科技英語閱讀常考詞彙

In all cases, the diffusion of gas molecules in ice Ih was found to be much higher than the diffusion of water through ice. The self-diffusion coefficient of ice is known to be highly sensitive to temperature, with values increasing from 10-16 to 10-14 m2/s as the temperature is increased between 233 and 273 K.40 At lower temperatures, the self-diffusion coefficient was found to be even lower, between 10-20 and 10-18 m2/s at temperatures between 140 and 170 K.41-43

l 翻譯：在所有的情況下，氣體分子在Ih型冰中的擴散遠遠高于水分子在冰中的擴散。冰的自擴散系數對溫度十分敏感，當溫度從233增加至273K，擴散系數從10-16增加到10-14平方米/秒。在較低溫度下,自擴散系數也更低, 如當溫度處于140 - 170 K間時，擴散系數介于10 - 20至10 - 18 m2/s間。

(1) diffusion：擴散；散布；彌漫；漫射

l 詞源分析：詞根詞綴：dif-分離,分開 -fus-熔,注 -ion名詞詞尾。fus-fus可用詞根flu-流動來輔助記憶，流、注入、熔三個動詞的畫面感其實還是很像的。dif-=dis- 非，相反，分開三個基本意思，都是來自單詞two，t-d，wo-I，是非、正反、分開都是二心，表示離開、分開之意。confuse 混淆；effuse湧出流出；fuse融化；futile徒勞的（注入到一個洞裡面的，也即滲漏到洞裡面，全漏了的，徒勞的）infuse注入；interfuse 混入、混合（把一個東西從中間熔進去、注進去）；profuse揮霍的，浪費的，充足的；

(2) coefficient 系數

l 詞源分析：efficient：效率高的，(人)有能力的。詞根詞綴： ef- (= ex- )出 -fic- 做 , 作 -i- -ent 形容詞詞尾。co-一起，來自come，來，一起！所以本身也包含強調的含義。為什麼十分高效的可以表示系數呢？最初是用在數學中，如x2中的2就是系數，那麼這就是十分高效的，一下子使得x翻了好多倍。後來才用來表示物理系數。1. (mathematics 數) a number which is placed before another quantity and which multiplies it, for example 3 in the quantity 3x• 系數2. (physics 物) a number that measures a particular property (= characteristic) of a substance• (測定物質某種特性的)系數: »the coefficient of friction 摩擦系數

(3) sensitive 敏感的

l 詞源分析：sense：感官，感覺，意義，含義，理解力，判斷力。來自古法語 sens, 感覺，知覺，理解，五種感官的功能，來自拉丁語 sensus, 感覺的，知覺的， 感知的，過去分詞格于 sentire, 感覺，感知，知曉，來自 PIE * sent, 感覺，可能來自 PIE * sent, 走，離開，送出，詞源同 send. 其邏輯關系可能為摸着石頭過河，根據感覺找路。引申諸相 關詞義。

(4) increase

(5) by：靠近，按照

l 來自 PIE * ambhi, 在周圍的。 bhi, 同前綴 bi-, 兩。詞源同 two。該詞的英語詞源請訪問趣詞詞源英文版：by 詞源，by 含義。by的所有的含義都和在…周圍、靠近…；例如by有憑借的意思，就是靠近走攏，然後才可以憑借；House prices went up by 10%. by 10%就是靠近10%的意思。

(6) even

◙ adv. 1. used to emphasize sth unexpected or surprising• (強調出乎意料)甚至,連,即使: »He never even opened the letter (= so he certainly didn't read it).2. used when you are comparing things, to make the comparison stronger• (用以加強比較)甚至更,愈加,還: »She's even more intelligent than her sister. 她甚至比她姐姐還聰明。 3. used to introduce a more exact description of sb / sth• (引出更精确的說法)甚至可以說,其實,實際上: »It's an unattractive building, ugly even. 這棟建築毫不美觀,甚至可以說難看。
