It assumes survival time follow exponential distribution and quality of life initial value follow beta distribution. In order to correlate present quality of life with former quality of life, each quality of life were evaluations generated from AR(1) model. In addition, we set parameters of AR(1) model between 0 and 1, calculates expected QAST from different parameter combinations.

假设存活时间服从指数分布、生活品质初始值服从Beta分布,并利用时间序列一阶自我回归过程First-Order Autoregression Process, AR(1的模型产生各次生活品质评量值,使当次的生活品质与前一次的生活品质产生相关性,并将AR(1)模型中的参数设定为介於0与1之间的值,且产生不同的组合。

Using first order plug-flow reactor model, BOD5 removal rate constants of the whole wetland system were estimated to be 0.50 1/day (at 24℃) and 0.76 1/day (at 24℃) in the start-up and stable phase, respectively. These values were comparable to or even higher than the value of deoxygenation rate constant, 0.23 1/day (at 20℃), that is normally used in the river water-quality model.

由一阶柱塞流反应器模式(first order plug-flow reactor model)估算人工湿地系统启动阶段及稳定操作阶段的BOD5去除速率常数平均分别为0.50 1/day(24℃)及0.76 1/day(24℃),相当於或甚至高於一般河川水质自净模式中的BOD5脱氧速率常数的0.232 1/day(20℃)。

The new technique allows First Order Shear Deformation Plate Theory orClassical Plate Theory to be used for modeling built-up wing structures, sandwich wing structures or the wing structures which the volume between upper and lower skin is empty or solid with a'general planform.

根据翼面的几何和结构特点,新技术能够自主选择经典板理论(Classical Plate Theory,简称CPT)或第一阶剪切变形板理论(First Order Shear Deformation Plate Theory,简称FSDPT),具有模拟空心、实心、夹层和组合等形式的翼面结构及三维建模的能力。
