But challenges arise concerning how to promote the process of popularization and realize the popularization of higher education:"great-leap-forward development and shortage of money","diversified social demands and single structure of higher education",and "equality in mass education and privilege in elite education".
The realization of equality and justice of socialist harmonious society depends on fair opportunity and openness of social stratum system, reasonable benefit enjoyment system and freely all-around individual development system.
This paper deals with a linear experiment with homogeneous equality constraints:Y=Xβ+ε,ε～ (0,σ~2V),Hβ=0.For a conditionally estimable linear fuction of the regression coefficients,all its Gauss-Markov estimators are given.
The concept of fuzzy equality , which is also called the equality relation[2,3], the fuzzy equivalence relation , the similarity relation [5,6] and the indistinguishable operator [7,8], and the fuzzy functions based on fuzzy equalities, has a significant concern in various fields, such as category theory and fuzzy control.
In this paper,the smallest real eigenvalue of the Hadamard product AB -1 of a M-matrix and the inverse B -1 of another M-matrix B were discussed. The inequality q(AB -1 )>1n·q(A)q(B) when B -1 is a matrix of main diagonal element complete equality were obtained.
The existence is proved of the integral solution to the indefinite cubic equation x31+x32+x33=y31+y32+y33 , and the p ositive integral solution is found to the indefinite cubic equation containing 3 6 equality signs with the same sums of the numbers on both sides of the equlity.
