数学规划模型的建模语言（FQL）

对数学规划模型的结构作了深入分析。从纵向揭示了数学规划模型自然、清晰的层次结构；横向又把复合模型分解成若干基本模型，而基本模型又可由决策用户十分熟悉的二维形式加以描述。在此基础上，给出了建模语言（ＦＱＬ）的语法和语义。它除了具有建模能力外，消除了代数形式的索引；更重要的是具有数据库查询和模型操作能力。     

A ground‐level ozone forecasting model for Santiago,Chile

A physically based model for ground‐level ozone forecasting is evaluated for Santiago, Chile. The model predicts the daily peak ozone concentration, with the daily rise of air temperature as input variable; weekends and rainy days appear as interventions. This model was used to analyse historical data, using the Linear Transfer Function/Finite Impulse Response (LTF/FIR) formalism; the Simultaneous Transfer Function (STF) method was used to analyse several monitoring stations together. Model evaluation showed a good forecasting performance across stations—for low and high ozone impacts—with power of detection (POD) values between 70 and 100%, Heidke's Skill Scores between 40% and 70% and low false alarm rates (FAR). The model consistently outperforms a pure persistence forecast. Model performance was not sensitive to different implementation options. The model performance degrades for two‐ and three‐days ahead forecast, but is still acceptable for the purpose of developing an environmental warning system at Santiago.

HKD-1型航空润滑油的粘温特性

利用SYP1003型运动粘度测量器测量了HKD-1型航空润滑油在不同温度时的运动粘度，提出了粘度与温度之间的新关系式，并与Walther粘温模型进行了比较。结果表明：HKD-1型航空润滑油的粘度随温度升高而减小，其在低温时粘温特性较差，适合于20℃以上时使用。新的粘温模型比Walther模型预测精度高，适用的温度范围宽，尤其低温时的计算精度远远高于Walther模型。

A new model for the life prediction of GH4133 under TMF conditions

Thermal mechanical cyclic strain tests were carried out under in-phase and out-of-phase conditions on a Nickel-base Superalloy GH4133 in the temperature range of 571-823℃. Based on analyzing the present models of TMF (thermal mechanical fatigue) life prediction, a new model for predicting nickel-base superalloy TMF lifetime was proposed.TMF life of superalloy GH4133 was calculated accurately based on the new model. Experimental TMF life has been compared with the calculatedresults and all results fall in the scatter band of 1.5. The calculating results show that the new model is not only simple, but also precise. This model will play great roles in life prediction of the metal materials and the engineering components subjected to non-isothermal service conditions.
