废旧机械产品量大面广，考虑废旧机械产品广义生长的再制造服务是其合理充分利用的有效运行模式，但目前缺乏基础方法和系统研究。为此，本项目运用产品复杂度理论研究废旧机械产品广义生长规律和驱动特性，确定驱动因子和再制造服务模式；采用结构化分析方法对再制造服务活动、服务资源的业务逻辑关系进行描述，构建面向废旧机械产品广义生长的再制造服务过程模型；将废旧机械产品生长历程、再制造服务活动、再制造服务资源及三者间的映射与耦合关系进行参数化、知识化表征，建立其二阶三层映射模型；运用复杂网络、语义推理等，研究面向废旧机械产品

受介质非均质性制约，人们对岩溶优势渗流通道特征知之甚少，传统的泉流量衰减分析、室内物理模型模拟、数值模拟反演等研究方法，均不能精细刻画与再现岩溶水系统复杂的水动力过程。本课题采用回灌试验、水化学示踪、温度示踪、野外实时监测、孔内成像、孔内测速、电镜扫描、全直径岩芯孔渗分析、分层采样、流场分析、水文地球化学反演与数值模拟等方法，研究优势渗流通道—裂隙—小孔隙裂隙的空隙特征，研究优势渗流通道—裂隙—小孔隙裂隙释水的水力性质、水化学指标变化规律、水温变化规律。深入分析优势渗流通道的形成与孔喉特征、沉积特征、非均
