Analytical-parametric-based creep life estimation model combined with the Creep Factor approach was developed and integrated with an existing engine performance model to allow the estimation of various hot section component creep lives and the computation of the Creep Factors.
Many studies have been conducted in order to understand how these changes affect the creep life.
Using an analytical-parametric-based HP turbine blade creep life prediction model, the mechanical and thermal stress analyses were performed on the HP turbine blades.

Based on data analysis, the dynamical mechanical behavior of concrete with high temperature is affected by not only the strain rate effect whose influence keeps on decreasing with temperature increasing, but also the high temperature weakening effect.
According to the investigation, research findings in allusion to dynamic properties of concrete with high temperature are still rare.
In this paper, with the experimental system of high-temperature split Hopkinson pressure bar (SHPB) and microwave heating technique, a set of high temperature SHPB experiment technique is designed, multiple sets of tests at high and normal temperature are carried out, then the effect of temperature and loading velocity on mechanical properties are analyzed and compared, finally dynamical stress-strain curves of concrete with high temperature are obtained, and dynamical mechanical behavior is analyzed.
At temperatures below 600 ℃, the peak stress of concrete improves with the strain rate increasing under the same temperature, while at the same strain rate, the peak stress declines with temperature increasing; namely, it shows the significant strain rate effect and temperature effect in the dynamic mechanical properties of concrete with high temperature.
High-temperature concrete can be regarded as a porous material, the matrix material of which is aggregate with brittle characteristics and cement colloid, thus its dynamic mechanical properties will not appear in the plastic yield platform and dense stage (such as foam aluminum [18]), but in the compaction breakage stage.

Heat loss through solid boundaries is a key factor which determines the temperature of smoke layer at quasi-steady state and will be discussed in this paper.
Status of smoke layer might be affected by some points such as heat release rate of fire, exhaust rate, geometric and thermal conditions of the fire room and so on.
Heat loss of smoke layer through solid boundaries is a key factor which affects temperature of smoke layer at quasi-steady state of mechanical exhaust.
Model 2: Considering convective and radiative heat loss integratively A 2-layer zone model was proposed by YI[7] to calculate smoke layer properties with mechanical exhaust in an atrium.
In a fire room, The ratio of heat loss through solid boundaries to the convective part of fire power, χ, depends on the geometrical constraints, ventilation conditions, thermal properties of solid boundaries and others.

The process of scaling is mainly controlled by the composition and properties of produced fluid.
In this paper, we analyzed the relationship between scaling and the properties of produced fluid and established the warning mechanism for this problem.
This was also one of the key factors that caused the reduction of reservoir permeability.
Statistically analyzing the properties of produced liquid and scale composition in mechanical production wells in experimental regions.
The critical factors influncing the mechanical production well scaling are pH value, basicity, scaling cations and silicon content.
