Qualitative probability ( low, high ) values can be difficult to quantify. 定性的可能性(低,高)值非常难以量化。
Finally, according to the vulnerability assessment results and qualitative landslide probability, we got the landslide risk results during landslide failure stage under different conditions. 最后根据易损性评价结果和定性给出的滑坡破坏概率,得到了不同工况条件下失稳滑坡的风险结果。
This paper also derives the qualitative relation between matching probability of congruent terrain and different directions, which helps to improve the efficiency of navigability analysis. 并且分别得出了等方性好与差时,适配区域的匹配概率与方向之间的定性关系,有助于提高地形可导航性分析的效率。
The article also takes into consideration the probability of each risk and its influence on the project targets, regroups the four levels ' risks into three groups, then makes qualitative evaluation on the probability and damage. 本文还考虑到各风险发生的概率大小及其对项目目标实现的影响大小,将四级风险重新分为三组,对各组的风险概率和造成的损失大小进行了定性评价。
Modes of the suddenness blast-off of the engine are taken based on fault tree qualitative analysis, and the probability of the suddenness blast-off of the engine are obtained based on fault tree quantitative analysis. The analysis results are assessed at last. 定性分析获得了发动机意外点火模式和避免意外点火的有效模式,定量分析得到了发动机意外点火概率值,最后对分析结果进行了评价。
