At present,the heavy academic workload of middle school students is a common problem,which is still questioned by parents,concerned by the government,and hotly debated by society.This paper summarizes the following eight aspects:the difficult content of subject courses,excessive class hours,heavy homework burden,complicated exams,overwhelming study materials,fierce subject competition,prevalent off-campus tutoring,and poor physical and mental health.Recognizing these problems can help to optimize the education and teaching environment and achieve a sustainable enrollment rate. 展开更多

运用四次Diophantine方程的性质以及初等方法证明了:设p是素数,当p■1(mod 8)时,方程y^2=px(x^2-4)仅有正整数解(p,x,y)=(3,4,12),(7,16,168),(3,98,1680)(3,6,24),(11,198,9240).若p≡1(mod 8)时,方程y^2=px(x^2-4)至多有一组正整数解... 运用四次Diophantine方程的性质以及初等方法证明了:设p是素数,当p■1(mod 8)时,方程y^2=px(x^2-4)仅有正整数解(p,x,y)=(3,4,12),(7,16,168),(3,98,1680)(3,6,24),(11,198,9240).若p≡1(mod 8)时,方程y^2=px(x^2-4)至多有一组正整数解.指出了万飞文章中的错误,并利用初等方法巧妙得出了一些新的结论,改进了Wenguan Wu,Alain Togbe,Bo He,Shichun Yang等的解的个数的上界. 展开更多
