The Cause - results Analysis for Importance - Possibility ( IPCA ) and It 's Applications

重要度-可能度因果分析方法及其应用

To proof the stability and security of IPCA system , this paper introduces the key system and the theory , structure of this system .

详细介绍了IPCA系统的原理和系统结构以及密钥体系，分析了它在提高安全性上采取的措施，证明它是一个稳定可靠的CA系统，有广泛的应用。

Puts forward a new method : Relative Importance-Possibility Cause-results Analysis ( IPCA ) for the system factors control .

综合考虑了系统因素的相对重要度与可能度，提出了一个新的相对重要度-可能度因果分析方法（IPCA）。

In the method , the distance ( denoted as D ) of a variety ( or genotype ) to the origin in the space of IPCA is used as an index of variety stability .

该方法是以一个品种（或基因型）在交互效应主成分轴（IPCA）空间中与原点的距离（记为D）作为该品种的稳定性指标的。

The AMMI model was used to analysis the locations for crop cultivars trial with parameter D j which was got from the environmental value of significant IPCA . The discriminating ability of 16 locations of early season indica rice cultivars trial in southern China in 1999 was analysed .

以AMMI模型中达显著水平的主成分轴上的环境分量Dj作为衡量区试点对品种的判别力的参数指标，对1999年南方稻区水稻区试早籼早中熟组16个区试点进行了分析。
