介绍一种高性能彩色工业监视器的设计方法，重点叙述了系统构成及图形、字符单元的工作原理。
The colour industrial monitor with high performance is introduced in this paper. The emphases are put on the system composition and the operation principle of the graph unit and the character unit.
这个字符指定为十六进制形式的一个或两个UTF - 16编码单元。
The character is specified as one or two UTF-16 code units in hexadecimal notation.
可以使用一个或多个各自编码的代码单元来表示字符。
A character can be represented using one or more of the code units of a respective encoding.
使用CODEUNITS16或CODEUNITS32计算代码单元得到的结果是相同的，除非使用了增补字符和代理对。
Counting code units using either CODEUNITS16 or CODEUNITS32 gives the same answer, unless supplementary characters or a surrogate pair is involved.
这种编码概念被称为UCS - 4；四个八位元用来表示指定组、平面、行和单元的每个字符。
This coding concept is called UCS-4; four octets of bits are used to represent each character specifying the group, plane, row and cell.
考虑表1中对此字符的不同编码，您会发现不同代码单元中的不同编码的十六进制表示及其长度都有所不同。
Now consider the different encodings for this character from Table 1, and you can see that the hexadecimal representation of different encodings and their length in different code units are diffrent.
像所有ucs平面那样，包含了256行，其中每行包含256个单元，字符仅仅按照BMP中的行和单元的八位元在单元中被编码。
This BMP, like all UCS planes, contains 256 rows each of 256 cells, and a character is coded at a cell by just the row and cell octets in the BMP.
可以将字符定义为一个信息单元，对应于书面语言的一个原子单元。
A character can be defined as a unit of information that corresponds to an atomic unit in a written language.
处理文本文件通常包括读取信息单元(通常叫做字符或行)，然后对刚读取的单元执行适当操作。
Processing a text file often consists of sequentially reading a unit of information (typically either a character or a line) and doing something in response to the unit you've just read.
从上面到达单元格相当于将左面的字符从S2加入S2'，跳过上面的S1中的当前字符，并在S1 '中加入一个空格。
Coming at the cell from above is the same as adding the character at the left from S2 to S2 ', while skipping the character in S1 above for now and introducing a space in S1 '.
来自左上侧的单元格，代表与左侧和上面的字符比对(可能匹配也可能不匹配)。
From the cell diagonally to the above-left, which corresponds to aligning the characters to the left and above (which might or might not match).
如果C1等于C2则为V3+1，如果 C1不等于 C2，则为 V3，其中 C1是当前单元格上面的字符，C2是当前单元格左侧的字符
V3 + 1 if C1 equals C2, or V3 if C1 is not equal to C2, where C1 is the character above the current cell and C2 is the character to the left of the current cell
如果采用特殊编码的某个字符的长度跨越了多个字节，则基于字符的字符串函数可以将每个字符处理为一个单元而不是一个字节序列。
If a character in a particular encoding spans multiple bytes, the character-based string functions can process each character as a single unit as opposed to a sequence of bytes.
可以指定一个可选的字符串长度单元来指明在哪些单元中表示函数的起始位置和结果。
An optional string length unit can be specified to indicate in what units the start and result of the function are expressed.
该函数包含两个参数，第一个参数是字符串，而第二个参数是代码单元。
The function includes two arguments, the first one being the string and second one the code units.
这个单元格上面的字符和左侧的字符相等(都是C)，所以必须选择2、3和3(左上侧单元格中的2 +1)的最大值。
The character above this cell and the character to the left of this cell are equal (they're both c), so you must pick the maximum of 2, 3, and 3 (2 from the above-left cell + 1).
待执行的字符串操作可能导致不同的输出，取决于计算字符所使用的字符串长度单元。
The string operation to be performed may result in different outputs, depending on the string length unit that is used for counting the characters.
在很多情形下，您需要根据代码单元计算的字符串长度，可以使用基于字符的函数来获取根据字符串单元计算的字符串长度。
In many situations, you need the string length in terms of code units, the character-based functions could be used to find the length of the string in terms of string units.
还了解了代码单元和基于字符的函数的概念。
You also learned about the concept of code units and character-based functions.
希望您使用新的SYSIBM函数路径，既便您没有使用字符串单元参数也是如此。
You are expected to use the new SYSIBM function path, even when you are not using the string unit argument.
起始位置指定了输入字符串中结果的第一个字符串长度单元所在的位置。
The start position specifies the position within input string that is to be the first string length unit of the result.
您也可以传递1来根据单元格制定完整的边界，或字符串以便说明特定的边界。
You could also pass 1 to draw a complete border around the cell, or a string to indicate specific borders' sides.
将字符看作一个单元而不是一个字节序列，这是进行多字节字符的字符串操作的必要条件。
Recognizing the character as a single, unit as opposed to a sequence of bytes, is a requirement in the case of string manipulations involving multi-byte characters.
使用OCTETS作为字符串长度单元时，通过简单地计算字符串的字节数即可确定字符串的长度。
When OCTETS is used as the string length unit, the length of a string is determined by simply counting the bytes of the string.
子字符串是输入字符串的零个或多个相邻字符串长度单元。
A substring is zero or more contiguous string length units of input string.
显然，如果每个工作单元都相当于单个字符串方法调用的两倍、十倍或一百倍，那么所花费的线程开销比例就相应地更小了。
Obviously, if each unit of work were two, or ten, or one hundred times as large as a single string method call, then the proportion of time spent in thread overhead would be correspondingly small.
例如，在图1和图2中，不同代码页中带点背景的单元格都表示同一字符集。
For example, in Figure 1 and Figure 2, the cells with dotted background in the different code pages represent the same character set.
OCTETS作为一种字符串单元指定不需要任何转换，而且使用起来更加有效。
OCTETS as a string unit specification does not require any conversion and is more efficient.
除了输入字符串之外，SUBSTRING函数还有其他三个参数，它们分别是：起始位置、长度和代码单元指定。
Along with the input string, the SUBSTRING function has three other arguments, which are start position, length, and code unit specification.
此函数与DB2 中的LENGTH 函数类似，并拥有一个可选的字符串长度单元，可以用来表示结果。
This function is similar to the LENGTH function in DB2 and has an optional string length unit, in which the result can be expressed.
