结果表明，夏季海洋大陆赤道缓冲区的对流上升运动(90°E～120°E，5°N～5°S)、澳州大陆冷性高压(10°S～30°S，120°E～155°E)的发展，都影响2～3候以后105°E夏季越赤道气流；澳洲大陆北部的冷性高压，西太平洋副热带高压西端位置西伸或东缩造成的东中国海季风区上升运动的变化，又是南北半球环流同时影响CEF变化的具体表现。

The results show that wind divergence that is corresponding to the rain area forms at the windward side. After horizontal flow gets over the windward side, vertical circulation flow of climbing-ascending-descending form above the mountaintop. The ice crystal locates in the upper level, and below it there is snow and graupel, the cloud water and rain water is in the low level of the cloud.

此次暴雨过程的动力场、云和降水微物理过程的主要特征是：水平气流在迎风坡附近形成风场辐合，雨区与辐合区位置基本一致，垂直方向上出现明显的气流爬升—上升—下沉的中尺度环流。

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.

微物理过程对对流系统发展和维持有重要作用：强降水的雨滴蒸发过程会加强"冷池"效应，同时增强了雨带南侧原有的地面中尺度辐合线；凝结潜热在低层诱发了与回波相应尺度的中尺度低压，增强了辐合和上升运动，促进对流发展；霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程，降低对流不稳定能量，减缓对流发展；重力拖曳使气块冷却降温，降低对流不稳定能量，并且使低层的气压升高、气流辐散，在近地面附近产生出流，加强地面中尺度辐合线的强度。

On the basis of experiment analyses we would got that, When arc met with chute, it was blocked and had a stagnation, this made hot gas flow incrase near the chute; After arc went into the chute, mental vapor from arc root would lower the dielectric strength near the chute, meanwhile, High value of arc voltage and the corase face of the chute made electric strength increase. These factors might give rise to local restriking near the chute, and made arc voltage drop suddenly.

总结实验结果并加以分析，本文提出了这样的观点：电弧进入栅片时，在入口处受阻后的停滞，会使该区域的热气流增加；进入栅片后，弧根蒸发的金属蒸汽、电弧热气流会降低栅片入口区域的介质强度；电弧被栅片分割后，电压急剧上升，再加上栅片表面的不均匀会使局部区域的电场强度显著增加，这些因素的综合作用会导致电弧在栅片入口附近发生局部重击穿，引起电弧电压电压跌落。

For example,the spiral arrangement of scale－bract complexes on ovule－bearing pine cones,where the female reproductive organs of conifers are located,is important to the production of airflow patterns that spiral over the cone's su***ces,thereby passing airborne pollen from one scale to the next.

例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。
