continuous differentiability meaning in English

连续可微性

In chapter two , we consider the non - ruin probability . in section one . by adapting the techniques in [ 5 ] , we obtain the integral expression of non - ruin probability in section two , firstly , we prove the twice continuous differentiability of non - ruin probability , then we obtain the integral - differential equation satisfied by ( u ) in section three , we introduce the auxiliary function e ( u ) . as u = 0 , gives 0
类似于[ 5 ]中的方法得到不破产概率满足的积分表达式在第二节中，首先证明了不破产概率的二次连续可微性，然后得到不破产概率满足的积分-微分方程由于不破产概率零初值时的值不确定，我们在第三节中引入了辅助函数e _ ( u ) ，使得u 0时， e _ ( 0 ) 0 。
