本文根据著者在西北某电厂调查研究的资料论述了煤种多变和煤质下降对煤粉炉制粉和燃烧的影响。文中首先综述了煤质特性的变化情况。本文把煤质下降归结为三种情况:①水份增加;②灰份增加;④露头风化煤。接着讨论了制粉系统所受的影响。这种影响表现在制粉系统的磨煤能力和干燥能力方面。最后本文讨论了煤粉着火过程所受的影响。这种影响表现在一次风量和风速,回流区的温度水平等方面。

本文研究放大重油喷燃器时燃烧过程的模化法则。文中首先综述了燃烧模化的一般规律,著者认为完全模化是不可能的。其次指出,紊流扩散的准则数R_e保持相等是不合算的。然后,较详细地总结了佛立许的研究而引用了他的模化法则。根据这个法则,放大重油炉时紊流扩散恶化,因而燃烧条件允许的炉膛容积热强度降低。著者还分析了着火过程的模化原理而推导了着火稳定性保持不变的准则。文末附有一例题示出允许炉膛容积热强度的计算。

The breakdown processes of the flute-type hollow cathode discharge was observed by a low-light level TV eamera of the SEM (Silicon Electron Multiplication) type, the most sensitive one of low-light level cameras of modern industry. An explantion for the mechanism of light developmen was presented. The light development was divided into two stages, i.e., the stage (1st stage) of self-sustained dark discharge developed in the space between the anode bar and the outer-side of the flute tube, and the stage (2nd stage) of entering of dischage through the hole into the flute tube. Gorresponding to the two stages, there are two γ-processes, one existing at the metal surface around the hble and the other at the inner surface of the eathode. According to the above re-stilts, a discussion on the current principte of the design of geometrical parameters of the flute type was given.
