How to get newline in \underbrace?

[Z.L.]

I am using LaTeX. In my paper, there is a equation as following form:

$\underbrace{My Equations}_{blablablabla}$.

Because the content "blablablabla" is too long to fit in underbrace, I
want to set a newline in it. I try to add a \\ in that, but it does'nt
take effect. I don't know if there is other way to deal with it.

Could anybody here give me some suggestions to solution to this
problem?
Thank you very much!

Z.L.

you could use

\underbrace{...}_{\substack{line 1\\ line 2}{

or subarray (I think) if you need it to be left aligned

..._{\begin{subarray}{l} line 1\\ line 2\end{subarray}}

or even a \parbox might do
