1、定义一个xml模板（注意：这个导出的实际还是个XML，使用PowerPoint打开报错，导出pptx路径：
https://blog.csdn.net/xionglangs/article/details/120365758）
一、新建一个PPT，使用WPS或office另存为XML，替换后端的参数;
文本直接替换为${map key}
图片，后台存储Base64二进制流blip找上面的Relationship 的ID，Target路径对应pkg:part pkg:name
后台代码，使用的是模板生成PPT（包含后台直接生成PPT，但需要自己调整样式：）

注意：
1、此处不一定使用imageEntity，只是需要图片的二进制byte数组,不存在二进制图片，这 keyValueMap.put(“averageCellVoltageTimeImageBase64”, base64EncoderValue);不添加，否则打开PPT报已损坏
2、也可以添加一个空图片占位置，防止模板样式不对
