  1. Result of numerical simulation shows that the grads of continuous phase " s velocities decreases with the presence of microbubble of which the diameter is 100 / / w, the profiles of air volume fraction in the boundary layers is similar to triangle or echelon, affected by interaction among the particle, there is a saturated air fraction, within the scope of saturated air fraction, increasing the air injection ratio can accrete the friction reduction ratio, under the condition of same air injection ratio, the free - steam velocity is larger, the effect of friction reduction is worse

    計算結果表明，直徑為100 m的微氣泡能減小近壁面連續相的速度梯度；微氣泡在邊界層中的濃度分佈近似為三角形或梯形分佈；受粒子間相互作用的影響，存在一飽和濃度；減阻率隨噴氣量的增大而增大，直至飽和噴氣量，此後，增大噴氣量，壁面摩擦阻力變化不大；相同噴氣量下，來流速度越大，減阻率越低。
  2. The characters and the stability of volume of air quench steel slag have been summarized first in this paper. the air quench steel slag has good physical and chemistrial properties, and can be used to prepare concretes as aggregate. at the same time, theoretical analyzation and experiment results also show that f - cao content is very low, and mgo exists in the ro phase, so the volume of air quench steel slag is stabile

    本文首先講述了風淬鋼渣的性質及其體積穩定性，指出風淬鋼渣具有良好的物理和化學性能，適合於作集料來配製混凝土；同時從理論上分析並通過試驗驗證表明，由於風淬鋼渣中游離cao含量很低，而mgo主要以ro相形式存在，不存在體積安定性不良的問題。
