frontal wave

In this paper, based on the analyses of 41 severe local storm clusters which were associated withmeso-scale frontal waves between February and May from 1982 to 1988, their behavior and evolutioncharacteristics, the weather system model during clusters strong stage and the evolution patterns of cor-responding synoptic-scale cloud systems are given; finally, cluster movements are discussed.

本文分析了1982－1988年2－5月份的41例与中尺度锋面波动相关联的局地强风暴云团的活动和演变特征，给出了其强盛期天气系统配置模式及其在天气尺度云系演变中的表现型式，最后对其移动做了一般性讨论。

In drop tower experiments,a series of methaneair premixed Vflames of wrinkled flame fronts were observed in both normal gravity and microgravity conditions by the use of OHPLIF (Planer laser induced fluorescence for OH- radicals) to study the buoyancy influence.

借助于高速CCD摄像装置,在实验中记录了每一个火焰在正常重力和微重力下的大量火焰锋面瞬态图像。

The moving flame front(MFF-I)model,considering the surface reduction of carbon particle, locates the flame front only by analyzing oxidation.

考虑碳粒表面还原反应的移动火焰锋面模型(MFF-Ⅰ)在推导火焰锋面位置时,仅考虑了碳粒表面氧化反应的影响。

The method features three conditions, namely, the presence of a projection flame front, the irregular shifting motion of the latter s location, the variation of the latter s average gradient value.

根据煤粉燃烧理论及数字图像处理技术 ,提出用“投影火焰锋面存在”、“投影火焰锋面位置的窜动”以及“投影火焰锋面平均梯度值的变化”三个条件来诊断燃烧器火焰的ON/OFF状态 ,以用于燃烧操作指导和协助FSSS进行炉膛安全保
