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.
