| 摘 要： | 本文通过对烟气测试中流速计算公式的比较分析，结合实际监测数据处理，认为烟气流速计算中，使用通用公式与简化公式的误差，虽然与Ｒｓ和Ｂｓ有关，但主要误差来源于Ｂｓ。而Ｒｓ不必用精密仪器测出烟气中各组份后求算。只要用简易仪器测得烟气中的Ｘｏ２和Ｘｓｗ的百分含量，即可求出Ｒｓ近似值，用于烟气流速计算。

| Abstract: | Through the comparision of flow velocity formulae in flue gas measurement and combining with monitoring data processing, it concludes that the main error comes from B_s even though errors caused by conventional formula or simplified one are related to R_s and B_s. R_s can be calculated approximately by Xo_2 and X_(sw) contents which can be measured with simple instrament. |
