Hi,
I have asked this question on tex.stackexchange.com
http://tex.stackexchange.com/questions/113592/formulas-in-context-are-different-from-those-in-plain-tex/113609?noredirect=1#comment250549_113609
as the title said, formulas typeset by ConTeXt are different from those
by plain TeX.
The minimal examples are here:
% plain luatex in ConTeXt standalone
$$\int_a^bf(x)dx=F(b)-F(a)$$
\bye
% context
\starttext
\startformula
\int\nolimits_a^bf(x)dx=F(b)-F(a)
\stopformula
\stoptext
Marco said to me that that's because the fonts used by LuaTeX and
ConTeXt are different. This can be seen from the pdf produced by them
pdffonts context.pdf
name type emb sub uni object ID
------------------------------------ ----------------- --- --- --- ---------
OLAZTU+LMRoman12-Regular CID Type 0C yes yes yes 18 0
RXHAAY+LatinModernMath-Regular CID Type 0C yes yes yes 19 0

DMNVHT+LMRoman10-Regular Type 1 yes yes no 7 0
MGKPYK+LMMathSymbols10-Regular Type 1 yes yes no 8 0
even if using the `modern-designsize-virtual` typescript(advice from
Marco), I still get the different outputs.
Now, I get confused about this qustion. If ConTeXt uses LuaTeX as its
engine, how can I tune ConTeXt so that it can produce the same formulas
with those in plain TeX?
you could define your own 'plain like' math setup using type one fonts
and families and all symbol names redefined or use the virtual lm instead
