rate of scale formation

Original construction method of concrete ring wall of large scale storage tank often has some problems such as big deformation and spacing deviation of reinforcing steel bars, being difficult to control ring wall curvature and low primary formation rate.

以往大型储罐基础混凝土环墙施工极易存在钢筋变形大，间距偏差大，混凝土环墙曲率难以控制，一次成型率低等问题。

A two-step turbulent combustion subgrid-scale model is employed for calculating carbon monoxide CO concentration, and the NO subgrid-scale pollutant formation model for the evaluation of the rate of NO formation. The heat flux model is applied to the prediction of radiant heat transfer.

化学反应速率由亚网格EBU燃烧模型来确定，两步亚网格紊流燃烧模型被用来确定CO浓度，NO亚网格污染物生成模型被用来评估NO生成速率，辐射热量传递采用了热通量辐射模型。

The kinetics of calcium carbonate scale formation has been studied based on the conductivity measurement including the rate of the nucleus formation and crystal growth as well as the influences of temperature and the scale inhibitors.

采用监测溶液电导率的方法，研究了碳酸钙的结垢速率，包括晶核生长速率和晶粒长大速率，以及温度和阻垢剂对碳酸钙结垢速率的影响。
