周围有办法吗？我不是程序员。谢谢。

我在本地测试了你的文本，这很有效，我不是一个正则表达式专家，所以它可能不是最有效的。
使用“替换”标签（Ctrl+H）：
找到：^(.*?) ([A-Z].*$)
替换为：\1\r\n\2
确保选中匹配大小写和正则表达式。
解释：
找到：
^ starts with
. anything
* repeated 0 or more times
? lazy match so that it stops at the capital letter (next group)
(.*?) remember that part (group 1)
followed by a space
[A-Z] match the capital letter
. anything
* repeated 0 or more times
$ ends with
([A-Z].*$) remember that part (group 2)
替换为
\1 group 1
\r carriage return
\n new line
\2 group 2
答案 1 :(得分：0)
您需要使用regular expressions进行替换（查找空格后跟大写字母）。
在记事本++中使用正则表达式查找/替换（请务必选中“匹配大小写”）
找到什么：（[^。]）（[A-Z]） 替换为：\ 1 \ r \ n \ 2
答案 2 :(得分：0)
是，
使用perl脚本。这个让我觉得......
#!/usr/bin/perl
$cestbon = 0;
while (<>) {
@line = split(" ",$_);
if (/^$/) {
$cestbon = 0;
print "\n";
}
foreach (@line) {
if (/\b[A-Z][a-z0-9]*\b/ && $cestbon < 2) {
print "\n$_ ";
$cestbon++;
} else {
print "$_ ";
}
}
}
运行它！因为这是在MBP上，运行OS X又称UNIX。
