多次波衰减问题仅得到部分解决。一种最常见的多次波衰减方法是以拉冬变换为基础的。一个普遍接受的观点是抛物线型拉冬变换只能衰减具有较大时差的多次波。我们提出一种新的2-d方法,它能够在抛物线型τ-ρ域衰减与表面有关的多次波和层间多次波。该方法是以从一次波的波前特征得到的多次波模型预测为基础的。多次被预测包括以下几步: (1)对于一给定的多次波型式,对共炮点道集中每个接收器的一次反射估算出射角和波前曲率的半径; (2)对每个地检对确定组成一特定多次波至的中间点; (3)计算多次波的旅行时。预测的旅行时曲线附近时窗内的波场可以认为是我们用于多次波衰减处理的多次波模型。使用预测的多次波旅行时,我们可以确定包括多次波至主要能量的τρ域范围。通过τ-ρ空间每个样值与一非线性相似函数的简单相乘能够改善抛物线型拉冬算子的解。在本项研究中,我们通过将多次波模型的能量与τ-ρ空间的原始输入数据相比较来自动确定多次波抑制区。我们图示说明了此多次波衰减算法对合成资料和实际资料的应用。

了解与关键催化性能参数(如选择性和稳定性)相关的催化剂特性对于合理设计催化剂是非常重要的.本文重点考察了甲醇制烯烃(MTO)过程中MFI、MEL及其共生沸石分子筛的催化行为和构效关系.表征结果表明,丙烯和丁烯的高产率和MeOH的高转化率均与Pentasil分子筛结构中晶格Al位的富集相关,这也被27Al MAS NMR结果和3-甲基戊烷裂解结果证实.催化剂对MTO反应的催化性能与其晶体尺寸、外部B酸中心和铝配对等性质之间缺乏相关性,表明它们对提高丙烯选择性的作用不大.本文分析表明,催化剂失活非常复杂,受交叉点处晶格铝富集、总铝含量和晶体尺寸影响较大,且MFI和MEL相共生加速了催化剂失活.
