| 摘 要： | 人类社群持久不衰的基本条件是资源点与知识点的不断集成。中华文明长盛不衰的秘密,从历史的角度来探讨,其要点在于:一个资源点(中原农耕之地)和两个知识/制度创新点(西北游牧民和中原农耕民)。当代中国的复兴不可能完全依赖于去复制前述历史条件,但是,新的资源点与知识点的不断集成这个条件,则是共通的。

| Abstract: | Effects of gas velocity, grid layer and wire distance on the mist separation efficiency of vibrating grid composed of stainless steel wires with a diameter of 0.2mm were studied, and the fabric filtration theory was introduced into the discussion of gas-liquid separation mechanism for the vibrating grid precipitator.It was found that the main separation mechanisms of single vibrating wire are the combined effect of both inertial impaction and interception. A theoretical formula about the mist separation efficiency of the overal grids was proposed. The experimental results show that gas velocity in the range of 3~5m/s has less effect on the separation efficiency, and the mist separation efficiency significantly improves with the increase of grid layer or the reduction of wire distance. |
