基于区块链技术的关键性研究和技术改进，以及如何去推广(The key research and technology improvement based on block chain technology and how to promote it)

表达式求值程序，很好的实现表达式的ascii码输入，到数值计算(Expression evaluation procedures, to achieve a very good expression of the ascii code input to the numerical calculation)

说明：  隔离变压器和推挽变压器参数的设计，通过将变压器设计中所用到的公式用代码编辑到系统中，可以更快的根据所需指标来获取相应的参数，而且本系统中还集成了部分磁芯型号的相应参数和导线的参数，实现快速选取导线和磁芯，加快了变压器参数设计的周期，而且系统采用Visual Basic 6.0来设计界面，可以使设计人员更易操作。(The system is the design of the parameters of isolation transformer and push-pull transformer. By editing the formulas used in the design of transformer into the system with code, the corresponding parameters can be obtained more quickly according to the required indicators, and the system also integrates the corresponding parameters of some magnetic core models and the parameters of wires, so as to realize the rapid selection of wires and magnetic cores and speed up the change. The design cycle of press parameters and the interface design of the system using Visual Basic 6.0 can make the designer easier to operate.)
