如何能让Out[187]像Out[94]那种格式输出？
二楼贴代码

In[93]:= Poisson := D[
#1, q]*D[#
2, p] - D[
#1, p]*D[#
2, q] &;
In[94]:= Poisson // TraditionalForm
Out[94]//TraditionalForm= \[PartialD]
#1/\[PartialD]q \[PartialD]#
2/\[PartialD]p-\[PartialD]
#1/\[PartialD]p \[PartialD]#
2/\[PartialD]q&
In[187]:=
Poisson[u[q, p], Poisson[v[q, p], w[q, p]]] //
Expand // TraditionalForm
Out[187]//TraditionalForm= u^(1,0)(q,p) v^(1,0)(q,p) w^(0,2)(q,p)-u^(0,1)(q,p) v^(1,0)(q,p) w^(1,1)(q,p)-u^(1,0)(q,p) v^(0,2)(q,p) w^(1,0)(q,p)+u^(1,0)(q,p) v^(1,1)(q,p) w^(0,1)(q,p)+u^(0,1)(q,p) v^(1,1)(q,p) w^(1,0)(q,p)-u^(1,0)(q,p) v^(0,1)(q,p) w^(1,1)(q,p)-u^(0,1)(q,p) v^(2,0)(q,p) w^(0,1)(q,p)+u^(0,1)(q,p) v^(0,1)(q,p) w^(2,0)(q,p)
