几何形状

Introduction 引言 The problems that occur while illuminating shallow offset parabolas, in addition to those related to the efficient use of parabolic generally, are additionally aggravated by the specific geometry of the parabolic mirror itself.

The research results are highly reproducible owing to the repeatable micro-model technique.(2) Quantifying the Kr-S-P curves in two-phase flow. The validity and adaptability of multi-phase curves are verified using micro-model testing bed tailored to adequate scale of pores. Results obtained from the P-S micro-model tests generally agree with the threshold values of displacement mechanism offered by researchers using geometric shapes. The hysteresis of .experimental Kr-S curves of numerous two-phase flows are depicted in terms of connectivity and humidification. The P-S and Kr-S curves of two-phase flow are well-derived in conjunction with micro-model test results and empirical van Genuchten model. For the curve expressing the relation between saturation and capillary pressure, experimental results of water-air flow system corresponds to the theoretical data.
