本文是在北疆光弹实验研究基础上进一步取得的成果。研究得出ξ=0.5(R—R_1)·|σ_1+σ_2|方程,它揭示了地壳垂直构造反差强度与各地存在的地壳厚度及地壳中存在的主应力和的绝对值成正比的规律,并以此计算了北疆区域垂直构造反差强度,作出等值线图,在油区预测方面获得了一些新的认识。 This article is the result of further experiments on the basis of the northern bhaktioelastic experiment. The ξ = 0.5 (R-R_1) · | σ_1 + σ_2 | equation is obtained. It reveals that the crustal vertical tectonic strength is proportional to the existence of crustal thickness and the absolute value of the principal stress in the crust Based on this, the contrast intensity of vertical structure in the northern part of Xinjiang was calculated and the contour map was made. Some new understandings were obtained in the prediction of the oil region.
