The results show that the dynamic force and thermal conditions of forming the squall line were the convergence of cold air from Mongolia cold vortex and the warm-humid air current before west trough to form the convectional system at moderate 3 scale; the rapid development and southward shift of MβCSs was caused by a strong unstable stratification and the shear line of suitable vertical wind; a heavy hail occurred after a vertical liquid water content over 65 kg/m^2 was firstly measured by weather radar; a sharp reduction of VIL indicates that a disaster strong wind will occur at soon.

结果表明：蒙古冷涡旋转下甩冷空气与西风槽前的暖湿气流汇合，形成中p尺度的对流系统是飑线形成的前期动力和热力条件；强的不稳定层结和合适的垂直风切变导致了MβCSs的迅速发展和南压；在天气雷达首次观测到垂直液态水含量值超过65kg/平方公尺后2h内出现了大冰雹；垂直液态水含量的突然减小标志着灾害性大风的开始。

Franklin's life is full of charming stories which all young men should know — how he peddled ballads in Boston, and stood, the guest of kings, in Europe; how he worked his passage as a stowaway to Philadelphia, and rode in the queen's own litter in France; how he walked the streets of Philadelphia, homeless and unknown, with threepenny rolls for his breakfast, and dined at the tables of princess, and received his friends in a palace; how he raised a kite from a cow shed, and was showered with all the high degrees the colleges of the world could give; how he was duped by a false friend as a boy, and became the friend of all humanity as a man; how he was made Major General Franklin, only to resign because, as he said, he was no solider, and yet helped to organize the army's that stood before the trained troops of England and Germany.

富兰克林的一生充满了迷人的传奇故事，青年人都应该知道：他如何在波士顿街道上叫卖民歌唱本，而后来又成为欧洲各国君王的宾客；他如何逃票登船，然后靠做工抵偿船资才到达赞城，后来在法兰西却坐上了王后的轿子；他如何买三个便士的面包卷当早饭，在费城的街道上流浪，举目无亲，无家可归。后来却成为公王筵席上的常客，并且在宫殿里会见他的朋友；他如何从牛棚放起风筝，后来却荣获世界各大学所能给予的雪片般飞来的高级学衔；他在儿时如何被一个虚伪的朋友所欺骗，成年后却成为全人类的良友；他如何被任命为富兰克林少将，但他仅是说他不是军人就辞了职，然而却又帮助缔造了那支敢于同训练有素的英德联军抗衡的军队。

Also is long with one the attractive line to put in a clasp, after completes at home plays, first cramp iron substance in gate, holds on the line another head, made an effort a sliding door to close, I have traded a direction, as soon as then made an effort to pull, the gate has opened, this leafed door has become the automatic valve.

用一根又长又漂亮的线穿在一只钩子上，做好后在家里玩，先把钩子系在门上，拉住线的另一头，用力一拉门就关上了，我换了个方向，再用力一拉，门又开了，这扇门就成了自动门。
