What is the difference between Ubuntu 16.04 and Ubuntu 16.04 LTS?
Some documents I read said they can just support Ubuntu 16.04, but when I googled for Ubuntu 16.04 image, I just found Ubuntu 16.04 LTS.

There is no difference between the two. Ubuntu 16.04 is the version number, and it is a (L)ong (T)erm (S)upport release, LTS for short. A LTS release is supported for 5 years after release, while regular releases are supported for only 9 months.
Every even year, the April release (hence the .04) is a LTS (examples: 12.04, 14.04, 16.04). The next upcoming LTS after 16.04 will be Ubuntu 18.04, codenamed 'Bionic Beaver', due to release in April 2018.
