第一节物流基本概念 1963年成立时名称为“National Council of Physical Distribution Management(NCPDM)”。对物流管理( Physical Distribution Management)的定义:为计划、执行和控制原材料、在制品库存 及制成品从起源地到消费地的有效率的流动而进行的2种或多种活动 的集成。这些活动可能包括但不仅限于:顾客服务、需求预测、交 通、库存控制、物料搬运、订货处理、零件及服务支持、工厂及仓 库选址、采购、包装、退货处理、废弃物回收、运输、仓储管理

Important physical characteristics of MSW include specific weight, moisture content, particle size and size distribution, field capacity, and compacted waste porosity. The discussion is limited to an analysis of residential, commercial, and some industrial solid wastes. Note, however, that the fundamentals of analysis presented in this and the following chapter are applicable to all types of solid wastes

1.1 Physical Fundamentals This attenuation is usually expressed in decibels (dB). By definition, an attenuation of n dB means signal propagation from the that the original field strength is decreased by ite to the user by means of factor of 10-0In electromagnetic waves. Such waves Physical quantities
