Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

The incidence of anxiety and depression in patients with FD was higher than that in healthy volunteers; The average extent of anxiety and depression of FD patients was significantly higher than that of healthy people (p 0.001). 2.The total scores of life events and the scores of negative life events in patients with FD was significantly higher than that of healthy group (p=0.014 and p 0.001), but the favorable life events scores was lower than healthy group's(p=0.001). 3. Eight healthy conceptions in the health-related quality of life of FD patients was significantly lower than that of healthy volunteers (p .001). 4. There was positive correlation among the symptom iterated integral, anxiety evaluation and depression evaluation of the FD patients (p0.001). 5. In the FD patients, there was no significant correlation between the evaluation of symptoms and life events. 6.

Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.
