Abstract: Assuming that politics as well as economy of society is stable and personal physical condition is normal,the independent variables of personal social crisis function could be determined by means of dichotomy.Intelligence quotient,emotion quotient,knowledge stocking and morality can be selected as internal factors.Supposing aggregate valid population scale on crisis is G,subject’s influence or vote-getting on crisis is A,the scale of subject’s supporting group is P,the scale of subject’s antagonistic group is N,A/G and N/P could be deemed as external factors.Personal crisis function could be depicted as c=f(A/G,I,em,k,m;N/P),simplified as c=f(A/G,N/P).Crisis coefficient can be denoted by ε=W1/W2  or ε=U1/U2,W1  being the current expected welfare level without crisis,W2 the present welfare level under crisis,while U the utility.Crisis coefficient is employed to gauge crisis.

Key words: personal social crisis function, crisis coefficient, unknotting of personal social crisis
