The results were as follows:Afterthe NH_4Y zeolite was dealuminated with Oxalic acid,the conversion of pinenespeeded up markedly, but the selectivity of camphene also dropped downmarkedly.After the NH_4Y zeolite was infused in solution of Mg(NO_3)_2,Zn(NO_3)_2 or Al(NO_3)_3 to remove corresponding oxide,the conversion rate of pinenedropped down,and the selectivity of camphene had little increase.

This language can be extended when components are well designed. By the introduction of a data type conversion function in the edge design and can-connect function in input terminal, the extended data flow language successfully solved the data conversion between different data types. It is a difficult problem in data flow language to realize conditional jump and recursion, however, by using the mechanism of active condition, this dissertation solves the problem well.
