nonlinear plans meaning in Chinese

非线性规划

Based on the analyses of the investment of nozzle tube net and relationship between the annual operation cost and tube diameter function of a fixed spray irrigation system , a mathematic model to calculate the economical tube diameter of a spray irrigation system is developed by using the minimum expense norm and nonlinear planning theory in engineering economic analysis , and a direct calculation formula for the economical tube diameter in unrestrained conditions is presented
摘要在分析了固定式喷灌系统的管网投资、年运行费用与管径函数关系的基础上，利用工程经济分析中费用最小化准则和非线性规划理论，建立了求解喷灌系统管网经济管径的数学模型，并给出了无约束条件直接求解经济管径的计算式。
But the former is nonlinear combining optimal problem and the latter is nonlinear planning optimal problem . so it ' s prone to result in " combination exploration " and lower computational efficiency simply combining the above two means to carry on the coordination optimism of distribution network ' s reactive power
但一个是非线性组合优化问题，一个是非线性规划优化问题，因此用传统方法将这两者结合进行配电网络无功综合优化，容易产生“组合爆炸” ，而且计算效率低。
