I must say thank you very very much!

In fact I've been looking for \iint in ConTeXt in the last two days -_-
so i'll try to use \int\!\!\!\int instead of looking for a ConTeXt implementation :)

I met another problem today. Since there are not as many arrows in ConTeXt as there
in AMS-LaTeX,I don't konw how to type the formula in the attached picture which will
be referred in my presentation next Monday.

Hello, Xiao.

I'm glad I could help: I'm learning these advanced requirements as I go
along. My personal mathematics needs are much more modest.

I wouldn't give up on ConTeXt just yet. Try:
\loadmapfile[original-ams-base]
\starttext
\showmathcharacters
Note the \formula{\rightleftharpoons} and 
\formula{\upharpoonleft\!\downharpoonright}.
\stoptext

Do you know how you would code that cycle in (AMS)LaTeX?

Hi,
I  can code the cycle in ConTeXt,but it's too ugly and I will try to improve it.
here is my code:

\starttext
\placeformula
\startformula
\matrix{A+B&{\Delta G_1\atop\rightleftharpoons}&AB\cr
\Delta G_3\!\!\upharpoonleft\!\downharpoonright&&
\upharpoonleft\!\downharpoonright\!\!\Delta G_4\cr
A'+B&{\rightleftharpoons\atop\Delta G_2}&A'B\cr}
\stopformula
\stoptext

There is a similar example in "The TeXbook"(example 18.46).
You can try the follow code:

$$\def\normalbaselines{\baselineskip20pt
\lineskip3pt \lineskiplimit3pt }
\def\mapright#1{\smash{
\mathop{\longrightarrow}\limits^{#1}}}
\def\mapdown#1{\Big\downarrow
\rlap{$\vcenter{\hbox{$\scriptstyle#1$}}$}}
\matrix{&&&&&&0\cr
&&&&&&\mapdown{}\cr
0&\mapright{}&{\cal O}_C&\mapright\iota&
\cal E&\mapright\rho&\cal L&\mapright{}&0\cr
&&\Big\Vert&&\mapdown\phi&&\mapdown\psi\cr
0&\mapright{}&{\cal O}_C&\mapright{}&
\pi_*{\cal O}_D&\mapright\delta&
R^1f_*{\cal O}_V(-D)&\mapright{}&0\cr
&&&&&&\mapdown{\theta_i\otimes\gamma^{-1}}\cr
&&&&&&\hidewidth R^1f_*\bigl({\cal O}
_V(-iM)\bigr)\otimes\gamma^{-1}\hidewidth\cr
&&&&&&\mapdown{}\cr
&&&&&&0\cr}$$

Since i'm just a newbie of TeX, I don't really understand the first a few lines
of the solution. I still need some learning and practice :)
