reflection case

In the case of multiple-reservoir series whose vertical thickness is less than the tuning thickness, the multiple-reset-voir series can also be considered as a single thin bed, and its total thickness can also be determined by the composition reflection ampli-tude.

在多层储集层的情况下，只要其垂向分布范围在调谐厚度以内，应象单个薄层一样，也能利用复合反射波振幅求得多层储集层的总厚度。

When a thin interbed is thinner than 0. 1m, two groups of reflection waves merge into one, reflection energy weakens, and their waveforms are similar to those which appear in the case of fractures existing outside a borehole.

当薄层厚度小于0.1m时，两级反射波逐渐重叠变为一组反射波，反射波能量也逐渐减弱，并与井外存在裂缝时的波形特征相似。

This part mainly through scaffolding study in the United States of primary science implementation of the case analysis and reflection on the scaffolding learning theory that the use of our primary school of science curriculum implementation reference and enlightenment.

本部分主要通过对支架式学习在美国小学科学课程实施中的案例分析与反思，得出支架式学习理论的运用对我国小学科学课程实施的启示。

In the case of high frequencies, the sound reflection coefficient at sedimentary layer surface is simplified.

文末对高声频情况下的海底上的声反射系数进行了简化。

Then the one-dimensional linear prediction equation of vertical incident wave, under horizontally layered condition, is generalized to oblique incident case. Using the equation as a reference, the generalized spectral factorization equation of seismic inverse scattering for reflection dataset in a lateral inhomogeneous medium is deduced.

本文先将水平层状介质条件下垂直入射的一维线性预测方程推广到斜入射的情况，以此为参照，导出横向非均匀介质条件下反射数据的地震逆散射广义谱分解方程。
