Thanks for your answer.
 I find ?Global`* is useful.
And I work out like this:
Begin["a`"]
Y=H[Ky,Ly]
End[]
Names["a`*"]//MatrixForm


Sincerely

Depending on what you intend to do with the result, you could use ? or
Names. For instance, the following will give you all the user defined
functions and variables (located in the context Global by default)

In[1]:= f[x_] := x^2

In[2]:= g[x_, y_] := x^2 + y^2

In[3]:= ?Global`*

Global`
f	g	x	y

In[4]:= lst = Names["Global`*"]

Out[4]= {"f", "g", "lst", "x", "y"}

In[5]:= Definition /@ lst // TableForm

Out[5]//TableForm=
           2
f[x_] := x

               2    2
g[x_, y_] := x  + y

lst = {f, g, lst, x, y}
