This principle originated from the system of ""one record did not bring a case to court two times "" in the ancient Rome law, and developed along different directions in two genealogies of law. In Common Law System, it named ""Non Bis In Idem""; and in Civil Law System, it named ""the principle against double jeopardy"".

它起源于古罗马法中的&一案不二讼&的制度，在两大法系沿着不同的方向发展，分别成为大陆法系既判力式的一事不再理原则和英美法系的禁止双重危险原则，其共同之处在于保护被告使其免于基于同一事实的国家权力的两次追诉。

Single component and multi\|component of iron system colloidal catalyst \Ali\|Bu\-3CH\-2CHCH\-2Cl\ were mixed by different ratios in hydrogenated gasoline medium at 25℃.This paper studied the relationship between the nonaqueous systematic electroconductivity and the concentration of catalyst components.In combination with Tyndall effect,polymerization experimental results,Ali\|Bu\-3 existed in associated state and dissociated into ionpair.The reaction between Ali\|Bu\-3 and Fenaph\-2 was the main reaction which formed colloidal core.Ali\|Bu\-3 reacted on CH\-2CHCH\-2Cl and Ali\|Bu\-2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Ali\|Bu\-3 was dissociated into ionpair which formed double electrode layer,and the double electrode layer kept the colloidal particles relatively stable.
