| 1. | But in fact their quantity values of the parameter indexes are often difficultly confirmed and they have fuzzy characteristics by theirself
但实际上这些参数指标的量值往往难以精确确定，本身具有模糊性的特点。 |
| 2. | Since 1980s , the application research of some fuzzy mathematic methods on the earthquake prediction have been developed in accordance to the fuzzy characteristic of the information during preparing earthquake
摘要20世纪80年代以来，针对地震孕育期间孕震信息的模糊性，国内开展了多项模糊数学方法在地震预测中的应用研究。 |
| 3. | According to the fuzzy characteristic of nonfinancial performance appraisal index , i use fuzzy general appraisal method to appraise the nonfinancial index under the weight - determined by ahp . i get impersonal conclution of the appraisal for nonfinancial index
然后根据非财务指标具有模糊性的特点，采用模糊综合评价的方法运用ahp法确定的权重对非财务指标进行综合评价，取得了比较客观的评价结论。 |
| 4. | ( 3 ) taking into account the fuzzy characteristics existed in selecting of the representative year , the fuzzy clustering method is adopted to the cluster analysis of year runoff data , and the cluster center vectors standing for the type of year , that is , abundant , moderate and deficient , are obtained
( 3 )考虑到典型年判定时存在的模糊性，将模糊聚类法用于年径流分析，由此求得分别代表丰、平、枯各种年型的聚类中心向量。 |
| 5. | The main achievements of this thesis are as follows : ( 1 ) studies the existed literatures home and abroad widely on risk assessment , the intension and extension about the five categories of uncertainty ( randomicity , fuzzy characteristic , gray characteristic , unascertained characteristic , universal gray characteristic )
取得的主要成果有： ( 1 )较系统地研究了国内外有关风险评估的理论、方法、技术成果和五种不确定性(随机性、模糊性、灰性、未确知性、泛灰性)的内涵、外延。 |
| 6. | Based on fuzzy characteristics in durability failure criterion of concrete structures durable life was estimated , in which process survival analysis method was considered with fuzzy theory and the contribution of statement of truncation data was taken into account
结合混凝土结构在耐久性评价中包含许多模糊性因素的特点，将模糊数学的思想融入到生存分析法中。基于结构的耐久性失效准则，并考虑删失数据的状态对混凝土结构耐久寿命的贡献，对混凝土结构的耐久寿命进行了统计分析。 |
| 7. | Based on the uncertainty and fuzzy characteristic of occurring of piping , fuzzy neural network of piping is proposed further . the same collected data is used to train and predict the model and gets good results , which proves fuzzy artificial network is also an effective method to predict and judge the occurring of piping
针对管涌发生的不确定性和模糊性，文中进一步建立了管涌的模糊神经网络模型，用同样的样本对模糊神经网络进行训练和测试，获得不错的预测结果，证明模糊神经网络也是预测判定管涌发生的有效方法。 |
