摘 要: 针对随机变量正态分布函数等的理想化情况,提出了限界修正的方法,并给出了线性函数修正和二次函数修正两种具体的修正结果。以美国AASHTO桥梁船撞设计指南中船舶碰撞概率的计算方法为例,说明了限界修正在工程领域中的重要性。 We presented a limited domain modification approach for the ideal condition of normal distribution of a random variable.We also proposed two concrete modification results of linear function and quadratic function modification.We further demonstrated the importance of limited domain modification of probabilistic density function in science and engineering,taking the computational method of vessel-bridge collision probability in USA AASHTO guide for bridge-vessel collision design as an example.
