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。

Parametric evaluation function can condense the complicated multi-objective and multi-constrait problem into a single-objective unconstrained problem, then solved with conjugate gradient method.The parametric evaluation function method decreases the optimization difficulty,and makes the solution away from the boundary of feasible region during the optimization process,which makes all the objectives optimized simultaneously.
