"o"在古希腊字中是代表什么???
上次一新加坡朋友向我打听甲骨文的资料,说他女儿学习汉语之用!
突然想到我们国内学习英文的思维角度.跟这完全不一样. ...
Οο > micron
Omicron (uppercase Ο, lowercase ο, literally "small o": Όμικρον, o mikron, micron meaning 'small' in contrast to omega) is the 15th letter of the Greek alphabet. In the system of Greek numerals it has a value of 70. It is rarely used in mathematics because it is indistinguishable from the Latin letter O and easily confused with the digit 0. This letter is derived from the Phoenician letter Ayin. In modern Greek, Omicron represents the sound IPA: [ɔ]. Letters that arose from omicron include Roman O and Cyrillic O.
In Unicode the capital letter is codepoint U+039F and the lowercase is U+03BF.
The upper-case letter of omicron (O) was originally used as a symbol for Big O notation, representing the asymptotic rate of growth of a function in mathematics.
Omicron(大寫Ο,小寫ο,中文音譯:奧密克戎),是第十五個希臘字母。Omicron 字面上的意思是「小的 O」(o mikron),以便與ω「o mega,大 O」區別。
它在希臘數字中代表70。這個字母由於與拉丁字母 O 和數字 0 相似,人們大多不會使用這個字母作符號用途。
大寫Ο用於: * 大O符號
