摘　　要：目前，在科学计算领域有不少程序采用了Fortran和C＋＋两种语言进行混合编程（即“混编”），但现有混编的程序代码可读性差，可维护性差，严重影响了软件的可移植性和可重用性。针对此现状，笔者总结了自己在核电软件开发中的实际经验，分三步阐述了Fortran和C＋＋混合编程的规范化：首先，用宏定义等方法实现C＋＋类型与Fortran类型的映射；然后，对于简单类型的参数传递，提出规范性意见；最后，对于Fortran中的特殊类型，提出在C＋＋中用封装类型进行定义。经过对比验证，证明规范化的混合编程确实增加了代码的鲁棒性，可维护性。Nowadays in scientific computing, a mixed-programming technology with FORTRAN and C＋＋program language is adopted in many programs. While lots of mixed programs have the problems of bad readability and maintainability, so it have a bad influence on the reusability of software. According to the situation, author sum up experiences and come up with a solution how to improve the mix-programming by three step. Firstly, use a macro definition method to realize the type-map between FORTRAN and C＋＋. Secondly, to the base-type parameter passing, propose an idea about normalization. At last, propose a solution that use a C＋＋use-defined type for the special type in FORTRAN. By validating the results of before the normalization and after it, mixed-programming with normalization did improve the maintainability and robustness of the code.
