结合带钢冷轧基本理论，选用适当的轧制压力模型，针对十六辊轧机轧制极薄带钢时的工艺特点进行了实验和分析，建立了相应的张力模型及辊系传动力矩模型；并得出变形抗力及压靠对轧制极薄带钢时的轧制力和板形有很大的影响，初步提出了当带厚较大时，为保持板形良好，随着轧件厚度的减少，轧制压力相应降低，当轧制到一定厚度时，轧制压力随着带厚的减少急剧增加的极薄带轧制分区理论。

It is also shown that one of the most important reasons of the heavy rain amplification is the cold air which spreads to south from midlatitude in the lower troposphere and transports into the typhoon low pressure. The study of PV on isentropic surface shows the active state of the midlatitude cold air. The tropopause folding, which means that high PV spreads downward from the upper troposphere or stratosphere, helps the releasing of potential instability energy and the development of rainstorm.

分析表明：对流层低层中高纬度冷空气扩散南下在台风低压环流区附近的"侵入"作用是此次特大暴雨过程的最重要的原因之一；等熵面位涡的分析进一步说明了中高纬地区冷空气的活动状况；对流层高层或平流层低层高位涡的下传有利于位势不稳定能量的释放，使得暴雨增幅。

You will catch cold if you wear miniskirt in such a cold weather.

这么冷的天气穿超短裙会感冒的。

"Ice on his forehead," is that the role of the skin by cold forehead, the nose can achieve vasoconstriction in order to stop bleeding, but its effects are not good, because bleeding from the nose position too far away, and local too does not give rise to the head cold, so the correct way is to direct ice in the "nasion" and "nose" above.

"冰敷额头"的作用是希望藉额头的皮肤遇冷时，能达到鼻部血管收缩以止血，但其效果并不好，因为距离出血的鼻孔部位太远，且局部过于冰冷会引起头部不适，所以正确的方法是可直接冰敷在"鼻根"及"鼻头"上面。

The interannual variation of winter negative accumulated temperature can be denoted in three periods of time: cold winters from the middle 1960s to the early 1970s; the transitional period of alternate cold and worm winters from the middle 1970s to the late 1980s; worm winters in the 1990s.
