【摘要】 利用微分不等式的方法，研究三阶积分微分程程三点边值问题：εｘ＇＇＇（ｔ）＝ｆ（ｔ，Ｔｘ，：ｘ，ｘ＇，ε）０≤ｔ≤１ｘ＇（０）＝Ａｘ（θ）＝Ｂｘ″（１）＝Ｃ其中：ε＞０是小参数；θ是介于０与１之间的常数；为常数。证明了解的存在性，并给出解的渐近估计式。更多还原

【Abstract】 This paper diseusses the three-points boundary value problems of the third order in-tegeral-differential equationswhere,ε>0 is amall parameter,E,θare contstants ,θare constants and in the inter-val(0,1).The exstence theorem is proved and an asymptotic estimation of the solution is givenby means of differential inequality method.更多还原
