1·This material could be the best solution for tertiary air duct elbow lining occasions.

解决了大型回转窑三次风管弯头的材料问题。

2·Moreover the efficiency of the fine particle separator is also poor with tertiary air containing too much pulverized coal.

且细粉分离器效率低，三次风带粉严重，故进行了技术改造。

3·Ultrafine pulverized-coal contained in the tertiary air was used as the reburning fuel and the oxygen level of the tertiary air was reduced with the use of flue gas recirculation(FGR).

本文在注蒸汽联合循环和余热锅炉型联合循环的基础上提出了采用烟气再循环和燃烧室回注水的燃气轮机循环，并对其进行了分析和优化。

4·This paper expounds the adaptibility of coarse sand filter with simultaneous air and water backwash to tertiary filtration plant.

阐述了粗石英砂气水同时冲洗滤池，在污水深度处理中的适用性。

5·Air lines as part or the tertiary sector can draw lessons herein; they can know customers better and narrow the gaps to improve service quality.

作为服务性行业的航空公司可从中进一步了解旅客的需要，减少差距，提高服务质量。
