扬程性能曲线的二阶多项式回归数学模型处理 - For the fuzzy controller with a fitted modifying factor , a third - order polynomial was used to approximate the former four modifying factors , without the quantization of input and output variables
在拟合修正因子模糊控制器中，采用一个3阶多项式对优化得到的4个修正因子运用最小二乘法进行逼近，且不再对输入和输出进行量化处理。 - Eno schemes are based on the approximation theory , which achieve high - order spatial accuracy by reconstructing piecewise smooth high - order approximate polynomial from the cell - averaging values . during the reconstruction , adaptive stencil technology , which automatically chooses the relatively smoothest stencil from all possible stencils , is adopted to guarantee essentially non - oscillation near the discontinuity
Eno格式基于近似理论，采用自适应基架技术(即自动选取所有基架中相对最为光滑的基架) ，对网格平均值构造分段光滑的高阶多项式来获得高阶空间精度，同时保证格式在间断附近具有基本无振荡性质。 - First , according to the orthonormal quality and the rational choice of working point of the sonar array three shafts frame , the structure of the models is predigested preliminarily ; secondly , according to the quality indexes and the coupling quality between frames , relatively small quantum is neglected . so the complex non - linear coupling models of the sonar array are predigested farther ; lastly , considering the characteristic of the model coefficient matrix , the methods of the low rank polynomial approach and the error simulation are introduced . so the models are predigested again
首先从声纳基阵框架结构的正交性和工作点的合理选择出发，使模型的结构得以简化；其次根据系统性能指标及框架间耦合性强弱，忽略相对小量，对声纳基阵复杂的非线性耦合模型进一步简化；最后考虑模型系数矩阵的特点，运用低阶多项式逼近和误差仿真的方法，实现了对模型的再次降阶简化处理。 - In the course of remote sensing digital image preparation , the paper , based on many experiments , chooses histogram match for radiation correction , texture filter method for strip noise reduction , and , with tm image in 1996 as the standard , carries out geometric correction and re - sampling of multi - band combined colored image by means of binary multinomial and closest pixel , with the error of one pixel
