【摘要】 在不定积分第二积分换元定理的条件中,要求变换x=φ(t)不含有稳定点,即:φ′(t)≠0.当变换x=φ(t)中含有孤立稳定点时,给出了变换中含有孤立稳定点的第二积分换元定理.拓宽了第二积分换元定理的应用范围.更多还原

【Abstract】 In the conditions of the second integral change element theory of indefinite integral,we demand transformation x=φ(t) can not contain stable point,namely: φ′(t)≠0.If transformation x=φ(t) contains isolate stable point,then this paper gives the second integral change element theory of transformation contains isolated stable point,which extend the apply scope of the second integral change element theory.更多还原
