1、合并字体
将电脑自带的宋体和Times New Roman字体合并为新字体，我命名为SongNTR.ttf
https://github.com/nowar-fonts/Warcraft-Font-Merger（上述网站可以合并字体）
2、将合并后的字体放置到matplotlib字体文件夹中
文件夹路径通过以下方式可以获得：
import matplotlib.pyplot as plt
import numpy as np
import matplotlibprint(matplotlib.matplotlib_fname())
输出路径：
c:\users\dell\appdata\local\programs\python\python38\lib\site-packages\matplotlib\mpl-data\matplotlibrc
3、修改matplotlibrc文件
文件位于 C:\Users\dell\AppData\Local\Programs\Python\Python38\Lib\site-packages\matplotlib\mpl-data
打开后修改257行和265行，其中257行去掉注释，265行去掉注释并添加字体 SongNTR
font.family: sans-serif
#font.style: normal
#font.variant: normal
#font.weight: normal

#font.cursive: Apple Chancery, Textile, Zapf Chancery, Sand, Script MT, Felipa, Comic Neue, Comic Sans MS, cursive
#font.fantasy: Chicago, Charcoal, Impact, Western, Humor Sans, xkcd, fantasy
4、修改.matplotlib缓存文件 fontlist-v330.json
位于 C:\Users\dell.matplotlib
打开后插入以下内容：
{"fname": "fonts\\ttf\\SongNTR.ttf","name": "SongNTR","style": "normal","variant": "normal","weight": 700,"stretch": "normal","size": "scalable","__class__": "FontEntry"},
4、重启python
5、测试
设置字体，实现中文：宋体，英文：Times New Roman
plt.rcParams['font.sans-serif'] = ['SongNTR'] ##设置字体
