Sorry for the stupid question, but i can't find a clear answer anywhere.
抱歉这个愚蠢的问题，但我在任何地方都找不到明确的答案。
When you merge two branches in git, you get an output like that :
当你在 git 中合并两个分支时，你会得到这样的输出：
some_file.txt | 564 ++++++++++++++--
I undestand that +and -mean addition and deletion, but :
我不明白 +，-意思是添加和删除，但是：
what does the number of signsrepresent ?when you have few changes, each sign seem to represent a line, but when you have more signs, i can't get the logic of the representation
is it some sort of percentage of changes ?My guess is that the number of signs represents a relative amount of changes - but relative to what ? current file ? the whole merge ?
how is it calculated ?Is there any officialsource about this ? The most accurate answer i had on this by now is "this representation is not very precise"... i'm just curious
什么迹象的数量代表什么？当你的变化很少时，每个符号似乎代表一条线，但是当你有更多的符号时，我无法理解表示的逻辑
是某种百分比的变化吗？我的猜测是，符号的数量代表了变化的相对数量——但相对于什么？当前文件 ? 整个合并？
它是如何计算的？是否有任何官方消息来源？到目前为止，我对此的最准确答案是“这种表示不是很精确”……我只是很好奇

It supposed to reflect the number of changes (in lines) to each file listed.
Plus signs for additions, minuses for deletions.
它应该反映列出的每个文件的更改数量（以行为单位）。
加号表示添加，减号表示删除。
EDIT:
the 564gives the amount of changed lines, and the -/ +gives you the proportion of deletions/additions.
When the amount of changes can fit a line you'll get '+' per addition, '-' per deletion;
Otherwise, this is an approximation, e.g.
编辑：
在564给出了改变线的量，-/ +为您提供了删除/添加的比例。
当更改量可以容纳一行时，每次添加都会得到 ' +'，每次删除都会得到' -'；
否则，这是一个近似值，例如
CHANGES.txt | 47 +++++++++++++++++++++++++++++++++
make-release.py | 77 +++++++++++++++++++++++++++++++++++++++----------------
2 files changed, 102 insertions(+), 22 deletions(-)
On CHANGES.txtsince you can see that there are no '-', and since 47 '+' are a lot you have a proportionate amount of them (i.e. 100%).
On make-release.pyyou'll see x39'+' standing for 55 additions and x16'-' standing for 22 deletions.
Exactly as their proportion, and just the amount to fit output screen.
在CHANGES.txt因为你可以看到有没有“ -”，并自47“ +”很多，你对他们有相当的数量（即100％）。
在上，make-release.py您会看到x39' +' 代表 55 次添加，而x16' -' 代表 22 次删除。
完全按照它们的比例，只是适合输出屏幕的数量。
Hope that helps.
希望有帮助。
