中文摘要：
本文以预测过程中常常出现的冲击扰动问题为出发点，在灰色系统理论缓冲算子公理体系下，构造了一类弱化缓冲算子序列，对现有的弱化缓冲算子进行了整合，研究了这类弱化缓冲算子定义的内涵，实例验证了该算子序列的有效性和实用性，为解决冲击扰动系统在建模预测过程中出现的定量预测结果与定性分析结论不符的问题提供了可以借鉴的方法。
英文摘要：
The starting-point of the paper is shock-vibration problem which often appears in prediction,under buffer operator axioms of grey system theories, t- AWBO （t-power Weakening Buffer Operator） sequence is established which has the practicability, and some existing weakening buffer operators are arranged. Their characters and inherent relation are studied. An example shows their validity and practicability, the problem that some contradictions between quantitative analysis and qualitative forecast for shock-vibration data sequences is resolved effectively.
