tap, tape, taper

[ex]
The tape seems never taper off after winding it on the tap for tens of rounds.


//=== tap
 n. 水龍頭 (tap water 就是 自來水)
 v. 輕拍,輕碰 (輕壓平板電腦的螢幕 to tap the screen of the tablet)

Tap, Double Tap, and Press and Hold on a tablet to turn it off.



//=== tape 
n. 膠帶, 錄音帶, 
casette tape recorder 卡帶錄音機

//=== taper
taper 的起源是指 蠟燭 (wax candle) , 蠟燭燃燒漸漸失去光亮 到最後完全變暗;
taper 後來就用來指 逐步消減, 常與副詞 off 連在一起用.

生命的過程大致與蠟燭類似吧, 
It seemed all of a sudden to the public that 
the famous doctor and toxicologist died a few days ago. 
In fact, he got chronical kidney disease and 
kept fighting for decades but finally tapered off. 
However, he did light and enlighten many others' life. 

逐步戒除抗焦慮/抗憂鬱藥物
 to taper off anti-anxiety and anti-depressant drugs

颱風正逐步遠離
 The storm is beginning to taper off. 

"平均來講" 質數間的間隔是越來越大 或者說越來越稀疏 (taper off)
... mathematicians have understood how the primes taper off "on average": Among large numbers, the "expected gap" between prime numbers is approximately 2.3 times the number of digits; so, for example, among 100-digit numbers, the expected gap between primes is about 230 ...

rabies -- 狂犬病的英文

狂犬病的英文, 直接從字面上來翻就是 mad dog disease.
上網搜尋發現 rabies /r 'e: bi:z/ 這個單字
http://en.wikipedia.org/wiki/Rabies
應該與 rabbit /r 'ae bit/ 無關

狂犬病發生在動物身上叫 rabies,
發生在人身上則叫 hydrophobia (恐水症)
? http://zoonosesonline.org/rabies.html

//=== prophylaxis /pr.f.l 'ae ksis/ 預防性措施/處置/注射/投藥 http://www.thefreedictionary.com/prophylaxis

狂犬病是病毒引發的疾病 而且是人畜共通(zoonotic),
病毒侵入後 經過一段時間的潛伏期 incubation period (數天~數年?),
一旦病毒侵入中樞神經系統(central nervous system) 開始發病後
致死率幾乎是百分百 (that's why it's called a fatal disease).

所以 一旦遭遇動物咬襲 或是 傷口沾染帶有病毒的唾液,
就必須立即進行 post-exposure prophylaxis 疫苗(vaccine)注射
而第一線醫護人員也應定期接種疫苗 (pre-exposure?) prophylaxis

oblivion and taper

債券天王 B. Gross 在六月份的Investment Outlook 說了一句話
" Kodak, Sears, Barnes & Noble, AOL and countless others have been competed to near oblivion by advancing technology, more focused management, or evolving business models ... "

'competed to near oblivion' 頗有 吳宮花草埋幽俓 晉代衣冠成古丘的味道.
多少昔日的千元股王, 如今都已 '隱沒' (oblivion) 於股海中, 風華難再現.

關於 QE 逐步退場 (taper), 債券天王最近連續發聲 :

"... I don’t think today’s report says anything about tapering at all with unemployment going higher and metrics in terms of  the work week and wages being very dour ... "
[Bloomberg News 2013.06.07]

"...  Fed Will Taper Later This Year, But Not for Obvious Reasons ...

... Lower deficits in Washington mean the Treasury will issue less debt, which could create a shortage of Treasury securities if the Fed continues QE at its current pace. ...

... if the Fed owns all the Treasuries, then there is no market for the bonds. So I think at some point they’d taper if only to permit the rest of us to have a few. ... ”
 [Yahoo Finance 2013.06.10]

人潮錢潮 股海翻騰
萬般拉抬 只為出貨
在一片喧囂中
  安安靜靜 一步一步地 
將一種紙張換成另一種紙張
將一種帳戶的數字換成另一種帳戶的數字

In the sea of capital, many victims are flushed to oblivion under the tide of billions of money.
Tycoons taper their input silently and transform output to  another ocean ...
