U-T training and test data for Saltblock model

Here are the training and testing data sets involved in the numerical experiments in the article that has been submitted to the journal “Journal of Geophysical Research: Solid Earth”, named “Joint Model and Data-Driven Simultaneous Inversion of Velocity and Density”: Saltblock model. Each dataset consists of two parts: a training dataset and a testing dataset. Both training and testing data sets contain three parts: seismic data, velocity model and density model.提交至《地球物理研究杂志：固体地球》（Journal of Geophysical Research: Solid Earth）、题为《速度与密度的联合模型与数据驱动同步反演》（Joint Model and Data-Driven Simultaneous Inversion of Velocity and Density）的论文中，其数值实验所涉及的训练与测试数据集为盐块模型（Saltblock model）。每套数据集均由训练数据集与测试数据集两部分构成；训练数据集与测试数据集均包含三个组成部分：地震数据、速度模型与密度模型。
