    目前高效濾料多採用玻璃纖維濾紙，而近幾年來聚丙烯纖維濾紙發展較快，在標準濾速下（ 1cm s ） ，鈉焰法效率可達到99 . 999991 ，而其阻力在相同效率范圍內僅是玻璃纖維的1 6左右。
  10. Experimental results on butane and butane - plant oil flames indicated that, measurement precision by the multi - wavelength method is strengthened by taking radiation information on multiple wavelength units into consideration, and moreover, the radiation calibration procedure is simplified, in that a halogen light source is used instead of in situ flame radiation. in section 2, fluctuation and averaging analyses are carried out on optical transmission signals by particles passed through laser beams to derive particle size and concentration in measuring area, furthermore, correlation calculations are conducted on two adjacent laser beam signals to obtain flowing velocity of particle

    對丁烷氣體火焰及丁烷-植物油混合燃料火焰的測量結果表明，多波長分析方法優于傳統的雙色法，表現在兩個方面：一、由於綜合考慮多個波長單元上的火焰輻射信息，多波長方法的測量精度比雙色法有較大的提高；二、在多波長分析方法中，採用標準鹵素燈進行相對輻射強度標定，簡化了雙色法中的火焰絕對輻射強度的標定。
  11. In the aspect of thermal spraying processes the main techniques applied to water wall tubes include flame spray, arc spraying, plasma spray and high velocity oxy - fuel spray ( hvof ). flame spray possesses the characteristics of simple equipment, easy of use and low operating cost, but the coating adhesive strength is low, and porosity and oxidation is high

    在噴塗工藝方面，制備管道塗層的方法主要有火焰噴塗、電弧噴塗、等離子噴塗、超音速火焰噴塗等。火焰噴塗具有設備簡單、使用方便、操作成本低的特點，但它的塗層結合強度低，氣孔率及氧化物含量高。
