So poor is the English translation that it messed the meaning of the problems of #147,especially 237D - T-decomposition.
Look at this sentence:_Let's define the cardinality of node xi as the number of nodes in tree s, containing in the node._ The "containing" should be changed to "contained".
What's more,this sentence:_There are obviously many distinct trees t, that are T-decompositions of the tree s._ It is quite abnormal to add "," ahead of "that".
As a result, these would mess the meaning and make our understanding difficult~
