Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

The force of low-level frontal zone disturbance is a major factor of the development of middle and low level cyclone. The large center of negative geopotential perturbation inversed by low-level disturbance potential vorticity is located in the front of cyclone providing a favourable condition for the eastward moving and development of cyclone. The high-level system plays a role of indirect force action. The interaction of the development of high-level trough and ridge and low-level frontal zone becomes an important mechanism of the developing of cyclone.

低层锋区扰动强迫是中低层气旋发展的最主要因子，低层位涡扰动反演所得的负位势扰动大值中心位于气旋的前方，有导前现象，为气旋继续东移、发展提供一个铺垫；高层系统起着间接强迫作用，高层槽脊系统的发展和低层锋区的相互作用所导致的斜压扰动成为气旋发展的重要机制。

On the basis of the distribution feature and the hypothesis about the radius of maximum wind within the circulation of a tropical cyclone,a lot of methods are designed to decide a tropical cyclone center with the pattern recognition technique.The aim of the applied study in operational tropical cyclone monitoring is to establish some objective positioning methods for the center of a tropical cyclone using a single Doppler radar radial velocity.

All of these provide scientific basis for development of the novel cyclone. At last, according to the thorough study of gas-solid process, The cyclone shape and size are improved, and the cyclone performances are taken better. The technique of cyclone with down-flow is updated, and applied in CFB boilers, retrofitting old boilers, CFB pulverized-coal gasifier, flue gas cleaner, and so on. The successful operation of 75T/h CFB boiler indicts that the novel technique tends to ripe.

Near the center, the pressure gradient force (from the pressure in the center of the cyclone compared to the pressure outside the cyclone) and the Coriolis force must be in an approximate balance, or the cyclone would collapse on itself as a result of the difference in pressure.

中心附近的气压梯度力（从压力中的中心气旋的压力相比，外气旋）和科氏力，必须在一个大致平衡，或气旋将会崩溃对本身所造成的差异在压力。

Dorothy felt as if she were going up in a balloon. The north and south winds met where the house stood, and made it the exact center of the cyclone. In the middle of a cyclone the air is generally still, but the great pressure of the wind on every side of the house raised it up higher and higher, until it was at the very top of the cyclone; and there it remained and was carried miles and miles away as easily as you could carry a feather.

他们的房子无疑就变成了狂啸龙卷风的中心地带，在通常情况下，在重心部位，空气是不流动的，但是受来自四面八方的狂风的巨大压力的影响房子越飞越高，一直到达龙卷风的风顶，它就在最后的高度上静止了，被风刮到一个特别遥远的地方，犹如飘落一根细小的羽毛，不费吹灰之力。
