什么是alpha测试

Α (ALPHA)

Alpha is the first and foremost letter of the Greek alphabet. In the classification of Greek numerals or numbers, it constitutes a value of 1.

Alpha是希腊字母的第一个也是最重要的字母 。在希腊数字或希腊数字的分类中，它的值为1。

Letters that taken place and occurred from alpha comprise the Latin A and the Cyrillic letter А.

从alpha发生和出现的字母包括拉丁字母A和西里尔字母А。

In English, the noun "alpha" is used as a synonym for "beginning", or "first" (in an order of sequence), revealing its Greek roots.

在英语中，名词“ alpha”被用作“ beginning”或“ first”(按顺序的顺序)的同义词，以揭示其希腊语根源。

In Ancient Greek, alpha was articulated [a] and could be either phonemically long ([aː]) or short ([a]).

在古希腊语中，alpha的发音是[a]，可以是语音上的长([aː])或短的([a])。

数学与科学 (Mathematics and Science)

The letter alpha corresponds to a variety of concepts in physics and chemistry, consisting of:
字母alpha对应于物理和化学中的各种概念，包括：
1. Alpha radiation
2. Angular acceleration
3. Alpha particles
4. Alpha carbon
5. Strength of electromagnetic interaction (as Fine-structure constant)
Alpha also corresponds to the thermal expansion coefficient of a compound in physical chemistry.
Alpha还对应于物理化学中化合物的热膨胀系数。
It is also normally used in mathematics in algebraic solutions signifying quantities such as angles.
它也通常用于数学中的代数解，表示诸如角之类的量。
Also, in mathematics, the letter alpha is used to refer to the area underneath a normal curve in statistics to represent the significance level when proving null and alternative hypotheses.
同样，在数学中，字母α用于表示统计中正常曲线下方的区域，以表示证明零假设和替代假设时的显着性水平。
In zoology, it is used to name the leading and governing creature in a wolf or dog pack.
在动物学中，它用来命名狼群或狗群中的领导和统治生物。
In aerodynamics, the letter is used as a symbol for the angle of attack of an aircraft and the word "alpha" is used as a synonym for this property.
在空气动力学中，该字母用作飞机迎角的符号，而单词“ alpha”用作该属性的同义词。

The proportionality operator "∝" (in Unicode: U+221D) is now and then taken false for alpha.

比例运算符“ ∝” (在Unicode中为U + 221D)现在对于alpha而言为假。

The uppercase letter alpha is not commonly used as a symbol for the reason that it is inclined to be provided indistinguishably to the uppercase Latin A.

大写字母alpha不常用作为符号，因为它倾向于与大写拉丁字母A区别不大。

国际语音字母 (International Phonetic Alphabet)

In the International Phonetic Alphabet, the letter ɑ, which appears similar to the lower-case alpha, corresponds to the open back unrounded vowel.
在国际音标，信ɑ，其显示类似于小写字母，对应于开后不圆唇元音。

The New Testament has God speaking out himself to be the "Alpha and Omega, the beginning and the end, the first and the last." (Revelation 22:13, KJV). Because of this symbolism, the characters ⍺ and ⍵ signify the left and right arguments in the APL programming language.
在《新约》中，上帝大声疾呼自己是“阿尔法与欧米茄，开始与结束，第一与最后”。 (启示录22:13，KJV)。由于这种象征意义，字符⍺和⍵表示APL编程语言中的左右参数。

语言 (Language)
