Several practical considerations such as the discreteness of design variables are included in the optimization procedure. 对一些实际情况如设计变量的离散性问题作了合理的考虑。
There is a certain improvement of strength properties of CRM by redispersible polymer powder.But the test dates show larger discreteness and need the further research. 可再分散胶粉聚合物对橡胶水泥砂浆的强度等性能具有一定的改性作用，但试验数据表现出较大的离散性，需要做进一步的研究与探讨。
