The International Grief Questionnaire (IGQ): A new measure of ICD‐11 prolonged grief disorder
Journal of Traumatic Stress, Volume 37, Issue 1, Page 141-153, February 2024.Abstract Prolonged grief disorder (PGD) is included in the 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD‐11). This study sought to test the validity and reliability of a new brief measure to screen for ICD‐11 PGD—the International Grief Questionnaire (IGQ).

Complete convergence for ρ--mixing random fields(ρ--混合随机场的完全收敛性)
Zhejiang Daxue xuebao. Lixue ban, 2003 讨论了ρ--混合随机场的部分和完全收敛性.在一些适当的条件下,获得了较为一般的ρ--混合随机场的部分和完全收敛性定理,并得到了完全收敛速度与矩条件之间的等价关系.所得结果推广了ρ*-混合随机场和负相伴序列的相应结果.且将Hsu-Robbins型定理推广到ρ--混合随机场的情形.定理的证明基于Rosenthal型最大值不等式、Rosenthal型不等式、几个引理及缓变函数的性质.

Convergence of approximate solutions in stochastic programming(随机规划逼近解的收敛性)
Zhejiang Daxue xuebao. Lixue ban, 2000 本文对随机规划的逼近解的收敛性作了探讨，证明了当随机向量序列{ζ(k)(ω)}依分布收敛于ζ(ω)时，相应于ζ(k)(ω)的随机规划问题的任何最优解序列将收敛到原问题的最优解，这个结果对如何设计逼近算法提供了一个理论基础.

Zhejiang Daxue xuebao. Lixue ban, 2005 介绍一族避免二阶导数计值的带两个参数的迭代法来近似Banach空间中非线性方程的解.在与Newton法收敛相同的Lipschitz条件下，通过用一个递推关系证明了此迭代族的收敛，并给出了非线性算子方程解的存在惟一性定理.
