品位控制 meaning in English
grade control
Examples
- Grade control data collection , analysis and interpretation with a strong emphasis on qa / qc
采集、分析、解释品位控制数据；须注重质量评价和质量控制。 - This thesis primarily makes below the work of a few aspects : ( 1 ) the method that measuring and solution of the control point ' s coordinate , calculation of the point , solution of intersection with polygons , and calculation the quantity of ore reserves in a drawing file by computer technology ; ( 2 ) the theory and the method to draw the diagram of the equivalent line by establishing the abnormal triangle net , and ore blending with the diagram of the equivalent degree ' s line ; ( 3 ) the principle and method to automatically divide the ore , and the method to adjust to the quantity of ore and search the ore ' s information ; ( 4 ) adoption the line program to beg to solve the problem to ore blending , and establish the linear programming model and the simplification model with ore blending . ( 5 ) establish the control model with ore degree based on modem control theories
本论文主要完成了以下几方面的工作： ( 1 )利用计算机技术直接在一张现状图中，实现了控制点的测量与求解、坐标展点计算、多边形求交以及爆堆矿岩量的计算； ( 2 )提出了通过建立非规则三角网的方法来绘制等值线图的理论和实现方法，通过等品位线图指导配矿工作； ( 3 )提出了配矿块段自动划分的原理和方法，并在此基础上实现矿块矿量调整和矿块信息查询； ( 4 )采用线性规划的方法求解配矿问题，建立了配矿问题的线性规划模型和简化模型； ( 5 )建立了基于现代控制理论的品位控制模型。
