Query: A new class of plane symmetric solution   A new class of static plane symmetric solution of Einstein field equation
generated by a perfect fluid source is put forward. A special family of this
new solution is investigated in detail. The constraints on the parameters by
different energy conditions are studied. The classical stability of this
solution is discussed. The junction conditions matching to Minkowski metric and
Taub metric are analyzed respectively.
