最近投的一篇论文收到修改意见，有一个审稿意见是这样的：

Consider to always using signs when writing temperatures, e.g. "+25°C" instead of"25°C". Similalily, when a range is written, use "-20...+50°C"instead of "-20-50°C" (line 218 and other places).

对于零下温度加负号是毋庸置疑的，但对于零上的温度让我加正号，我不太同意审稿人的意见。我印象中很少有加正号的。而且，我查阅了许多论文和书籍，并没有加正号的，但是要拒绝审稿人意见，我不知道应该怎么说。不知下面的回复是否合适？

We thank for the reviewer’s comment. There is no question to add minus sign when writing temperature below zero. However, we find that most of papers and books do not add plus sign when writing temperature above zero. Anyway, we thank for the reviewer's thoughtful advice.
