查询词典 summation formula

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

提出了一种复杂含氧盐矿物的摩尔生成Gibbs自由能和摩尔生成焓的简单估算方法，并把复杂含氧盐矿物分为不含水复杂含氧盐矿物和含水复杂含氧盐矿物，不含水复杂含氧盐矿物可以看作是酸性氧化物和碱性氧化物组成的物质，其摩尔生成Gibbs自由能或摩尔生成焓都可以看作是酸性氧化物和碱性氧化物复合成的化合物摩尔生成Gibbs自由能或摩尔生成焓之和。

An S-shape acceleration/deceleration control model is developed by summation progression and the corner of two conjoint lines is adopted as a parametric variable to control the feedrate through the inflexion of two lines. Based on these, interpolation process is divided into two steps: interpolation pretreatment and interpolation point calculation. Feedrate planning is accomplished in the pretreatment step. Interpolation point calculating only depends on the real-time feedrate and the direction vector of the line.

该算法以级数求和的方法推导了S型加减速控制模型，并以小线段夹角为参变量控制拐点通过速度建立了小线段速度衔接模型，在此基础上，算法将插补过程分解为插补预处理及插补点计算两个步骤，预处理中对小线段进行速度规划并设计了线段速度的递推处理方法，插补点仅需根据当前速度及线段方向向量即可求出。
