普光气田飞仙关组地震反射系数特征及应用

普光气田是川东北地区最大的气藏之一,是一个受构造和岩性控制的复合圈闭气藏。通过对飞仙关组气藏的岩石学特征、地震反射系数变化特征以及地震响应特征等方面的研究,分析认为飞仙关组一、二段(T1f1-2)储集层物性较好,其地震反射系数比飞三段(T1f3)变化大,"亮点"和"暗点"反射特征表现明显,通过运用地震反射特征进行气田井位部署,应用后取得了较好的效果。     

Infra-red temperature measurement of bright metal strip using multiple reflection in a roll-strip wedge to enhance emissivity

In a continuous annealing furnace, strip temperature was measured using radiation thermometers aimed, at a shallow angle to the strip, into the wedge-shaped cavity formed between the strip and a roll. The dependence of the observed temperature on thermometer operating wavelength, field-of-view, aiming and polarisation was investigated. Comparison was made against reference temperatures taken with a surface pyrometer and also derived from strip metallurgy. Control of the furnace, using a wedge thermometer, was demonstrated. The technique is potentially applicable in a wide variety of bright metal processing furnaces.

Toward a more accurate and extensible colorimetry. Part V. Testing visually matching pairs of lights for possible rod participation on the Aguilar-Stiles model

The spectral power distributions of strongly metameric visually matching pairs of lights, at visual fields of 10° and 1.3° and luminances from 0.2–120 cd/m₂, are examined for possible rod participation, on the Aguilar-Stiles model, in the visual matches. We develop a method for computing visual jnds of predicted rod intrusion; i.e., an analytical expression for rod mismatch. With this, we compute possible rod mismatch for 922 metameric pairs of lights, each pair pronounced a visual match by one or another of eight normal observers, by using the Trezona expression for pupil diameter or by arbitrarily assigning pupil diameters of 4, 6, 8, or 10 mm. We find some evidence of possible rod participation in the matches, under certain conditions, in small parts of the (brightness)-(fieldsize)-(spectral composition) three-space. On the Aguilar-Stiles model, rod participation is not an appreciable contributor to the troublesome tristimulus errors documented, in earlier parts of this series of articles, to be present at high and low field brightness and at large (10°) and small (1.3°) visual fields. © 1998 John Wiley & Sons, Inc.
