid in the microchannel because the fluorescent signal was saturated after 4 minutes. (C) The size of the microchannel was much larger than the nanochannel. Therefore, the fluorescent signals of the microchannel were higher. (D) To replace the 20 pL volume in the microchannel, 20 pL of fluorescent solution was introduced with 5 pL/min for 4 minutes. (E) Finally, water in the microchannel and nanochannels was replaced with a fluorescent solution.

Accepted Answer

本題要求找出關於圖二數據的錯誤陳述。需要仔細閱讀圖二的說明文字和圖表。 圖二說明文字提到： "The replacement of the liquid in the nanochannel was finished in approximately 1 minute because the fluorescent signal was saturated after 1 minute. Then, the fluorescent solution was continuously supplied to the microchannel, and the replacement of liquids in the microchannel was finished in approximately 4 minutes." "The signal intensity of the microchannel was much higher than that of the nanochannel due to the difference in the channel sizes." "The replacement time was reasonable because the flow rate of the system was 5 pL/min and the volume of the microchannel was 20 pL." "From these results, liquid replacement in the microchannel using the nanochannel was successfully achieved." 分析各選項： (A) The fluorescent solution was introduced from the microchannel to the nanochannel. - 圖二的圖例顯示 "Microchannel" 和 "Nanochannel (upstream)"。 - 說明文字提到 "liquid replacement from water to a fluorescent solution using the structure of nanochannel(upstream)-microchannel." - 這意味著螢光溶液是從上游（nanochannel）進入，然後流向微通道（microchannel）。 - 因此，螢光溶液是從 nanochannel 流向 microchannel，而不是反過來。 - 這個陳述是錯誤的。 (B) It took approximately 4 minutes to replace the liquid in the microcha…
