Part 2. Measurement of macular light sensitivity and FM 100-hue test in normal prese- nium and geratic people. The macular light sensitivity 、macular foveal light sensitivi- ty in 64 (82 eyes) and hue discrimination in 75 (100 eyes) normal presenium and geratic people were examined with macular threshold (white、red、blue and green color light) program of the Humphreh Field Analyzer and FM 100-hue test respectivity. The re- sults showed that the light sensitivity in four color light threshold was all declined with age. The mean error score square of each spectral region and whole spectral was increased with age, the loss of light sensitivity and hue discrmination was a linear correlated with age. The light sensitivity of the different field was compared, except blue color light threshold, the light sensitivity was decreased with the increasing of the eccentricity, white and red color light threshold in the inferior field showed lower sensitivity than that in the superior field.

The activities in different sections of the Gaoqing fault in the Huagou gas field were analyzed using 3D seismic data. The activities of the fault segment associated with the Huagou gas field were strong during the Guantao\|Minghuazhen period, while the activities on east and west sides of the gas field were weak at that time. The Huagou gas field is well corresponding to the strong activity segment of the Gaoqing fault on the plane. The process of gas migration in the Huagou reservoir is divided into two phases:(1)After mantle\|derived magmatogenetic gas including CO2, N2, and He entered the Gaoqing fault, the gas migrated to the top of the fault by the action of buoyancy or pressure, then the gravitative differentiation occurred. For the top of the fault is closed and both sides of fault is sealed, the gas assembled to some degree in the Gaoqing fault;(2)When gas was accumulated at a large scale in the Gaoqing fault, the gas migrated towards the reservoirs along the two sides of the fault and was accumulated in sandstone.
