Annoyance rate ( ar ) and ar - based operations , i . e . expected ar ( ear ) and average ar ( aar ) , consist the major contents of the ar model 烦恼率模型包括两个主要内容：烦恼率和建立在烦恼率基础上的烦恼率期望值、烦恼率平均值运算。
The basis of ar model was complementally introduced in chapter 3 and through which different ar curves for several types of application purposes were suggested . another constituent of ar model , operations of ear and aar were defined based on a simple occupant counting and ar curves 论文第三章建立了烦恼率模型，同时也给出了适用于不同使用场合的烦恼率曲线，并在烦恼率曲线的基础上定义了烦恼率期望值和烦恼率平均值运算。
Our results show that as for which expected return models or approaches to measure abnormal performance - aar ( or car ) and bhar is more appropriate , and whether test statistics being misspecificated , there are different answers from the academic field , and the controversies still continue 研究发现，在各期望收益模型、两种度量异常收益方法aar （或car ）与bhar的选择，以及各检验统计量是否存在错误设定等问题上，国外学界并未达成共识，争论仍在继续。
On the basis of a reliable finite element model , the load spectrum as specified in aar standard and the s - n curve database for welding joints , regarding the new type of heavy haul open top wagon as the analysis object , fatigue life prediction is conducted in the design phase 基于可靠的有限元数值仿真模型，以及美国aar标准中的载荷谱、焊接接头的s - n曲线数据库，以重载新型敞车为应用对象，在设计阶段对其进行了疲劳寿命预测，预测结果表明该车确实存在疲劳寿命薄弱部位。
Combining on the investigation achievements of the base establishment concrete durability in shanxi province and the recent research situations of alkali aggregation reaction ( aar ) all over the world , on the condition of the same mortar fluidity , the preventing effects of mineral and chemical admixtures on aar were researched 结合陕西省混凝土耐久性调研成果及国内外目前混凝土碱?骨料反应研究现状，本文还详细研究了在相同流动度条件下矿物掺合料及化学外加剂对碱?骨料反应的抑制效果。
Abstract : controlling aar with high quality i grade fly ash has been researched . the result shows that the content is more important than the quality for the effect on controlling aar . the solubility of the fly ash contained alkali is inquired in differ alkali concentration solution . the mechanism of low content accelerating swell and yet high content controlling swell is discussed when controlling aar with the fly ash contained high alkali content 文摘:研究优质级粉煤灰对碱骨料反应的抑制效果，结果表明，用粉煤灰抑制碱骨料反应，其掺量因素的影响大于品质因素的影响；探讨了粉煤灰中的碱在不同浓度碱溶液中的溶出情况及用高碱含量粉煤灰抑制碱骨料反应时，低掺量促进膨胀，高掺量抑制膨胀的机理。
Founded in 1978 , aars promotes exchange and cooperation among researches on the technologies of satellite and aerial remote sensing and their applications in the study of environment monitoring , natural hazards and urban planning . currently aars has 23 asian country members and 19 associate members from other parts of the world 亚洲遥感协会成立于一九七八年，一直致力于促进亚洲各国科技界人士在卫星和航空对地观测技术及其在环境监测、自然资源、城市规划等应用领域的交流与合作，中国是该协会创始会员之一。
The research result indicated that on the condition of the same mortar fluidity , the preventing effects of mineral and superplasticizer compounded on aar are better than that of mineral used singly , the preventing effects of mineral admixture and entraining agent compounded are better than that of mineral admixtures used singly , the preventing effects of mineral and superplasticizer and entraining agent compounded are lower than that of mineral admixture and entraining agent compounded . the research achievement has some guiding sense on the recognition of aar prevention in pumping hpc and the researches of test methods for determining the alkali reactivity of aggregate used in hpc 研究结果表明：在相同砂浆流动度条件下，减水剂与矿物掺合料复合使用对碱?骨料反应的抑制作用大于矿物掺合料单独使用的抑制作用；引气剂与矿物掺合料复合使用对碱?骨料反应的抑制作用优于矿物掺合料单独使用的抑制作用；减水剂、引气剂与矿物掺合料三元复合使用对碱?骨料反应的抑制作用小于引气剂与矿物掺合料二元复合使用的抑制作用。
