In the standard interactive physical programming procedure , the ability of physical programming to reach each point of the pareto surface evenly is used , and the interaction of the design procedure is conducted by modifying the boundary values of the design objectives " preference functions
在标准交互式物理规划中，利用物理规划可以均匀达到有效域中任何一点的特性，通过修改各设计目标偏好函数的边界值来体现设计过程的交互性。
The devices for detecting phase - to - ground fault in ineffectively grounded systems are seldom functionary at present . based on thousands of experiments in high - voltage laboratory in north china electric power university , the reasons for misjudgment and the effective measures to avoid it are presented in this paper : to change pt connection form to prevent from ill - effects of ferro - resonant overvoltage ; to increase soft measures to resist against interference ; to adopt neural network method to obtain the virtual value of the detect way
依据上千次实验，我们找到了一些导致选线误判的影响因素，并提出几点防止误判的措施，包括改变pt接线方式，避免铁磁谐振对选线的影响；通过对故障检测方式的处理和使用连续判断技术增强装置的软件抗干扰能力；尝试采用神经网络算法设定选线方法的有效域等。
