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.

相比其它现有的数据流语言，扩展数据流语言具有以下特点：元件设计中定义了一种可激活函数，不同类型的节点允许定义各自的可激活条件，通过合理设计虚拟仪器元件，可以扩展语言的功能；在边的定义中引入类型转换函数，在输入端的设计中引入可连接函数，从而解决了不同数据类型之间数据传递的问题；在数据流语言中实现条件分支与循环通常是具有挑战性的一个问题，本文采用可激活函数的机制给出了一种解决方法。
