sequence定义？

一、sequence定义？

sequence是一个英语单词，意思是顺序； [数]数列，序列；连续；片断插曲。

释义。

n.

顺序; [数]数列，序列; 连续; 片断插曲。

vt.

使按顺序排列，安排顺序; [生化]确定…的顺序，确定…的化学结构序列。

sequence(序列)是一组有顺序的元素的集合

(严格的说，是对象的集合，但鉴于我们还没有引入“对象”概念，暂时说元素)

序列可以包含一个或多个元素，也可以没有任何元素。

二、什么叫sequence？

Sequence是数据中一个特殊存放等差数列的表，该表受数据库系统控制，任何时候数据库系统都可以根据当前记录数大小加上步长来获取到该表下一条记录应该是多少，这个表没有实际意义，常常用来做主键用。不过各个数据库厂商没有一个统一的标准--各有各的一套对Sequence的定义和操作。

三、java的escape sequence

在Java编程中，有许多概念和语法规则需要开发人员熟练掌握，其中之一是 *java的escape sequence*。在本文中，我们将深入探讨这一概念的含义、用法以及在实际开发中的重要性。

什么是Java的escape sequence？

*Java的escape sequence*是一种特殊的字符序列，以反斜杠（\）开始，后面紧跟一个或多个字符。这些转义序列通常用于表示在普通字符串中难以输入或直接表示的字符，例如换行符或制表符。

在Java中，常见的 *escape sequence* 包括：

• \n - 换行符
• \t - 制表符
• \\ - 反斜杠
• \" - 双引号
• \r - 回车符

为什么需要使用Java的escape sequence？

在编写Java程序时，经常会遇到需要输出特殊字符的情况，例如在字符串中包含引号、换行符等。使用 *escape sequence* 可以帮助开发人员更方便地表示这些特殊字符，使代码更易读和易维护。

举例来说，如果想在字符串中包含双引号，直接输入双引号可能会被编译器误解为字符串的结束。这时可以使用 *\"* 来表示双引号，从而避免这种歧义。

在实际开发中如何使用Java的escape sequence？

以下是一些常见情况下如何使用 *Java的escape sequence*：

1. 在输出语句中插入换行符： System.out.println("第一行\n第二行\n第三行");
2. 在字符串中表示制表符：

         
           System.out.println("列名\t数据1\t数据2\t数据3");
         
       

3. 处理文件路径中的反斜杠：

         
           String filePath = "C:\\Users\\username\\Desktop\\file.txt";
         
       

通过以上示例，我们可以看到 *escape sequence* 的灵活运用可以帮助我们处理各种特殊字符的情况，使代码更加清晰和可读。

总结

在Java编程中，了解和熟练使用 *Java的escape sequence* 是非常重要的。它能帮助我们更好地处理字符串中的特殊字符，避免歧义，并使代码更具可读性和可维护性。

希望本文对您加深理解 *Java的escape sequence* 有所帮助，欢迎在评论中分享您的想法和经验！

五、sequence是什么排序？

等差排序。Sequence是数据中一个特殊存放等差数列的表，该表受数据库系统控制，任何时候数据库系统都可以根据当前记录数大小加上步长来获取到该表下一条记录应该是多少，这个表没有实际意义，常常用来做主键用。不过各个数据库厂商没有一个统一的标准--各有各的一套对Sequence的定义和操作。

Sequence是数据库系统。这个序列一般作为代理主键（因为不会重复），没有其他任何意义。

Sequence是数据库系统的特性，有的数据库实现了Sequence，有的则没有。比如Oracle、DB2、PostgreSQL数据库实现Sequence，MySQL、SQL Server、Sybase等数据库没有Sequence。

定义一个seq_test，最小值为10000，最大值为99999999999999999，从20000开始，增量的步长为1，缓存为20的循环排序Sequence。

六、The Evolution Sequence of Chinese Ancient Calligraphy

Introduction

Chinese calligraphy, a unique art form with a history of thousands of years, has undergone a remarkable evolutionary process. In this article, we will explore the development sequence of Chinese ancient calligraphy, from its origin to its various stages of evolution.

1. Oracle Bone Script 甲骨文

The widely recognized origin of Chinese calligraphy can be traced back to the Oracle Bone Script, which was used during the Shang dynasty. This form of calligraphy was inscribed on animal bones and turtle shells, primarily for divination purposes, and it laid the foundation for the subsequent development of Chinese characters.

2. Seal Script 篆书

The next significant stage in the evolution of Chinese calligraphy was the Seal Script, or Zhuan Shu. This script, characterized by its decorative and angular appearance, was widely used for engraving on seals and officiating documents during the Eastern Zhou dynasty. It represented a shift towards standardized and stylized forms of writing.

3. Clerical Script 隶书

During the Han dynasty, the Clerical Script, also known as Li Shu, emerged as a more cursive and flowing form of calligraphy. Its smooth and elegant strokes, along with its influence from ancient Chinese officials, made it the dominant script for official and formal documents.

4. Regular Script 楷书

The Regular Script, or Kai Shu, simplified the complexity of the previous scripts and became the standardized form of writing during the Wei and Jin dynasties. Its clear and structured strokes, balanced composition, and easy readability led to its widespread adoption and enduring influence on Chinese calligraphy.

5. Running Script 行书

Following the Regular Script, the Running Script, or Xing Shu, emerged during the Eastern Jin dynasty. It represented a more fluid and expressive style, with connected and abbreviated strokes, allowing for greater speed in writing and a more personal touch in calligraphic expression.

6. Cursive Script 草书

Finally, the Cursive Script, or Cao Shu, marked the pinnacle of Chinese calligraphic evolution. It appeared in the later period of the Eastern Jin dynasty and continued to develop through the ages. The Cursive Script's highly abstract and dynamic strokes reflected the calligrapher's emotions and personality, making it a deeply expressive and revered form of calligraphy.

Conclusion

The evolution sequence of Chinese ancient calligraphy, from the Oracle Bone Script to the Cursive Script, showcases the rich history and profound artistic achievements of this traditional art form. Each stage of development represents not only changes in the visual appearance of the characters, but also cultural, social, and aesthetic influences. Understanding this sequence provides valuable insights into the essence and significance of Chinese calligraphy.

Thank you for taking the time to explore the evolution of Chinese ancient calligraphy. By understanding its development sequence, one can gain a deeper appreciation for the diversity and beauty of Chinese calligraphic art, as well as its cultural significance and enduring impact.

a sequence of 的意思是序列，数列，是十分，非常，强调顺序的，还有指的是一系列的事件，动作等。比如a1,a2,a3,a4,a5,a6.etc.就是a sequence of....

a succession of可以翻译成一系列，

“a series of+名词”作主语时，动词用单数，如：A series of pre-recorded tapes has been prepared for language laboratory use.已经为语言实验室准备了一系列预录的磁带。

补充：（1）a sequence of：一系列的；一连串；一个…的序列

例如：

In a sentence a sequence of words becomes more than just a list.

在一个句子中单词的次序不仅仅只是一个表。

Suprasemental features: Distinctive features can also be found over asequence of two or more phonemic segments.

在两个或者更多的音位切分序列层面上同样可以找到一些识别性特征。

（2）a series of：一系列的；一连串的

例如：

Boom! Boom! Boom! A series of explosions shook the valley.

轰!轰!轰! 一连串爆破声震撼山谷。

The challenger delivered a series of punches to the champion.
