Based on the concept that the damaging degrees of eutrophication are related to the geological locations,hydrodynamic status and other conditions,a new concept of eutrophication sensitivity classification at small scale is proposed,which extends the control hierarchy of eutrophication from river-lake two-hierarchy to multi-hierarchy classification system.

Based on the sensitivity analysis of temperature control for typical pour blocks of a concrete dam,and the all process simulation of visco elastic 3 DFEM,the relationship between the maximum tensile stress of concrete blocks in a constraint region and the factors of temperature control (temperature of construction,time interval,start date and height of every layer)was obtained.

By using emulation visco-elasticity three-dimension finite element method,the sensitivity analysis of nine temperature control factors have been made in this paper and obtained that the top-temperature,the highest foundation temperature difference and the largest tension stress in the strongly constrained region of the concrete block were influenced by the change of temperature control factors.

The customer lifelong value model based on the sensitive analysis originates to the traditional model with a good operationality.

The algorithm innovatively introduces the group-aware idea into the real-time data aggregation application,and it can choose path satisfying the latency constraint dynamically with lower energy consumption than other existing algorithm through a special mechanism.
