步骤一:将下述常量数组定义为名称,如PY,下面就是包括26个字母及其第一个汉字: ={"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";" 夻","J";"咔","K";"垃","L";"呒","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";" 仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"}
复制公式或代码步骤二:使用LOOKUP(汉字,PY)或者VLOOKUP(汉字,PY,2)就可以返回指定汉字的拼音首字母:
(注意:使用VLOOKUP()函数时,其最后一个参数须用1或True的模糊“默认”查找方式)
如下,LOOKUP()的个数可根据汉字的个数决定,由于上面定义的PY最前面有一个""的值,所以可以屏蔽错误,当然也可以用迭代计算的方式获得: =LOOKUP(LEFT(A2),PY)&LOOKUP(
获取首字母需要对汉字表和字母表进行映射,如下示例代码是以gb2312编码为入手点,进行匹配的,也可以使用gbk、utf-8等编码进行匹配,但代码就完全不同了。
示例代码如下:
public class FirstLetterUtils {
// 简体中文的编码范围从B0A1(45217)一直到F7FE(63486)
private static int BEGIN = 45217;
private static int END = 63486;
// 按照声 母表示,这个表是在GB2312中的出现的第一个汉字,也就是说“啊”是代表首字母a的第一个汉字。
// i, u, v都不做声母, 自定规则跟随前面的字母
private static char[] chartable = { '啊', '芭', '擦', '搭', '蛾', '发', '噶', '哈', '哈', '击', '喀', '垃', '妈', '拿', '哦', '啪', '期', '然', '撒', '塌', '塌', '塌', '挖', '昔', '压', '匝', };
// 二十六个字母区间对应二十七个端点
// GB2312码汉字区间十进制表示
private static int[] table = new int[27];
// 对应首字母区间表
private static char[] initialtable = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'h', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 't', 't', 'w', 'x', 'y', 'z', };
// 初始化
static {
for (int i = 0; i < 26; i++) {
table[i] = gbValue(chartable[i]);// 得到GB2312码的首字母区间端点表,十进制。
}
table[26] = END;// 区间表结尾
}
// ------------------------public方法区------------------------
// 根据一个包含汉字的字符串返回一个汉字拼音首字母的字符串 最重要的一个方法,思路如下:一个个字符读入、判断、输出
public static String cn2py(String SourceStr) {
String Result = "";
int StrLength = SourceStrlength();
int i;
try {
for (i = 0; i < StrLength; i++) {
Result += Char2Initial(SourceStrcharAt(i));
}
} catch (Exception e) {
Result = "";
eprintStackTrace();
}
return Result;
}
// ------------------------private方法区------------------------
/
输入字符,得到他的声母,英文字母返回对应的大写字母,其他非简体汉字返回 '0'
/
private static char Char2Initial(char ch) {
// 对英文字母的处理:小写字母转换为大写,大写的直接返回
if (ch >= 'a' && ch <= 'z') {
return (char) (ch - 'a' + 'A');
}
if (ch >= 'A' && ch <= 'Z') {
return ch;
}
// 对非英文字母的处理:转化为首字母,然后判断是否在码表范围内,
// 若不是,则直接返回。
// 若是,则在码表内的进行判断。
int gb = gbValue(ch);// 汉字转换首字母
if ((gb < BEGIN) || (gb > END))// 在码表区间之前,直接返回
{
return ch;
}
int i;
for (i = 0; i < 26; i++) {// 判断匹配码表区间,匹配到就break,判断区间形如“[,)”
if ((gb >= table[i]) && (gb < table[i + 1])) {
break;
}
}
if (gb == END) {// 补上GB2312区间最右端
i = 25;
}
return initialtable[i]; // 在码表区间中,返回首字母
}
/
取出汉字的编码 cn 汉字
/
private static int gbValue(char ch) {// 将一个汉字(GB2312)转换为十进制表示。
String str = new String();
str += ch;
try {
byte[] bytes = strgetBytes("GB2312");
if (byteslength < 2) {
return 0;
}
return (bytes[0] << 8 & 0xff00) + (bytes[1] & 0xff);
} catch (Exception e) {
return 0;
}
}
public static void main(String[] args) throws Exception {
Systemoutprintln(cn2py("这是一个获取首字母的class"));
}
}
在EXECL中 ,按ALT+F11,插入---模块 复制下列代码 :
Function hztopy(hzpy As String) As String
Dim hzstring As String, pystring As String
Dim hzpysum As Integer, hzi As Integer, hzpyhex As Integer
hzstring = Trim(hzpy)
hzpysum = Len(Trim(hzstring))
pystring = ""
For hzi = 1 To hzpysum
hzpyhex = "&H" + Hex(Asc(Mid(hzstring, hzi, 1)))
Select Case hzpyhex
Case &HB0A1 To &HB0C4: pystring = pystring + "A"
Case &HB0C5 To &HB2C0: pystring = pystring + "B"
Case &HB2C1 To &HB4ED: pystring = pystring + "C"
Case &HB4EE To &HB6E9: pystring = pystring + "D"
Case &HB6EA To &HB7A1: pystring = pystring + "E"
Case &HB7A2 To &HB8C0: pystring = pystring + "F"
Case &HB8C1 To &HB9FD: pystring = pystring + "G"
Case &HB9FE To &HBBF6: pystring = pystring + "H"
Case &HBBF7 To &HBFA5: pystring = pystring + "J"
Case &HBFA6 To &HC0AB: pystring = pystring + "K"
Case &HC0AC To &HC2E7: pystring = pystring + "L"
Case &HC2E8 To &HC4C2: pystring = pystring + "M"
Case &HC4C3 To &HC5B5: pystring = pystring + "N"
Case &HC5B6 To &HC5BD: pystring = pystring + "O"
Case &HC5BE To &HC6D9: pystring = pystring + "P"
Case &HC6DA To &HC8BA: pystring = pystring + "Q"
Case &HC8BB To &HC8F5: pystring = pystring + "R"
Case &HC8F6 To &HCBF9: pystring = pystring + "S"
Case &HCBFA To &HCDD9: pystring = pystring + "T"
Case &HEDC5: pystring = pystring + "T"
Case &HCDDA To &HCEF3: pystring = pystring + "W"
Case &HCEF4 To &HD1B8: pystring = pystring + "X"
Case &HD1B9 To &HD4D0: pystring = pystring + "Y"
Case &HD4D1 To &HD7F9: pystring = pystring + "Z"
Case Else
pystring = pystring + Mid(hzstring, hzi, 1)
End Select
Next
hztopy = pystring
End Function
比如在A1输入 小燕子耳坠子78 则在其他空白单元格输入 =hztopy(A1) 回车执行即可
