You could enclose each text segment in a \pbox. Note, this requires the pbox package. This way you can treat each block of text as a math object.
\documentclass{article}
\usepackage{pbox}
\begin{document}
$\pbox{3cm}{Variation of\\ neutron number\\ in time} = \pbox{3cm}{Rate of\\ production\\ of neutrons} - \pbox{3cm}{Rate of\\ absorption\\ of neutrons}-\...

You can do that very simply with stackengine: its \Centerstack command is in text mode.
\documentclass{article}
\usepackage[usestackEOL]{stackengine}
\begin{document}
{\sffamily\[ \Centerstack[l]{ Variation of \\neutron number\\ in time}{}={}\Centerstack[l]{Rate of \\production\\ of neutrons}{}-{}\Centerstack[l]{Rate of\\ absorption \\ of neutrons} {}-{}\...

I think that this question is a duplicate of this: How do I typeset vertical and horizontal lines inside a matrix?
Here I put a small code where I have changed the parameters of vertical rules.
\documentclass[a4paper,12pt]{article}
\usepackage{mathtools}
\usepackage{amssymb}
\newcommand*{\vertbar}{\rule[-1.5ex]{1.1pt}{3ex}}
\begin{document}
\[\begin{...

I found that after installing those packages I had to got Lyx → Tools → Reconfigure. Now the Elsevier article class is available.

@scottkosty mentions 2 relevant bug reports 1 and 2, and the latter suggested passing in "reqno" as a document class option. This changes the equation labeling to the right side (instead of the left as shown) and avoids overlapping the equation label with the equation. Since I'm OK with right side equation label, this solves the issue for me.

Here's one answer, but it's a hack, and doesn't display fully right. You can break your table up into two tables, and make them exactly abut. Sometimes when I've tried to do this, I wound up with a weird indentation of one of the tables I couldn't clear, but undoing and redoing it again, carefully checking that the paragraph indentation was cleared at each ...

I just looked at the same thing and tried to use the 2cell feature in xy-pic. After reading the reference manual, I think the "right" solution is the following
\documentclass[border=10pt]{standalone}
\usepackage[all,2cell]{xy}
\UseAllTwocells
\begin{document}
\[
\xymatrix{C\drtwocell\omit{^<-2>\eta}\ar_{1_C}[dr]\ar^F[r]&D\ar^G[d]&
D\drtwocell\...
