MATER_v0-5-0

This is a demonstration dataset for review only. Its aim is to test the MATER model for a version >= 0.5.0. The vector sheet and historical_in_use_stock sheet have beed deleted. Recycling rate has one more aspect : object_composition. The init_non_exo_in_use_stock sheet has been added to replace more or less the historical_in_use_stock sheet.

本数据集仅用于评审演示，旨在测试版本不低于0.5.0的MATER模型。已删除向量工作表（vector sheet）与历史在用库存工作表（historical_in_use_stock sheet）。回收率（Recycling rate）新增了一项维度：物项组成（object_composition）。新增了初始非外生在用库存工作表（init_non_exo_in_use_stock sheet），以大致替代原历史在用库存工作表。
